Fogged Window Repair vs. Full Window Replacement
Most Portland homeowners don't need to replace the entire window — just the glass unit. Here's how to know which option is right for you.
Replace Just the Glass (IGU) — $150–$400
Best option when:
- Frame is in good condition
- Window opens and closes properly
- No rot, warping, or damage to frame
- Window is less than 20 years old
- You want to save money
Full Window Replacement — $500–$1,200
Better option when:
- Frame is rotted, warped, or damaged
- Window is single-pane (no insulation)
- Window is 20+ years old
- Multiple windows need updating
- You want to upgrade to energy-efficient windows
Why Do Windows Fog Up in Portland?
Portland's climate is particularly hard on window seals. Our wet winters, temperature swings between seasons, and frequent rain create ideal conditions for seal failure. Here's what happens:
Seal Fails
The rubber seal around the insulated glass unit (IGU) degrades over time from UV exposure, temperature cycling, and moisture.
Moisture Enters
Once the seal fails, humid air from outside enters the space between the glass panes.
Condensation Forms
The moisture condenses on the inner glass surfaces, creating the foggy, cloudy, or streaky appearance you see.
Frequently Asked Questions
Why are my windows fogged or cloudy between the panes?
Fogging between window panes means the seal on your insulated glass unit (IGU) has failed. When the seal breaks, moist air enters the space between the panes and condenses, creating a foggy or cloudy appearance. This is a common problem in Portland due to our wet climate and temperature swings.
Can fogged windows be repaired, or do they need to be replaced?
In most cases, fogged windows require glass replacement rather than repair. The failed seal cannot be permanently re-sealed. However, you usually only need to replace the glass unit (IGU), not the entire window frame. This is significantly less expensive than full window replacement. We assess each window and recommend the most cost-effective solution.
How much does fogged window glass replacement cost in Portland?
