Many homeowners are quick to clean smudges and streaks from glass, but protecting window and door frames is equally essential for long-term performance and value. Regular maintenance extends the life of your windows and doors, prevents costly repairs, and ensures your home stays energy-efficient year-round. Discover how to care for windows and doors properly, from choosing the right cleaners to controlling condensation and addressing common issues before they become expensive problems.

Why Window and Door Maintenance Matters

Your windows and doors represent a significant investment in your home’s comfort, energy efficiency, and curb appeal. Thompson Creek’s 50-year No-Hassle Warranty covers materials and professional installation, but proper maintenance helps ensure your windows and doors deliver peak performance throughout their expected lifespan.

Benefits of Regular Maintenance:

  • Extended lifespan of windows and doors (30+ years with proper care)
  • Maintained energy efficiency preventing utility bill increases
  • Preserved appearance and curb appeal
  • Early problem detection before minor issues become major repairs
  • Warranty compliance meeting manufacturer requirements
  • Higher resale value when properly maintained

The good news? Windows and doors from quality manufacturers like Thompson Creek require minimal maintenance compared to older designs. Modern materials like vinyl and fiberglass resist rot, warping, and fading, while advanced weatherstripping and hardware need only occasional attention.

How to Care for Windows Made from Traditional Materials

Windows are easy to maintain, but they’re also easy to damage if you don’t care for them correctly. Clean your windows regularly following the schedule recommended by your manufacturer or installer. For most homes, seasonal deep cleaning (four times per year) plus spot cleaning as needed keeps windows looking great and performing optimally.

We’ve broken down common window cleaning and maintenance tasks by component:

Glass Cleaning and Care

Wipe down interior and exterior glass as often as needed to maintain clarity and appearance. While glass cleaner is safe for some windows, that’s not always the case, especially for specialized coatings.

Safe Cleaning Approach: When in doubt, use mild dish soap and water to clean your window’s interior and exterior glass. This gentle solution effectively removes dirt, pollen, fingerprints, and other residue without risking damage to coatings or finishes.

Tools to Use: Clean glass with a soft cloth or microfiber towel, never an abrasive brush or sponge that might scratch the surface. Paper towels can leave lint and residue, so avoid them for final polishing.

Technique:

  1. Mix a few drops of mild dish soap in warm water
  2. Dampen your cloth (don’t oversaturate)
  3. Wipe glass in circular motions or side-to-side strokes
  4. Rinse with clean water
  5. Dry immediately with a clean, lint-free cloth
  6. Buff to a streak-free shine

Frequency:

  • Exterior glass: Clean seasonally (spring and fall minimum)
  • Interior glass: Clean as needed when smudges or film appear
  • High-traffic areas: May need monthly attention

For detailed cleaning techniques and seasonal tips, review our guide on how to clean windows and screens effectively.

Frame Maintenance

Carefully vacuum around the frames and tracks of your windows before wiping them down. This preliminary step removes loose dirt, pollen, dead insects, and debris that might scratch surfaces during wet cleaning.

Cleaning Process: As with glass, frames are best cleaned with water and mild dish soap. Harsh cleansers can cause your frames to crack, discolor, or eat away at factory finishes and paint. Never use abrasive cleaners, petroleum-based solvents, or products containing ammonia on vinyl or fiberglass frames.

Frame-Specific Care:

Vinyl Frames:

  • Wipe down with soap and water solution
  • Rinse thoroughly to prevent soap residue buildup
  • Avoid harsh chemicals that can cause yellowing or brittleness
  • Never paint vinyl frames (use factory color options instead)

Fiberglass Frames:

  • Clean with mild soap and water
  • Can be painted if you want to change colors
  • More scratch-resistant than vinyl
  • Check for any sealant degradation annually

Wood Frames:

  • Inspect annually for moisture damage, rot, or peeling finish
  • Touch up paint or stain as needed to prevent water intrusion
  • Check caulking around exterior frames
  • Consider professional refinishing every 5 to 7 years

Aluminum Frames:

  • Clean with soap and water
  • Check for corrosion, especially in coastal areas
  • Touch up scratched or chipped paint promptly
  • Lubricate moving parts annually

Track and Sill Cleaning: Tracks and sills collect the most debris. Use a vacuum with a brush attachment, then wipe with a damp cloth. For stubborn dirt in track corners, use an old toothbrush or cotton swab. Keep tracks clear to ensure smooth window operation and proper drainage.

