By Window Type (Installed):

• Double-Hung Windows: $600-$1,200 per window
• Casement Windows: $700-$1,400 per window
• Picture Windows: $650-$1,300 per window

These ranges reflect quality vinyl replacement windows professionally installed with premium features like Low-E glass, argon gas fills, and advanced weatherstripping. Your actual cost depends on several factors specific to your Herndon home.

Factors Affecting Your Window Replacement Cost

Several elements influence the final investment for your Herndon window project:

Window Size & Configuration: Larger windows and specialty shapes cost more than standard sizes. Custom dimensions for older homes may require additional manufacturing time and expense.

Glass Options: Basic dual-pane windows cost less than triple-pane or specialty Low-E glass with advanced coatings. However, premium glass options deliver significantly better energy performance in Northern Virginia’s climate.

Frame Material: Vinyl windows offer the best value and performance for most Herndon homes. Wood-clad options provide traditional aesthetics for historic properties but cost 30-50% more.

Installation Complexity: Second-story windows, difficult access, or structural repairs increase labor costs. Older Herndon homes with settling or rot damage may need additional prep work.

Energy Efficiency Features: Energy Star certified windows with advanced features cost more upfront but deliver substantial utility savings over their lifetime—particularly important given NoVA’s temperature extremes.

Financing Options to Make Your Project Affordable

Thompson Creek believes every Herndon homeowner deserves beautiful, energy-efficient windows regardless of budget constraints. That’s why we offer flexible financing options with approved credit, including:

• Low monthly payments that fit your budget
• Competitive interest rates
• Quick approval process
• No prepayment penalties
• Seasonal promotional financing

Our goal is to make window replacement genuinely affordable without compromising on quality. During your free consultation, we’ll discuss financing options and help you find a payment plan that works for your financial situation.

Our Window Styles for Herndon Homes

Thompson Creek offers a comprehensive selection of replacement window styles to complement any Herndon home’s architecture and your functional needs.

Double-Hung Windows

Double-hung windows remain the most popular choice for Herndon homes, and for good reason. Both upper and lower sashes tilt in for easy cleaning—a crucial feature for second-story windows. The classic styling complements traditional Colonial, Cape Cod, and Craftsman homes throughout Herndon neighborhoods. Our double-hung windows feature spring-assisted balance systems for smooth operation, fusion-welded corners for strength, and multi-point locking systems for security. They provide excellent ventilation control and energy efficiency while maintaining the architectural character Herndon homeowners value.

Casement Windows

Casement windows hinge on the side and swing outward, offering unobstructed views and exceptional ventilation. They’re ideal for Herndon kitchens, bathrooms, and hard-to-reach locations above countertops or sinks. The crank mechanism makes them easy to operate even in high installations, and their compression seal design provides superior energy efficiency—no sliding sashes means no air leakage paths. Casement windows are particularly effective at catching cross-breezes during pleasant spring and fall weather, reducing your reliance on air conditioning.

Bay & Bow Windows

Bay and bow windows create dramatic focal points while adding valuable square footage to your Herndon home. Bay windows typically feature a large central picture window flanked by two smaller casement or double-hung units, projecting outward to create a cozy window seat area. Bow windows use four or more windows in a gentle curve for an elegant, expansive look. Both styles flood rooms with natural light, provide expansive views, and increase your home’s curb appeal and resale value. They’re particularly popular in Herndon living rooms and primary bedrooms.

Picture Windows

Picture windows are fixed units that don’t open, designed to frame beautiful views like large works of art. They’re perfect for showcasing your Herndon property’s landscaping or capturing natural light in living rooms and great rooms. Because they don’t open, picture windows offer maximum glass area, excellent energy efficiency (no moving parts means better seals), and unbeatable value. Many Herndon homeowners pair picture windows with flanking casement or double-hung units to balance views with ventilation.

Sliding Windows

Sliding windows glide horizontally on smooth tracks, making them ideal for Herndon homes where vertical space is limited or for installations over countertops, sinks, or bathtubs. They require minimal clearance to operate, making them practical for tight spaces. Modern sliding windows feature advanced roller systems for effortless operation and weatherstripping that maintains excellent energy efficiency. They’re popular in contemporary Herndon homes and work particularly well in bedrooms and hallways.

Awning Windows

Awning windows hinge at the top and open outward from the bottom, creating a protective awning effect that allows ventilation even during light rain. They’re excellent for Herndon’s unpredictable weather patterns, particularly during spring and summer when afternoon showers are common. Awning windows work beautifully in bathrooms for privacy and ventilation, and they’re often installed above or below fixed picture windows to add ventilation without compromising views. The outward-opening design also provides enhanced security compared to sliding styles.

