Fog or moisture between two glass panes means the window's insulated seal has failed. San Diego Window Repairs replaces failed double-pane glass units with proper low-E and argon options, restoring clarity and insulation without replacing the whole window.
What failed — the seal, not the glass
A double-pane window has a sealed air gap between the panes. When the seal fails, moisture enters and condenses inside. You cannot wipe it away because the fog is trapped between the two glass surfaces.
The correct fix: IGU replacement
The sealed insulated glass unit is replaced as one piece. We remove the old unit, measure precisely, and install a new sealed IGU that restores clarity, insulation, and warranty coverage.
Coastal seal failure
Salt air and ocean fog accelerate seal failure in La Jolla, Point Loma, and Pacific Beach homes. Early replacement prevents moisture from reaching the frame and turning a glass repair into a frame rebuild.
What double-pane repair costs
Standard IGU replacement runs $150–$450 per unit depending on size and glass type. Low-E or large units run $260–$520. Full window replacement is only needed when the frame has failed too.

Frequently asked questions
Can foggy double-pane windows be repaired?
Yes, by replacing the sealed insulated glass unit. Surface cleaning cannot remove fog trapped between the panes.
Do I need to replace the whole window?
No, unless the frame is damaged. Most homeowners only need the glass unit swapped while keeping the existing sash and trim.
How long does a new IGU last?
A quality sealed unit typically lasts 10–20 years in San Diego, with coastal exposure on the shorter end.
