How To Winterize Windows Everything You Need To Know. In this video, we're going to talk about how to winterize windows.

Weatherstripping
You can winterize your windows by sealing them with strips of foam, rigid gaskets, or rubber tubing.

Caulking
To prevent cold air from leaking into the house through the windows, seal the gaps along the exterior perimeter and the cracks between the wall and the interior trim with caulk.

Using draft snakes
This involves filling old socks, sweatpants, or long sleeves with dense materials like dry ice, then laying them along the base of your windows.

Using shrinkwrap kits
You can purchase a shrinkwrap kit at a home improvement store near you, then use it to obtain an airtight seal for your windows during winter.

Using window inserts
This is the most effective and preferred method of winterizing windows during the cold season.
