How to Extend the Life of Your Windows: Essential Maintenance Tips
November 20, 2024
Your windows are a major investment. With proper care, quality windows should last 15-20 years or more. Here's how to make sure yours do.
Spring Window Maintenance (April-May)
After a harsh Rochester winter, your windows need attention.
1. Deep Clean Inside and Out
What you need:
- Mild dish soap and warm water
- Microfiber cloths
- Squeegee
- Vacuum with brush attachment
How to do it:
- Vacuum tracks and sills to remove dirt and debris
- Wash glass with soapy water, rinse, squeegee
- Clean frames with appropriate cleaner (vinyl, wood, or aluminum)
- Don't use abrasive cleaners that can damage surfaces
Pro tip: Clean windows on a cloudy day to prevent streaking from quick drying.
2. Inspect Weatherstripping
Look for:
- Cracks or tears in the weatherstripping
- Gaps when window is closed
- Hard, brittle material (should be flexible)
If damaged: Replace immediately. Weatherstripping costs $2-5 per window but saves hundreds in energy costs.
3. Check and Replace Caulking
Inspect the exterior caulk around:
- Where the window frame meets the siding
- Corner joints
- Where trim meets the frame
Look for:
- Cracks or gaps
- Missing sections
- Peeling or separation
To replace:
- Remove old, damaged caulk completely
- Clean surface thoroughly
- Apply new exterior-grade caulk
- Smooth with a wet finger or tool
4. Lubricate Moving Parts
Apply lubricant to:
- Sliding tracks (use silicone spray)
- Hinges on casement windows
- Locking mechanisms
- Crank operators
Don't use: WD-40 (attracts dirt), oil-based products on vinyl
Summer Maintenance (June-August)
Light maintenance while enjoying the nice weather.
1. Test Window Operation
- Open and close each window
- Check that locks engage properly
- Ensure screens fit snugly
- Verify that windows stay open when raised
2. Clean and Repair Screens
Process:
- Remove screens
- Wash with mild soap and water
- Check for tears or holes
- Repair small tears with screen patch kit
- Replace severely damaged screens
3. Touch Up Paint (Wood Windows)
Rochester summers are the perfect time for exterior painting:
- Scrape any peeling paint
- Sand smooth
- Prime bare wood
- Apply exterior paint (2 coats)
- Paint in temperatures above 50°F
4. Clear Weep Holes
Those small holes at the bottom of window frames aren't defects—they drain water!
- Use a thin wire or pipe cleaner
- Gently clear any blockages
- Ensure water can drain freely
Fall Preparation (September-October)
Get ready for winter before the cold hits.
1. Inspect for Air Leaks
The candle test:
- Light a candle
- Hold near window edges on a windy day
- Watch for flickering = air leak
Fix leaks by:
- Adding/replacing weatherstripping
- Re-caulking gaps
- Adjusting window sashes
2. Clean Tracks Thoroughly
Debris in tracks prevents proper closing = winter drafts
- Vacuum first
- Scrub with old toothbrush
- Wipe clean and dry
- Apply silicone spray
3. Check Drainage
Test exterior drainage:
- Pour water along the sill
- Watch it drain through weep holes
- Clear any blockages
Why it matters: Ice buildup from poor drainage can damage windows all winter.
4. Consider Storm Windows
For older windows:
- Add interior or exterior storm windows
- Significantly improves insulation
- Removable for summer
Winter Care (November-March)
1. Manage Condensation
Causes:
- High indoor humidity
- Poor air circulation
- Single-pane windows
Solutions:
- Use exhaust fans when cooking/showering
- Run dehumidifier in winter
- Keep curtains open during day
- Wipe away condensation regularly
Why it matters: Persistent condensation leads to mold and frame rot.
2. Remove Ice and Snow Carefully
Never:
- Use sharp objects to chip ice
- Force frozen windows open
- Use heat guns on vinyl windows
Do instead:
- Let ice melt naturally
- Use de-icing spray (safe for windows)
- Gently brush off snow
3. Monitor for Frost
Interior frost indicates:
- Failed seal
- Poor insulation
- High humidity
Address the root cause to prevent damage.

- ❌ Pressure wash windows directly
