Best Replacement Windows and Doors in Reston, VA

Why Reston Homeowners Choose Thompson Creek

Choosing the right window replacement company means more than comparing prices—it’s about finding a partner who stands behind their work for decades to come. Thompson Creek brings unmatched advantages that window resellers simply cannot match:

We Manufacture Our Own Windows. Unlike dealers who resell ProVia, Pella, or generic vinyl windows, Thompson Creek owns and operates our manufacturing facility. This means we control every aspect of quality, from frame extrusion to glass assembly. When you work with us, you’re dealing directly with the manufacturer—no middlemen, no markups, just exceptional value and quality assurance.

ENERGY STAR® Certified for Virginia’s Climate. Our windows meet or exceed ENERGY STAR requirements specifically for Virginia’s climate zone. With U-factors as low as 0.27 and advanced low-E coatings, Thompson Creek windows keep your home comfortable while reducing heating and cooling costs by 15-25% on average.

Custom Sizing at No Premium. Need windows for a non-standard opening? Bay window replacement in an unusual size? Our manufacturing facility allows us to custom-build windows to virtually any dimension without the excessive upcharges that dealers impose. This capability is especially valuable for Reston’s diverse architecture and older homes with unique opening sizes.

Understanding Northern Virginia’s Climate Impact on Windows

Reston sits in one of the Mid-Atlantic’s most challenging climate zones for windows. Hot, humid summers with temperatures regularly reaching 90°F test a window’s ability to block solar heat gain. Cold winters with temperatures dipping into the teens and twenties demand superior insulation to prevent heat loss. Spring and fall bring rapid temperature swings that cause inferior window frames to expand, contract, and eventually fail.

Why Summer Performance Matters. During July and August, Reston homes face intense solar heat that can drive cooling costs through the roof if your windows aren’t properly engineered. Thompson Creek windows feature low-E glass coatings with optimized Solar Heat Gain Coefficient (SHGC) ratings that block unwanted heat while still allowing natural light. This keeps your air conditioning from working overtime and reduces those painful summer utility bills.

Winter Insulation is Critical. When January temperatures drop below freezing, drafty old windows waste energy and create cold spots near beds and seating areas. Our windows achieve U-factors of 0.27 or better through advanced frame design, argon gas fills between panes, and warm-edge spacer technology. The result? Your home stays warmer with less furnace run time, and you’ll notice the comfort difference immediately.

Humidity Resistance Built In. Northern Virginia’s humidity can cause condensation, mold, and wood rot around poorly sealed windows. Thompson Creek’s composite frames resist moisture damage, and our professional installation ensures airtight seals that keep humid air where it belongs—outside your home. You won’t see the foggy glass or water droplets that plague cheaper window installations.

Designed for Temperature Swings. Spring and fall in Reston can bring 40-degree temperature swings in a single day. Inferior window frames expand in heat and contract in cold, creating gaps that let drafts through. Our frames are engineered with thermal stability that maintains their seal through countless temperature cycles, year after year.

Window Replacement vs. Glass-Only Repair: What Reston Homeowners Need to Know

When you notice a cracked pane or foggy glass, you might wonder whether you need glass-only repair or full window replacement. Understanding the difference helps you make the right investment for your home’s long-term performance and value.

When Glass-Only Repair Makes Sense. If you have relatively new windows (less than 10 years old) with modern vinyl or composite frames, and just one pane has cracked due to impact, glass replacement might suffice. This typically costs $150-$500 per pane and can be completed quickly. However, this is appropriate only when the window frame, sash, and seals are still in excellent condition.

Signs You Need Full Window Replacement. Most Reston homeowners actually need complete replacement rather than glass-only repair when they experience: foggy or condensation-filled glass between panes (indicates seal failure); visible drafts or curtains moving when windows are closed (frame deterioration); difficulty opening, closing, or locking windows (mechanical failure); chipped or peeling paint around frames (water infiltration damage); high heating and cooling bills despite a well-maintained HVAC system.

The Energy Efficiency Equation. Here’s what most homeowners don’t realize: replacing just the glass in an old window does nothing to improve the frame’s insulation, the weather-stripping, or the overall air sealing. A 20-year-old window with new glass is still a 20-year-old window. Full replacement with modern, energy-efficient windows can reduce your heating and cooling costs by 15-25%, paying for the installation within 7-10 years through utility savings alone.

Long-Term Value Comparison. Glass-only repairs might seem economical initially, but if your windows are more than 15 years old, you’re likely to face repeated repairs—another pane cracks, the frame starts leaking, the hardware fails. Full replacement with Thompson Creek’s lifetime warranty means you’ll never pay for window repairs again. We handle any future issues at no cost to you, for as long as you own your home.

Our Replacement Window Options for Reston Homes

Thompson Creek manufactures a comprehensive range of replacement window styles to match any architectural design, from the traditional colonials of North Point to the contemporary homes along Reston’s waterfront. Every window features our advanced frame construction, energy-efficient glazing, and precision engineering.

Double-Hung Windows. The classic choice for Reston’s traditional and colonial-style homes, double-hung windows offer timeless appeal with modern performance. Both sashes tilt inward for easy cleaning, and our advanced balance systems ensure smooth operation for decades. Low-E glass and argon gas fills deliver excellent insulation, while multiple grid patterns and color options let you match your home’s existing style. Perfect for bedrooms, living rooms, and any space where you want the flexibility of top or bottom ventilation.

Casement Windows. When you want maximum ventilation and unobstructed views, casement windows deliver. These windows crank outward to catch breezes, making them ideal for Reston’s pleasant spring and fall weather. Their compression seal (when closed, the sash presses tightly against the frame) creates superior energy efficiency compared to sliding windows. We often recommend casement windows for kitchens above sinks, in bathrooms, and flanking picture windows for both ventilation and architectural interest.

Bay Windows. Transform a flat wall into an architectural focal point with a bay window. These projecting window combinations add square footage, create window seating opportunities, and flood rooms with natural light from three directions. Thompson Creek custom-builds each bay window to your exact specifications—whether you prefer a gentle bow or dramatic angles. We frequently install bay windows in Reston living rooms, master bedrooms, and dining areas where homeowners want to make a statement.

Bow Windows. Similar to bay windows but with a gentler curve created by four or more window panels, bow windows create an elegant, sweeping appearance. The curved design works beautifully in Reston’s colonial and traditional homes, softening the architecture while maximizing natural light. Popular placements include front-facing living rooms, breakfast nooks, and master bedroom sitting areas.

