How to repair window a Double Glazed Window

Double glazing is an effective way to insulate your home and improve its energy efficiency. However, it can be susceptible to faults like condensation and draughts.

In the past, double-pane windows were just two pieces of glass separated by a spacer and then filled with air or an insulating gas. In recent years, manufacturers have switched to insulated glass units (IGs) which are more efficient in terms of energy efficiency and resist seal failure. In windows with a failing IG the air moisture from outside seeps into the gap and condenses inside the glass. This cycle eventually breaks the insulating properties of IG and leaves an odourless residue on the glass.

A glass repair specialist can either replace the entire IG or only the damaged surface.
