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
The heart of this service is matching, not just swapping. Two springs can look identical and behave very differently, because the force a torsion spring produces depends on its wire thickness, inside diameter, length and wind direction, and the right combination depends on the door's weight, height, drum type and track lift. The technician measures all of those before choosing a spring, then confirms the choice the only way that counts: lifting the finished door by hand and feeling it stay put at waist height. A properly matched spring lasts longer and keeps the opener working easily.
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
Checking what the spring anchors to
A torsion spring pushes against a centre bracket bolted to the header above the door, and that anchor takes the full reaction force every cycle. The technician checks that the bracket is fastened into solid framing with proper lag bolts, that the header wood has not split or softened with moisture, and that the end bearing plates on each side are square and tight to the jamb. Loose or corroded fasteners are noted for replacement. A sound anchor keeps the shaft level and the spring pulling straight, which protects both the new spring and the bearings that carry it.
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
1Converting 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.
2Opener 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.
3One spring or two
A single-spring door needs one spring; a paired system is usually replaced as a matched set of left- and right-wound springs. The number of springs and whether both are replaced is the largest single influence on the scope.
Torsion Spring Replacement: questions
Why is my door sitting crooked since the spring broke?
On a two-spring door, one intact spring keeps pulling on its side while the broken side goes slack, so the door lifts unevenly and a cable can jump its drum. The technician levels the door, reseats the cables in their drum grooves and evens the tension after the new spring is fitted. Rollers and track are checked for damage from the crooked travel so the door runs square again.
If only one spring broke, should both be replaced?
On a two-spring door both springs have completed the same number of cycles, so the intact one is usually close to the end of its life as well. Replacing the pair gives the door two matched springs sharing the load evenly and a fresh cycle count on both sides. The technician looks at the remaining spring's condition and the door's configuration, then explains the reasoning so you can choose the scope with a clear picture.
What other parts are often replaced with the spring?
The shaft is free during a spring change, which makes it the natural time to renew the centre bearing and end bearings if they grind or wobble. Lift cables that show fraying or rust at the bottom brackets are replaced so the new spring pulls on sound steel, and cracked or worn drums are swapped. On older doors, a corroded centre bracket or loose lag bolts may also be addressed. Each item is shown and explained before it is added.
