Damaged Glass

Double pane windows rely on an airtight seal to work effectively. Condensation between the glass plates is a typical sign of a faulty seal.

Double-paned windows may develop cracks due to the fragility of glass. If the cracks aren't caused by mechanical damage or an unusual impact on the window, they can be repaired with epoxy and elbow grease. Follow the directions of the manufacturer and scrub the crack by using a damp cotton cloth. Then apply the epoxy to the crack. Allow the epoxy to fully dry before sanding down and painting over the repaired area.
