If your double-glazed windows begin to show signs of aging, you may be entitled for them to be replaced under warranty. Double-glazed window repairs require replacing the existing glass unit. The seal isn't working properly in the event that you see misting. Glass damaged A seal that is airtight is essential for double pane windows to function effectively. The most common indication that a seal is failing is the formation of condensation between the glass plates. While condensation between glass is not an issue that needs to be fixed, it's typically an indication that the glass unit is in need of replacement. If you have an older double-glazed window, this could require replacing both the frame and the glass. If your frame is in good shape, however, you can generally save money by replacing just the glass. Double-paned windows may develop cracks because of the fragility of glass. If the cracks weren't caused by mechanical damage or a sudden impact on the window, they can be repaired with epoxy and some elbow grease. Start 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 applying paint and sanding to the repaired area. A simple strip of masking tap can be used to keep a crack from spreading. One strip of tape on both sides of the damaged area is enough to prevent superficial cracks, like stress cracks that are caused by low temperatures, from escalating. However, if you're dealing more serious cracks that are already forming in your glass, it may be better to contact a professional to ensure the safety of the repair. It's risky and difficult to replace a single pane of double-paned windows. Double-paned windows are constructed as a whole unit and sealed with inert gases in the factory.

Additionally, there are specialist companies who will fix condensation build-up in double glazed windows by drilling holes in the window and then injecting or pumping a special desiccant in order to eliminate the excess moisture. This involves removal of the sealed unit from the frame and then cleaning each pane of the glass before refilling the desiccant. This is usually a more expensive solution, but it's important to check that the company you choose to work with is insured and is registered with FENSA.
