- The call
- The strip under the door has gone as hard as a hose left out for ten summers. Press it and it does not give; bend it and it cracks. Where the door meets the floor it sits on the concrete without squashing at all.

One end of the bottom seal has slipped out of its channel and hangs down like a loose shoelace. Each time the door closes it folds under, each time it opens it flaps, and the gap beside it keeps growing.
The material matters as much as the shape when the garage sees real winters. Vinyl is the common choice: it resists moisture and sun well but grows stiff in deep cold and stops moulding itself to the concrete. Rubber stays supple at low temperatures and follows an uneven floor, though it can harden after many years of sun. Silicone keeps its flexibility through hot and cold alike and resists cracking, at a higher cost per metre. Choosing the right compound for a door that faces the weather is part of the service, and it is one reason a replacement seal often outlasts the one it replaces.

Garage Door Bottom Seal Replacement · West Grey

Scene 1
The aluminum or plastic retainer that grips the seal is inspected along its full length. The technician looks for kinks where something struck it, channels that have been spread open, corrosion where salt has sat, and screws that have rusted or pulled loose from the rail. A retainer that is straight and tight is reused; one that is damaged is measured for a matching replacement so both channels line up with the new seal. On doors where the retainer is part of a plastic bottom cap, a cracked cap is noted and a screw-on aluminum retainer is offered as the practical repair.
Scene 2
Both edges of the new seal are started into their channels together at one end of the door. A spray of soapy water or silicone on the edges lets the strip glide, and the technician works it across in stages, pulling gently from the front end and feeding from the other so the seal is never stretched, since a stretched seal shrinks back and leaves a gap later. Once it is across, the bulb is checked to hang evenly with no twists. The ends are trimmed flush with the door and folded up into the channel or capped, so water running along the seal drains out rather than into the section.
Scene 3
With the bottom sealed, any remaining draft points to the perimeter: the vinyl fin on the stop moulding at the jambs and header, and the joints between sections. These were looked over during the visit and anything torn, shrunk or missing was pointed out. Replacing perimeter stripping is straightforward work that can be planned for a mild day. Together with a sound bottom seal and, where the floor calls for it, a threshold, the garage gains a stronger barrier against wind, water and cold on all four edges, and an attached garage can stay closer to the temperature of the house.

FeesSame any hour
Plan on an hour or two for a straightforward replacement on a standard door, including the inspection and the opener reset. A retainer replacement, a hardened seal that has to come out in pieces, a wood door with a nail-on strip or the addition of a threshold seal each add time. The technician will give you a realistic window once the door has been looked at.
The technician maps the gap with the door closed, checks the door is level and the bottom section straight, and identifies the retainer and profile. The opener is disconnected and the door clamped at working height. The old seal comes out, the channels are cleaned, a new seal is cut and fed in, and any retainer work is done. The door is then closed under power, the opener reset, and the reversing and photo-eye tests run.
Only if the existing one is damaged, and most are reused. A retainer that is straight, tight to the rail and free of heavy corrosion stays. One that has been kinked by a bumper or shovel, spread open so the seal slips out, or eaten by salt is replaced with a matching aluminum extrusion so the new seal seats properly. The inspection at the start of the visit settles which applies.