Picture Windows. When you want to frame a view or maximize natural light without the need for ventilation, picture windows excel. These non-operating windows feature expansive glass areas with minimal frame obstruction. We often pair picture windows with flanking casement or double-hung windows—you get the view and light from the fixed center panel, plus ventilation from the operable side windows. Perfect for showcasing Reston’s wooded lots and seasonal beauty.

Sliding Windows. Ideal for wide openings where you want simple operation and contemporary style, sliding windows open horizontally with minimal effort. They work especially well in Reston’s modern and ranch-style homes. Since they don’t project outward like casement windows, they’re perfect above decks, patios, or anywhere exterior clearance is limited. Expect the same energy efficiency as our double-hung windows, with the convenience of single-action sliding operation.

Awning Windows. These windows hinge at the top and open outward from the bottom, creating an awning effect that lets you enjoy ventilation even during light rain. Reston homeowners appreciate awning windows in bathrooms for privacy ventilation, in basements where higher placement is needed, and stacked above or below larger windows for supplemental airflow without sacrificing wall space.

Garden Windows. If you love fresh herbs, starting seedlings, or displaying plants, garden windows project outward like miniature greenhouses. Glass on the top and sides maximizes sunlight, while a deep sill provides plenty of growing space. Kitchens are the most popular location, but we’ve also installed garden windows in breakfast areas and home offices where Reston homeowners want to bring the outdoors in.

Custom Shapes and Specialty Windows. Triangular gable windows? Circular windows? Trapezoid designs? Our manufacturing facility can create virtually any shape to match your Reston home’s unique architecture. We frequently work with homeowners in Reston’s diverse neighborhoods who need custom sizes for older homes or specialty shapes for architectural interest.

All Thompson Creek windows feature low-E glass coatings, argon gas fills, warm-edge spacers, and our advanced composite frames that resist warping, cracking, and fading. Choose from several exterior colors to complement your siding and interior finishes to match your décor.

Energy Efficiency That Pays: Thompson Creek Windows in Reston

Every Thompson Creek replacement window carries ENERGY STAR® certification specifically for Virginia’s climate zone. But what does that really mean for your Reston home, and how quickly will energy-efficient windows pay for themselves?

Understanding Performance Ratings. Three key measurements determine window energy efficiency: U-factor measures insulation (lower is better), Solar Heat Gain Coefficient (SHGC) measures heat transmission (lower is better in cooling-dominated climates), and Visible Transmittance (VT) measures light transmission (higher is better for natural light). Thompson Creek windows achieve U-factors as low as 0.27 (ENERGY STAR requires 0.30 or less for Northern Virginia), SHGC ratings around 0.25-0.30 for optimal summer performance, and VT ratings that maximize natural light without sacrificing thermal performance.

Low-E Glass Technology Explained. Low-E (low-emissivity) coatings are microscopically thin metal layers applied to glass that reflect heat while allowing light to pass through. During summer, low-E coatings reflect solar heat away from your home, keeping interiors cooler. During winter, they reflect your home’s heat back inside, preventing heat loss through the glass. You can’t see these coatings with the naked eye, but your utility bills will definitely notice the difference.

Argon Gas Fills for Superior Insulation. The space between window panes in our double-pane windows is filled with argon gas rather than regular air. Argon is denser than air and has lower thermal conductivity, meaning it insulates better. This invisible upgrade reduces heat transfer through the window by approximately 30% compared to air-filled windows. The argon seal lasts for decades, maintained by our advanced spacer systems.

Warm-Edge Spacer Technology. The spacer that separates glass panes in double-pane windows used to be aluminum, which conducted cold from outside directly to inside, creating condensation and energy loss. Thompson Creek uses warm-edge spacers made from insulating materials that virtually eliminate this thermal bridge. The result? No more condensation, ice, or frost forming at the edges of your windows during Reston winters.

Real Savings for Reston Homes. Based on Department of Energy data, replacing single-pane windows with ENERGY STAR certified windows saves Reston homeowners approximately $126-$465 annually. Even upgrading from older double-pane windows (pre-2000) to modern high-performance windows typically saves $125-$340 per year. For a whole-house replacement of 15 windows, you’re looking at annual savings of $200-$450, with payback periods of 7-12 years—well within the lifetime of your windows.

Comfort Beyond the Numbers. Energy savings tell only part of the story. Reston homeowners consistently report that their homes feel more comfortable after Thompson Creek installation. Cold spots near windows disappear. Rooms heat and cool more evenly. Outside noise drops noticeably. And on those hot July afternoons, your air conditioning actually keeps up. These comfort improvements are immediate and noticeable, long before you see the first utility bill savings.

Environmental Impact. Every Thompson Creek window installation reduces your home’s carbon footprint. Over a 20-year lifespan, energy-efficient replacement windows prevent approximately 1,500-3,000 pounds of CO2 emissions per window through reduced heating and cooling energy consumption. For environmentally conscious Reston residents, that’s a tangible contribution to sustainability that pays dividends for decades.

Our Proven Installation Process for Reston Homes

Thompson Creek’s installation process combines precision measurement, careful preparation, expert installation, and thorough cleanup to ensure your new windows perform flawlessly for decades.

Step 1: Free In-Home Consultation and Measurement (1-2 hours). Your Thompson Creek consultant visits your Reston home to assess your existing windows, discuss your goals, and take precise measurements of every opening. We’ll evaluate your home’s architectural style, show you samples of our windows and frame colors, and explain how different window types might enhance specific rooms. You’ll receive a detailed written estimate with no pressure tactics—our 40-year reputation speaks for itself, and we want you to make the right decision for your home and budget.

Step 2: Custom Manufacturing (4-6 weeks). Once you approve your project, we send specifications to our manufacturing facility where your windows are custom-built to your home’s exact measurements. This isn’t an off-the-shelf product modified to “close enough”—every Thompson Creek window is precision-engineered for your specific openings. We’ll contact you with an installation date approximately two weeks before your scheduled appointment, giving you plenty of time to prepare.

Step 3: Professional Installation Day (1 day for most projects). Our experienced installation crew arrives at your Reston home on schedule, typically between 8:00-9:00 AM. For an average 8-10 window project, expect installation to take 6-8 hours. Our process for each window includes: carefully removing the old window and disposing of debris; inspecting the rough opening for any structural issues that need addressing; preparing the opening with new weather-resistant barriers and insulation; installing the new Thompson Creek window with precise leveling and squaring; sealing all gaps with professional-grade caulking and expanding foam; installing new interior and exterior trim for a finished appearance. Throughout the day, our crew protects your floors, furniture, and belongings with drop cloths. We work room by room to minimize disruption and never leave openings exposed overnight.

