How to Repair Double Glazed Windows

Double glazing is usually covered by a warranty for 10 or 20 year. If your double-glazed windows are showing signs of aging, you could be eligible to have them repaired under warranty.

Double-glazed window repair requires replacing the seal on your existing glass. Misting is a clear indicator that the seal is broken and you will need to get it repaired.


Glass damaged

Double pane windows rely on an airtight seal to function effectively. The most typical indication that a seal is failing is condensation forming between the glass plates. While condensation between glass isn't an issue that is serious and can be dealt with, it's typically a sign that the glazing unit requires replacement. If you have an older double glazed window, this may require replacing both the glass and the frame. If the frame is in good condition, however, you can usually save money by replacing just the glass.

Double-paned windows may develop cracks due to the fragility of glass. Unless the cracks are caused by mechanical damage or an unusual impact, it's often possible to repair these cracks using epoxy and little bit of elbow grease. Follow the manufacturer's instructions and scrub the area of the crack using a wet cotton cloth. Then, apply epoxy to the crack. Allow the epoxy to dry completely before sanding and painting over the repaired area.

A simple strip of masking tap can also be used to prevent cracks from spreading. A single strip of tape on both sides of the damaged area is enough to keep superficial cracks, like stress cracks that result from low temperatures, from worsening. If you have deeper cracks in your glass that are already present, it's best to contact an expert for repair.

This is a more complicated procedure that requires the sealed unit to be removed from the frame, allowing access to each pane of glass and thoroughly cleaning them, then filling them with desiccant and sealing up again.
