Garage Door Cable Replacement
There was a sharp crack from the garage, and when you went to look the door had dropped on one side and jammed. A length of cable lies coiled on the floor by the bottom roller.

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.
In plain words
A cable visit runs in a set order. First the opener is disconnected and the door clamped so nothing can move. Then the counterbalance is unloaded so the drums, cables and bottom brackets can be handled calmly. The old cables come off, the drums and brackets are inspected, and new cables of the correct specification go on. Both sides are tensioned evenly until the door sits level, then the springs are wound back to the turns the door height calls for. Finally the door is balanced by hand, the opener reconnected and its travel and reversing checked. You are shown the finished door working before the technician leaves.
How the visit goesThe door went up as usual this morning, then stopped a third of the way with one corner higher than the other. It is wedged at an angle in the opening, the opener is humming, and nothing you press will move it.

How the visit goes

- 1
Springs and balance behind the cable
Cables only carry what the springs give them, so the springs are checked next. On a torsion system the technician looks for a gap in the coil that means a break, measures the wire and length to confirm the spring suits the door weight, and notes whether both springs on a double door match. On an extension door each spring is checked for stretch, a broken end or a missing containment cable through the middle. A weak or mismatched spring leaves one cable slack and the door heavy on one side, and if that is the story behind the cable, the spring work is explained and quoted alongside rather than left to surface later.

Setting the door level
Before any spring tension returns, both cables are brought to the same tension. The technician rotates each drum until the slack is gone and the cable is snug in its groove, then tightens the set screws onto the shaft, often onto a small flat so the drum cannot creep. A level on the top section confirms the door sits square in the opening, and the gap under the bottom seal is checked along its length. If one corner sits high, the drum on that side is eased and reset. This is the moment that decides whether the door will run straight for years, so it is not hurried.

Checking the balance yourself, safely
You can confirm the door is still balanced any time without touching a spring or cable. With the door closed, pull the opener's release cord so the trolley disconnects, then lift the door by its handle or a safe gripping point to about waist height and let go gently. A balanced door should not lift or fall far on its own; a little slow drift is normal, and what calls for a technician is rapid movement, a heavy feel, binding in the track, or a result outside the manufacturer's balance instructions, not drift alone. Reconnect the opener as the manual describes, usually by running it once. Doing this each season catches wear early and keeps the opener working lightly.

What affects the quote
- 1
Opener adjustment afterwards
A newly balanced door often needs the opener's travel limits and force settings reset and its reversing tested. That short adjustment is named in the quote when it is needed.
- 2
Torsion or extension system
A torsion door with drums and an extension door with pulleys are different jobs with different parts, and the counterbalance type is the first thing that shapes the quote.

Drums that need replacing
Worn grooves, a cracked slot or a drum that has spun on the shaft mean a new pair of drums, which adds parts and a little time to the same visit.

Garage Door Cable Replacement: questions
What happens during the visit?
The opener is disconnected and the door clamped. The technician identifies the counterbalance type, inspects both cables, the drums, brackets, rollers, track and springs, and explains what is found. The springs are unloaded, the old cables removed, new ones fitted and set so the door is level, and the springs wound back. The door is then balanced by hand, the opener reconnected and its safety features tested while you watch.
Does the new cable have to match the old one exactly?
It has to match the door, which may not be the same thing if the old cable was wrong. Length is set by the door height, the drum profile and the lift type; diameter and construction by the door's weight. A cable that is a little long overlaps on the drum and wears; one that is short leaves the door out of level. The technician measures the door and the drum rather than trusting the old cable.
Why should the bottom brackets never be loosened by hand?
The bottom bracket is where the cable attaches, so whenever the springs are wound it carries a share of the door's weight as tension. Loosening it while the counterbalance is loaded releases that tension all at once. Many manufacturers now fit tamper-resistant fasteners for this reason. The technician unloads the springs first, after which the bracket is just a piece of hardware to unbolt and replace.

What the census means at the door
47%
Homes of every age. About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.
A blend of older and newer homes usually means a blend of expectations too: keeping an original door running as long as sensible, or bringing a builder-grade door up to a quieter standard. Both are worthwhile, and the choice is explained at the door with the options side by side.
50%
A mix of homes. Single-detached houses make up about 50% of homes in Burlington (2021 Census).
Where housing is mixed, the doors are mixed as well: wide insulated doubles, narrow singles in rows and the occasional rolling door on a small commercial unit at the corner. Spring type, cable length and opener strength are matched to each door individually.
