How to Repair Double Glazed Windows
Double glazing is typically covered by a warranty for 10 or 20 year. So, if your double glazed windows are showing signs of ageing you may be entitled to have them fixed under warranty.
Double-glazed window repair involves the re-sealing of your glass unit. The seal is failing if you see mist.
Glass damaged
A seal that is airtight is essential for double pane windows to work effectively. The condensation between the glass plates is a common sign of a failing seal. While condensation between glass isn't a serious problem and can be dealt with, it's typically a sign that the glazing unit needs to be replaced. If you have an older double-glazed window, this may mean replacing both the frame and the glass. If your frame is in good shape, however, you can generally save money by replacing only the glazing.
Glass is fragile and it's not unusual for double-pane windows to develop cracks over time. Unless the cracks are caused by mechanical damage or a sudden impact, it's often possible to repair these cracks with epoxy and a small 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 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, such as stress cracks that are caused by low temperatures, from escalating. However, if you're dealing with more severe cracks that have already formed in your glass, it may be better to contact a professional to ensure the safety of the repair.
Attempting to replace just one pane of double-pane glass is a dangerous and challenging DIY task. Double-pane windows are manufactured as a whole unit and sealed in the factory with inert gas, so it would be impossible to remove the glass without damaging the entire window. If you are planning to replace the glass in your double-paned windows choose a brand with a long-lasting warranty.

Condensation Build-Up

It's caused by a disparity between air temperature and humidity levels that cause water vapour to condense upon contact with cold impenetrable surfaces such as windows. This is generally a good thing in winter, as it helps prevent loss of heat.
If your windows look cloudy and have a film of water on them, it is time to call 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.
You can stop this from happening by using dehumidifiers, enhancing ventilation, or by applying de-icing agents. Alternatively, there are several specialists who can repair condensation build-up in double glazed windows by drilling holes in the window unit and then injecting or pumping a special desiccant to remove the excess moisture. This is a more involved procedure that requires the unit to be removed from the frame, allowing access to each pane of glass and thoroughly cleaning them, then refilling with desiccant before sealing them back up. This is typically more expensive, but it's important to make sure the company you choose is licensed and insured with FENSA.
It is important to keep in mind that tampering with your double glazed windows is not advised and could cause the windows to be damaged and invalidate any warranties. If you have a warranty on your windows, it is best to notify the company of any problems as they'll be responsible for the replacement of any defective units under warranty. It is best to consult an expert before undertaking any DIY repairs. This is particularly applicable to older units, as they are sometimes more prone to fail.
