Garage Door Cable Replacement

Someone left the snow shovel leaning in the opening and the door came down on it. Now a loop of steel cable hangs loose beside the track and the door refuses to close the last few inches.

In plain words

Which counterbalance your door has shapes the job. Torsion doors carry a spring on a shaft above the opening, and the cables wind onto grooved drums at each end; the technician winds the spring down with steel bars, swaps the cables, sets the drums and winds it back up. Extension doors, common on older detached garages, run the cables over pulleys beside the horizontal tracks with a spring stretched behind each; here the door is opened and clamped so the springs relax, then the cable is threaded, adjusted at its clip and checked against its containment cable. Either way, the service ends with a balanced door.

The call
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.

How the visit goes

  1. Scene 1

    Both cables, side by side

    Both cables are examined even when only one has failed, because they are the same age and have made the same trips. The technician looks along each for broken wires, thinning near the bottom loop, rust bloom, kinks, and flattened spots where the cable has rubbed. The ends get particular attention: the swaged stop that seats in the drum and the loop or ferrule that rides on the bottom bracket pin. The two are compared for length as well, since a stretched or slipped cable shows as one corner of the door sitting higher. This comparison decides what is fitted and explains any crookedness you have noticed.

  2. Scene 2

    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.

  3. Scene 3

    The record of what was fitted

    Before leaving, the technician tells you what went on the door: the cable length and diameter, whether the drums or bottom brackets were renewed, the type of lift hardware, and how many turns the springs carry. It is worth writing this inside the cover of the door manual or on a card taped near the opener, because the next technician, or the same one years from now, can then match parts without measuring everything from scratch. If the springs were left in place, their age and wire size go on the same note so the timing of their eventual replacement is easy to plan.

What shapes the quoteDynes Garage Door Experts

Door weight and width
A heavy insulated double door needs a heavier cable and sometimes different drums than a light single, and the springs behind it take longer to wind down and back up.
Oversized, commercial or high-lift doors
Doors taller or wider than a standard residential opening, or fitted with high-lift hardware, use heavier cables and drums and take longer to set up, which the quote reflects.
Access to the spring shaft
Shelving, storage or a low ceiling around the torsion shaft and drums slows the work. Clearing the area beforehand or a tighter working space both affect the time quoted.

The questions that come up

What stops the door from falling if a cable lets go?

It depends, and not reliably. The other cable and its spring may hold that corner so the door tips and wedges in the track rather than falling square, and the rollers binding can add some resistance, but neither is dependable: the door can still drop unexpectedly on the failed side. Some doors also carry a broken-cable device on the bottom bracket that grips the track if a cable fails. Because the door may not be held at all, the technician clamps and supports it before doing anything else.

Why did the cable come off the drum?

A cable leaves its drum when it goes slack for a moment while the drum keeps turning. The usual reasons are the door closing onto an object or a ridge of ice so the bottom stops early, a spring that has lost tension or broken, or a drum whose set screws let it slip on the shaft. The technician finds which of these happened and corrects it so the new cable stays seated.

Should both cables be replaced when only one has failed?

Yes, as a rule. The two cables were fitted together, have flexed around their drums the same number of times and have sat in the same slush, so the survivor is close to the end of its life. A new cable beside a stretched one also makes it harder to set the door level. Two matched cables give an even lift and one visit instead of two.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 47 in 100 homes · mixed ages
  • About 47% of homes in Burlington were built in 1980 or earlier, according to the 2021 Census.A mixed-age neighbourhood is where retrofits are most common: safety cables added to extension springs, a torsion conversion on an older door, insulated panels replacing a hollow door, or a quieter belt opener under a newly finished room above the garage. Each is a routine job for us.
  • Single-detached houses make up about 50% of homes in Burlington (2021 Census).Where houses and attached homes sit together, the shared garage door on a small condo building may be a commercial operator on a heavy door, while the house next door runs a light residential unit. We service both types and carry parts for each.
