Torsion Spring Replacement in Bramalea Woods
Looking up at the coil above the door, you can see a clean split with a gap of several centimetres between the two halves.
In plain words
The finished result is a door that behaves the way a good garage door should: it lifts by hand with light effort, stays where you leave it at mid-height, closes softly and lets the opener run with little strain. Reaching that point involves measuring the door, choosing a matched spring, winding it to the correct turns and testing the balance through the full travel. The technician then runs the opener's reversal test and lubricates the moving parts. You are left with a record of the spring installed, so future service starts from known specifications.
How the visit goesAfter 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.

How the visit goes
Weighing the door honestly
A spring is chosen for a specific load, so the technician establishes what the door actually weighs rather than guessing from its appearance. With the opener released and any remaining tension safely removed, a scale under the bottom section gives a real figure. Construction is recorded alongside it: single-skin steel, insulated steel sandwich, solid wood, glass panels or an aluminum frame all sit at very different weights for the same size. Extras count as well, including added windows, a heavy bottom seal or panels replaced over the years. That weight, with the door's height, is the basis for the spring specification.
Balancing the door by hand
Once the clamps are off, the technician lifts the door by hand to about waist height and lets go. A balanced door stays where it is, or drifts only slightly. If it rises on its own, the spring has a little too much tension and is eased a quarter turn; if it drops, a quarter turn is added. The door is then run through its full travel, watching that both sides move together and the sections stay flat in the tracks. This is repeated until the door feels light and stops cleanly at several heights, which is the standard the whole job is measured against.
Your spring on record
The technician leaves you with the specification of what was installed: wire size, inside diameter, length, wind direction and the cycle rating chosen, along with notes on any bearings or cables replaced. Keep that record with the door's paperwork or photograph it. It means future service starts from known numbers rather than fresh measurement, and if a door section or opener is ever changed, the installer can confirm the springs still suit the door's weight. Many technicians also mark the installation date on the spring or centre bracket so the age of the system is easy to read later.

What affects the quote
Spring finish
Oil-tempered and galvanized springs suit different garages. A coated or galvanized spring for a damp or salt-exposed space is a choice the customer can make when the specification is discussed.
Cycle rating chosen
A standard-cycle spring and a high-cycle spring balance the door the same way but differ in wire and length. Choosing a longer-life spring is an option the household can weigh against how often the door is used.
Shaft condition
A bent, badly rusted or worn shaft is replaced so the drums and bearings turn true. Coupled two-piece shafts and their coupler are checked at the same time.
What to have ready
- How many springs are mounted above the door, one or two?
- Is there a working power outlet near the opener and clear space under the shaft?
- Can you see a gap in the spring above the door?
Torsion Spring Replacement: questions
QuestionsWhat should I do before the technician arrives?
Keep the door closed and leave it alone, move any vehicle you can reach out of the way or at least clear the space in front of the door inside the garage, and make sure there is room for a ladder beneath the shaft. Note whether there is one spring or two and whether a cable is loose. A photo of the spring area, the drums and the opener helps the technician bring the right parts.
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.
Can extension springs be converted to a torsion system?
In many garages, yes. A conversion adds a shaft, centre and end bearings, drums and torsion springs above the opening and removes the extension springs and pulleys from beside the tracks. It needs enough headroom above the door for the shaft and solid framing for the centre bracket. The technician measures the space and the door before recommending it, and the result is smoother, more even lifting with hardware kept clear of the sides.
