Glass damaged

Double pane windows require an airtight seal in order to function correctly. The most typical indication that a seal is failing is the formation of condensation between the glass plates. Condensation that forms between glass plates is not a major problem and can be fixed however, it's an indication that your glass unit needs replacing. If you have an older double-glazed window, this could require replacing both the glass and the frame. If your frame is in good condition, you may be able to save money by simply replacing the glass.

Glass is fragile and it's not uncommon for double-pane windows that develop cracks over time. If the cracks were not caused by mechanical damage or a sudden impact on the window they can be fixed with epoxy and elbow grease. Follow the manufacturer's instructions and clean the cracked area by using a damp cotton cloth. Then apply the epoxy to the crack. Allow the epoxy to fully dry before sanding down and painting over the repaired area.

It's also possible to keep cracks from spreading with a simple strip of masking tape. One strip of tape on both sides of the cracked area is enough to prevent superficial cracks, like stress cracks that result from low temperatures, from escalating. If you notice more severe cracks in your glass that are already present, it's recommended to consult an expert for repair.

This is generally a good thing during winter because it prevents heat loss.

If your windows appear cloudy and have a film of water on them, you must contact an experienced professional glazier. This is an indication that the 'air gap' seal between the two panes of glass is beginning to break down and allowing moisture into the window.

Alternatively, there are several professional companies that can help repair condensation build-up in double-glazed windows by drilling holes into the window and then injecting or pumping a special desiccant to eliminate the excess moisture. This is a more complicated procedure that requires the unit to be removed from the frame, opening up each glass pane to clean them thoroughly, then filling them with desiccant prior to sealing them up.
