- The call
- The gap under the door is a finger wide at one end and nothing at the other. The door itself looks straight, but the floor drops away toward the corner where the slab has settled, and drafts pour through the wedge.
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.
In plain words
The bottom seal, called an astragal in the trade, is the flexible strip along the underside of the lowest door section that squashes against the floor when the door closes. On most steel doors it is a U-shaped vinyl or rubber profile whose two edges slide into the channels of a retainer fixed to the bottom rail; on wood doors it is often a flat angled strip nailed in place. Replacing it means matching that retainer and profile, fitting a fresh seal the full width of the door, and confirming it meets the floor in one continuous line so light, drafts, water and pests lose their route in.

How the visit goes
Scene 1
Retainer condition and fasteners
The aluminum or plastic retainer that grips the seal is inspected along its full length. The technician looks for kinks where something struck it, channels that have been spread open, corrosion where salt has sat, and screws that have rusted or pulled loose from the rail. A retainer that is straight and tight is reused; one that is damaged is measured for a matching replacement so both channels line up with the new seal. On doors where the retainer is part of a plastic bottom cap, a cracked cap is noted and a screw-on aluminum retainer is offered as the practical repair.
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
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 shapes the quoteInnisfil Garage Door Co.
- 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.
- 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.
- Condition of the old seal
- A supple strip slides out in a minute. One that has hardened and seized in its channel, or been torn and frozen into the corners, has to come out in pieces, which takes longer.

Things people wonder
What are bottom seals made of, and which suits cold weather?
Most are vinyl, which resists sun and moisture well but stiffens in deep cold. Rubber compounds stay flexible at low temperatures and follow an uneven floor closely, though they can harden after many years of sun. Silicone stays supple in heat and cold and resists cracking, at a higher cost. For a door that faces the weather, a rubber or silicone profile is usually the sounder long-term choice.
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.
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.
Repair & Maintenance
- Garage Door Tune-UpYou pulled the red cord to lift the door by hand during a power cut and it felt like lifting a car.
- Off-Track Garage Door ResetThere was a loud bang from the garage, then silence.
- Garage Door Panel ReplacementAfter an overnight freeze the door stuck to the slab, the opener strained, and something gave.
- Garage Door Perimeter WeatherstripAfter a windy night there is a fine ridge of snow on the garage floor along one side of the door, and another across the top step.
- Garage Door Manual Lock RepairYou pushed the slide bolt across like always, but tonight it stops short of the slot in the track and springs back.

2021 census: what it means at the door
Every square is one home in a hundred.
- 35 in 100 homes · mixed ages
- 90 in 100 homes · mostly houses
- About 35% of homes in Innisfil were built in 1980 or earlier, according to the 2021 Census.Where homes of different ages sit together, the common thread is that every door eventually needs springs, rollers, seals and a balance check. What differs is the spring type and the size, so the technician measures and matches rather than fitting a standard part.
- Single-detached houses make up about 90% of homes in Innisfil (2021 Census).In neighbourhoods of detached homes the garage door usually faces the street and takes up much of the front of the house, so its condition shapes how the whole property looks. A straight, quiet, well-finished door is as much a part of the curb appeal as the front door.
