Doorway drafts are unwelcome at any time of year, especially during the winter months when heat is precious. Making sure your home is well-insulated against drafts is an important part of reducing your energy consumption and lowering your heating bill. There are several ways you can stop drafts from your doors, varying in price and overall effectiveness. The exact method you choose will depend on the location of the draft in the doorway and your budget.
Cut weatherstrip adhesive to fit the length you measured on the bottom of your door.
Wipe off the bottom of the door using paper towels and a cleaning product. Dry it thoroughly so the adhesive will stick.
Peel off the paper backing of the weatherstripping adhesive and place it over the surface on the bottom of the door. This will help stop drafts from coming in under the door.
