Best Weatherstripping for DIYers
Weatherstripping seals the gaps around doors and windows that leak air, drafts, and dollars. The right type depends on the gap and where it goes; a door sweep plus seals can noticeably cut a heating bill.
What to look for
- ·Match the type to the gap: V-seal (tension) for window sashes and door jambs, foam tape for irregular gaps, door sweeps for the bottom of doors.
- ·Durable EPDM rubber and silicone seals outlast cheap foam, especially on exterior doors that get used and weathered.
- ·Clean and dry the surface first so adhesive seals stick, and measure the gap so the seal compresses without binding the door.

Frequently asked
What type of weatherstripping should I use?+
Use V-seal (tension strip) for window sashes and the sides of doors, adhesive foam tape for irregular or compression gaps, rubber or silicone bulb seals for exterior door jambs, and a door sweep for the gap under a door. Match the product to the gap and wear.
Where do most air leaks happen?+
Around exterior doors (especially the bottom) and window sashes, plus the attic hatch, are the biggest culprits. Sealing doors and windows with weatherstripping and adding a door sweep is a cheap, high-return way to cut drafts and energy bills.
How long does weatherstripping last?+
Cheap foam tape may last a season or two, while quality EPDM rubber, silicone, and metal-backed seals last many years. Exterior, high-traffic doors wear seals fastest, so spend up there and check them each season.
Can weatherstripping really lower my energy bill?+
Yes. Sealing air leaks around doors and windows is one of the cheapest efficiency upgrades and can noticeably reduce drafts and heating and cooling costs. It is a quick DIY with a fast payback, especially on older homes.
How do I install a door sweep?+
Measure the door width, cut the sweep to length, and screw or stick it to the bottom inside face of the door so it just brushes the threshold without dragging. It should seal the gap when closed but not bind when opening.
