When a torsion spring fails it does so with one flat, loud report from inside the garage, and most people assume a shelf has collapsed or something large has toppled over. From that moment the door is either completely stuck or alarmingly heavy to shift, and the opener will strain at it and quit, because its job was only ever to guide a door that something else was holding up.
There is a specific reason Lynwood springs fail earlier than their rated cycle count suggests they should, and it is worth understanding before you book anybody. It is not usually the wrong spring, and it is not usually an old spring. It is a correctly specified spring that has been working in an abrasive environment on a shaft whose fixings have been vibrating loose underneath it.
Why springs on this corridor fail short of their cycle rating
A torsion spring is rated in cycles, one open plus one close, and that rating assumes a set of clean operating conditions. Among them is that the coils, which close on each other as the spring winds and open as it unwinds, are moving against air and a thin protective coating rather than against anything solid. On a door near a heavily trafficked corridor that assumption quietly stops being true. Fine abrasive material — road grit, tyre wear, brake friction dust — settles on the spring and works into the gaps between the coils, where it has nowhere to go and nothing to flush it out.
What happens next is straightforward mechanics. Every cycle, the coils close on that trapped material and grind against it. The protective coating on the wire is cut through first, usually in a distinctive banded pattern on the inner faces where the coils meet. Once bare steel is exposed, ordinary humidity does the rest and a corrosion pit forms. A pit in a spring is not a cosmetic mark: it is a stress riser, a point where the load concentrates instead of distributing evenly around the wire, and it is where the fracture starts. That is why a spring here can break at a fraction of its rated cycles while looking, from three feet away, entirely healthy.
The vibration side compounds it. The winding cones at the ends of a torsion spring are held on the shaft by set screws, and the bearing plates carrying the shaft are held to the header by lag fixings. Under sustained low-frequency vibration those threaded fittings creep. A cone set screw that has backed off allows the cone to shift slightly on the shaft under load, which loses a little tension and puts a shock into the spring at each start; a bearing plate that has loosened lets the shaft find a fractionally different centre, so the two drums stop working at the same effective radius and the two sides of the door stop sharing the load evenly. A spring carrying more than its half of an unbalanced door burns through its life faster, and nobody has touched a thing.
How we specify, fit and then protect the replacement
We work from the door's weight, not from the broken spring. A spring that has failed has already changed shape — its coils have shifted and its length is no longer what it left the factory with — so what you measure is its end state rather than its specification. Ordering a match for it just repeats whatever judgement the previous fitter made, mistakes included. Instead the counterbalance comes off, the door goes on a scale, and wire diameter, inside diameter and wound length are derived from that figure together with the travel height and the drum size. Across a wide opening we fit a pair, so the load is divided and a future failure leaves the door partly held rather than entirely unheld.
Then we deal with the things that shortened the last spring's life, because fitting a new spring into an unchanged situation buys you a repeat of the same repair. The shaft, both bearing plates and both winding cones are checked and their fixings set correctly, with thread-locking compound where the assembly allows it, so that the cone cannot creep on the shaft under vibration. Both drums are checked for seating and matched radius. The cables come with the springs unless they are genuinely recent, because a cable that has spent years being loaded by an unbalanced door is not a component to leave behind a new spring.
The last part is protection, and it is specific to this location. We clean the shaft assembly down properly rather than lubricating over the top of existing contamination, because heavy grease applied to a dirty spring simply glues the abrasive in place. What goes on afterwards is a light penetrating lubricant applied sparingly along the coils — enough to leave a protective film on the wire, not enough to build a sticky surface that collects the next season's dust. We will show you how to do that yourself and roughly how often, and near a corridor that interval is genuinely shorter than the generic advice in a manufacturer's booklet.
Please leave this particular job to somebody with winding bars
There are very few jobs we would discourage a capable homeowner from attempting, and this is one of them. A wound torsion spring has a great deal of energy locked into it, and getting that energy out safely takes bars of the correct diameter and length used in a particular order. Improvising with a screwdriver, a length of reinforcing bar or an adjustable spanner produces injuries that are severe and permanent, and everybody who has spent time in this trade knows somebody it happened to. There is a local wrinkle as well: a spring that has been quietly corroding in a pit nobody can see behaves less predictably than a clean one. That is not a reason to be nervous of your own garage, but it is a good reason not to experiment on it.
If your door is stuck shut on a broken spring, leave it shut. Do not heave at it, and above all stop pressing the button. An opener is built to move a door the springs are already holding up; it is not a hoist. Asking it to take the full dead weight shears the nylon drive gear and can take the control board with it, so you finish up paying for an opener as well as a spring to no purpose whatsoever. Park on the street or out on the apron rather than nose-in against a door nothing trustworthy is supporting.
If the spring failed with the door open, the correct instruction runs against instinct: keep away from the red release cord and make no attempt to bring the door down. With no counterbalance the door holds its whole weight unaided, and freeing it from the carriage drops it. Leave it where it stands, get vehicles, children and animals out of the garage and away from the opening, and ring us. Somebody answers at any hour, and whoever is nearest to you comes out, whatever the time.
Spring Repair in Lynwood — FAQs
- On a two-spring door, yes, and we recommend it every time here for a reason beyond the usual one. Both springs have carried the same door through identical operations, so the survivor is not healthy, it is simply the one that has not gone yet. Near a corridor there is a second argument: both springs have been sitting in the same abrasive environment, so the coating damage and pitting that finished the first one is almost certainly present on the second. Replacing one gives you an unbalanced door now and a second call-out with a second labour charge shortly afterwards.
- That is the most common question we get in this city and it usually has the same answer. A cycle rating assumes clean operating conditions, and a spring on a door near a busy corridor is working with abrasive material trapped between its coils. The coils grind on that material, cut through the protective coating, and a corrosion pit forms and becomes the point where the wire eventually fractures. So the spring has not necessarily done anything like its rated number of cycles — it has simply been worn through from the outside rather than fatigued from within. Correct specification plus proper cleaning and light lubrication is what changes the outcome next time.
- Yes, and it is worth asking while the door is already being worked on. A high-cycle spring achieves the same lift using a larger wire on a longer body, so each operation stresses it less and there is more material for a surface defect to work through before it matters. Since we are fitting springs anyway it adds no labour. The other half of the answer costs nothing at all: keeping the coils clean of settled grit and giving them a light film of the right lubricant a couple of times a year addresses the actual mechanism that has been shortening your springs' lives.
