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. However, it can be susceptible to problems like condensation and draughts.

A heat gun can be used to soften the putty, if needed.
Once the old putty has been removed then re-grout the grooves, and apply the new silicone caulk using a silicone caulking gun. Before applying the final caulking it's a good idea to test fit the new window into its frame.

In the past double-pane windows were two pieces of glass that were separated by a spacer and then filled with air or an insulating gas. In recent years, manufacturers have switched to insulated-glass units (IGs) that are more energy efficient and resistant to failure of seals. In a double-pane window with a damaged IG the moisture from the surrounding air is absorbed into the gap and then condenses inside of the glass. This cycle eventually breaks down the properties of insulation and leaves a film of haze on the glass.
A glass repair professional can either replace the entire IG or only the damaged surface. This procedure can be costly and time-consuming, but it is the only way to fix a defective seal that allows water to leak into the home.

The space that is used to insulate between the panes could also mist up, indicating that there is a broken seal.
