Garage Door Cable Replacement
The car bumper kissed the door on the way in. The bottom panel has a dent, the bracket in that corner sits crooked, and the cable on that side has jumped and gone slack, so the door reverses every time it tries to close.

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
Two steel cables do the lifting on a sectional garage door. Each runs from a bracket at a bottom corner up to the counterbalance, and the springs pull on the door through them. Cable replacement renews that link. The technician secures the door, takes the tension off the springs, removes the worn or displaced cables, fits new ones matched to the door's height and weight, and re-tensions everything so both corners rise together. The result is a door that travels level again, closes flush to the floor, and asks the opener for the modest effort it was designed to give.
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.

Extension-spring doors: pulleys, clips and containment
On a door with springs along the tracks, the new cable is threaded from the bottom bracket up over the pulley at the front of the horizontal track, back to the pulley on the end of the spring, and forward to the adjusting clip on the track hanger. The technician replaces a pulley whose wheel is grooved or whose bearing has seized, since that is often what wore the cable, and checks the S-hooks and sheave forks. Each side is set to the same clip position so the door hangs level. A containment cable is confirmed through the centre of each spring and added if the door was never fitted with one.

A clear threshold
Most cables that jump their drums do so because the door came down on something. Keep the opening clear of bins, bikes and the snow shovel, and in winter clear the ridge of packed snow and ice that forms at the threshold before running the door. If the door does meet an obstruction and stops, leave it where it is rather than pressing the button again, since a second attempt is what turns a slack cable into a tangled one. The photo eyes near the floor should be clean and aligned so they catch anything in the path; a wipe with a soft cloth each season keeps them working.

What affects the quote
- 1
Extension-spring pulleys and containment cables
On an extension door, pulleys with grooved wheels or seized bearings are replaced with the cable, and a containment cable is added where one is missing. Each is a small parts line.

Whether a matching part has to be special-ordered
Most drums, brackets and cable sizes are common stock, but an older or uncommon door sometimes needs a part matched to its exact dimensions. When that happens the technician identifies it on the first visit and arranges the part before the return trip.

Corrosion and seized fasteners
Set screws and bracket bolts that have rusted solid take time to free or cut, and badly corroded hardware is replaced rather than reused, which shows in the parts list.

Garage Door Cable Replacement: questions
How do I tell a cable problem from a spring problem?
Look above the door with it closed. A torsion spring that has broken shows a clear gap in the coil, and both cables usually go slack together because nothing is turning the shaft. A cable problem tends to show on one side only: a frayed length, a coil of loose cable, or one corner sitting higher. Either way the technician inspects both, since a weak spring is a common reason a cable fails.
Should I keep using the opener until the technician arrives?
It is better to leave the door where it is and use another way in and out. Running the opener against a crooked or cable-slack door tends to tangle the cable further, twist the top section and knock the door out of its track, which adds to the repair. Pull nothing and adjust nothing; simply keep the opening clear and let the technician take it from there.
Why is the door sitting crooked in the opening?
Each corner of the door is held by its own cable. When one cable stretches, slips its drum or breaks, that corner loses its lift and drops while the other stays up, so the door tips and usually wedges against the track. Setting both cables to the same length and tension is part of every cable replacement, and it is what brings the door back level.

What the census means at the door
38%
Homes of every age. About 38% of homes in King were built in 1980 or earlier, according to the 2021 Census.
In a mixed neighbourhood, some garages are detached with plenty of side room and others are tucked under a bedroom with little headroom, so opener and spring choices vary from house to house. Measuring at the door, rather than assuming, is how the right hardware is chosen.
87%
Mostly houses. Single-detached houses make up about 87% of homes in King (2021 Census).
In a neighbourhood of houses, each garage door is chosen by the household, so styles vary from one driveway to the next. When it is time for a new door, homeowners pick panel design, windows, colour and insulation freely, and we bring samples to compare against the siding.
