Inspect & Replace Door & Window Weatherstripping

Seal air leaks around doors and windows with new weatherstripping to cut heating and cooling costs and stop drafts.

Supplies You'll Need

• Replacement weatherstripping (foam, felt, or rubber)
• Utility knife or scissors
• Measuring tape
• Screwdriver or pry bar (if removing old molding)

Step-by-Step Instructions

1. Close all exterior doors and windows and look for visible gaps or daylight showing through.
2. Hold a lit incense stick or feel for drafts around each frame to find leaky spots.
3. Measure the length of each gap and purchase matching foam, rubber, or felt weatherstripping from a hardware store.
4. Remove old cracked or peeling weatherstripping with a utility knife or pry bar.
5. Clean the contact surface with rubbing alcohol and let it dry completely.
6. Peel and stick new weatherstripping firmly along each door and window frame.
7. Close each door and window to test for a tight seal with no visible air gaps.
