Safety: Garage doors are heavy and spring/cable systems can be under significant tension. Do not loosen or disassemble high-tension hardware unless you are qualified to do so.
Signs a Seal Is Worn
Visible gaps, brittle rubber, missing sections, daylight under the door, or repeated debris intrusion can indicate weatherstripping needs attention.
Bottom and Perimeter Seals
Different doors use different retainers and seal profiles, so the correct replacement depends on the existing door and track system.
Check Door Alignment First
If the door does not sit evenly on the floor, a new seal alone may not solve the gap. Balance, track, cable, or floor issues may also be involved.
