Garage Door Bottom Seal Replacement
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.

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.
How the visit goesThere are mouse droppings along the wall behind the recycling bins, and at one bottom corner of the door the vinyl has a neat chewed notch the width of a thumb. Something has found its way in for the winter.

How the visit goes

- 1
Reading the gap with the door closed
The assessment starts with the lights off and the door down. From inside, the technician looks along the floor line for daylight and notes where it shows: a thin line the full width, a wedge at one corner, or a patch in the middle. A straightedge laid across the threshold shows whether the slab is flat or dished, and a hand run along the seal feels where it touches and where it hovers. Photographs of the worst spots are taken so you can see what is being fixed. This map of the gap tells the technician how tall the new seal needs to be and whether anything other than the seal is contributing.

Securing the door before work begins
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.

The rest of the weather line
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.

What affects the quote
- 1
Rodent-resistant seal
A profile with embedded stainless mesh for a garage that has had repeated chewing costs more per length than plain vinyl and is offered where the history calls for it.
- 2
Perimeter seals done together
Jamb and header weatherstripping renewed in the same visit is quoted per length of stop moulding, and doing it alongside the bottom seal saves a second call-out.
- 3
Door out of level
If one corner of the door hangs low because of cable or spring tension, levelling the door is separate work done before the seal goes in and is priced on its own.

Garage Door Bottom Seal Replacement: questions
What is the difference between T-style, bead and bulb seals?
The names describe the edge that grips the retainer and the shape of the part that meets the floor. A T-style seal has T-shaped edges that slide into slotted channels along the bottom rail. A bead seal has round edges for the rounder channels found on many older steel doors. A bulb, or U-style, seal is a larger tube that compresses further and suits rough or dished floors. The retainer on your door decides which one fits.
Is this something I can do myself?
Many homeowners do, and a technician's value lies in the parts that go wrong: identifying the exact profile so the seal seats, freeing a strip that has fused into its channel, spotting a retainer or door-level problem behind the gap, and resetting the opener's limit and force so the door lands gently and still reverses on an obstruction. If you would rather have it measured, fitted and tested in one go, that is what the visit is for.
Can mice get past a garage door bottom seal?
A worn, hardened or chewed seal is one of their favourite routes, and even a small gap at a corner is enough. A fresh, continuous seal sized to the floor removes that route. For a garage with repeated trouble, seals with a stainless mesh embedded in the vinyl are available and resist chewing. Keeping the jamb seals sound at floor level matters just as much, since a gap beside the door serves them equally well.

What the census means at the door
52%
Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.
Older houses frequently have a garage door that was replaced once already, sometimes with a door chosen for the opening rather than the building. When that door reaches its end, there is a chance to pick a style that suits the house properly, and we measure with that in mind.
49%
A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).
In a neighbourhood with both detached and attached homes, some customers decide alone and others report to a board or property manager. We adapt the visit accordingly, giving a homeowner options at the door and a manager a written summary they can circulate.
