Preventing Frost/Ice Damage on Windows

Keep your house windows frost-free in the winter to protect them from damaging moisture buildup.

Windows develop frost when the cold air from the outside cools the window’s glass, causing condensation to form when the house’s warmer air comes into contact with the window. The resulting moisture can then freeze if the temperature outside is cold enough. 
Wet or frosted windows can cause damage to the surrounding paint and wood of the windows, requiring costly repairs and possible window replacement. 

Proper window insulation at installation is key to keeping moisture at bay. Little insulation again allows cold air to push into the dwelling space condensing moisture in the air, which causes water buildup or ice in extreme situations.

Here are tips to prevent frost or ice from forming on your windows:

Re-insulate your windows.

Weatherize your windows

Seal the outside edges of the window casing with caulk

Replace any worn weather striping found inside the window tracks

Warm your house

Keeping your house at a steady temperature can help prevent your windows from frosting over.

Replace your windows

Replace single-pane windows with double-pane windows. This is the most cost-effective in the long run.