Step 4: Quality Inspection and Homeowner Walkthrough (30-45 minutes). Before our crew leaves, the installation foreman conducts a detailed quality inspection of every window, checking operation, lock function, and seal integrity. Then you’ll join the walkthrough as we demonstrate how to operate each window type, clean and maintain your new windows, and answer any questions. We want you to feel completely confident in your new windows’ operation and care.

Step 5: Complete Cleanup and Debris Removal (included). We haul away all old windows, packaging materials, and installation debris. You won’t find scraps in your yard or garage. Our crew sweeps and vacuums around every window location, leaving your home cleaner than we found it. Many Reston homeowners tell us they’re amazed at how little disruption the installation causes—by evening, your home looks beautiful and feels more comfortable, with no lingering mess.

What Makes Thompson Creek Installation Different. Unlike subcontracted installation crews used by many dealers, Thompson Creek installers are directly employed by us and extensively trained in our specific window products. They use manufacturer-approved installation methods that preserve your lifetime warranty. Most importantly, they take pride in their work—you’ll see it in the attention to detail, the respect for your home, and the quality of the finished installation. We don’t rush jobs to fit more appointments into a day. Your installation gets the time it needs to be done right.

Serving Reston’s Diverse Neighborhoods

Thompson Creek has served every corner of Reston since the 1980s, and we understand the unique architectural characteristics and home styles throughout this 7,600-acre planned community.

North Point Village. The townhomes and single-family homes of North Point feature a mix of contemporary and traditional architecture. We frequently install double-hung and casement windows here, often helping homeowners balance HOA guidelines with maximum energy efficiency. North Point’s mature landscaping means we’re especially careful with exterior access and cleanup around established gardens.

Hunters Woods / Dogwood. Among Reston’s original neighborhoods, Hunters Woods showcases the community’s trademark clustered housing and wooded settings. The homes here often feature clerestory windows and unique architectural details that require custom window solutions. We’ve helped dozens of Hunters Woods homeowners maintain their homes’ mid-century modern character while dramatically improving energy efficiency.

Lake Anne. Reston’s historic core around Lake Anne Plaza includes some of the community’s most architecturally significant homes, including Hickory Cluster and the Heron House townhomes. Many properties here have large expansive windows taking advantage of lake and plaza views. We work carefully to match existing sight lines and architectural intent while upgrading performance. Some Lake Anne properties fall under historic preservation guidelines, and we’re experienced in meeting those requirements.

South Lakes. This family-friendly neighborhood features traditional colonial, contemporary, and transitional home styles with varied window configurations. South Lakes homeowners often choose bay and bow windows to enhance curb appeal, and we’ve completed numerous whole-house replacements here. The neighborhood’s proximity to South Lakes High School and excellent amenities makes home improvement investments particularly valuable for resale.

Tall Oaks. Known for luxury homes on larger lots, Tall Oaks properties often feature specialty windows, custom sizes, and complex window arrangements. Our manufacturing capability shines here—we can match virtually any size or shape needed for these distinctive homes. Tall Oaks homeowners appreciate our attention to detail and high-end finishing that matches their homes’ quality standards.

Reston Town Center Area. The urban townhomes and condominiums around Reston Town Center present unique installation challenges with limited exterior access and strict HOA guidelines. We coordinate closely with management companies, obtain required approvals, and schedule installations to minimize disruption to neighbors. Our crews are experienced in working in these tighter quarters while maintaining our quality standards.

Other Reston Neighborhoods We Serve. We’ve also completed hundreds of installations in Fairway Apartments, Fox Mill, Hidden Creek, Chimney House, Inlet, New Dominion, Shadowood, Stratton Woods, Sully Station, and virtually every other Reston neighborhood. No matter where your home is located, we understand the local architecture, HOA requirements (if any), and home styles that make Reston unique.

What Makes a Manufacturer Different from a Reseller

One of the most important decisions in your window replacement project is choosing a company that manufactures their own windows versus one that resells products from other manufacturers. Understanding this distinction helps you make an informed choice about quality, value, and long-term support.

Thompson Creek’s Manufacturing Advantage. We own and operate our own window manufacturing facility, where we control every step of the production process—from frame extrusion to glass assembly to final quality inspection. When you order Thompson Creek windows, we’re building them specifically for your home to your exact specifications. This vertical integration delivers multiple advantages you simply cannot get from window resellers.

Quality Control from Start to Finish. When a company resells someone else’s windows, they’re dependent on that manufacturer’s quality standards and have no ability to address quality issues during production. Thompson Creek inspects windows at multiple stages of manufacturing. If we spot any imperfection, we correct it before the window leaves our facility. This level of quality control ensures that what arrives at your Reston home meets our exacting standards, not someone else’s acceptable tolerance ranges.

True Custom Sizing Without Excessive Upcharges. Window resellers order from the manufacturer’s standard size charts. Need a window in a non-standard size? You’ll pay premium pricing—often 40-60% more—because the reseller has to pay the manufacturer’s custom upcharge and then add their own markup. Thompson Creek’s manufacturing facility lets us build windows to virtually any dimension as part of our standard process. You get perfect-fit windows without the excessive custom-sizing penalties that resellers impose.

Faster Response Times and Better Support. When something goes wrong with a resold window, the reseller has to contact the manufacturer, wait for authorization, order replacement parts, and coordinate the fix. This can take weeks or even months. When something goes wrong with a Thompson Creek window (rare, but it happens), we go directly to our manufacturing facility, make the part or replacement window, and get it to you quickly. No middleman delays, no finger-pointing between installer and manufacturer—just rapid problem resolution.

Single-Source Warranty Coverage. Resellers typically offer two separate warranties: the window manufacturer’s warranty (which they don’t control) and their own installation warranty (which doesn’t cover the product). If you have a problem, determining whether it’s a product issue or installation issue becomes a battle. Thompson Creek’s lifetime warranty covers both product and installation under a single umbrella because we control both. You call us, we take responsibility, and we make it right—no matter whether the issue stems from manufacturing or installation.

Better Value Without Dealer Markup. Consider the cost structure: A reseller buys windows from a manufacturer at wholesale (with the manufacturer’s profit built in), adds their own markup (typically 50-100% or more), and then adds installation pricing on top. Thompson Creek eliminates the middleman entirely. We manufacture our windows at cost, add a single reasonable markup, and include professional installation. The result is better value for comparable or higher quality windows. That’s why our prices are often 15-30% lower than comparable reseller offerings.

