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 goesEvery mild afternoon the snow melts off the car, runs to the door, and by morning the rubber strip along the bottom is frozen to the concrete. Last week the opener lifted the door and left half the seal on the floor.

How the visit goes

- 1
Why the old seal failed
The old strip is read for its history before it comes off. Cracks along the fold and a chalky surface point to sun and age. A flattened bulb that no longer springs back is compression set. A torn edge at one end usually means the seal froze to the floor and the opener pulled it free. Chew marks say rodents. A strip that has slid partly out of its channel points to a bent or opened retainer, or to a seal that was slightly the wrong size. Each of these leads to a different choice of material, profile or retainer work, so the new seal is spared the fate of the old one.

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.

A clear threshold through winter
The seal closes onto whatever is on the floor, so the threshold deserves a moment when you clear the driveway. Push packed snow and the ridge of ice that forms where the door meets the slab away from the opening before running the door, and sweep salt piles and grit clear of the line so they are not ground into the strip. Park a little further in, if the garage allows, so drips from the car fall on the floor rather than at the seal. These are the same habits that protect the bottom brackets and cables in the corners.

What affects the quote
- 1
Threshold seal added
Where a floor threshold is recommended, its length, its type, whether rubber or aluminum-backed, the adhesive and the floor preparation before it is laid appear as a line of their own.

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.

Wood door nail-on strip
A wood door with a nailed strip takes a different product and more fastening time than a channel seal, and adding a retainer to a wood rail is a further option to consider.

Garage Door Bottom Seal Replacement: questions
How do I know which size and type my door takes?
Look at the end of the bottom section for the metal or plastic strip that holds the seal. Count the channels, note whether they are slotted or rounded, and measure the distance between them and the width of the door. A photo of the end of the retainer and one of the seal's cross-section is usually enough for the technician to identify the profile before the visit and bring the right roll.
Why is the gap much bigger at one corner?
Two causes are common. The door may be hanging out of level because a lift cable has stretched, a drum has crept on its shaft or spring tension is uneven, which drops one corner. Or the slab may have settled or heaved at that end so the floor falls away. The technician checks both before choosing a seal, since a level door and the right seal height together close a wedge-shaped gap.
What information helps when I book?
The width of the door and whether it is a single or double; what is getting in, whether light, drafts, water, snow or pests, and where along the door; whether the gap is even or worse at one end; the door material; and a photo of the end of the bottom section showing the retainer and seal. Mention if the seal has frozen to the floor or if the door has been reversing before it closes.

What the census means at the door
15%
Newer homes. About 15% of homes in Richmond Hill were built in 1980 or earlier, according to the 2021 Census.
Newer garages tend to have generous headroom and a finished ceiling, so options such as a jackshaft opener mounted beside the door, or a high-lift conversion for a car hoist, are practical. The technician checks the space and explains what would fit.
57%
A mix of homes. Single-detached houses make up about 57% of homes in Richmond Hill (2021 Census).
Where housing is varied, security needs vary too. A detached home wants its garage door closing fully and its interior door respected; a townhouse or condo wants old fobs and remotes cleared and the shared entrance working. We address whichever applies at each door.
