A torsion spring failing is unmistakable: one hard crack from the garage, and afterwards the door is either immovable or far heavier than it has any right to be. The opener will pull, labour and give up, because it was built to guide a door that its springs are already holding, not to lift one on its own.
This is the single most frequent call we take out of Compton, and there is a pattern behind a good share of them that is specific to this city's garages. The spring did not simply get old. It was doing more work than it was ever specified to do, because the door in front of it had grown.
A wider door on the narrow door's counterbalance
When an opening in one of these garages is widened, the door gets wider and heavier — sometimes considerably heavier, because a wider door usually also means a longer, deeper section profile and often an insulated one where the original was a light single-skin or a one-piece. The counterbalance has to grow with it. A torsion system lifts by converting stored torque into cable tension over the drums, so a heavier door needs more torque, which means more wire, a longer spring body, or a heavier wire diameter, and the shaft, the drums and the cable lengths all have to suit the new geometry. What we find on a large number of widened openings here is that only some of that happened. The door was replaced properly and the counterbalance was carried over, or partly carried over — the original shaft and drums retained, a spring added alongside the old one rather than the pair being specified afresh, or a single spring of the previous size fitted to a door that now needs meaningfully more lift.
A system in that state does not fail immediately, which is precisely why it is common. It works, in the sense that the door goes up and down, and nobody has reason to question it. What is actually happening is that the spring is being wound closer to its working limit on every cycle and is doing so on a duty cycle that was never modelled for the load. Rated cycle life falls away sharply under those conditions. The owner experiences a spring that broke earlier than they expected on a door that seemed fine, and concludes they were sold a bad spring, when what they had was a correct spring for a door that no longer exists.
So we specify from the door that is hanging there now, measured, rather than from what came off. We weigh the door with the tension released, cross-check the weight against the travel height and the drum diameter, and derive wire diameter, inside diameter and wound length from that. We also check that the shaft and the drums actually suit the door's width and lift — carrying over drums sized for a narrower door leaves the cable stacking wrongly and puts an uneven pull on the two bottom fixtures, which is one of the reasons a widened door will show wear on one cable and not the other. Measuring the broken spring is not a substitute for any of this, because a spring that has failed has already stretched and its dimensions are no longer the ones it was made to.
The anchor is half of the spring system
Everything a wound torsion spring does is reacted through the centre bearing plate and the anchor bracket, and everything those do is transmitted into whatever is above the opening. On an unaltered garage that is the original header on its original bearings and the question is simply whether the timber is sound. On a widened opening in this city it is a different question, because the material behind that plate arrived during the alteration. It might be a properly sized member bearing squarely on solid trimmers, which is ideal. It might be a nailer that somebody added so there would be something to screw a plate to, which is not.
This is the check we will not skip, and it is worth explaining why it matters more than it sounds. A spring anchor that is slowly working loose does not announce itself. It elongates its fixing holes a fraction at a time, the plate creeps and leaves a shadow line on the surface behind it, the shaft runs marginally out of true, the bearing starts to wear on one side, and the spring's anchor end takes cyclic movement it was never meant to see. By the time it is visible from the floor, the situation is that a component storing a serious amount of energy is held by fixings that are no longer fully seated. Winding a fresh spring onto that arrangement without looking at it is not a repair, it is a postponement.
Where the material will carry the load, we fix into it correctly and get on with the job. Where it will not, the answer is to spread the load onto structure that can — a backing plate spanning to sound framing, fixings relocated out of a cluster of old holes, or in the worst cases a recommendation that the head itself needs proper attention before a counterbalance goes back on it. That last one goes on the written estimate as its own line, in advance, because it is the sort of thing nobody wants to hear about for the first time with the door already off.
While you are waiting: stop pressing the button
The most useful thing you can do between the bang and our arrival is nothing. Specifically, stop operating the opener. That motor is designed to guide a counterbalanced door, and running it against a door whose spring has failed strips the nylon drive gear, can damage the logic board, and reliably converts a spring job into a spring and opener job for no benefit whatsoever. A door that is already shut should stay shut, with the car left on the driveway for the night. A door that stopped open should stay open, with the floor beneath it kept clear.
We rarely tell people not to attempt something, and this is one of the few times we do. A wound torsion spring holds a great deal of energy and it is released in a controlled sequence using correctly sized winding bars. Nearly every serious injury in this trade comes from improvised bars in the winding cone — a screwdriver shaft, a piece of reinforcing bar, anything roughly the right diameter. Being careful is not the variable. Having the right bars and the right procedure is.
Two practical points on top of that. Where a door runs two springs and one has broken, we will recommend replacing both every time, and the reasoning is arithmetic rather than sales: they were fitted together, they have carried an identical cycle count, and the one still intact is not healthy, it is simply next. On a widened opening there is an additional reason, which is that the pair has to be specified together against the current door weight, and matching a new spring to a survivor that was sized for a different door reproduces the original problem. And if the door has stopped part way, keep everyone and every vehicle out from under it — whatever is holding it up is holding it unevenly.
Spring Repair in Compton — FAQs
- The honest test is a hand test with the opener disconnected. Pull the manual release, lift the door to about waist height and let go. A correctly counterbalanced door will stay roughly where you left it. If it drops, the springs are giving less lift than the door weighs. If it climbs, there is more tension than the door needs. On any garage where the opening or the door has been changed at some point, that test is worth doing occasionally, because it is the quickest way to notice a mismatch before it becomes a failure.
- It generally means a larger specification — more wire, a longer body, sometimes a pair where there was one — because the counterbalance has to match the actual weight of the door. What it should not mean is a surprise. The weight is measured at the visit, the specification follows from that measurement, and both appear on the written estimate before anything is ordered or wound. If part of the cost is anchorage work rather than the spring itself, that is itemised separately so you can see exactly what you are paying for.
- Usually yes. The vans carry torsion springs across the range of wire sizes and lengths that this area's door widths call for, along with drums, bearings, bearing plates, shafts and cables, and they are loaded from our own parts room rather than from a supplier order. Where a door turns out to need something outside that range, or where the anchorage needs work before a spring can safely be wound, you will hear that at the estimate along with a real date rather than a vague reassurance.
