Torsion Spring Replacement in Toronto
You heard a sharp bang from the garage, and now the opener hums for a second and gives up.
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 goesLooking up at the coil above the door, you can see a clean split with a gap of several centimetres between the two halves. The rest of the spring looks fine, but the door has become almost impossible to move by hand.

How the visit goes
Understanding how the door is used
How the household uses the door shapes the spring that suits it. The technician asks how many times a day it typically opens, whether it is the main entrance to the home, and when springs were last replaced, if ever. A door cycled eight times a day accumulates use far sooner than a weekend garage. Age of the door and any previous partial repairs are also relevant, especially a single spring changed on a paired system. This conversation lets the customer choose between a standard-cycle spring and a higher-cycle option with a clear picture of what each means for them.
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.
Relief for the opener
Your opener benefits as much as the door. With the spring carrying the weight again, the motor, gear drive, trolley and rail return to the light duty they were designed for, which tends to mean a longer working life and less noise. Force settings have been reset to suit a balanced door, so the safety reversal reacts to a genuine obstruction rather than to a heavy door. Once a year, repeat the simple reversal test by placing a length of wood flat on the floor in the door's path and confirming the door reverses on contact. The opener's photo-eye sensors deserve a wipe at the same time.

What affects the quote
Spring specification
The wire size, inside diameter and length that the door's weight and height demand determine which spring is fitted. Larger doors take larger springs, and unusual combinations may need specially wound coils.
Opener reconnection and testing
Resetting force and travel limits and running the reversal and photo-eye tests are part of the visit. An opener with worn gears or a slipping trolley uncovered during testing becomes a separate item.
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
- Can you send a photo of the spring area and the opener?
- Is a vehicle parked inside the garage right now?
- Is there a working power outlet near the opener and clear space under the shaft?
Torsion Spring Replacement: questions
QuestionsWhat is the difference between torsion and extension springs?
Torsion springs mount on a shaft above the door and twist to store energy, lifting the door through cables and drums. Extension springs run alongside the horizontal tracks and stretch as the door closes, pulling it up through pulleys. Torsion systems tend to lift more evenly, take up less space beside the tracks and are the standard on most modern doors. Both are professional service items because of the energy they hold.
What about a garage with very little space above the door?
Low-headroom garages use a different arrangement: the spring assembly may be mounted at the rear of the horizontal tracks, or special low-headroom drums and track bring the door up with less clearance. Replacement follows the same principles, but the drums, cable routing and turn count differ. The technician identifies the system on arrival and brings hardware that suits it, so the door balances correctly in the space available.
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.
