Torsion Spring Replacement
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
Torsion spring replacement is really a service on the whole balance system. The spring sits on a shaft that turns in a centre bearing and two end bearings, drives a pair of cable drums, and lifts the door through two steel cables. With the shaft out for the new spring, the technician inspects each of these parts, replaces bearings that grind or wobble, checks cables for fraying at the bottom brackets and confirms the drums are seated. Refreshing worn pieces at the same time means the new spring works on smooth hardware and the door runs true.
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
Making the door safe to work on
Before anything is measured or removed, the door and the opener are put into a controlled state. The opener is unplugged and the trolley released so the motor cannot move the door partway through the job. The door is brought fully closed, and locking pliers or clamps are set on the track just above a roller so the door stays down while spring tension changes. The technician clears the space beneath the shaft, checks that people and pets are out of the garage, and looks at where a vehicle sits so the ladder and winding position are safe.
Reconnecting and testing the opener
With the door balanced, the opener comes back into service. The trolley is re-engaged, power is restored and the door is run open and closed under motor. Travel limits are adjusted so the door seals at the floor and stops at the right height, and force settings are set to the light load a balanced door presents. The technician then places an object flat on the floor in the door's path and confirms the door reverses on contact, and passes a hand through the photo-eye beam to confirm the door reverses again. These checks close the visit on a working, safe system.
Keeping the spring in good shape
A little care keeps the new spring running smoothly for its full life. Once or twice a year, spray the coils with a garage-door lubricant so the steel moves without rubbing, and do the same for the hinges, roller bearings and the end bearings at each side of the shaft. Autumn is a good time, since cold thickens grease and stiffens hardware. Leave the track dry, because lubricant there collects grit. Over the years, glance at the spring for gaps or rust streaks, and if the door starts to feel heavier by hand, book a balance check before a spring reaches its limit.

What affects the quote
Age of the door and matching hardware
Older doors sometimes carry shaft diameters, bearing plates or drum patterns that are no longer common. Sourcing compatible hardware or adapting the mounting adds to the scope for these doors.
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.
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.
What to have ready
- Do you know the door's age or when the springs were last replaced?
- Did you hear a loud bang before the door stopped working?
- How many springs are mounted above the door, one or two?
Torsion Spring Replacement: questions
QuestionsCan I keep using the opener until the technician arrives?
The kindest thing for the door is to leave it where it is and use another entrance. An opener is designed to move a door the springs have already made light; asking it to lift a full-weight door strains the trolley and gear drive and can crease the top section. Keeping the door still and clear of people until the spring is replaced protects the rest of the system from extra repairs.
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 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.
