Repair vs. Replace: How to Decide
Not sure if your windows need repair or replacement? Here's a general guide:
| Problem | Usually Repairable | May Need Replacement |
|---|---|---|
| Foggy/cloudy glass | ✓ Sealed unit replacement | If frame is rotted/damaged |
| Drafty windows | ✓ Weatherstripping replacement | If frame is warped |
| Window won't open/close | ✓ Hardware/operator repair | If frame is damaged |
| Broken glass | ✓ Glass replacement | If frame is compromised |
| Water leaking in | ✓ Resealing/caulking | If frame is rotted |
| Condensation inside | ✓ Sealed unit replacement | If multiple units failed |
| Wood rot | Minor rot can be repaired | Extensive rot = replace |
Save Thousands With Window Repair
The math is simple: window repair typically costs 50-80% less than full replacement.
- Sealed unit replacement: $150-350 vs. $500-1,500 for new window
- Hardware repair: $50-200 vs. $500+ for new window
- Weatherstripping: $100-300 vs. thousands for new windows
- Crank operator: $75-250 vs. $600+ for new casement
For a home with 10-15 windows showing seal failure, repair can save you $5,000-$15,000 compared to full replacement—while achieving the same results.

Common Questions About Window Repair
Most window problems are repairable if the frame is in good condition. Issues like foggy glass, broken hardware, failed weatherstripping, and stuck sashes are almost always repairable. We offer assessments to determine the best solution for your situation.
Many repairs can be completed in a single visit. Hardware repairs and weatherstripping typically take 30-60 minutes per window. Sealed unit replacements require two visits—one to measure and one to install (usually 1-2 weeks apart).
For most repairs, yes. A new sealed unit provides the same insulation and clarity as the original. New hardware functions identically to the original. The main advantage of full replacement is upgrading to better glass technology (triple-pane, better Low-E coatings).
Yes. We repair windows from all manufacturers including Pella, Andersen, Marvin, North Star, All Weather, and dozens more. Our extensive parts inventory means we can source hardware for virtually any window, even discontinued models.
