- 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
Not every gap under a garage door is the seal, so the service begins with finding out what the gap is. A strip of light the whole width usually means a seal that has flattened or hardened. A gap at one corner only points to a door hanging out of level or a slab that has settled there. A gap in the middle suggests a bowed bottom section or a crowned floor. Reading these before choosing a seal means the new strip is sized to fill the space that is really there, and any door or floor issue is named and dealt with rather than hidden behind a thicker bulb.

How the visit goes
Scene 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.
Scene 2
Taking the old seal out
With the door secured, the ends of the old strip are freed from any caps or folds and the seal is drawn out of its channels from one end. A supple seal slides; a hardened one is coaxed with a flat blade and a little silicone, or cut into short lengths and removed a piece at a time. Old nails come out of a wood rail with a claw. The channels are then cleaned of grit, rust flakes, salt crust and any remnants of the previous strip with a wire brush and a scraper, because a clean channel is what lets the new seal feed through without tearing.
Scene 3
A door that meets the floor in one line
The first thing you notice is the absence of daylight. With the door closed and the lights off, the floor line is dark from one jamb to the other, and the draft that used to move across the floor is much reduced. The door lands softly, because the opener now stops when the seal is gently compressed rather than driving the section into the concrete. Leaves, grit and drifting snow are kept out far more often. If you crouch and look, the new bulb sits evenly along the slab, filling the low corner the old strip used to hover above.

What shapes the quoteApplewood Hills Garage Door Co.
- Door width
- A single door takes a shorter length of seal than a double, and the widest doors need more time to feed the strip evenly across. The quote starts from the width measured on the day.
- 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.
- Season and conditions
- A seal frozen to the slab, ice at the threshold or working in deep cold adds time for freeing the old strip, clearing the line and keeping the new roll warm enough to feed.

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.
