You heard a sharp bang from the garage, and now the opener hums for a second and gives up. The door lifts a few centimetres at most, then settles back down as if something very heavy is holding it in place.
The finished result is a door that behaves the way a good garage door should: it lifts by hand with light effort, stays where you leave it at mid-height, closes softly and lets the opener run with little strain. Reaching that point involves measuring the door, choosing a matched spring, winding it to the correct turns and testing the balance through the full travel. The technician then runs the opener's reversal test and lubricates the moving parts. You are left with a record of the spring installed, so future service starts from known specifications.

Torsion Spring Replacement · Fisherville
Scene 1
Doors are set up in several ways, and the replacement has to match. The technician notes whether there is one spring or two, whether the shaft is a single piece or two halves joined by a coupler, and what the shaft diameter is. Drum type is read from the drums themselves: standard-lift drums for a normal ceiling, high-lift or vertical-lift drums where the door rises well above the opening, or a rear-mounted assembly in a low-headroom garage. Track radius and headroom are measured because they change how many turns the spring needs and which drums it must work with.
Scene 2
With the door clamped and the opener disconnected, the technician releases any tension left in an intact spring, loosens the drum set screws and slides the drums inward, then removes the old spring from the shaft. Bearings are inspected while the shaft is free. The new spring goes on with its stationary cone bolted to the centre bracket and the winding cone facing the drum. Drums are refitted, cables seated, the shaft levelled and cable tension evened on both sides. Winding follows, then the set screws are seated and the clamps come off for a balance check. Each stage is done deliberately and in order.
Scene 3
A healthy spring system is quiet and even, so changes stand out. Listen for a new grinding or popping sound as the door moves, watch that both sides of the door rise together, and look at the cables for fraying or a loop that has left the drum groove. Rust streaks below the shaft, a door that takes noticeably more effort by hand, or an opener that starts to strain are all early indicators that something in the balance system wants attention. Catching these early keeps repairs small and lets the household plan a visit rather than face a stuck door.

A picture of the full spring assembly above the door, showing the centre bracket, both drums and how many springs there are, tells the technician a great deal. Add a close shot of the broken spring gap and any tag or colour marking on the cones, a photo of the cables at the bottom brackets, and one of the opener. These help confirm the door's configuration so the right springs and hardware are on the truck.
Most residential replacements are completed in one visit. Securing the door, measuring, removing the old spring, fitting and winding the new one, balancing and testing the opener typically takes an hour or two, longer if bearings, cables or a bent top section are also being dealt with. The technician confirms the scope after the first checks, so you know what the visit involves before the work starts.
Low-headroom garages use a different arrangement: the spring assembly may be mounted at the rear of the horizontal tracks, or special low-headroom drums and track bring the door up with less clearance. Replacement follows the same principles, but the drums, cable routing and turn count differ. The technician identifies the system on arrival and brings hardware that suits it, so the door balances correctly in the space available.
