The US Department of Energy distinguishes weatherstripping for moving joints from caulk for stationary cracks. Never seal designed vents or obstruct fire exits.

Your try-it-at-home checklist

0 / 6 done

1. With the door shut, locate draft or light gaps without blocking vents or an emergency exit.
2. Distinguish a moving door-to-frame joint from a fixed crack between framing and wall.
3. Choose appropriately sized weatherstripping for moving gaps; consider compatible caulk only for stationary gaps.
4. Clean and dry the contact surface, and cut the strip to fit as the manufacturer specifies.
5. Open, close and latch the door repeatedly to check that the seal does not interfere.
6. Monitor drafts and condensation; consult building management or a professional before modifying fire-rated or shared doors.
