Air leaking around an exterior door can affect comfort. The US Department of Energy describes weatherstripping as a measure for door and window gaps. For apartment entry or fire-rated doors, follow building rules and door certification requirements first.

Your try-it-at-home checklist

0 / 6 done

With the door shut, feel for air moving around its edges. Avoid flames or smoke for testing.
Inspect seals near the hinges, latch side and bottom for tears, compression or gaps.
Check your door model and building rules; do not obstruct a fire-rated door, combustion-air inlet or required vent.
For user-replaceable seals only, match the original size and clearance and follow product instructions.
After fitting, repeatedly check that the door shuts, latches and opens quickly in an emergency.
If the door is warped, leaks water or has fire-rating implications, consult building management or a qualified technician rather than altering it.
