Torsion Spring Replacement in Wyebridge
You heard a sharp bang from the garage, and now the opener hums for a second and gives up.
In plain words
Think of the opener as a helper, not a lifter. It is built to push and pull a door that already weighs almost nothing thanks to the springs; asking it to hoist a full-weight door strains the trolley, bends the top section and wears the gear drive. Spring replacement puts the load back where it belongs. After fitting and winding the new spring, the technician balances the door, then reconnects the opener and resets its force and travel settings so it runs within its design limits. Owners usually notice the opener sounds calmer and the door moves more evenly afterwards.
How the visit goesOne side of the door sits higher than the other in the tracks, and a lift cable is hanging slack or has jumped off its drum. On a two-spring door this often follows one spring letting go while the other keeps pulling.

How the visit goes


Reading the spring itself
The first measurements come from the spring that is already on the shaft. The technician measures wire thickness across a run of ten or twenty coils, the inside diameter of the coil, the overall length of the spring when relaxed, and the wind direction, which is read from how the coils lean. On a two-spring door each spring is checked separately, because a left-wound and a right-wound spring sit on either side of the centre bracket. Any tag or colour marking is noted too. These numbers narrow down what the door was built with, and together with the door's weight they point to the correct replacement.
Setting the cables and drums
A balanced door depends on both cables pulling equally, so drum work gets careful attention. Each lift cable is wound into the grooves of its drum with the loop secured on the drum pin, and the drums are slid firmly against the end bearing plates. The technician rotates the shaft to take up slack, then sets tension so both cables are equally taut with the door fully closed; a level across the shaft confirms it is sitting true. Drum set screws are tightened to the shaft in this position. Even cable tension keeps the door square in its tracks through every part of its travel.
Using the manual release with confidence
A balanced door is also a door you can operate safely by hand when the power is out. Pull the red release cord with the door closed to free the trolley, then lift the door with both hands on the handle or the bottom section; it should rise smoothly and stay open at full height. To re-engage, pull the cord toward the door until the trolley clicks back onto the carriage, or simply run the opener, which reconnects on most models. Because the spring now carries the weight, this is light work, and it is the recommended way to get a vehicle out during an outage.

What affects the quote
Door size and weight
A double-width door, a solid wood door or a thick insulated door weighs far more than a single-width steel panel, calling for heavier wire, longer coils or more springs to balance it.
Condition of the lift cables
Cables that show fraying, rust or a kink at the bottom brackets are replaced so the new spring pulls on sound steel. Two good cables mean this item stays off the list.
Damage from the break
If the opener was run against a broken spring, the top section may be bowed, the trolley bent or a hinge strained. Correcting these so the balanced door runs on straight hardware adds to the scope.
What to have ready
- How many springs are mounted above the door, one or two?
- Is the door currently closed, open, or stuck partway?
- Can you see a gap in the spring above the door?
Torsion Spring Replacement: questions
QuestionsAre springs different for a heavy wooden or insulated door?
Yes, and this is exactly why the door is weighed. A solid wood door or a thick insulated steel door can weigh far more than a single-skin steel door of the same size, so it needs heavier wire, a larger coil or a second spring to balance. The technician measures the actual weight and selects accordingly, so the finished door lifts as easily by hand as a lighter one.
Will the new spring look the same as the old one?
Not necessarily, and that is fine. The paint colour on the winding cone or coil is a code that identifies wire size and wind direction, and different suppliers use their own schemes, so a matched replacement can carry a different colour than the spring it replaces. What matters is that the wire size, diameter, length and wind direction suit the door's weight and height, which is confirmed by the balance test.
What photos help when I call?
A picture of the full spring assembly above the door, showing the centre bracket, both drums and how many springs there are, tells the technician a great deal. Add a close shot of the broken spring gap and any tag or colour marking on the cones, a photo of the cables at the bottom brackets, and one of the opener. These help confirm the door's configuration so the right springs and hardware are on the truck.
