Foggy Window Glass Repair in Knoxville, TN: Repair or Replace?
Why Windows Fog Up Between The Panes
If the fog is between the panes, not on the room side, the problem is usually a failed seal in an insulated glass unit. No amount of scrubbing fixes it because the moisture is sealed inside the unit.

When Glass Repair Makes Sense And When It Does Not
The right answer depends on whether the issue is only with the glass or with the full assembly. If the frame is straight, the sash operates smoothly, and the only failure is the sealed glass unit, repair is often the better value.

How To Decide Before You Spend The Money
