Maintenance
Inspect Window Seals
Window seal inspection turns vague comfort complaints into visible evidence: fogging, drafts, caulk gaps, water stains, and frame movement.
Average lifespan
20-35 years for many modern windows.
Typical repair range
$150-$800 per window for many repairs.
Typical replacement range
$500-$1,500+ per window installed.
Maintenance rhythm
Inspect annually and after severe weather or noticeable comfort changes.
Warning signs
- Fogging between panes
- Cracked caulk, gaps, drafts, or water stains
- Soft trim, swelling, peeling paint, or mold near windows
Recommended actions
- Photograph each window with symptoms and label by room.
- Clean tracks and weep paths so water can drain.
- Separate caulk/weatherstripping fixes from insulated-glass seal failure.
Planning notes
- One failed seal can be local; many failed seals from the same generation can become a replacement plan.
- Water intrusion should be handled quickly because trim and wall damage can spread.
- Drafts may also involve air sealing, insulation, or HVAC distribution.
FAQ
What does a failed window seal look like?
Fogging or moisture between panes is a common sign of insulated-glass seal failure.
Can I fix drafty windows without replacement?
Sometimes. Caulk, weatherstripping, hardware, and sash repairs may help if the frame and glass are still sound.
Why track window issues by room?
Room-level tracking shows whether issues are isolated or part of a broader exposure or age pattern.