Direct Relationship Throughout Ownership. When you choose Thompson Creek, you build a relationship with one company—the manufacturer and installer. Ten years from now, when you need service or have questions, you call us directly. Resellers go out of business, lose manufacturer relationships, or stop servicing old installations. We’ve been manufacturing and installing windows in Northern Virginia for over 40 years, and we’ll be here for the lifetime of your windows.

Our Lifetime Warranty: Unmatched Protection

Thompson Creek’s lifetime warranty sets us apart from virtually every competitor in the Reston market, providing comprehensive protection that covers both the windows themselves and our installation workmanship.

What’s Covered Under Our Lifetime Warranty. Your Thompson Creek lifetime warranty includes: Window frame and sash (warped, cracked, or deteriorated vinyl/composite components); Glass seal failure (foggy or condensed glass between panes); Glass breakage (except impact/accidents); Hardware and locking mechanisms (failed or broken components); Installation workmanship (any issue resulting from improper installation); Weather-stripping and seals (deteriorated or failed seals causing drafts). This comprehensive coverage means you’re protected no matter what goes wrong with your windows—for as long as you own your home.

Product AND Installation Coverage—The Thompson Creek Difference. Most window companies offer two separate warranties: a product warranty from the window manufacturer (which the installer doesn’t control) and an installation warranty from the installer (which doesn’t cover the product). If you develop a problem, determining whether it’s a product defect or installation error becomes your headache, not theirs. Thompson Creek’s single comprehensive warranty covers everything—because we manufacture the windows AND install them. No finger-pointing, no jurisdictional battles, no passing the buck. You call us, we take responsibility, and we make it right.

Transferable to New Homeowners. Planning to sell your Reston home someday? Thompson Creek’s lifetime warranty transfers to subsequent owners, adding value to your property and peace of mind for buyers. During home inspections, recently replaced windows with lifetime warranty protection are significant selling points. Many real estate agents in Reston specifically mention Thompson Creek windows in listings because buyers recognize the brand and value the warranty protection.

Simple Claim Process. If you ever need warranty service, simply call Thompson Creek customer service and explain the issue. In most cases, we’ll schedule a service visit within a few business days to assess the situation. If the issue is covered (and the vast majority are), we’ll repair or replace the affected window at no cost to you—including labor. No deductibles, no service fees, no charges of any kind. We handle the repair professionally and completely, restoring your window to like-new condition.

40+ Years of Warranty Performance. A warranty is only as good as the company behind it. Thompson Creek has been manufacturing and installing windows in Northern Virginia for over 40 years. We’ve honored our warranty commitments for decades, and we’ll be here for decades more. Unlike fly-by-night contractors or resellers who come and go, Thompson Creek’s longevity gives you confidence that we’ll be here when you need us—in five years, ten years, or thirty years.

What’s Not Covered (Important to Know). Our lifetime warranty covers manufacturing defects and installation workmanship, but excludes: Glass breakage from impact or accidents (a baseball through the window isn’t covered); Damage from natural disasters (hurricanes, tornadoes, hail); Damage caused by modifications or alterations you make; Damage from failure to maintain (leaving windows open during storms, failure to clean tracks); Normal wear items like screens and exterior finishes (though these last decades with minimal care). These exclusions are standard in the industry and reasonable—we cover everything that could go wrong through no fault of your own.

Comparison to Competitor Warranties. When comparing window companies, carefully examine warranty details: Product warranties (how long? Lifetime or just 20-30 years?); Installation warranties (separate from product? How long? Lifetime or just 1-5 years?); Transferability (can new owners benefit?); Coverage scope (just the frame, or hardware and glass too?); Company longevity (will they be around to honor it?). Thompson Creek’s comprehensive lifetime warranty on both product and installation, fully transferable, covering all components, backed by 40+ years in business represents the strongest protection available in the Reston market.

Frequently Asked Questions About Window Replacement in Reston, VA

How much does it cost to replace a window in Virginia?

Virginia window replacement costs reflect regional labor rates and material costs specific to the Mid-Atlantic region. For Northern Virginia areas like Reston, expect to invest $850-$1,600 per window for quality replacement with professional installation. Specific window types in the Virginia market typically cost: Double-hung windows: $850-$1,400; Casement windows: $950-$1,600; Picture windows: $700-$1,500; Sliding windows: $800-$1,500; Bay and bow windows: $3,200-$7,000.

These Virginia-specific prices account for several regional factors. Northern Virginia labor rates run higher than rural Virginia areas due to cost of living and high demand for skilled tradespeople. Virginia’s climate zone (hot, humid summers and cold winters) requires higher-performance windows than milder climates, which increases material costs. Fairfax County and other jurisdictions may require permits for window replacement, adding $50-$150 to project costs (though Thompson Creek typically handles permitting for you).

Virginia homeowners should also factor in the long-term value equation. With Virginia’s temperature extremes, energy-efficient replacement windows reduce heating and cooling costs by 15-25% on average. Over a 15-20 year period, this energy savings can total $3,000-$6,000 for a whole-house replacement, effectively reducing your net window investment by those amounts. Additionally, Virginia may offer energy efficiency tax credits or utility rebates for ENERGY STAR certified window installations—ask your Thompson Creek consultant about current programs that could offset your investment.

How much should you expect to pay for windows?

Window replacement pricing depends heavily on window type, size, materials, and installation complexity. Here’s what you should expect to invest for common window types including professional installation:

By Window Type: Single-hung windows: $700-$1,100 (less expensive but less convenient than double-hung); Double-hung windows: $850-$1,400 (most popular choice for versatility); Casement windows: $950-$1,600 (premium pricing for superior ventilation and views); Sliding windows: $800-$1,500 (good value for wide openings); Awning windows: $750-$1,300 (specialty applications, often paired with other windows); Picture windows: $700-$1,500 (non-operating, great value for light and views); Bay windows: $3,200-$6,500 (architectural statement pieces); Bow windows: $3,500-$7,000 (elegant curved designs); Garden windows: $1,500-$3,200 (kitchen greenhouse windows).

Installation vs. Window-Only Costs: The pricing above includes professional installation, which represents 30-40% of the total cost. Some companies advertise window-only prices that seem dramatically lower, but you still need to pay for installation separately. DIY installation is rarely advisable for replacement windows—improper installation voids warranties, creates air leaks that negate energy efficiency, and can cause water intrusion leading to expensive repairs. Professional installation ensures your windows perform as designed and maintains warranty protection.

