The door goes up perfectly. Coming down is the trouble: partway to the floor it stops, climbs back to the top, and the light on the opener blinks at you. The only way to close it is to stand inside holding the wall button the whole way down.

Lift cables carry the whole weight of the door to the drums. When a strand breaks or the cable rusts at the bottom bracket, it is time to replace the pair. We do that with the springs released, then set the door level and retension.

The fix, explained · Markham
The fix
Torsion spring replacement is really a service on the whole balance system. The spring sits on a shaft that turns in a centre bearing and two end bearings, drives a pair of cable drums, and lifts the door through two steel cables.
Until then
When a spring breaks, the safe approach for the household is to leave the door where it is, keep people and vehicles clear, and avoid running the opener, which can damage the top section, the trolley or the gear drive.
Pull the manual release only when the door is fully closed unless a technician asks otherwise; a door disconnected while partly open can move on its own if the springs are out of balance.

The fix
An off-track reset is the visit that puts a crooked, jammed or hanging garage door back onto its rails. Sectional doors ride on rollers inside a pair of curved steel tracks, and when a roller escapes, the door racks sideways and jams.
Until then
Never run the opener on a door that is off its track or hanging crooked; every cycle drives the racked door harder into the rails and can pull the track from the wall or tear a hinge.
Pull the manual release only when the door is fully closed unless a technician asks otherwise; a door disconnected while partly open can move on its own if the springs are out of balance.

The fix
What you get back is a door that behaves as it did when it was new. Both corners rise and fall together, the bottom seal meets the floor along its whole length, and the opener runs without straining or reversing.

The fix
What you have afterwards is a door that behaves like a much lighter object. Both corners leave the floor together, the door holds still when you stop it at waist height, and it settles onto the floor instead of slamming.

The fix
Most households meet the release for the first time in a power outage, usually in winter. The door is shut, the car is inside, and the red handle is the only way to move the door.
Until then
Pull the release with the door fully closed whenever possible, and keep the opening clear as you do.
Lift a door by its handles or the gripping points on the panel face, never at the joint between sections, which closes as the door bends around the track.
The fix
Most openers built in the last fifteen years report their own trouble. When something is wrong the head unit blinks its lights in a count, an up arrow and a down arrow flashing in a pattern, or a status light repeating a number.
Until then
Pull the release with the door fully closed whenever possible, and keep the opening clear as you do.
Never drive a vehicle at a closed door to get out; the door collapses and the stored tension in the counterbalance is released.

Doors without openers still need to lock securely. We repair slide bolts, T-handle locks and the bars that engage the track, align them so they seat without forcing, and replace worn cylinders. For doors that do have an opener, we make sure any old manual lock is disabled so it cannot jam the door mid-travel.

19%
Newer homes. About 19% of homes in Markham were built in 1980 or earlier, according to the 2021 Census.
A newer door still under its first set of springs is a good candidate for preventive work: lubricating the torsion spring, checking the cable ends at the drums and confirming balance before the spring reaches its cycle limit, so the replacement is planned rather than forced by a broken spring.
56%
A mix of homes. Single-detached houses make up about 56% of homes in Markham (2021 Census).
A mixed neighbourhood is where weatherproofing varies most. A detached garage with an old, uneven apron needs a thicker bottom seal; a newer townhouse door mostly needs a cracked section of seal replaced. We look at how each door meets its floor and fit what closes the gap.
In most cases it comes back better, because the reset includes truing the track, replacing worn rollers and correcting the misalignments that had been building unnoticed. The exception is a section creased by an impact: it may work perfectly well after the reset yet keep a visible dent, and the technician will tell you whether it is sound or worth replacing at some point. You are shown the door running before the visit ends.
That is the manual release, which disconnects the door from the opener's trolley so the door can be moved by hand. It is safe to pull when the door is fully closed, and it is the right thing to do if the opener keeps trying to move a jammed door. Avoid pulling it with the door part way open unless a technician asks you to, because an unbalanced door can move once it is freed.
Lifting a crooked door is where most injuries around this problem happen, because the springs and cables are loaded unevenly and the door can shift suddenly. Tell the technician on the phone that a vehicle is inside; getting it out is part of the plan, and the door will be supported and levelled before it is raised. A short wait is far cheaper than a bent section or a hand caught between panels.
Once or twice a year is a good rhythm, with autumn the most useful time because cold thickens grease. Use a garage-door lubricant, typically a silicone or lithium spray, applied along the coils so it works between them as the door cycles. Hinges, roller bearings and the end bearings benefit from the same treatment. Keep the track itself dry, since lubricant there gathers grit and slows the rollers.
