Condensation between panes in Talmadge, San Diego
Condensation or fog that forms between the two panes of glass, not on the interior or exterior surface, is a sign the insulated glass unit's seal has failed. This is different from ordinary condensation on the room-side surface of a window, which is a humidity issue, not a broken seal.
1900s-1930s stock, custom sizing and noise reduction.This is dense, older housing on small lots close to I-5, I-8, and busy arterial corridors, so street noise is as much a driver as temperature. Many original wood-sash windows from the 1900s-1930s are still in service, painted shut or warped out of square, alongside the single-pane aluminum that replaced some of them mid-century.
The gated blocks off Talmadge Drive and around the historic entry monuments hold larger homes where original steel-casement windows from the 1930s-40s are still in service on some houses, stiff and drafty at this age, and a full-frame vinyl or fiberglass swap is the common fix. Sitting a touch inland of the coastal buffer, Talmadge homes get real summer heat gain, which pushes owners toward Low-E glass on west-facing rooms.
What causes it
- Failed IGU seal letting humid air into the sealed cavity between panes
- Loss of the argon or krypton gas fill through the same seal failure
- Age: most IGU seals reach the end of their service life somewhere between 10 and 20 years
How it gets fixed
- IGU glass replacement when the frame and sash are sound
- Full window replacement when the frame is also compromised

Condensation between panes questions in Talmadge
Why does this happen in Talmadge?
Condensation or fog that forms between the two panes of glass, not on the interior or exterior surface, is a sign the insulated glass unit's seal has failed. This is different from ordinary condensation on the room-side surface of a window, which is a humidity issue, not a broken seal.. In Talmadge, the larger lots and established homes carry original steel-casement or early aluminum windows, so full-frame replacement and dual-pane upgrades lead the work here., which shapes how this shows up.
What is the difference between condensation on the glass and condensation between the panes?
Surface condensation (on the room-side glass) is a humidity and temperature issue that can be managed with ventilation or a warmer glass surface. Condensation between the panes means the sealed unit itself has failed and the glass needs to be replaced.
Can I dry out condensation between the panes?
No. The cavity is sealed and not accessible without replacing the glass unit. Any moisture inside will keep recurring because the seal that is supposed to keep it out has already failed.
Does condensation between panes mean I lost the argon fill too?
Almost always, yes. The same seal failure that lets humid air in also lets the insulating gas fill escape, so the window has lost both its clarity and part of its thermal performance.