What Affects Your Specific Cost: Beyond window type, several factors influence your investment: Window size (larger = more expensive); Glazing options (double-pane vs. triple-pane, special coatings); Frame materials and colors (standard vinyl vs. premium finishes); Hardware and grid patterns (decorative options cost more); Installation complexity (height, accessibility, structural modifications); Number of windows (larger projects often include per-window savings). During your free Thompson Creek consultation, we’ll assess all these factors and provide a detailed written estimate specific to your home.

How much does it cost to replace glass in a window vs. full window replacement?

Understanding the cost difference between glass-only replacement and full window replacement helps you make the right choice for your Reston home’s long-term performance and value.

Glass-Only Replacement Costs: Replacing just the glass pane in a window typically costs $150-$500 per pane, depending on glass size, type (single-pane, double-pane, specialty glass), and accessibility. For example, a standard double-pane insulated glass unit (IGU) for a typical double-hung window might cost $200-$350 installed. This option makes sense only if your window frames are in excellent condition, the window is relatively new (less than 10 years old), and only the glass has failed due to seal failure or impact damage.

Full Window Replacement Costs: Complete window replacement with new frame, sash, glass, and hardware ranges from $700-$1,600 per window for standard sizes and styles, as detailed in previous FAQ answers. While this costs 2-4 times more than glass-only replacement, it delivers benefits that glass-only replacement cannot provide: new energy-efficient frames (old frames conduct heat/cold regardless of new glass), fresh weather-stripping and seals (glass replacement doesn’t address drafty seals), updated hardware and locking mechanisms, comprehensive warranty coverage on the entire window unit, and dramatically improved energy efficiency (15-25% utility cost reduction).

When Each Option Makes Sense: Choose glass-only replacement if: you have modern windows (installed within the last 10 years); only one or two panes have failed due to seal breakage or impact; the window frames, sashes, and hardware are in excellent condition; and you’re on a very tight budget and need a temporary solution. Choose full window replacement if: your windows are 15+ years old; you notice drafts even when windows are closed; you see condensation forming between panes (indicates seal failure); window frames show signs of deterioration, rot, or warping; windows are difficult to operate, don’t lock properly, or have broken hardware; or you’re looking to significantly reduce energy costs and improve home comfort.

Long-Term Value Comparison: Here’s what most homeowners don’t consider: replacing just the glass in an old window leaves you with 20-year-old frames, 20-year-old weather-stripping, and 20-year-old hardware. Within a few years, you’ll likely face additional problems—another pane fails, the frame deteriorates further, the hardware breaks. You’ll end up paying for multiple repairs over time, ultimately spending more than if you’d simply replaced the entire window initially. Full window replacement with Thompson Creek’s lifetime warranty means you’ll never pay for window repairs again, making it the superior long-term value even though the upfront cost is higher.

What are the most energy-efficient replacement windows for Reston’s climate?

Reston sits in a climate zone that challenges windows with hot, humid summers (regularly 85-95°F) and cold winters (often 15-30°F), requiring windows that excel at both blocking summer heat gain and preventing winter heat loss. The most energy-efficient windows for Reston homes feature specific performance characteristics that address these dual demands.

ENERGY STAR Requirements for Virginia: ENERGY STAR certification for Northern Virginia requires windows to meet or exceed: U-factor of 0.30 or less (measures insulation; lower is better); Solar Heat Gain Coefficient (SHGC) of 0.25 or less in some recommendations (measures heat transmission; lower is better for cooling-dominated climates, though Virginia is mixed). Thompson Creek windows achieve U-factors as low as 0.27 and SHGC ratings around 0.25-0.30, ensuring excellent performance in Virginia’s climate.

Key Features of Efficient Windows for Reston: Double-pane or triple-pane glazing (two or three layers of glass with insulating gas between); Low-E (low-emissivity) coatings that reflect heat in summer and prevent heat loss in winter; Argon or krypton gas fills between panes (better insulation than air); Warm-edge spacer systems that reduce heat transfer at glass edges; Advanced composite frames that don’t conduct heat like older aluminum frames; Multiple weather-stripping layers that create superior air seals. Thompson Creek windows incorporate all these technologies as standard features, not upcharge options.

Performance Metrics Explained: When comparing windows, look beyond just ENERGY STAR certification to actual performance numbers. U-factor measures how well a window insulates—Thompson Creek’s U-factors of 0.27 mean that only 27% as much heat passes through our windows compared to a single-pane reference window. SHGC measures how much solar heat passes through—our ratings around 0.25-0.30 mean only 25-30% of solar heat enters your home, keeping cooling costs down during Reston’s hot summers. Visible Transmittance (VT) measures how much light comes through—our windows achieve high VT ratings (around 0.50-0.60) so you get plenty of natural light without the heat.

Real Energy Savings in Reston Homes: Based on Department of Energy data, replacing single-pane windows with ENERGY STAR certified windows saves Reston homeowners approximately $126-$465 annually in heating and cooling costs. Even replacing older double-pane windows (pre-2000) typically saves $125-$340 per year. For a 15-window home, annual savings of $200-$450 means payback within 7-12 years—excellent return on investment given that quality windows last 25-30+ years. Beyond measurable energy savings, efficient windows eliminate cold spots near windows in winter, reduce hot spots in summer, minimize drafts, and cut outside noise significantly.

How long does window replacement take in Reston?

The window replacement timeline includes two distinct phases: the period from ordering to installation, and the actual installation day itself. Understanding both helps you plan appropriately for your project.

From Consultation to Installation (4-6 weeks typical): After your free in-home consultation and once you approve your project, Thompson Creek sends your specifications to our manufacturing facility where your windows are custom-built to your home’s exact measurements. This custom manufacturing typically takes 3-4 weeks. We’ll contact you approximately 2 weeks before your scheduled installation date to confirm timing and answer any questions. During busy seasons (spring and fall when weather is ideal), lead times may extend to 6-8 weeks, so planning ahead is advantageous if you have a specific timeframe in mind.

Installation Day Timeline: The actual installation timeframe depends primarily on the number of windows being replaced: 1-4 windows: 3-5 hours; 5-8 windows: 4-6 hours; 8-12 windows: 6-8 hours (full day); 12-20 windows: 1-2 days; 20+ windows: 2-3 days. These timeframes assume standard installation conditions (accessible windows, no major structural issues discovered, normal weather). Our crews typically arrive between 8:00-9:00 AM and work until the job is complete, including thorough cleanup.

