- The call
- Standing inside with the door closed, you notice the cable on the right side near the floor has gone fuzzy. A handful of broken wires stick out like a bottle brush and the steel underneath is brown.

What you get back is a door that behaves as it did when it was new. Both corners rise and fall together, the bottom seal meets the floor along its whole length, and the opener runs without straining or reversing. Because the cables were set to the same length and the springs re-tensioned to match, the door can be lifted by hand with light effort and will hold steady halfway up. You also leave with a note of the cable specification, drum type and spring turns, which makes any future service simpler, and a few habits that keep the new cables in good shape.

Scene 1
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.
Scene 2
Each drum's set screws are backed off so the drum spins freely on the shaft, and the old cable is unwound from its groove and the stop slipped out of its slot. At the floor, the loop is lifted off the bottom bracket pin, or the clevis pin and cotter pin are withdrawn where the door uses them. The old cable is kept for a moment to measure against its replacement and to show you the wear that caused the call. On an extension door the cable comes off its pulleys and the adjusting clip at the track hanger. Both sides are stripped before anything new goes on.
Scene 3
A few minutes with a can of garage-door lubricant twice a year keeps the whole system easy on the new cables. Spray the torsion spring lightly along its length, the hinge pins, the roller stems and bearings, and the bottom bracket pins, then run the door a few times to spread it. A light mist on the cables themselves slows rust; heavy grease is avoided because it holds grit and moisture. The tracks are left dry and simply wiped clean, since lubricant there collects dirt and lets rollers slide instead of roll. Silicone or a lithium spray made for doors is the right product.
What shapes the quoteDownsview Door Specialists
FeesSame any hour
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.
A lift cable does the work: it connects the door's bottom corner to the spring system and carries the door's weight. A safety or containment cable does no lifting at all. It runs through the middle of an extension spring and is anchored at both ends so that if the spring breaks, the pieces stay put. Torsion springs sit on a shaft and do not need one.
Yes. The visit ends with the door balanced by hand, run through full cycles and the opener reconnected and tested, so it is ready for normal use the moment the technician packs up. There is no settling period for cables. It is a good idea to watch the first few openings yourself to get a sense of how a level, balanced door sounds, so you notice any change later.