Garden Windows

Garden windows project outward from your home like miniature greenhouses, featuring glass sides and a glass top to maximize sunlight. They’re perfect for Herndon homeowners who love cooking with fresh herbs or displaying plants, collectibles, or decorative items. The extended interior shelf space creates an attractive focal point in kitchens while providing excellent natural light for food preparation. Garden windows combine functionality with charm, adding character to any Herndon home.

Hopper Windows

Hopper windows are hinged at the bottom and tilt inward from the top, making them ideal for basement installations in Herndon homes. They provide secure ventilation for below-grade spaces while preventing intruders from entering. The inward-opening design keeps the exterior hardware protected from weather, and the sloped sill naturally sheds water away from your foundation. Many Herndon homeowners choose hopper windows for utility rooms, basements, and bathrooms where space is at a premium.

Energy Efficiency & Savings in Northern Virginia

Herndon homeowners face significant heating and cooling challenges due to Northern Virginia’s climate extremes—hot, humid summers often exceed 90°F while winter temperatures regularly drop below freezing. Old, inefficient windows are the #1 source of energy loss in most homes, accounting for up to 30% of heating and cooling costs.

Thompson Creek’s Energy Star certified replacement windows are specifically designed for the Mid-Atlantic climate zone, featuring:

Low-E Glass Coatings: Microscopic metallic layers reflect heat back into your home during winter and block solar heat gain during summer, reducing strain on your HVAC system year-round.

Argon Gas Fills: The space between dual-pane glass is filled with argon gas—denser than air and more effective at preventing heat transfer.

Advanced Weatherstripping: Multiple seals at all opening points eliminate drafts and air infiltration that waste energy and compromise comfort.

Insulated Frames: Multi-chamber vinyl frame construction provides superior thermal performance compared to older aluminum or hollow vinyl windows.

Average Annual Savings: Herndon homeowners typically save $200-$500 per year on utility bills after replacing single-pane or older windows with modern, energy-efficient models. Over the lifetime of your windows, these savings can exceed $10,000 while simultaneously improving your home’s comfort and indoor air quality.

Environmental Impact: Reducing your energy consumption also reduces your carbon footprint. Energy-efficient windows help Fairfax County meet sustainability goals while lowering your household’s environmental impact.

Our Window Replacement Process

Thompson Creek’s systematic approach ensures your Herndon window replacement project proceeds smoothly from initial consultation to final walkthrough.

Step 1: Free In-Home Consultation & Estimate

Your project begins with a no-pressure consultation at your Herndon home. Our window specialist will:

• Assess your existing windows and identify issues
• Discuss your goals, preferences, and budget
• Take precise measurements for accurate manufacturing
• Explain window options and energy efficiency features
• Provide a detailed written estimate with transparent pricing

There’s no obligation, no high-pressure sales tactics—just honest information to help you make an informed decision.

Step 2: Custom Manufacturing

Once you approve the project, we begin manufacturing your windows at our factory to your exact specifications. Custom manufacturing typically takes 4-6 weeks, during which time we’ll keep you informed of progress and schedule your installation date. Every window is built specifically for your Herndon home’s openings—no forcing ill-fitting stock windows into place.

Step 3: Professional Installation

Our experienced installation crews arrive on schedule, prepared to complete your project with minimal disruption to your daily routine. The installation process includes:

• Protecting your home’s interior with drop cloths
• Carefully removing old windows
• Inspecting and preparing rough openings
• Installing new windows with proper sealing and insulation
• Trimming and finishing interior and exterior
• Thorough cleanup—you won’t find a single nail or debris scrap

Most window replacements are completed in 1-3 days depending on project size. We work efficiently while maintaining the high quality standards Thompson Creek is known for throughout Northern Virginia.

Step 4: Final Inspection & Walkthrough

Before we consider your project complete, we conduct a thorough inspection with you to ensure every detail meets your expectations. We’ll demonstrate proper window operation, care, and maintenance. You’ll receive all warranty documentation and maintenance guidelines for your records.

Step 5: Follow-Up & Warranty Support

Your relationship with Thompson Creek doesn’t end at installation. We’re here for the lifetime of your windows with comprehensive warranty support. If you ever have questions or concerns, our customer service team is just a phone call away. This long-term commitment to customer satisfaction is what sets Thompson Creek apart from contractors who disappear after collecting payment.

