Garage door parts we carry and fit

Almost every garage door fault is a part, and most of them are small. What makes them a service call rather than a hardware store trip is that several of them are matched to the specific door, and two of them are under enough tension to hurt somebody.

The parts that carry the weight

Springs. Torsion springs are specified by wire size, inside diameter and length, and that combination is what makes the door balance. Extension springs are rated by the weight they lift. Neither is a generic part, and neither is a homeowner job.

Cables, drums and the shaft. The cable length and the drum size have to suit the door height, and the two sides have to be set equal or the door hangs crooked. Bearing plates and the centre bearing wear quietly and are usually replaced at the same time as the springs, because everything is already apart.

Bottom brackets. These are under full cable tension and are the one bracket on a door that must never be unbolted while the springs are wound.

The parts that make it run

Rollers. Steel rollers are the cheap original fitment and they get noisy as the bearings go. Nylon rollers with sealed bearings run quieter and last longer, and they are the single most noticeable upgrade on an otherwise sound door.

Hinges, numbered by position up the door, and the end hinges that carry the roller stems. Track, brackets and struts. None of these is exotic, but the sizes matter and a mismatched hinge changes how the sections meet.

The parts that seal it

The bottom seal in its retainer is what keeps meltwater, grit and mice out, and it is the part that perishes fastest because it takes the ice. Rubber lasts better than PVC through freeze and thaw. Perimeter stop moulding seals the sides and the head, and a worn one is usually why a closed door still whistles.

Opener parts

Opener parts: gear kits, sprockets, chains, belts, trolleys, rails, logic boards, capacitors, limit switches, safety eyes, wall consoles, remotes and keypads. Most of these are replaceable individually, which is why an opener with a single failure is usually worth repairing.

What we stock

The truck carries torsion and extension springs, cables, rollers, hinges, drums and opener gear kits, which covers most of what a service call turns out to need. Anything model-specific is identified on site and ordered against the actual door rather than guessed from a photograph.
