A torsion spring letting go is a single flat report from inside the garage, loud enough that people come out of neighbouring buildings to find out what happened. What is left afterwards is a door that either will not move at all or is frighteningly heavy, and an opener that pulls, strains and gives up, because it was built to guide a counterbalanced door rather than to hoist a dead weight.
There is a second thing about springs that this city's calls bring out and that almost nobody connects, so it is worth saying at the front. The balance of a door is not only a mechanical property and a safety property. It is a security property as well, and it is directly tied to the release cord hanging from the trolley above your head.
A balanced door is a door one person can lift, and that is deliberate
Here is what correct balance means in practice. Uncouple the door from the opener with the manual release, take hold of the bottom section, and lift. A properly counterbalanced door — of any size, including a wide double — moves under moderate hand pressure from one person and holds position wherever you stop it, at the floor, at waist height, halfway, near the ceiling. It does not run away downward and it does not float up. That is not a happy accident. It is the entire design intent of a counterbalance system: the springs hold very nearly the whole mass of the door, and everything else, including the motor, only has to guide a load that is already supported.
The consequence people do not draw is that a well-maintained garage door is, by design, an object that one adult can move by hand in a few seconds. The emergency release exists precisely because that is true. It is a legal and practical necessity — a power cut, a failed board, a stripped gear or a person shut inside all require a way to disconnect the motor and move the door manually — and it works because the door was engineered to be movable by hand. So the release is not a weakness bolted onto an otherwise secure system. It is the visible end of the same property that makes the door safe to own.
Which is why, on this city's older garages, we treat balance and access as one conversation rather than two. Once you accept that the door is meant to be liftable by hand, the security question stops being can this door be moved and becomes who can reach the thing that disconnects it. That is a much more tractable question, and it has cheap answers: a release cord kept to the minimum usable length and clear of the top section, a release handle designed to resist being pulled from outside the opening, an external release keyhole either upgraded to a decent cylinder or blanked off where the garage has another entrance, and a manual track lock or a clamp fitted above a roller when the property is going to stand empty for a stretch. None of those interfere with the emergency function. They just stop it being available to the wrong side of the door.
A door too heavy to lift is not secure — it is under-sprung
The opposite failure is the one we see more often, and it gets misread as security surprisingly regularly. A door with a failed spring, a badly under-specified spring, or a spring that has drifted a long way down from its rated lift becomes very heavy indeed. Nobody can raise it by hand, and an owner will sometimes take a quiet comfort in that. It is a false comfort and an expensive one. That door is not being secured by anything. Its weight is simply no longer supported by the system that is supposed to support it, and the load has gone somewhere else.
Where it has gone is the problem. With the counterbalance gone or reduced, the cables, the drums, the bottom fixtures and the top brackets are carrying loads none of them were specified for, and the opener is being asked to lift rather than guide. On the way down, the same imbalance means the door has more effective weight behind it than the safety systems were commissioned against. The trolley and the carriage arm end up as the only thing holding the door in the closed position, and a plastic carriage on a rail is not a lock, was never designed as one, and fails in a way that leaves the opening standing wide rather than shut. If a heavy door is what is keeping the building closed, the building's security depends on a drive train that is actively being destroyed.
There is a practical consequence too, and it is the one that catches people out. A door that cannot be lifted by hand cannot be opened in a power cut, and it cannot be opened by somebody who needs to get out of the garage in a hurry. That is precisely the situation California's battery backup requirement addresses for anything installed since 2019: a compliant modern opener keeps operating when the supply is down, which turns a genuine stranding into a non-event. It is one of the few regulatory requirements in this trade that delivers an obvious everyday benefit rather than an abstract one, and it is worth having for its own sake. What it is not is a substitute for correct balance. A door that is properly counterbalanced can be moved by hand whether the power is on or off, and the backup simply means you rarely have to.
How we specify a replacement, and what gets set afterwards
We do not read the wire size and length off the broken spring and order the same again. 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 figures taken off the wreckage were never the right figures. We gauge the wire across a counted run of coils on an undamaged portion, establish inside diameter and wound length from there, and check the whole specification back against the door's weighed mass, the height it travels through and the diameter of the drums on the shaft. The weighing is done with a scale under the bottom section with the tension off, not estimated from the door's width, because two doors of the same width can differ enormously in mass depending on construction.
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 survivor is not in good condition — it is simply 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, the end bearings and the centre bearing plate at the same time, since all of them have aged on the same cycle count. Winding a fresh spring onto a fatigued cable is a repair that comes back. And please do not attempt this replacement yourself: a wound torsion spring holds a serious amount of stored energy that has to be released through correctly sized winding bars in a set sequence, and the injuries in this trade come almost entirely from an improvised tool in the winding cone.
Then the part that gets skipped elsewhere. Once the springs are right the door is lighter and moves more freely than it has in years, and the opener is still set for the door as it used to be — force wound up, travel limits set to where a heavy door used to stop. An inflated force setting on a now correctly balanced door will push through an obstruction with considerably more authority than it did the day before. So we reset the force to the door as it now behaves, reset the travel limits, and test the contact reversal with a solid object laid flat in the door's path near the middle of the opening, adjusting and retesting until the door meets it, stops and returns promptly. We check the photo-eyes separately, because they are a different system. And we go through the release arrangement with you before we leave, because you now have a door that one person can lift, which is exactly how it should be.
Spring Repair in Baldwin Park — FAQs
- With the door fully closed, pull the manual release cord to uncouple it from the opener. Lift the door by hand to about waist height and let go. It should stay put, or drift very slowly. If it drops, the springs are no longer holding the weight; if it rises on its own, they are wound past the door. Either way it is worth a call before something else takes the strain. Do it twice a year, keep your hands flat on the door face and away from the joints between sections, and get a second pair of hands on a wide door. Re-engage the trolley afterwards by running the opener until the carriage picks it up. If the door already feels immovably heavy before you start, stop there and leave it — that is the condition where a spring has failed and the release should not be pulled at all.
- No, and it is worth being direct about that because the intuition is understandable. A stiff or heavy door is not resisting anybody; it is a door whose springs have stopped carrying their share, which means the cables, drums, fixtures and the opener are all taking loads they were not specified for. It will fail, and when it fails it commonly fails with the door part way or stuck open, which is the opposite of secure. It also cannot be opened by hand in a power cut. If you want the door to be harder to open from outside, the answer is the access side — the release arrangement, the code the opener answers, what is paired to it, and a manual track lock for extended absences — never a deliberately unbalanced mechanism.
- No, and this is the single instruction that saves people the most money. The motor exists to guide a door its springs are already holding. Driving it against a door with a failed spring strips the nylon drive gear, can take the logic board with it, and turns a spring job into a spring-and-opener job for no benefit at all. If the door is already down, leave it down and park outside. If it has stopped part way, keep people and vehicles out from underneath it entirely, because whatever is still supporting it is doing so unevenly. If it is stuck open and the building is standing exposed, tell us that when you ring — it moves the job up the list.
