- 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.
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.
In plain words
A seal visit runs in a set order. With the door closed, the technician looks for daylight along the floor line and notes whether the gap is even or concentrated at one point. The door is checked for level and the bottom section for straightness, then the retainer is identified and measured. The opener is disconnected and the door secured before the old strip comes out and the channels are cleaned. A new seal, cut a little long, is fed into the channels and trimmed. Finally the door is closed onto the new seal, the opener's limits are reset, and the reversing test is run before the tools go away.

How the visit goes
Scene 1
Is the door hanging level?
A gap that is wider at one corner is often the door rather than the seal. The technician checks that the door sits square in the opening by comparing the bottom edge to the floor at both ends and looking at how each lift cable wraps its drum. A stretched cable, a drum that has crept on its shaft or uneven spring tension drops one corner a centimetre or two, and setting the door level is what closes that wedge. If the door is out of level, the adjustment is explained as its own item and done first, and the seal is then sized to the gap that remains. Getting the order right saves fitting a seal twice.
Scene 2
Wood doors and nail-on strips
A wood garage door usually carries a flat or angled strip of vinyl or rubber nailed directly to the bottom rail rather than a channel seal. The technician removes the old strip and nails, checks the rail for soft spots and cupping, and treats or dries damp wood as needed. The new strip is positioned so its lip angles toward the outside and touches the floor along the full width, then fastened with galvanized nails or screws at close, even spacing so it cannot ripple. On a rail that follows an uneven floor, the strip's flexibility takes up the difference.
Scene 3
The opener stays in step with the seal
The opener was reset to the new seal height, and it will hold that setting until something changes. If the door begins to reverse just before the floor, stops short and leaves a gap, or lands with a thump, the down limit or force has drifted or the seal has taken a set, and a small adjustment puts it right. The reversing test with a 38 mm (1.5 in) solid object, or a 2x4 laid flat under the door, is worth repeating monthly and after any adjustment, as the industry checklist for homeowners describes. A door that closes gently and reverses on an obstruction is one whose seal and opener are working together.

What shapes the quoteRouge Valley 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.
- 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.
- Bottom section repairs
- A rusted, dented or bowed steel bottom rail, or a rotted wood rail, is pointed out and any repair or reinforcement offered as an option beside the seal work.

The questions that come up
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 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.
How long does a bottom seal last?
Several years is typical, with the range set by exposure. A door facing south or west, a threshold that is wet and salted all winter, and a seal that freezes to the floor a few times a season all shorten the life. A shaded door on a dry slab with a wipe of silicone each autumn can go much longer. The condition of the strip, rather than its age, is what to watch.
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 ResetThe morning after a thaw the opener groaned, the door stayed stuck to the icy floor for a second, then lurched up crooked.
- Garage Door Panel ReplacementThe top section has developed a bend where the opener arm pulls on it.
- Garage Door Perimeter WeatherstripThe new door went in last year and looks perfect, but the old wooden stop and its tired seal were left in place.
- Garage Door Manual Lock RepairOn the old wooden door out back, one lock bar hangs loose from a rusted guide and the other is bent at an angle, so the handle…

2021 census: what it means at the door
Every square is one home in a hundred.
- 58 in 100 homes · older homes
- 23 in 100 homes · mostly attached
- About 58% of homes in Toronto 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.
- Single-detached houses make up about 23% of homes in Toronto (2021 Census).Attached housing frequently has tandem or tight garages with limited headroom and little side room, so replacement openers and tracks are chosen to fit those dimensions. A low-headroom track kit or a wall-mounted jackshaft opener often solves what a standard unit cannot.
