We have a large (about 8" X 6") double pane picture window that has started to show condensation between the panes of glass. That space is also occupied by a grid of 14" X 14" squares. I'm guessing that the seal between the panes of glass has been broken. Can my problem be fixed? If so, who does this kind of work? Thanks.

There are companies that claim they can repair a bad seal but I have never used them. “Get the Fog Out” of Thermopane Windows at Home Ray Sands Glass Blog Most thermopane has a 25 year warranty so you may try to explore that. In most cases we just swap out the bad windows completely.
