A torsion spring that truly snaps announces itself with a single flat crack from the garage, loud enough that most people go looking for whatever heavy thing has fallen. After it, the door is either locked solid or dismayingly heavy, and the opener will heave at it and give up — it was only ever meant to steer a door the spring was already carrying, never to lift the whole dead weight.
But beside periodic overflight the more common spring complaint is not a break at all, and it is worth understanding before you book anyone. It is a sound, correctly specified spring that has quietly lost its grip on the shaft, because the set screws clamping its winding cone have vibrated loose. The door leans, lifts crooked and drags one side, and everybody assumes the spring is failing. It is not. Its hold on the shaft has crept, and the fix is to reset and re-torque, not to replace.
Why a spring here loses the shaft before it loses its life
A torsion spring does not lift the door by itself; it winds up a steel shaft that runs across the opening, and the cable drums are fixed to that same shaft, so it is the shaft that actually raises the door. The spring holds onto the shaft at each end through a winding cone, and the cone is clamped to the shaft by a pair of set screws biting into the steel. That small threaded joint carries the entire wound tension of the spring. It is, in other words, a fastener under a very large and constant load — and like every other fastener on this door it is exposed to the low-frequency vibration that comes with periodic overflight.
Under that vibration the set screws creep, exactly as the lag bolts and hinge screws do, but the consequence is larger. As a cone's set screws back off, the cone begins to slip on the shaft under tension, and the spring surrenders a little of the turn it was holding. On a two-spring door the two cones almost never creep at the same rate, so the two sides fall out of synchronisation: one spring is still holding its full turns and the other has let some go. The door is now unbalanced across its width — it lifts higher on the stronger side, leans in the opening, and drags the weaker side in its track. Owners describe a door that has started going up crooked, and reach for the conclusion that a spring is on its way out.
The spring is usually fine. What has changed is its grip on the shaft, and that distinction matters because the two problems have completely different fixes and completely different costs. A creeping cone is reset true on the shaft and its set screws re-torqued to specification; a genuinely failed spring is replaced. Confusing the two is how owners get sold a pair of springs they did not need. The one thing a creeping cone must not be is ignored, because a set screw that keeps walking eventually walks all the way out, at which point the cone lets go and the spring's hold on the shaft is lost in a single instant — the same sudden loss of counterbalance as a break, arriving without the courtesy of a bang.
Resetting the cones, and when a spring genuinely needs replacing
When the springs themselves are sound, the correct work is to bring the door back into balance and see that it stays there. We wind both cones to the same set turns so the two sides share the load evenly again, seat each cone squarely on the shaft, and re-torque the set screws to the spring maker's figure rather than to feel — over-tight shears the screw or scores the shaft, under-tight is where you started. Where the cone design allows it we go the extra step of locking the set screws, because on this door plain friction is precisely what the vibration keeps defeating. Then we cycle the door and check that both sides lift together, because a door that leaves level is a door whose cones are gripping.
When a spring truly has gone — a clean gap in the coil, or one so tired it no longer holds its turns — we replace it, and we size the new one from the door, never from the wreck of the old. A broken spring has already stretched and shifted, so any measurement off it just re-enacts whatever call was made last time round. What we do instead is take the counterbalance down, weigh the door, and work the wire size, the inside diameter and the wound length back from that weight, the height it climbs and the drum fitted. On a broad opening we hang a matched pair, so the effort is split and a later failure still leaves the door half-supported rather than dropped.
Either way, the cables, drums and bearings get looked at with the springs, because a door lifting crooked for months has been loading them unevenly the whole time. A cable chafing on a drum edge, a drum carrying more than its share, a bearing whose own fixings have crept — leave any of those behind a freshly balanced door and you have booked a return visit. We reset the drums to a matched effective radius, renew any cable showing damage, and re-anchor the bearings to sound framing so the shaft runs true. Throughout, the point is that the spring is one part of a system the vibration has been working on, and putting the door right means seeing to the fixings, not just the spring.
Please leave the winding to somebody with bars
There are only a handful of jobs we would actively steer a handy homeowner away from, and winding a torsion spring is the plainest of them. A wound spring has a dangerous amount of energy stored in it, and letting that energy out safely means winding bars of the right size, used in the right order. Reach for a screwdriver, a length of rebar or an adjustable wrench in the cone instead and the injuries are the sort that do not heal. There is a wrinkle peculiar to this place on top of the usual caution: a cone whose screws have crept is no longer holding the shaft the way a sound one does, so under the bars it can move in ways you would not predict. That is grounds for keeping clear of it, not for trying your luck.
If a lost or broken spring has left the door shut, leave it shut — and whatever you do, stop hitting the button. The opener is a guide for a door the spring is holding, not a winch for a dead one; ask it to haul the full weight and you shear its gear and can lose the board with it, so now you are buying a motor as well as a spring and are no further forward. Put the car on the drive or out at the kerb rather than nose-up to a door nothing reliable is carrying, and phone us; the line is answered whatever the hour.
If the spring went while the door was up, the right move cuts against every instinct: do not go near the red cord and do not try to lower the door. With nothing counterbalancing it, the door is bearing its whole weight on its own, and releasing it from the carriage simply drops it. Leave it exactly where it stopped — up, part-way, wherever — steer cars, children and pets out from under the opening, and call. Whoever is nearest you at that hour comes out, with the bars and the parts to make it safe and set it right.
Spring Repair in Los Alamitos — FAQs
- Not necessarily, and near periodic overflight it usually is not. A door that lifts higher on one side and leans is more often a winding cone that has lost its grip on the shaft because its set screws have vibrated loose, so that one spring is holding its turns and the other has surrendered some. The springs themselves are frequently sound. We check the cones and the set screws before condemning anything, reset both sides to matched turns, and re-torque and where possible lock the screws. It would be easy to sell you springs for this, and in this city it is often the wrong repair.
- On a two-spring door, replace both. The pair have lifted the same door the same number of times, so the one still intact is not in good shape — it is just the one that has yet to let go. There is an extra reason in this city: if a crept cone has had the door going up lopsided, the two have not even been splitting the load evenly, and the one that broke may have been shouldering more than its share for months. Fit one alone and you have a lopsided door today and a second call-out, with its own labour, not far behind. We put in a matched pair and set both cones true.
- Largely, yes, and it is the right question to ask. Resetting the cones true and re-torquing the set screws to spec is the first half; the second is not leaning on friction alone, since friction is exactly what the vibration keeps lifting. Where the cone design permits, we lock the set screws so they cannot walk out under the next season of overflight, and we show you the couple of fixings on the door worth a glance once a year. A cone that is reset and locked is far less likely to be back on our list than one merely nipped up and left to the air.
