Drafts come from two places: the gap along the sash or jamb, and the gap under the door. Those need different products. We pair a self-adhesive V-seal for jamb gaps with a screw-on door sweep for the threshold, so you seal the whole opening.
A cheap, effective compression seal for drafty double-hung windows and door jambs with narrow gaps. Clean the surface well first, since adhesion is its weak point.
- Drafty windows
- Drafty doors
- Air sealing
Pros
- V-shaped hinge springs open to seal irregular gaps while still letting the window or door close
- Adhesive is formulated to bond even in sub-freezing temperatures for winter installs
- No tools or fasteners needed; you just peel, cut to length, and press into the jamb channel
Cons
- Self-adhesive can lose grip over a few seasons, especially on dusty or previously painted wood
- Only suits narrow gaps; wide or uneven jamb gaps need foam tape or a different profile
- Vinyl is not paintable and the white/bronze strip stays visible along the frame
The correct fix for cold air pouring under an exterior door. More work to install than tape, but it seals the threshold gap durably and is adjustable for uneven floors.
- Drafty doors
- Air sealing
- Blocking under door drafts
Pros
- Seals the under-door gap that V-seal and foam tape cannot reach, a top source of drafts
- Slotted screw holes let you adjust height for an even seal against an uneven threshold
- Rigid aluminum carrier is far more durable than stick-on foam or brush sweeps
Cons
- Requires drilling and screws, so it is a slower install than peel-and-stick options
- Must be cut to the exact door width with a hacksaw, adding a step for non-standard doors
- A too-low setting drags on the floor and wears the vinyl blade or scratches flooring
Frequently Asked Questions
- What weatherstripping should I use for a drafty window?
- A folded vinyl V-seal is the usual pick for double-hung window sashes and jamb gaps. Its hinge compresses to fill the gap while still letting the window open and close. For very wide or uneven gaps, use a foam or EPDM tape instead.
- How do I stop cold air coming under my door?
- Install a door sweep on the bottom of the door. A screw-on aluminum-and-vinyl sweep is durable and adjustable for uneven thresholds, which stick-on foam tape and V-seal cannot reach.
- Does self-adhesive weatherstripping last?
- It is the fastest to install but the adhesive can fail after a few seasons, especially on dusty, cold, or painted surfaces. Clean the surface with alcohol first, and choose a screw-mounted sweep for high-wear spots like door bottoms.
