Do you have water condensation on your windows?

Moisture around the edges of your windows that you can wipe off

If you see condensation on your windows, it is a sign of other problems in your home. Unless the source of condensation is found, damage to your windows will result, as well as damage to unseen areas of your home. Repairing damage without curing the underlying source will only result in the same condition down the road.

Damage to windows from condensation is not covered by the FarNorth warranty.