Signs You Need Window Replacement in Herndon

Not sure if your Herndon home needs new windows? Watch for these telltale signs:

Difficulty Operating: Windows that stick, bind, or require force to open and close indicate hardware failure or frame warping. This isn’t just inconvenient—it’s a safety issue during emergencies.

Drafts & Air Leaks: If you feel cold air near windows during winter or hot air during summer, failing seals are wasting your money on heating and cooling costs.

Condensation Between Panes: Foggy glass or moisture between dual-pane windows means the seal has failed and insulating gas has escaped. This dramatically reduces energy efficiency and can’t be repaired—only replaced.

Rising Energy Bills: Unexplained increases in utility costs often trace back to inefficient windows that force your HVAC system to work harder maintaining comfortable temperatures.

Visible Damage: Cracked glass, rotting wood frames, peeling paint, or deteriorating caulking aren’t just cosmetic issues—they indicate structural problems that will worsen over time.

Outside Noise: If you hear traffic, neighbors, or lawn equipment clearly through closed windows, poor sound insulation is affecting your quality of life.

Fading Furniture & Flooring: UV damage to interior furnishings indicates your windows lack protective Low-E coatings that modern windows provide.

Age Over 20 Years: Even well-maintained windows lose efficiency over time. If your windows are 20+ years old, replacement will deliver significant energy savings and performance improvements.

Repair vs Replace: Making the Right Choice

Minor issues like broken hardware or damaged weatherstripping can often be repaired cost-effectively. However, replacement is usually the better investment when:

• Multiple windows show problems
• Frames are damaged or deteriorating
• Windows are more than 15-20 years old
• Energy efficiency is poor
• You’re planning to sell your home within a few years

Thompson Creek’s window specialists provide honest assessments—if repair makes sense, we’ll tell you. But when replacement is the smarter choice, we’ll explain why and provide options that fit your budget.

Customer Testimonials

Sarah M. – Herndon Town Center

“We live in a 1960s Colonial near Town Center, and our original windows were costing us a fortune in heating bills. Thompson Creek’s team was professional from start to finish—they helped us choose double-hung windows that matched our home’s traditional style while dramatically improving energy efficiency. The installation took just two days, and our winter heating bill dropped by nearly $80 per month. Five years later, the windows still look and operate like new. Worth every penny!”

James & Linda K. – Floris

“After getting quotes from three different companies, Thompson Creek offered the best combination of quality and value. We appreciated their transparent pricing—no games, no pressure, just honest information. They replaced 18 windows in our Floris home, and the difference in comfort is remarkable. No more drafts, no more condensation, and our home is so much quieter now. The lifetime warranty gave us peace of mind, and their financing option made the project affordable without straining our retirement budget.”

Michael T. – McNair

“I’m pretty handy and considered DIY window replacement to save money, but I’m so glad I hired Thompson Creek instead. Their installers showed up exactly on time, protected everything with drop cloths, and worked incredibly efficiently. They finished all 12 windows in a single day, and the quality is outstanding. The windows are custom-built specifically for my home’s openings—no forcing stock sizes like big-box stores do. The insulation and weatherproofing is perfect, and they left my house cleaner than they found it. You can’t put a price on that level of professionalism and craftsmanship.”

Thompson Creek vs Big Box Stores

Many Herndon homeowners consider big-box retailers for window replacement to save money, but the apparent savings often disappear when you account for the full picture:

Manufacturing Quality: Thompson Creek manufactures our own windows to exacting standards with premium components. Big-box windows are mass-produced to meet price points, often sacrificing quality for affordability.

Installation Expertise: Our installers are experienced Thompson Creek employees who’ve completed thousands of Northern Virginia projects. Big-box stores subcontract to whoever’s available, with wildly inconsistent skill levels and accountability.

Warranty & Accountability: Thompson Creek’s lifetime warranty covers both materials and installation—one company stands behind everything. Big-box warranties typically exclude installation, and tracking down accountability when problems arise becomes your headache, not theirs.

Custom vs Stock: We custom-manufacture every window for your specific openings. Big-box stores offer limited stock sizes that installers force to fit, compromising performance and longevity.

Long-Term Value: Quality materials and expert installation mean Thompson Creek windows last longer, perform better, and deliver superior energy savings over their lifetime—more than offsetting any initial price difference.

Local Expertise: We understand Northern Virginia’s building codes, architectural styles, and climate challenges. National big-box stores follow one-size-fits-all approaches that don’t account for regional specifics.

The bottom line? Thompson Creek delivers better windows, better installation, better warranty, and better long-term value—making us the smarter investment for your Herndon home.
