DIY replacement
Inspect door seals and fit a matched clip-on weatherstrip
Match the profile and fixing before replacing an accessible push-on seal.
Find where water enters
Dry the door opening and inspect the seal, nearby trim and visible drain openings. Water ingress can originate from glass channels, rust, a membrane or drainage rather than the door seal. Do not cover drain holes or hide rust with adhesive.
Match the profile
Compare the old seal’s cross-section, length, corners and attachment method. Check whether it is push-on, clipped or bonded. Photographs of the end profile and the door opening help the seller identify it. This guide covers a matched, accessible push-on seal; bonded glass seals and structural corrosion need a specialist.
Replace gently
Photograph the joint and routing. Remove only the accessible old push-on strip without levering against paint or disturbing glass. Clean and dry the flange with a finish-safe product. Follow the seal maker’s instructions for the joint location and seating. Fit gradually without stretching; stretching can leave gaps later. Do not cut until the required length and joint are confirmed.
Verify closure
Close the door gently and confirm the latch operates normally without excessive force. Check for even seating and gaps. Use a gentle water check after following any product curing instructions; do not use a pressure washer. If closure is tight or the door alignment is wrong, stop and have it checked.
