Garage Door Tune-Up
Halfway up, the door shudders. The sections seem to catch for a moment, the whole assembly shakes, then it carries on as if nothing happened.

The visit follows a set order. First the technician watches a full cycle, up and down, from a safe distance, noting where the noise, shaking or hesitation lives. Then the door is closed and inspected hardware by hardware, from the bottom brackets to the torsion shaft. The manual release is pulled and the door is lifted by hand to feel the balance. Only then does the work start: fasteners, lubrication, opener adjustments and sensor alignment. A second cycle and the reversal tests close the visit, and the difference between the first run and the last is the measure of the tune-up.
How the visit goesOn windy nights the door rattles in its frame, there is a line of daylight along one side, and the bottom seal has gone hard and flat. Leaves and fine snow drift in underneath and the garage never seems to hold its temperature.

How the visit goes

- 1
Feeling the balance by hand
The door is disconnected from the opener with the red release handle, and the technician lifts it by hand, gripping only the handles or a safe edge. A properly balanced door rises with modest effort, stays fully open on its own and holds still when left about a metre off the floor. A door that sinks back down, or that takes real strength to raise, has springs that have lost tension and an opener that has been carrying weight it was not designed for. This check takes a minute and decides more than any other: it tells the technician whether the tune-up can proceed as maintenance or whether spring work needs to be quoted first.

Cleaning and aligning the photo-eyes
Photo-eyes work only when each sensor can see the other. The lenses are wiped clean of dust, cobwebs and salt film, the brackets are checked for the bends that a bin or a bicycle tire leaves behind, and the pair are aligned until both indicator lights hold steady. Height is confirmed at no more than about 15 centimetres off the floor, and the wiring is traced back to the opener head for a chafed or loose connection. Where low sun fools a sensor at a certain hour, a small shade or swapping the two units settles it. Once aligned, the beam is tested with the door closing to confirm it reverses and returns fully open.

Knowing what to listen for next
Part of the handover is a short lesson in the door's language, so the next change registers. A squeak returning means the hinge pins want lubricant. A new rattle at the top of travel means a screw is loosening and is worth a look. A door that starts to sink when lifted by hand is springs losing tension. A loud bang from the garage with the door then feeling very heavy is a broken spring, and the door stays closed until it is replaced. A door that reverses on its own with no obstruction is a sensor or force issue. With these signs in mind you can describe a problem precisely and decide whether it needs a call.

What affects the quote
- 1
Photo-eye and wiring work
Cleaning and realigning sensors is routine. A bent bracket, a chafed wire or a sensor that has failed means a part or a rewire, which is named separately.
- 2
Track alignment
Tightening track bolts is included. A track that has been pulled out of line or dented by a vehicle needs straightening or a section replaced, and that is quoted as its own repair.
- 3
Age of the door and opener
Older hardware may need fasteners in sizes no longer standard, and an opener without photo-eyes prompts a conversation about entrapment protection that is quoted separately from the tune-up.

Garage Door Tune-Up: questions
What should I do if the bottom seal freezes to the floor?
Do not keep pressing the button; the opener can tear the seal or pull the top section out of shape. Free the seal by clearing the ice along the threshold, with warm water poured on the concrete rather than the door, or by working a plastic scraper along the seal. Then treat the seal with a silicone spray. Keeping snow and meltwater cleared from the threshold and keeping the seal flexible with silicone prevents most repeats.
What does a garage door tune-up actually include?
A full cycle observed before any work, a hands-on inspection of hinges, rollers, tracks, springs, cables, drums, brackets and the opener's attachments, tightening of the accessible fasteners, lubrication of the moving points with a garage door lubricant, a balance check with the door disconnected from the opener, adjustment of the opener's travel and force, cleaning and alignment of the photo-eyes, both reversal tests, a look at the seals, and a written record of the findings.
Will the tune-up include replacing worn parts?
Small wear items found on the day, such as a roller or a hinge on a middle section, a bottom seal or a few fasteners, can often be replaced during the visit if you agree and the part is on the truck. Larger items, including springs, cables, drums, bottom brackets, a bent track or an opener gear, are written up as separate repairs with their own quote so you can decide with the facts in hand rather than under a raised ladder.

What the census means at the door
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.
