Torsion Spring Replacement
After pulling the red release cord, you tried lifting the door yourself and it would barely leave the floor. A door that used to glide up with one hand now takes real effort, which points to the counterbalance rather than the opener.
Torsion Spring Replacement
In plain words
Torsion spring replacement restores the counterweight that makes a garage door light enough to lift. A sectional door often weighs more than a fridge, and the spring above the opening carries nearly all of that load, storing energy as the door closes and releasing it as it opens. When a spring breaks or wears out, the technician removes it, fits a spring matched to the door's weight and height, winds it to the correct number of turns and checks that the door balances at every point of travel. The opener returns to doing its light share of the work, and the door moves smoothly and evenly again.
How the visit goesYou heard a sharp bang from the garage, and now the opener hums for a second and gives up. The door lifts a few centimetres at most, then settles back down as if something very heavy is holding it in place.

How the visit goes
Looking for damage the break left behind
When a spring snaps, the door's full weight suddenly lands on parts that were never meant to carry it. The technician checks the top section for a bow or crease where the opener trolley pulled, looks at the trolley and rail for bending, and inspects hinges and roller stems along the top panel. If the door came down crooked, the rollers and track are examined for a jump or a dent. Catching these effects before the new spring goes in means the balanced door runs on straight hardware rather than dragging a distorted section through the tracks.
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.
Through the seasons
The new spring has been set for the door as it is today, and the seasons are part of its life. Cold mornings make steel and grease a little stiffer, so the door may feel marginally slower in deep winter while still balanced; lubrication in autumn helps. Slush and road salt carried in on tires settle on the bottom brackets and cable ends, so a rinse and a light spray in spring slow corrosion where the cables anchor. Summer humidity is easier on hardware but rewards a dry, clean track. Small seasonal habits like these let the spring reach its full rated cycle count.

What affects the quote
Same fees day, night or weekend
1Condition 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.
2Centre and end bearings
With the shaft out, bearings that grind, wobble or have seized are renewed. Smooth bearings reduce the load on the spring and opener, and their condition is confirmed by hand during the check.
3Converting from extension springs
Moving a door from extension springs to a torsion system adds a shaft, bearings, drums and brackets, and removes the old pulleys, which is a broader job than replacing an existing torsion spring.
Torsion Spring Replacement: questions
Can a spring be adjusted rather than replaced?
A spring that is intact but has relaxed slightly can be given a little more tension, within limits, to restore balance; this is a normal adjustment on a door that has settled. A spring with a broken coil is replaced as a unit, since the wire has reached the end of its life. The technician checks the condition of the steel and recommends whichever restores a balanced, safe door.
What happens if the header wood or centre bracket is damaged?
The centre bracket anchors the spring's reaction force to the framing above the door, so it has to be solid. If the header has split or softened, or the lag bolts have pulled, the technician can refasten into sound wood, add a reinforcing plate or replace the bracket before the new spring is wound. Dealing with this first keeps the shaft level and the spring pulling straight, which protects the bearings and the door.
My car is inside the garage; how do you get the door open?
Once the technician is on site, the door is secured and the spring replaced with the door in its closed position, which is how spring work is always done. When the new spring is wound and the door balances, it lifts normally and the vehicle drives out. There is no need to force the door open beforehand; leaving it closed keeps the door square and the job straightforward.
