How to Repair a Double Glazed Window
Double glazing is an effective way to improve the efficiency of your home's energy use and protect it. It can have problems like condensation and draughts.
While replacing windows is the obvious answer to these issues however, repairs are often a much more affordable alternative. Let's look at a few of the most popular options for double-glazed window repairs:
Broken Panes
The first step is to remove the broken pane. Wear thick gloves and place a cardboard box close by to collect any glass fragments that fall while you work. Wear a protective eye mask and mask in case of lead being in the frame. Use a utility blade to cut through the glass around the windowpane that has been broken. If clips or nails are securing the windowpane, use pliers to pull them out. Scrape away any old putty or glazing points after the glass has been removed. A heat gun can be used to soften the putty, if needed.
After the old putty has been removed after which you can re-grout the grooves, and then apply silicone caulk using a silicon caulking tool. It's a good idea test the fit of the new window in its frame prior to applying final caulking. Check that the grooves in the frame are not contaminated by paint, rust or gunk and are not too narrow to fit the window.
Replace the sash next with a wood moulding to match the window frame. If the frame of the window is damaged it could be easier and more cost effective to replace the entire window unit rather than one pane.
In the past, double-pane windows were just two pieces of glass that were separated by a spacer and then filled with air or an insulating gas. But in recent years, manufacturers have switched to the use of insulated glass units (IGs) that are much more efficient in terms of energy efficiency and resist seal failure. In windows that have failed IG moisture from the air outside seeps through the gap and condenses inside the glass. This process eventually damages the insulating properties that are present in the IG and leaves an unclean substance on the glass.
To repair a damaged IG, a glass repair specialist can replace the entire unit or can replace only the damaged surface of the glass. This can be a time-consuming and costly process, however it is the only way to repair a leaky seal allowing water into the home. Purchasing high-quality windows from a trusted manufacturer and having them installed by a skilled technician can prevent further problems with the seals.
Misty Panes
The window frame houses two or more glass panes, each separated by an air-filled space. The air, usually filled with argon gas for more energy efficiency, aids to keep warm air inside and cold air out. However, in some cases, these windows begin to crack and you'll notice a cloud of haze growing between the panes of glass. It might seem like it's time to buy a new window, but you aren't able to just replace the damaged pane.

The mist or condensation means that moisture has penetrated and is causing damage to the insulation qualities of double-glazing. This is why it's essential to pay attention to the maintenance of your windows and keep them clean.
If you see condensation between the glass panes it is a sign that there is too much moisture in your home.

If the condensation is only visible on one side of your window or between the panes, you will require having the seal replaced.
There is no such thing as resealing a double-glazed window to restore its original energy-efficiency. When the seal breaks, the gap allows cold air to enter your home and warm air to escape. This reduces the insulation power of your house which will make it more expensive to heat.
Some companies will make holes in the panes of your window's exterior to drain the condensation. But, this is a temporary solution that is unlikely last longer than six months. It's also not recommended that you try to do this yourself, as it can be very dangerous without the right tools and knowledge. A double-glazing expert will use special equipment to eliminate the condensation and install air vents to help prevent future misting.

This can cause one or both glass sheets to shift slightly and cause a break in the seal, which can cause misting. The space between the panes could also mist up, indicating that there is a broken seal.

This is usually an indication of deterioration in the seals or a problem with the insulating material between the panes.
Condensation between the panes is a different issue that double-glazed windows may cause. This is due to the warm air inside your house being warmer than the cooler air outside. The warmer air expands due to the difference in temperature which could cause window seals to weaken or break over time.
Foggy windows are also a common issue with double-glazed windows. The good news is that this is a problem that can often be solved without having to replace the IGU. This is an indication that your window's seals need to be replaced.