What Happens on Installation Day: Your Thompson Creek crew will introduce themselves, review the day’s plan, and begin protecting your floors and furnishings with drop cloths. They’ll work room by room, removing old windows, preparing openings, installing new windows, sealing all gaps, and installing trim. Throughout the day, we never leave window openings exposed—each window is fully installed, sealed, and trimmed before moving to the next. This room-by-room approach minimizes disruption and prevents security concerns. Before leaving, the crew conducts a quality inspection, demonstrates window operation, and completely cleans up all debris. Most Reston homeowners are amazed at how quickly the transformation happens and how little disruption the process causes.

Factors That May Extend Timeline: Certain situations can extend installation time: Discovery of structural issues (rotted framing that requires repair before new window installation); Complex custom windows (large bays, bows, or specialty shapes take longer); High-altitude installations (second or third-story windows requiring special equipment); Weather delays (we don’t install in heavy rain, extreme cold, or high winds). If we discover any issues that will affect timeline or cost, we’ll discuss them with you before proceeding. Our goal is to complete your project efficiently while maintaining the quality standards Thompson Creek is known for.

Do I need a permit to replace windows in Reston, VA?

Window replacement permits in Reston (part of Fairfax County, Virginia) depend on the scope of work and whether you’re changing window size or location. Understanding permit requirements helps avoid potential issues during or after your project.

When Permits Are Required in Fairfax County: Generally, building permits are required for window replacement projects that involve: Changing the size of the window opening (making it larger or smaller); Relocating windows to different positions in the wall; Structural modifications to framing or load-bearing walls; Installing new windows where none existed before (new openings). For these projects, Fairfax County requires permit applications, plan reviews, and inspections to ensure compliance with building codes.

When Permits Are Typically Not Required: Replacing existing windows with new windows of the same size in the same locations—what’s called “like-for-like” replacement—typically does not require permits in Fairfax County. This covers the vast majority of residential window replacement projects. You’re simply upgrading to newer, more efficient windows without altering your home’s structure or appearance in ways that require county oversight.

HOA Approvals in Reston: While not a county permit issue, many Reston neighborhoods have homeowners associations (HOAs) with architectural guidelines. Some HOAs require approval for window replacement, particularly if you’re changing window style (grids vs. no grids) or exterior color. Thompson Creek is experienced in working with Reston HOAs and can provide the documentation they typically require for approval. We recommend checking your HOA guidelines and obtaining any required approvals before scheduling installation to avoid delays.

What’s the difference between vinyl and composite replacement windows?

Window frame material significantly affects performance, durability, appearance, and cost. Understanding the differences between vinyl and composite frames helps you choose the best option for your Reston home.

Vinyl Window Frames: Vinyl windows feature frames made from polyvinyl chloride (PVC), a durable plastic material. Quality vinyl windows (like Thompson Creek manufactures) offer excellent insulation, require virtually no maintenance (no painting, no scraping, no rot), resist moisture and humidity perfectly, and provide good value pricing. Modern vinyl manufacturing creates frames that won’t peel, flake, or corrode, and colors are integral to the material rather than painted on. In Reston’s humid climate, vinyl’s complete moisture resistance is a significant advantage—you’ll never see the rot, mold, or deterioration that can affect wood frames in Northern Virginia’s conditions.

Composite Window Frames: Composite frames combine wood fibers with polymer resins, creating a material that offers wood-like strength with better moisture resistance than natural wood. Composites can be painted to any color, offer excellent structural integrity for large window openings, provide superior thermal performance, and resist warping and deterioration better than pure wood. Thompson Creek’s composite frames deliver the strength advantages of wood with the low-maintenance benefits approaching vinyl.

Performance Comparison: Both vinyl and composite windows can achieve excellent U-factors (insulation ratings) and ENERGY STAR certification when properly engineered. Composite frames have slight thermal advantages in extreme temperatures due to their lower expansion/contraction rates. Vinyl excels in moisture resistance, making it ideal for bathroom windows, kitchens, and other high-humidity areas. Both materials dramatically outperform older aluminum frames (which conduct heat and cold readily) and match or exceed wood frames for insulation while requiring far less maintenance.

Appearance and Style: Vinyl frames traditionally came in limited colors (white, beige, tan), though modern manufacturing offers more options. Vinyl cannot be painted after installation, so you’re locked into your color choice. Composite frames can be painted or stained to virtually any color, offering more design flexibility. For most Reston home styles (colonial, traditional, contemporary), both vinyl and composite windows look appropriate and attractive. Composite frames can better replicate traditional wood window aesthetics if that’s important for your home’s character.

Durability and Lifespan: Both vinyl and composite windows from Thompson Creek are engineered for 25-30+ year lifespans. Vinyl won’t rot, corrode, or need painting—your maintenance is limited to occasional cleaning. Composite frames share these low-maintenance characteristics while offering slightly better impact resistance (important if you have children playing sports in the yard). Both frame types are covered by Thompson Creek’s lifetime warranty, so you’re protected regardless of which material you choose.

Cost Comparison: Vinyl windows typically cost 10-15% less than comparable composite windows, all else being equal. For most Reston homeowners on a budget, vinyl offers the best value combination of performance, durability, and cost. Composite windows make sense when you need the absolute highest structural performance (very large openings), prefer the option to paint windows in the future, or want the most wood-like appearance. Your Thompson Creek consultant can show you both options during your free in-home consultation and help you decide which best fits your priorities and budget.

Will new windows reduce my energy bills in Reston?

New energy-efficient replacement windows will almost certainly reduce your heating and cooling costs in Reston, with the exact savings depending on what you’re replacing and your home’s other efficiency factors.

Expected Savings Percentages: Department of Energy studies show that replacing single-pane windows with ENERGY STAR certified windows reduces heating and cooling costs by 15-30%. For Reston homes, this typically translates to annual savings of $200-$465. Even replacing older double-pane windows (installed before 2000) with modern high-performance windows saves 10-20%, or approximately $125-$340 annually. These percentages vary based on your home’s size, how much you heat and cool, and your utility rates, but virtually all Reston homeowners see measurable savings on their first full-year utility bills after Thompson Creek installation.

How New Windows Save Energy: Modern replacement windows reduce energy costs through multiple mechanisms: Superior insulation (U-factors of 0.27 or better) dramatically reduces heat loss in winter and heat gain in summer; Low-E glass coatings reflect heat back into your home during winter and block solar heat during summer; Argon gas fills between panes insulate better than air; Tight seals and quality weather-stripping eliminate drafts that make your HVAC system work harder; Warm-edge spacers prevent the thermal bridging that created cold spots around old windows. The cumulative effect of these technologies means your heating and cooling systems run less frequently and for shorter periods to maintain comfort, directly reducing energy consumption and costs.

