Tools & materials
- Replacement weatherstrip (kerf-in foam or adhesive type)
- Door sweep (optional)
- Utility knife or scissors
- Tape measure
- Rubbing alcohol
Step by step
- Step 1
Close the door and look for daylight or feel for drafts along the sides, top and bottom.
- Step 2
Pull the old weatherstrip out of the frame groove, or peel and clean off the old adhesive.
- Step 3
Measure each side and cut new weatherstripping to length.
- Step 4
Press kerf-style strips into the groove, or clean with alcohol and apply adhesive strips to the stop molding.
- Step 5
Check the bottom and replace a worn door sweep if light shows under the door.
- Step 6
Close the door. It should seal snugly but still latch without slamming.
