Garage Door Balance Adjustment
With the door closed, daylight shows under one bottom corner and the seal is squashed flat at the other. As it rises, the left side leads by an inch or two, and the top section twists slightly as it turns into the horizontal track.

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.
In plain words
An opener is designed to move a door that is already balanced, and every safety feature in it assumes that. The force it applies is limited so the door will stop and reverse when it meets something, and that limit only makes sense when the door is close to weightless. When springs lose tension, the opener has to lift real weight, its motor and gears work harder, and it may reverse or stall for no obvious reason. A balance adjustment puts the weight back on the springs where it belongs, so the opener can return to the light duty it was built for and its reversing behaviour is dependable again.
How the visit goesSomeone replaced the springs a while back and the door has bounced at the top ever since. It slams open against the stops, then creeps down a few inches, and the opener trolley rattles because the door is pushing where it should be resting.

How the visit goes
- 1
Cables, drums and whether the door sits level
A door that is out of level is usually a cable story rather than a spring story. The technician checks that each cable wraps its drum in a single neat layer with the same number of wraps on both sides, that the drum set screws are tight on the shaft, and that neither cable is frayed or rusting at the bottom bracket. A tape across the bottom of the door in the closed position shows whether one corner sits high. If it does, the cables are reset on the drums so the door is level before spring tension is judged, because a crooked door binds in its track and feels heavy regardless of how the springs are wound.

Adjusting extension springs at the hook
On an extension system the door is opened fully and clamped so each spring hangs slack, and the tension is changed by moving the S-hook or the cable clip to a different hole in the track hanger, or by shortening the cable at the clip. A hole further back stretches the spring more when the door closes and adds lift; a hole further forward reduces it. Both sides are moved the same amount so the door stays level, and the pulleys and containment cables are checked as the hooks are reset. The clamps come off and the door is tested by hand at several heights, then adjusted again if needed.

Keeping the opener honest
A balanced door lets the opener's safety settings stay at sensible values, and it is worth keeping them there. If the door ever starts to reverse for no reason or struggles to lift, resist the temptation to turn the force up on the motor; that hides a door that has grown heavy again and takes the entrapment protection out of its proper range. Instead, release the door and try the hand test. If it no longer holds, the springs want attention, and a balance adjustment puts the weight back on them so the opener can remain at the gentle settings it was left with.

What affects the quote
- 1
Commercial or oversized doors
Doors wider or heavier than a standard residential opening use heavier springs, sometimes several on one shaft, and take longer to wind and test, which the quote reflects.
- 2
Door height and lift type
Taller doors and high-lift or vertical-lift hardware carry more spring turns and different drums, so setting and testing them takes longer than a standard seven-foot door.
- 3
Condition of cables and drums
Cables that are fraying or drums with worn grooves found during the check are recommended for replacement while the system is being set, and quoted as their own items.

Garage Door Balance Adjustment: questions
How is door balance tested?
With the door closed, the opener is released so the door is free. It is lifted by hand to about a metre, then to fully open, and let go at each point. A door in balance holds its position; one that rises on its own is over-tensioned and one that drops is under-tensioned. The door should also move freely and no faster than the hand pushing it.
Why does my door drift upward when I let go of it?
Too much spring tension. The springs are pulling harder than the door weighs, so at rest they win and the door climbs. This often follows a spring replacement wound a turn too far, or a door that lost weight when heavy panels were swapped for lighter ones. Releasing a quarter turn or two, tested after each, brings it back to holding still.
What is the difference between balancing a torsion door and an extension-spring door?
A torsion door has springs on a shaft above the opening, and tension is changed by winding the springs with steel bars, a quarter turn at a time. An extension door has springs along the tracks, and tension is changed by moving the hook or cable clip to a different position with the door open and clamped. The hand test that proves the result is the same for both.

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.