Payback Period for Reston Homeowners: With typical energy savings of $200-$450 annually for a whole-house window replacement, and average project costs of $14,000-$24,000 for a medium-sized Reston home, simple payback periods range from 7-12 years. Given that quality replacement windows last 25-30+ years with Thompson Creek’s lifetime warranty coverage, you’ll enjoy 13-20+ years of “free” energy savings after the windows have paid for themselves. Additionally, energy costs tend to rise over time, making future-year savings larger than initial-year savings—speeding up actual payback.

Comfort Improvements Beyond Dollar Savings: Energy bill reduction tells only part of the story. Reston homeowners consistently report dramatic comfort improvements that, while harder to quantify, are immediately noticeable and highly valued: Cold spots near windows disappear (no more pulling curtains closed to block drafts); Rooms heat and cool more evenly (no more hot bedroom while the living room is comfortable); Outside noise drops significantly (traffic, neighbors’ conversations, lawn equipment become much quieter); Condensation and frost on windows disappear (eliminating potential mold and water damage); Furniture and flooring near windows no longer fade from UV exposure. Many homeowners tell us these comfort improvements alone justify the investment, with energy savings as an additional bonus.

Maximizing Your Energy Savings: New windows deliver the best energy savings when combined with other efficiency measures: Proper attic insulation (R-38 or better in Northern Virginia); Air sealing around other potential leaks (recessed lights, outlets, door frames); HVAC system maintenance (clean filters, annual tune-ups); Proper use of window coverings (cellular shades or insulating curtains boost performance); Smart thermostat programming (reduces heating/cooling when you’re away or sleeping). Thompson Creek offers several of these complementary services (roofing with proper ventilation, door replacement) that can further enhance your energy savings when bundled with window replacement.

What warranty comes with Thompson Creek replacement windows?

Thompson Creek’s warranty represents one of our strongest competitive advantages, providing comprehensive lifetime protection that covers both the windows themselves and our installation workmanship—a combination most competitors cannot match.

Comprehensive Lifetime Coverage: Your Thompson Creek lifetime warranty covers: Window frames and sashes (against warping, cracking, peeling, or deterioration of vinyl/composite materials); Insulated glass units (against seal failure that causes fogging or condensation between panes); Glass breakage (except from impact or abuse); Hardware components (locks, hinges, balances, cranks, and other mechanical parts); Installation workmanship (any issue resulting from improper installation, sealing, or finishing); Weather-stripping and seals (deterioration that causes drafts or water infiltration). This comprehensive coverage means virtually anything that could go wrong with your windows is covered—for as long as you own your Reston home.

Single-Source Warranty on Product AND Installation: Unlike most window companies that offer two separate warranties (product from manufacturer, installation from installer), Thompson Creek’s warranty covers everything under one umbrella because we both manufacture and install your windows. If you develop a problem five or fifteen years from now, you don’t need to determine whether it’s a product defect or installation error—you simply call Thompson Creek and we take full responsibility for making it right. No finger-pointing between manufacturer and installer, no jurisdictional battles about whose warranty applies, just straightforward problem resolution.

Fully Transferable to New Homeowners: If you sell your Reston home, Thompson Creek’s warranty transfers to the new owners, adding value to your property and providing powerful marketing appeal. Real estate agents in Reston often specifically mention recently installed Thompson Creek windows in listings because buyers recognize the brand quality and appreciate the continuing warranty protection. This transferability distinguishes Thompson Creek from competitors whose warranties are non-transferable or dramatically reduced upon home sale.

Simple, Straightforward Claim Process: If you ever need warranty service, just call Thompson Creek customer service at and describe the issue. We’ll typically schedule a service visit within a few business days to assess the situation. If the problem is covered under warranty (and the vast majority are), we’ll repair or replace the affected window at absolutely no cost to you—including labor. No deductibles, no service charges, no hidden fees. We’ll restore your window to like-new condition and ensure you’re completely satisfied with the resolution.

40+ Years of Warranty Performance: A lifetime warranty is only as valuable as the company standing behind it. Thompson Creek has manufactured and installed windows in Northern Virginia for over 40 years, and we’ve honored our warranty commitments for thousands of Reston homeowners throughout that time. Our longevity and financial stability mean you can trust that we’ll be here to honor your warranty in 5, 10, 20, or even 30 years. Unlike contractors who come and go, Thompson Creek’s four-decade track record provides confidence that your warranty protection is real and enforceable.

What’s Not Covered (Important to Understand): Our lifetime warranty covers manufacturing defects and installation workmanship, but excludes certain items that are standard industry exclusions: Glass breakage from impact, accidents, or abuse (baseballs, hail larger than 1″, deliberate damage); Natural disaster damage (hurricanes, tornadoes, floods, earthquakes); Damage from homeowner modifications or alterations; Damage from failure to properly maintain windows (leaving windows open during storms, never cleaning tracks or hardware); Normal wear and tear items like screens and grilles (though these last many years with minimal care); Damage from chemicals, solvents, or improper cleaning methods. These exclusions are reasonable and standard—we cover everything that could go wrong through no fault of your own, which is what homeowners need and deserve.

Can you match my existing window style for my Reston home?

Thompson Creek’s owned manufacturing facility gives us exceptional flexibility to match existing window styles, sizes, grid patterns, and colors—capabilities that window resellers often cannot provide or charge premium pricing to access.

Custom Sizing for Perfect Matches: Because we manufacture our windows custom for each project, we can build windows to virtually any dimension—including matching the exact sizes of your existing windows. This is especially valuable in older Reston homes where window openings may not match modern standard sizes. Resellers are limited to their manufacturer’s standard sizes and charge excessive premiums for custom dimensions. Thompson Creek builds every window to order, so non-standard sizes don’t trigger massive upcharges.

Grid Pattern Matching: If your existing windows have divided lights (grids or grilles), we can precisely match the pattern, spacing, and style. Options include: Colonial grids (6-over-6, 8-over-8, 9-over-6 patterns are most common in Reston); Prairie grids (perimeter grids with optional center cross); Custom patterns (any configuration you need for architectural consistency). Grids can be between the glass (maintenance-free, clean sightlines) or simulated divided lights (dimensional appearance on interior and exterior) to match your preferences and home’s architectural style.

Color and Finish Options: Thompson Creek windows come in multiple exterior frame colors to complement your siding and trim: White (classic, matches most Reston homes); Beige/Tan (warm neutral popular in traditional homes); Brown (rich appearance for earth-tone exteriors); Custom colors (available for specific architectural needs). Interior finishes can also be selected to coordinate with your décor, including white, woodgrain laminates, and other options depending on frame type.

