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 these issues can be resolved.

Broken Panes

If a window pane is broken and shattered, it loses its insulation and may cause drafts. If the dividing muntins are broken it can cause moisture to leak between the glass panes, resulting in condensation, mould and mildew and making your home less energy efficient. It is recommended to have a professional repair a broken window to ensure the best seal and energy efficiency.

First, you'll need to take out any broken glass. Begin by placing a cheap glass cutter in a hardware store under the broken pane. It's recommended to lubricate the cutter with light oil prior to when you begin. This will prevent the glass from breaking too easily. You can then use the tool's ball-shaped end to loosen the pieces and the glass should break away quickly.

Scrape any old glazing compound out of the frame's recess after the glass is removed. This will expose the glazier's clips and pins that hold the glass in place. If there's any sign of corrosion, these should be replaced with new ones. If the window is wooden, the glazier's points can be used again if they're intact.

You'll need to prepare the surface of the frame to be re-glazed. Using a caulking gun, apply a continuous strip of compound around the inside edge of the recess. Use a high-quality putty, such as a glazier’s compound in a cartridge. Allow it to dry prior to re-inserting the glass. Install the metal clips if they are on the frame. Install the dividers.

Condensation

Condensation is a concern for double-glazed windows, especially during winter. It is typically caused by high moisture levels within your home. Warm air meets cold glass, which condenses into droplets of water. These droplets then accumulate in the corners or frames of the window.

If the seal has been blown it will allow water vapour to pass through your home through the gap, which will cause condensation between the panes that is not able to be cleaned off.
