How to Repair a Double Glazed Window

Double glazing is an effective method to increase the insulation of your home and increase its energy efficiency. It could cause problems like condensation and draughts.

It is a good idea to examine the fit of the new window inside its frame before applying the final caulking. Check that the grooves in the frame are not contaminated by paint, rust or gunk, and are not too narrow to accommodate the window.

In windows with a failing IG the air moisture from outside reaches the glass and condenses inside the glass. This cycle eventually breaks down the insulating properties and leaves a film of haze on the glass.