Screen Care and Maintenance

Take out your window screens slowly, taking care not to bend or rip them during removal. Most screens have small tabs or clips that release them, but forcing or pulling too hard can damage frames or tear mesh.

Cleaning Process:

  1. Lay each screen flat on a clean surface (driveway, patio, or large tarp)
  2. Use a soft brush to gently scrub away pollen, dirt, and other residue
  3. You can also use a mixture of mild dish soap and water as you clean
  4. Rinse your screen thoroughly with a garden hose on gentle spray
  5. Gently pat dry with a lint-free cloth
  6. Allow screens to air-dry completely before reinstalling

Don’t Use:

  • Paper towels (leave residue and lint)
  • High-pressure washers (can tear mesh or damage frames)
  • Harsh chemicals (can degrade mesh material)
  • Stiff brushes (can tear or stretch mesh)

Screen Inspection: While cleaning, check for:

  • Tears or holes in mesh
  • Bent or damaged frames
  • Missing or damaged clips
  • Loose mesh that’s pulled away from frame

Small tears can be temporarily patched with clear nail polish or screen repair kits available at hardware stores. Larger damage typically requires screen replacement, which Thompson Creek can handle as part of our ongoing service commitment.

Condensation Control and Prevention

Condensation is a common complaint, but minor amounts won’t damage your glass or affect window performance. However, excessive condensation can indicate ventilation problems, humidity issues or in rare cases, seal failure in insulated glass units.

Understanding Condensation: Condensation forms when warm, moist air contacts a cooler surface. Interior condensation on glass is usually environmental (caused by indoor humidity), while condensation between panes indicates seal failure requiring professional attention.

Ways to Reduce Interior Condensation:

  • Run exhaust fans in bathrooms during and after showers (minimum 20 minutes)
  • Use a dehumidifier in basements or humid areas (target 30 to 50% relative humidity)
  • Open doors and windows when possible to allow air circulation
  • Position dryer vents outside and ensure they’re not blocked
  • Vent cooking activities by using range hoods during meal preparation
  • Avoid overwatering houseplants which release moisture into the air
  • Run ceiling fans to circulate air and prevent condensation-prone cold spots
  • Maintain consistent temperatures rather than large temperature swings

These tips help ensure excess moisture ends up outside rather than collecting on your windows.

When to Worry:

  • Condensation between glass panes (seal failure)
  • Ice forming on interior glass in winter (severe air leakage)
  • Persistent condensation despite humidity control
  • Water pooling on sills or frames
  • Mold or mildew growth around windows

If you notice these issues, professional evaluation is recommended. Learn more about identifying and solving common window problems before they require expensive repairs.

How to Care for Windows with Insulated or Low-E Glass

Windows made from insulated glass or covered with Low-E (low-emissivity) or heat-deterrent coatings require special care. You can often clean the screens and frames the same way you clean traditional windows, but be careful with the glass itself. The wrong cleaner or even residue from the right one may damage your insulated window’s delicate coatings.

Understanding Low-E and Insulated Glass

Low-E coatings are microscopically thin metallic layers applied to glass that reflect infrared light (heat) while allowing visible light to pass through. These coatings dramatically improve energy efficiency but can be damaged by harsh chemicals, abrasive cleaning, or improper techniques.

Insulated glass units (IGUs) consist of two or more panes with sealed air spaces between them. The sealed edges contain desiccants to absorb moisture and maintain clarity. Damage to these seals leads to condensation between panes and loss of insulating value.

