How to Repair a Double Glazed Window
Double glazing is an effective way to increase the insulation of your home and increase its energy efficiency. But it can be prone to faults like condensation and draughts.
Repairs are typically more cost-effective than replacement. Let's take a look at the most popular double-glazed window repair options:
Broken Panes
The first step is to remove the broken pane from the frame. Wear thick gloves and put a cardboard box nearby to collect any glass shards that fall during your work. Wear a protective eye mask and mask because of the risk of lead being in the frame. Utilize a utility knife to cut the glazing surrounding the windowpane that has been broken. If clips or nails are securing the windowpane the frame, you can use pliers to pull them out. After the glass has been removed, scrape away any old putty and metal glazing points. A heat gun may help in softering the putty if you need to.
After the old putty is gone after which you can re-grout the grooves, and then apply silicone caulk using a silicon caulking tool. Before applying the final caulking it is a good idea to check the fit of the new window into its frame. Be sure that the grooves are clean of any rust, gunk, or paint and that they aren't too narrow for the windowpane to sit in.
Then you should replace the sash with an appropriate wood molding that matches the windowframe. If the frame of the window is damaged it could be easier and more cost-effective to replace the entire window unit instead of just a single pane.
In the past, double pane windows were constructed of two pieces of glass separated with an air spacer. They were then filled with either air or an insulation gas. In recent years, manufacturers made the switch to insulated-glass units (IGs) which are more energy-efficient and resistant to failure of seals. In windows with a failing IG the moisture from the outside seeps into the gap and condenses inside the glass. This cycle eventually breaks the insulating properties that are present in the IG and leaves an unclean substance on the glass.
To repair a damaged IG, an expert in glass repair can replace the entire unit or can replace only the damaged surface of the glass. This procedure can be costly and time-consuming, however it is the only option for fixing a defective seal that allows water to enter the home.

Misted Panes
The window frame holds two or more panes of glass each separated by an air-filled space. The air, usually filled with argon gas for greater energy efficiency, helps to keep warm air inside and cold air out. However, windows with this feature can break down and you might see a hazy, smokey fog between the glass panes. It might seem like it's time to buy a new window, but it's not possible to just replace the damaged pane.

Mist may also form in the insulating gap between the panes and the glass, indicating that the seal has broken and it's time to make double glazed window repairs double glazing repairs.
Another common issue is that windows are beginning to shrink over time and make it difficult to open and close them. This is typically fixed by adjusting the hinges or mechanisms.
