A torsion spring letting go announces itself as one flat crack from inside the garage, loud enough that neighbours come out to check whether something has hit a car. What is left is a door that either will not shift at all or is frighteningly heavy to lift, and an opener that strains, slows and gives up, because it was built to guide a counterbalanced door rather than hoist a dead one.
There is a second half to a spring job in this city that most people never hear about, and it is the part we would most like you to know before you book anyone. Correcting the springs changes how the door behaves. The opener has been quietly compensating for the old behaviour, sometimes for years, and unless it is reset to the corrected balance the job is not actually finished.
The spring that was fine, and the opener that hid its drift
The interesting Paramount spring call is not the one where somebody fitted the wrong spring. It is the one where the spring was correctly specified, correctly wound, and simply drifted — as every torsion spring does. A spring does not hold its rated lift in a straight line to the end and then stop. It loses a little tension gradually across its service life, so the balance point moves by degrees, and on a well-behaved door nobody notices because the difference between one month and the next is imperceptible.
What normally happens next is that the door gets heavier to lift by hand and the household stops lifting it by hand, so nobody has a reference point. The opener absorbs the shortfall. If that opener is already running at the top of its rating because a heavier door was hung under it years ago, it has no reserve to absorb anything, so it starts stalling or reversing partway — and the standard fix is to wind up the force setting. That masks the drift again. Each increment buys another year or two of apparently normal operation while the underlying balance gets steadily worse and no one has any way of seeing it.
By the time the spring actually fails, or the door becomes obviously heavy, the opener has been compensating for a long time and its settings reflect a door that no longer exists. This is why we ask, on a spring call, when the door was last operated by hand and whether the force adjustment has ever been touched. Owners rarely know the answer, and that is fine. The settings themselves tell us, and they tell us how much masking has been going on and for how long.
How we specify the replacement, and why we weigh rather than copy
We do not read the wire size and length off the broken spring and order the same again. It is how a good deal of this work gets done and it is not defensible, because a failed spring has stretched — its coils have shifted and its overall length is no longer the length it left the factory at, so the figure taken off the wreckage was never the right figure to begin with. We gauge the wire across a counted run of coils on the undamaged portion, establish inside diameter and wound length from there, and then check the whole specification back against the door's weighed mass, the height it travels through and the diameter of the drums fitted to the shaft.
The weighing is not a formality in this city. Because doors here have been replaced independently of everything around them, the door currently hanging is very often not the door the system was originally designed around. We put a scale under the bottom section with the tension off and read the actual figure, then specify from that. It is the same measurement that tells us whether the opener above is inside its rating, so it earns its keep twice on a single visit.
Where a door carries two springs and one has gone, we recommend replacing the pair every time. They went on together, they have run precisely the same number of cycles, and the one still intact is not in good condition — it is just the one whose turn has not arrived. We renew the lift cables alongside the springs unless they are genuinely recent, and we inspect the drums, end bearings and centre bearing plate at the same time, because those parts have aged on exactly the same cycle count. Winding a fresh spring onto a fatigued cable is a repair that comes back.
Re-commissioning the opener to the corrected balance
This is the step that gets skipped, and skipping it is genuinely dangerous rather than merely untidy. Once the springs are correct, the door is lighter and moves more freely than it has in years. The opener is still set for the old door — wound-up force, travel limits set to where the heavy door used to stop, a close force that was calibrated against resistance that no longer exists. An opener carrying an inflated force setting on a now-correctly-balanced door will push through an obstruction with a great deal more authority than it did the day before, and the contact reversal that should stop it is exactly the thing that has been turned down.
So the spring job includes the opener. We reset the force adjustments down to the door as it now behaves, reset the travel limits to the new stopping points, and then test the reversal with a solid object laid flat on the floor in the door's path near the middle of the opening — a short length of timber on its side, about an inch and a half thick. The door has to meet it, stop, and return promptly. We adjust and retest until it does that cleanly, and we run the photo-eyes separately, because they are a different system and passing one test says nothing about the other.
We also check the opener's rating plate against the weight we have just measured, since we have both numbers in front of us at that point. If the opener is comfortably rated for the door, it goes back into service properly set and you will get years out of it. If it turns out to have been running over its rating all along, you will hear that with the figures attached, along with what it means for how long the drive train is likely to last. That is information, not a sales step — plenty of owners choose to run it and keep an eye on it, and knowing is still better than not knowing.
Spring Repair in Paramount — FAQs
- Because the opener has been set to the door as it was, and the door has just changed. The force adjustment it has been carrying was calibrated against a heavy, badly balanced door, and on the corrected door that same setting means it will shove through something it should stop for. Resetting the force and travel limits and confirming the door reverses on contact takes a few minutes at the end of a spring job. Leaving it as it was hands you back a door that works beautifully and has its safety margin turned down.
- No, and this is the single instruction that saves people the most money. A motor exists to guide a door that its springs are already carrying. Working it against a door whose spring has gone will chew through the nylon drive gear, can take the logic board with it, and adds an opener to a bill that was only ever going to be a spring. If the door is already closed, leave it closed and park on the drive. If it has stopped part way up, keep people and vehicles out from underneath it altogether — whatever is still supporting it is doing so unevenly.
- We discourage very few jobs, and this is one of them. A torsion spring under tension holds a substantial quantity of stored energy, and getting that energy out safely depends on correctly sized winding bars used in a set order. The injuries come almost entirely from the substitute tool in the winding cone — a screwdriver shank, a length of rebar, whatever happened to fit — and the damage they do to hands and faces does not heal back. Being careful and being handy are not the variables; having the right bars and following the right sequence are. Extension springs along the horizontal tracks are no more forgiving.
