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.

Scene 1
On a torsion door the cable drum is where most trouble starts or shows. The technician checks that each drum is tight on the shaft and that its set screws have not loosened and let it creep, which shortens the effective cable on that side. The groove is inspected for wear ridges, cracks and burrs that would chew through a new cable, and the slot that holds the cable stop is checked for damage. Where the old cable jumped its groove, the drum is examined for the mark it left and for whether the drum or an obstruction under the door was the cause. A worn drum is replaced with its mate.
Scene 2
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.
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 quoteBroughdale Garage Door Specialists

The drum is the grooved wheel on each end of the torsion shaft that the cable winds onto as the door opens. Its grooves guide the cable in a single layer and its shape sets how the door is balanced through its travel. A drum is replaced when the grooves are worn or cracked, the cable slot is damaged, or it has spun on the shaft and scored it. Drums are changed in pairs.
Yes, and both cause trouble. A cable that is too long runs out of drum groove and starts a second layer over the first, which wears it and throws the balance off near the top of travel. A cable that is too short leaves the door hanging out of level or the drum without a secure wrap. The correct length comes from the door height, the drum and the lift type, so the technician measures rather than guesses.
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.
