- The call
- With the door closed and the lights off, a bright line of daylight runs along the floor from one side to the other. Leaves and grit have blown in under it and gathered in a neat drift against the back wall.
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.
In plain words
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.

How the visit goes
Scene 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.
Scene 2
Fitting a new retainer where needed
If the inspection found a retainer that is bent, corroded or spread open, it is replaced before the seal goes in. The old extrusion is unscrewed or its rivets drilled out, the bottom rail is cleaned and any rust treated, and a new aluminum retainer is fixed straight along the rail with fresh self-drilling screws, checked with a straightedge so the channels run true. Fastener heads are sealed against meltwater. On a door whose channel was moulded into a plastic bottom cap, a screw-on retainer is fitted over the rail so a standard seal can be used from now on.
Scene 3
Fewer visitors of the four-legged kind
A continuous seal removes the easy route mice and insects used along the floor. If rodents were part of the reason for the visit, a few habits finish the job: keep birdseed, pet food and grass seed in lidded bins, move firewood and cardboard away from the walls, and check the jamb seals at floor level, where a gap beside the door is as inviting as one under it. Seals with a stainless mesh embedded in the vinyl are available for garages that have had repeated trouble. A sealed bottom edge plus tidy corners keeps the garage a place where nothing wants to nest.

What shapes the quoteApplewood Hills Garage Door Co.
- Number of doors
- Two single doors are two seals, two inspections and two opener resets. The travel is shared, so doing both in one visit costs less than two separate calls.
- Seal profile and size
- T-style, bead and bulb profiles in different widths and heights sit at different points on the parts list, and the retainer on your door decides which one is used.
- Opener adjustment
- Resetting the down limit and force and repeating the reversing test after a taller seal is fitted is a short step that the quote names whenever the door has an opener.

What people ask us
Is the seal on an insulated steel door different?
Sometimes. Many insulated doors have the seal channel moulded into a plastic cap that wraps the bottom rail, which takes a specific profile rather than a generic one. If that cap is cracked or the channel has opened, a screw-on aluminum retainer can be fitted over the rail so a standard T-style or bulb seal can be used from then on. Identifying the retainer at the first look settles which route applies.
How do I look after the new seal?
Wipe it clean of salt and grit a few times a year, and give it a light coat of silicone spray each autumn so meltwater has nothing to bond to. Keep petroleum products and solvents away from it, since they soften vinyl. Clear ice and packed snow from the threshold before running the door in winter. Once a season, look under the closed door for daylight. That is the whole routine.
Does a wood garage door use the same kind of seal?
Usually not. Wood doors most often carry a flat or angled strip of vinyl or rubber nailed directly to the bottom rail, rather than a profile that slides into a retainer. Replacement means removing the old strip and nails, checking the rail for soft or cupped wood, and fastening a new strip so its lip angles outward and meets the floor along the full width. A retainer can be added to a sound rail if you prefer a channel seal.

2021 census: what it means at the door
Every square is one home in a hundred.
- 38 in 100 homes · mixed ages
- 37 in 100 homes · mostly attached
- About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.Where housing ages are mixed, many older houses have already had a newer door and opener fitted, so the door's age and the house's age are not the same thing. The technician reads the door itself, its spring type, tracks and opener, before recommending anything.
- Single-detached houses make up about 37% of homes in Mississauga (2021 Census).Townhouses built in rows tend to have identical doors from the same builder, so when springs and openers age they do so together along the street. Owners often arrange service for several doors at once, and we can plan a single visit that covers the row.
