How to Repair a Double Glazed Window
Double glazing is a good method to increase the efficiency of your home's energy use and help to insulate it. But it can be prone to faults like condensation and draughts.
Repairs are often more cost-effective than replacement. Let's look at a few of the most popular solutions for double-glazed window repairs:

Broken Panes
The first step is to remove the broken pane from the frame. Wear thick gloves and put a cardboard box close by to catch any glass fragments that fall as you work. Wear a protective eye mask and mask due to the possibility of lead in the frame. Utilize a utility knife to cut through the glass around the windowpane that has been broken. Make use of pliers to take out any clips or nails that are securing the windowpane. Scrape away any old putty or metal glazing points after the glass has been removed. If required, a heating gun can be used to soften the putty.
After the old putty has been removed then re-grout the grooves and apply silicone caulk using a silicon caulking tool. It's a good idea test the fit of the new window inside its frame prior to applying the final caulking. Check that the grooves in the frame are free of paint, rust, or gunk, and aren't too narrow to accommodate the window.
Replace the sash with a wood moulding to match the frame. If the window frame has become damaged it is much easier and more cost-effective to replace the entire unit than only a single pane.
In the past windows with double panes were constructed of two pieces of glass separated with a spacer. They were then filled with air or an insulation gas. In recent years, companies have 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 air moisture from outside seeps through the gap and condenses inside the glass. This process eventually erodes the properties of insulation, leaving an opaque film on the glass.
A glass repair professional can replace the entire IG or only the damaged surface. It can be a lengthy and costly process, however it is the only option to fix a defective seal that lets water into the home. Selecting high-quality windows from a trusted manufacturer and then having them installed by an experienced technician will help avoid future issues with the seals.
Misted Panes

You may think it's time to replace the entire window but it's not as easy as simply removing the broken pane and replacing it.
