Torsion Spring Replacement
One 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.
Torsion Spring Replacement
In plain words
Think of the opener as a helper, not a lifter. It is built to push and pull a door that already weighs almost nothing thanks to the springs; asking it to hoist a full-weight door strains the trolley, bends the top section and wears the gear drive. Spring replacement puts the load back where it belongs. After fitting and winding the new spring, the technician balances the door, then reconnects the opener and resets its force and travel settings so it runs within its design limits. Owners usually notice the opener sounds calmer and the door moves more evenly afterwards.

How the visit goes
Confirming the system layout
Doors are set up in several ways, and the replacement has to match. The technician notes whether there is one spring or two, whether the shaft is a single piece or two halves joined by a coupler, and what the shaft diameter is. Drum type is read from the drums themselves: standard-lift drums for a normal ceiling, high-lift or vertical-lift drums where the door rises well above the opening, or a rear-mounted assembly in a low-headroom garage. Track radius and headroom are measured because they change how many turns the spring needs and which drums it must work with.
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.
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
Same fees day, night or weekend
1Age 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.
2Oversize or non-standard doors
Very wide doors, tall doors, carriage-house doors with heavy overlays and light-commercial doors may need duplex springs, multiple springs or larger drums, which changes both the hardware and the method.
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
Are springs different for a heavy wooden or insulated door?
Yes, and this is exactly why the door is weighed. A solid wood door or a thick insulated steel door can weigh far more than a single-skin steel door of the same size, so it needs heavier wire, a larger coil or a second spring to balance. The technician measures the actual weight and selects accordingly, so the finished door lifts as easily by hand as a lighter one.
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.
What 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.