Hardware Style and Finish Matching: Window hardware includes locks, handles, cranks (for casement/awning windows), and lift rails (for double-hung). We offer traditional and contemporary hardware styles in finishes including brushed nickel, antique brass, oil-rubbed bronze, white, and chrome. Matching your existing hardware style maintains architectural consistency throughout your Reston home.

Historical and Architectural Accuracy: Some Reston homes, particularly in the Lake Anne historic district, require specific window styles to maintain architectural character or meet preservation guidelines. Thompson Creek’s custom manufacturing capabilities allow us to create windows that satisfy these requirements while delivering modern energy efficiency that far exceeds the performance of original windows. We can replicate the appearance of traditional wood windows using modern materials that won’t rot, warp, or require painting.

Consultation Process for Style Matching: During your free in-home consultation, bring photos of your existing windows or windows from similar homes in your neighborhood that you’d like to match. Your Thompson Creek consultant will review your requirements, show samples of frame colors and grid patterns, and explain how we can replicate your desired style. In many cases, we can match your existing windows so precisely that only you will know which windows have been replaced—the exterior appearance remains perfectly consistent.

How do I choose the right window company in Reston?

Selecting a window replacement company is one of the most important home improvement decisions you’ll make, as windows directly affect your comfort, energy costs, and home value for decades. Here’s what to evaluate when comparing window companies in the Reston market.

Manufacturer vs. Reseller Distinction: This is perhaps the most critical factor. Companies that manufacture their own windows (like Thompson Creek) control quality from start to finish, offer true custom sizing without excessive upcharges, provide single-source warranty coverage, and deliver better value by eliminating middleman markup. Companies that resell other brands (ProVia, Pella, Andersen, etc.) are dependent on those manufacturers’ quality, standard sizes, separate warranties, and dealer markup structures. Ask any window company you’re considering: “Do you manufacture your own windows, or resell someone else’s?” The answer reveals a lot about quality control, customization capabilities, and value.

Warranty Comparison is Critical: Not all warranties are equal. Evaluate: What’s covered (just the product, or installation too?); How long coverage lasts (lifetime, or just 20-30 years?); Is it transferable to new homeowners?; Who backs the warranty (installer, window manufacturer, or both?); How long has the company been in business to honor warranties? Thompson Creek’s comprehensive lifetime warranty covering both product and installation, fully transferable, backed by 40+ years in business, represents the gold standard. Be wary of companies offering separate product and installation warranties—this structure creates finger-pointing when problems arise.

Local Experience and Reputation: Check how long the company has operated in Northern Virginia and specifically served Reston. Companies with decades of local experience understand Virginia’s climate demands, Reston’s diverse architecture, local building codes, and HOA requirements. They’ve also built reputations they must protect through quality work. Verify BBB ratings, read Google and Angie’s List reviews, and ask for references from recent Reston projects. Be cautious with newer companies or national chains without deep local roots—they may not be around to honor warranties in 10-20 years.

Installation Quality and Training: Ask about installer qualifications: Are installers employees or subcontractors?; What training do installers receive?; Are installers certified by industry organizations?; Will the same crew handle your entire project? Thompson Creek employs our own installation crews (not subcontractors) and provides extensive training in our specific window products and installation methods. This ensures consistent quality and accountability.

Transparent Pricing Without Gimmicks: Be extremely cautious with companies advertising “Buy One Get One” or “Today Only” pricing. These promotional gimmicks usually mean inflated base prices “discounted” back to normal (or higher than normal) rates. Reputable companies like Thompson Creek provide straightforward pricing year-round without pressure tactics. If a company claims their price expires today or offers dramatically different pricing if you “sign now,” that’s a red flag indicating manipulative sales practices.

Physical Location and Stability: Verify the company has a real physical location in the area, not just a P.O. box or virtual office. Visit their showroom if possible. Check business registrations, insurance coverage, and contractor licenses. This due diligence protects you from fly-by-night operators who disappear when warranty claims arise.

What’s the best time of year to replace windows in Reston, VA?

Thompson Creek installs replacement windows year-round in Reston, and modern installation techniques allow quality installations in virtually any weather. However, certain seasons offer specific advantages worth considering.

Spring (March-May) and Fall (September-November) are Ideal: Most Reston homeowners prefer spring and fall window replacement for several reasons: Mild temperatures (60s-70s) make the brief periods when windows are open during installation more comfortable; Lower humidity than summer makes working conditions more comfortable for installers; Moderate weather reduces weather-related scheduling uncertainties. These seasons are our busiest, so scheduling 8-10 weeks in advance is advisable to secure your preferred installation date.

Summer Installation (June-August) Works Well: Despite heat and humidity, summer window replacement offers advantages: Longer daylight hours give installation crews more working time; School is out, so families can more easily accommodate installation schedules; Immediate air conditioning efficiency improvements are noticeable on the first hot day after installation. We schedule summer installations early in the day when possible to minimize heat impact, and most Reston homes have central air conditioning that keeps interiors comfortable even with brief window openings during installation.

Winter Installation (December-February) is Perfectly Viable: Many homeowners assume winter is a poor time for window replacement, but Thompson Creek’s installation methods ensure quality results even in cold weather: Our installation process minimizes the time each window is open (typically 20-30 minutes); We work room by room so your home is never fully exposed; Modern sealants and expanding foams cure properly in cold temperatures; Your new windows immediately reduce drafts and cold spots that make winter uncomfortable. Winter is our slowest season, which means: Shorter lead times from ordering to installation (often 4-5 weeks vs. 6-8 weeks in busy seasons); More flexible scheduling (easier to accommodate your preferred dates); Potential seasonal promotions. Some of our most satisfied Reston customers scheduled winter installations and appreciated the immediate comfort improvements during the coldest months.

Order in Advance for Seasonal Transitions: If you want installation during a specific season, order accordingly: For spring installation (March-May), contact Thompson Creek in January-February; For fall installation (September-November), contact us in July-August; For summer or winter projects, we can often accommodate shorter lead times. This planning ensures you secure your preferred installation timeframe and allows our manufacturing facility adequate time to build your custom windows.

Consider Your Personal Schedule: The “best” time is often whenever fits your schedule. If you’re planning a summer vacation, consider installing windows before you leave (come home to improved comfort) or while you’re away (less disruption). If you work from home, winter might work well when you’re already inside. Teachers and school staff might prefer summer when schedules are more flexible. We’ll work around your schedule regardless of season to minimize disruption and maximize convenience.
