Damaged Glass
Double pane windows rely on an airtight seal in order to function correctly. The most typical sign that a seal may be failing is condensation forming between the glass plates. Condensation between glass plates is not a major problem and can be fixed however, it's an indication that your glass unit requires replacement.

Begin by cleaning over the area that is cracked with a damp cotton rag and then apply epoxy to the crack following the manufacturer's instructions. Allow the epoxy to fully dry before sanding down and painting over the repaired area.
A simple strip of masking tape can also be used to stop a crack from spreading. A single strip of tape on both sides of the damaged area is enough to keep superficial cracks, such as stress cracks that are caused by low temperatures, from worsening. However, if you're dealing with more severe cracks that are already forming in your glass, it could be better to contact a professional to ensure the security of the repair.
