Glass damaged

Double pane windows require an airtight seal in order to perform effectively. 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 issue and can be corrected however it is an indication that your glass unit is in need of replacement. If you have an older double glazed window, double glazing this may require replacing both the frame and the glass.

Glass is brittle, and it's not uncommon for double-pane windows to develop cracks as time passes. If the cracks aren't caused by mechanical damage or a sudden impact, it's usually possible to repair these cracks with epoxy and a tiny amount of elbow grease. Begin by cleaning over the area that is cracked with a damp cotton rag and then apply epoxy to the crack following the manufacturer's instructions. Let the epoxy completely dry before painting and sanding the repaired area.

It's also possible to keep cracks from spreading with the use of a strip of masking tape. A single strip of tape on both sides of the cracked area is enough to stop superficial cracks, such as stress cracks that result from low temperatures, from escalating. If you notice deeper cracks in your glass that are already present, it is best to contact an expert to repair the damage.

Attempting to replace just a single pane of double-pane windows is a risky and difficult DIY task. Double-paned windows are constructed as a unit and sealed with inert gas in the factory.

You can stop this from happening by using a dehumidifier, improving ventilation or applying a de-icing agent. Alternatively, there are several professional companies that can help fix condensation build-up in double glazed windows by drilling holes in the window unit and pumping or injecting a specific desiccant to eliminate the excess moisture. This is a more complicated procedure that requires the sealed unit to be removed from the frame, and then opening each glass pane and thoroughly cleaning them, then filling them with desiccant prior to sealing up again. This is usually more expensive, however it is worth checking whether the firm you choose to use is insured and is registered with FENSA.