Care Guidelines for Specialized Glass

Here are specific tips to help you remember how to care for windows with insulated glass or heat-deterrent coatings:

DO:

  • Clean glass with water mixed with mild dish soap
  • Wipe down frames and glass gently with soft cloths
  • Clean windows on cloudy days, early mornings, or evenings
  • Use soft microfiber cloths designed for glass
  • Rinse thoroughly to remove all soap residue
  • Dry immediately to prevent water spots
  • Test cleaning solutions on a small area first

DON’T:

  • Use petroleum-based solvents or harsh chemicals on glass
  • Apply pressure cleaners or high-pressure spray
  • Clean windows under direct sunlight (causes streaking and rapid drying)
  • Use abrasive scouring pads or sharp tools
  • Spray cleaner directly onto glass (spray cloth instead)
  • Allow cleaning solution to dry on glass surface
  • Use razor blades or metal scrapers

Products to Avoid on Low-E Glass:

  • Ammonia-based cleaners
  • Vinegar solutions (acidic, can damage coatings)
  • Abrasive powders or creams
  • Strong alkaline cleaners
  • Solvent-based products
  • Steel wool or abrasive pads

Be careful from start to finish when cleaning Low-E or insulated windows, as one wrong move can permanently damage the delicate glass coating, resulting in a hazy appearance that cannot be corrected without glass replacement.

Professional Tip: If you’re unsure about your window’s coating, contact Thompson Creek for specific care recommendations. We keep detailed records of the glass packages installed in your home and can provide manufacturer-approved cleaning guidance.

How to Care for Doors

Customers often ask how to care for doors, especially entry doors with glass panels, patio sliding doors, and storm doors. You can clean and maintain many door parts on your own, but you may benefit from professional assistance for some labor-intensive tasks or specialized components.

General Door Cleaning

Like windows, many door parts are best cleaned with a mixture of water and mild dish soap. You can use this mixture to wipe down:

  • Exterior glass panels and sidelights
  • Interior glass surfaces
  • Screen doors and mesh panels
  • Door tracks and thresholds
  • Weatherstripping and seals

Make sure to use a soft cloth or brush rather than abrasive pads or paper towels.

Door-Specific Maintenance Tasks

Entry Doors:

Fiberglass Doors:

  • Clean with mild soap and water
  • Touch up scratches with manufacturer’s touch-up kit
  • Can be repainted if desired (use exterior-grade paint)
  • Check weatherstripping annually for wear
  • Inspect door sweep at bottom for damage

Steel Doors:

  • Wipe down regularly to remove salt and moisture
  • Touch up any chips or scratches immediately to prevent rust
  • Check for dents or damage
  • Lubricate hinges annually

Wood Doors:

  • Refinish every 3 to 5 years (more often in harsh sun exposure)
  • Check for warping, cracking, or moisture damage
  • Maintain paint or stain to prevent water intrusion
  • Consider adding storm door for additional protection

For comprehensive information on door materials and their maintenance requirements, explore the benefits of fiberglass versus wood doors.

Patio Doors:

Sliding patio doors require attention to tracks and rollers for smooth operation:

  1. Track Cleaning: Vacuum tracks thoroughly, then wipe with damp cloth. Use old toothbrush for corners.

  2. Roller Lubrication: Lubricate moving parts, including tracks and rollers, with silicone spray lubricant (not oil-based products that attract dirt). Apply sparingly every 6 months or when operation becomes difficult.

  3. Roller Adjustment: You may need to adjust door rollers if your door sticks or doesn’t close correctly. Most patio doors have adjustment screws at the bottom corners. Turn clockwise to raise the door and counterclockwise to lower it.

  4. Lock Strike Plate: The lock strike plate may also require adjustment if you move the rollers, so watch for alignment issues. The door should latch securely without forcing.

  5. Weatherstripping Check: Inspect weatherstripping on the stationary panel and around the door frame. Replace if compressed, cracked, or no longer seals properly.

