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
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 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.
Renewing the bearings while the shaft is out
Removing a spring frees the shaft, which is the moment to deal with bearings. The centre bearing, which sits in the bracket between the springs and carries the shaft under constant load, is pressed out and replaced if it grinds or has play. End bearings in the plates at each side are checked the same way. New bearings are seated square, and the shaft is slid back through them and turned by hand to confirm smooth rotation before any spring is wound. Smooth bearings reduce the effort the spring and opener have to overcome, which extends the life of both.
Signs worth noticing going forward
A healthy spring system is quiet and even, so changes stand out. Listen for a new grinding or popping sound as the door moves, watch that both sides of the door rise together, and look at the cables for fraying or a loop that has left the drum groove. Rust streaks below the shaft, a door that takes noticeably more effort by hand, or an opener that starts to strain are all early indicators that something in the balance system wants attention. Catching these early keeps repairs small and lets the household plan a visit rather than face a stuck door.

What affects the quote
Same fees day, night or weekend
1Cycle 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.
2Shaft 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.
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
Does the opener need adjusting after the spring is replaced?
Usually a little. A balanced door presents a much lighter load than a door with a broken spring, so the opener's force settings are reset to suit it, and the travel limits are checked so the door seals at the floor and stops cleanly at the top. The technician then runs the reversal test and the photo-eye check to confirm the safety system responds correctly with the new balance.
How do you know which spring my door needs?
The spring is chosen from measurements rather than appearance. The technician records the door's width, height and weight, the drum type and track lift, and reads the old spring's wire size, inside diameter, length and wind direction. Those inputs together determine the spring that will balance the door. The choice is confirmed on the spot by lifting the finished door by hand and feeling it hold at mid-height.
What is the difference between galvanized and oil-tempered springs?
Oil-tempered springs are the traditional dark grey or black coil; they hold their tension well over time and are widely used. Galvanized springs have a zinc coating that resists rust, which is useful in damp garages, though they tend to relax slightly and may need a small adjustment after settling in. Both are available in standard and high-cycle ratings, and the technician can explain which suits your garage.
