Double Glazed Windows Repairs
Double-glazed windows may require repair for many reasons, including condensation between the panes, draughts or sagging frames. Fortunately, a majority of problems can be addressed.

Broken Panes
When a window pane is damaged, it loses its insulation properties and could cause draft.

A damaged window should be repaired by an expert to ensure you get a proper seal and optimum energy efficiency.

If there's any sign of corrosion, the clips must be replaced with new ones. If the window is made of wood the glazier points can be reused if still in good shape.
The next step is to prepare the surface of the remaining frame for reglazing. Using a caulking gun, apply a continuous ribbon of compound along the inside edge of the recess. Make use of a premium putty such as glazier's compounds that is available in a cartridge or conventional compound sold in a can. Let it dry before installing the glass.

Condensation

A broken window seal can be repaired by replacing it with a new one by an experienced glazier. This can be expensive and may not completely solve the fog issue. Some companies offer defogging which involves putting a vacuum pump inside the window frame to remove moisture and clear the glass.