Storm Doors:

Storm doors protect your entry door while allowing ventilation:

  • Clean glass or screen panels seasonally
  • Switch between glass and screen inserts as seasons change
  • Check pneumatic closers (adjust speed if needed)
  • Lubricate hinges and latches annually
  • Inspect weatherstripping and replace if worn
  • Ensure proper alignment (door shouldn’t scrape frame)

Hardware Maintenance

Door hardware requires periodic attention to maintain smooth operation and security:

Hinges:

  • Tighten loose screws (check every 6 months)
  • Lubricate with silicone spray or light machine oil annually
  • Replace if bent, damaged, or showing signs of rust

Locks and Deadbolts:

  • Lubricate keyholes with graphite powder (never oil)
  • Test operation regularly
  • Tighten mounting screws
  • Replace if sticking or difficult to operate

Door Handles and Levers:

  • Tighten set screws underneath handle
  • Clean regularly to remove dirt and grime
  • Lubricate internal mechanisms annually
  • Replace if loose or worn

Automatic Door Closers:

  • Adjust closing speed if too fast or slow
  • Tighten mounting screws
  • Replace if leaking hydraulic fluid

Frequently Asked Questions About Window and Door Care

How often should I clean my windows?

Clean exterior windows at least twice per year (spring and fall), with spot cleaning as needed. Interior windows can be cleaned quarterly or as needed when smudges and film appear. High-traffic areas or homes with children may require more frequent attention. Coastal homes exposed to salt air should clean windows more frequently to prevent corrosion and film buildup.

Can I use vinegar to clean windows?

While vinegar is often recommended, avoid it on Low-E coated glass or tinted windows. The acidic nature can damage specialized coatings over time. For standard glass, a 50/50 vinegar and water solution works, but mild dish soap and water is safer for all window types and equally effective. When in doubt, stick with the gentle approach.

What causes condensation between window panes?

Condensation between panes indicates seal failure in the insulated glass unit. The desiccant that absorbs moisture has become saturated, or the seal has developed a breach allowing humid air inside. This cannot be fixed by cleaning and requires glass unit replacement. Contact Thompson Creek if your windows show this issue, as it’s typically covered under warranty if within the coverage period.

How do I know if my weatherstripping needs replacement?

Check weatherstripping by:

  • Running your hand around closed windows and doors to feel for drafts
  • Holding a lit incense stick near seams (smoke will move if air is leaking)
  • Looking for compressed, cracked, or torn weatherstripping
  • Checking if material has lost its flexibility

Replace weatherstripping when you notice any of these signs. New weatherstripping is inexpensive and can significantly improve energy efficiency.

Why won’t my patio door slide smoothly?

Common causes include:

  • Dirty tracks (clean thoroughly)
  • Dry or corroded rollers (lubricate with silicone spray)
  • Misaligned rollers (adjust with screws at door bottom)
  • Damaged rollers (may need replacement)
  • Bent or damaged track
  • Debris caught under door

Start with cleaning and lubrication. If problems persist after adjustment, professional service may be needed.

Can I pressure wash my windows and doors?

Never use pressure washers on windows or doors. High-pressure water can:

  • Force water past weatherstripping and seals
  • Damage Low-E coatings
  • Break glass seals in insulated units
  • Damage caulking and sealants
  • Force water into wall cavities

Use a garden hose on a gentle spray setting instead, or hand-wash for best results.

What’s the white film on my windows?

White, cloudy film on glass is typically mineral deposits from hard water (exterior) or condensation that’s dried repeatedly (interior). Remove with:

  • White vinegar solution (if no Low-E coating)
  • Commercial mineral deposit removers
  • Fine steel wool (000 grade, very gentle, standard glass only)
  • Professional cleaning if DIY methods fail

For Low-E glass, test any solution on a small area first or consult Thompson Creek for recommendations.

Should I remove screens in winter?

This depends on your climate and window type:

Remove screens if:

  • You don’t open windows in winter
  • Screens show damage needing repair
  • You want maximum light transmission
  • Heavy snow or ice might damage screens

Leave screens installed if:

  • You occasionally open windows for ventilation
  • Removing and reinstalling is difficult
  • Screens are in good condition
  • Storage space is limited

Clean screens before winter regardless of whether you remove them.
