Double Glazed Window Repair Most double glazed windows come with a warranty, and it's worth examining what this covers. It typically covers any issues with window hardware, such as hinges and locking mechanisms, in the first 10 years. The mist that forms between the glass windows is often caused by a crack in the seal, and it's something that requires immediate repair to stop damp or mould developing in your property. Condensation Between the Windows If condensation develops between the windows in your home, it's an indication that the seal securing the gas that insulates between the panes has failed. This is a serious problem that must be dealt with immediately, particularly in winter, when humidity levels are at their highest. It could also cause damage to the sills or sealants and also cause mould. Double-glazed windows shouldn't be able to have condensation between the panes. This can be caused by high humidity or a very cold snap. Fortunately, it is repairable without having to replace the entire window. A professional can drill tiny holes in the glass and spray the inside of the window with a specific cleaning solution. The water is then removed from the window and an anti-fogger can be installed to stop the build-up of moisture in the future. Condensation can also happen between the windows as a result of air leakage, or other factors outside the window. In this case it could take longer for the condensation in the window to build up because the air must be warm enough to vaporise the water molecules. In these situations it is recommended to replace the double glazed windows rather than repair the existing sealed units. A double-glazed window is constructed consisting of two or three pieces of insulated glass, held together by a metal frame. The gap in the middle of the window is filled with a non-toxic insulating gas such as argon or krypton and then sealed tightly. The seal prevents the gas that is insulating from escape and also preventing air and moisture from entering through the gap. As windows age, the seals weaken and allow moisture to leak into the gap between the glass panes. It is important to recognise when seals are beginning to leak, as it means that the double glazing isn't functioning as well as it once was. This could result in lower energy efficiency, higher heating bills, damage to the properties and the risk of condensation between the windows. Mist If you have condensation on the outside of your windows, it is totally normal - it means that your double-glazed is functioning properly and retaining the heat inside your home. The condensation happens because the air outside is hotter than the glass, and reaches the dew point of the window earlier than the air inside. This is one of the major benefits of having good quality double glazing. If you notice condensation on the inside of your window, this could be a sign of a ventilation issue within your home.
