Weatherstripping doors and windows
Choosing the right weatherstrip and installing it in an afternoon.
Worn weatherstripping is one of the most common leaks, and one of the easiest to fix.
Types
- Adhesive foam tape: cheap and easy for low-traffic spots
- V-strip (tension seal): durable for the sides of sash windows and doors
- Door sweeps: close the gap under exterior doors
- Tubular rubber or vinyl: for door jambs, more durable than foam
Install
- Clean and dry the surface.
- Measure twice; cut to fit snugly at corners.
- Close the door or window to check for an even seal without forcing it.
