- The call
- After the power came back you pulled the red cord to get the car out. Since reconnecting, the door stops short of the floor, and no amount of turning the limit adjustment brings it the rest of the way down.
There is a new squeal from the front of the rail, up near the header, on every cycle. The belt has started tracking to one side and its edge is fuzzy where it has been rubbing.
In plain words
A stalled belt drive is often a trolley problem, not a belt problem. The trolley rides the rail in two halves: an outer part linked to the door arm and an inner part gripped by the belt. Pulling the red cord parts them so the door can be lifted by hand; running the operator, or a second pull, locks them again. When the release lever sticks, the housing cracks or the halves refuse to re-engage, the motor moves the belt and nothing else. Repair means freeing or replacing the trolley, checking the belt for damage from the drag, and confirming the inner half is in step with the motor.

How the visit goes
Scene 1
What the operator thinks it is doing
Before any part is changed, the technician runs the door from the wall control and watches what the operator thinks it is doing. Does it stop short of the floor and reverse, or drive the trolley into the stop bolt? Does the top section stop clear of the header bracket? Does the door come back up on meeting a 2x4 laid flat and when the beam near the floor is broken? The answers separate a drive fault from a settings fault, and settings will be relearned once the belt work is done anyway. The wall control height, the photo-eye height and where the red handle hangs are noted at the same time.
Scene 2
Re-tensioning a belt that has stretched
With the operator unplugged and the trolley released from the door, the technician turns the square nut on the inner trolley a little at a time, drawing the belt up until the tension spring reaches the length the maker specifies. Each turn lifts the belt slightly. They press the belt at mid-span to feel for the small give that means it is neither slack nor strained, then reconnect the trolley and run the door by motor, listening at the sprocket for the rattle that says the belt is still loose or has gone too tight. A belt that will not reach its spring length with the adjuster at its limit has stretched too far and is replaced instead.
Scene 3
The hush is back
What you notice first is the sound, or the lack of it. A belt drive in good order starts softly, hums along the rail and eases to a stop, and after the repair it should sound the way it did the week it was installed. The clack of a loose belt, the squeal of a dry pulley and the growl of a stripped gear are gone because their causes are gone, not masked. Listen for that baseline over the next few weeks; a new noise arriving is the earliest warning you will get, and a belt drive tends to announce trouble months before it stops. A short call at that stage is a small adjustment.

What shapes the quoteApplewood Hills Garage Door Co.
- Height of the ceiling
- Where the operator hangs under a tall or vaulted ceiling, the sprocket and idler are reached from taller ladders and the work at the head takes longer.
- A second operator on the same property
- Where a double garage has two belt drives, or a workshop has its own, both can be looked at in one trip, and the quote shows the two repairs on a single visit.
- Idler pulley
- A squealing or wandering pulley at the header end of the rail is a separate part and a few extra minutes with the belt slack, quoted only when the inspection finds it.

What people ask us
Does the trolley need replacing when the belt does?
Not usually. The trolley is checked while the belt is off: its halves should part with the release cord and lock again, the housing should be free of cracks and it should ride the rail without play. A trolley that passes those checks stays and simply receives the new belt and a fresh clip. One that sticks or rattles is replaced in the same visit.
How long should a belt last once repaired?
A belt's life is counted in cycles and years, and on a balanced door with the rail straight and the tension right it runs for many years. What shortens it is a heavy door, an over-tight adjustment, a bent rail rubbing one edge, or grease on the rubber. Keep the door balanced and lubricated, the belt dry, and glance along the rail a few times a year.
Will my remotes and keypad still work afterwards?
Yes. Belt, trolley and pulley work happens on the rail and leaves the operator's memory untouched. Replacing the gear at the motor head means opening the head unit, and on some models that is a good moment to confirm every remote, the keypad and any in-car buttons afterwards. The technician tests each before leaving and re-teaches any that need it.

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 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 37% of homes in Mississauga (2021 Census).Townhouse rows generally have a narrow single door on each unit, with shared walls on both sides. Noise from a chain opener or dry rollers carries straight into the neighbour's home, so quiet belt-drive openers and nylon rollers are a popular and considerate choice here.
