- The call
- After a spring rain there is a puddle inside the door that reaches the tires. The driveway slopes toward the garage, the slab has a low corner, and the flattened old seal is not making up the difference.

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.
What you have afterwards is a door that closes onto a single soft line of contact from jamb to jamb. Daylight under the door is much reduced, the draft across the floor eases, wind-blown leaves and snow are kept out more effectively, and the tighter gap makes the route in harder for mice. The opener has been reset so the door lands gently on the new strip instead of pressing it flat. You also leave knowing the seal's profile and size, which makes the next replacement a matter of one phone call, and a couple of simple habits for winter that keep the new seal from freezing to the floor.

Garage Door Bottom Seal Replacement · Hanover

Scene 1
A gap that is wider at one corner is often the door rather than the seal. The technician checks that the door sits square in the opening by comparing the bottom edge to the floor at both ends and looking at how each lift cable wraps its drum. A stretched cable, a drum that has crept on its shaft or uneven spring tension drops one corner a centimetre or two, and setting the door level is what closes that wedge. If the door is out of level, the adjustment is explained as its own item and done first, and the seal is then sized to the gap that remains. Getting the order right saves fitting a seal twice.
Scene 2
The opener's release cord is pulled so the motor is out of the picture, and the door is raised by hand to a height where the bottom rail sits at a comfortable working level, usually around chest height. A clamp goes on each vertical track just below a roller so the door cannot drift down while the retainer is exposed. The bottom brackets in each corner stay untouched throughout, because they carry cable tension whenever the springs are wound. With the door held and the floor in front clear, the seal and retainer can be handled like any other piece of hardware.
Scene 3
Before leaving, the technician tells you what went on the door: the seal profile, whether T, bead or bulb, its width and height, the material, the door width it was cut for, and whether the retainer was renewed. Write this on a card by the opener or inside the manual. Bottom seals wear out on a schedule of years rather than decades, and knowing the profile means the next one can be ordered and fitted without measuring from scratch. If a threshold seal was added, its length and type belong on the same card.

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.
