- The call
- Open the door by hand and it drifts back down on its own, a little at first and then all at once. Nothing is broken that you can see, but the springs along the tracks look tired, rusty and slightly sagging.

It is the first hard frost of the year and the door on the old detached garage has stopped halfway, squealing at one pulley. The springs are the ones that came with the door decades ago, orange with rust where they hang near the back wall.
Extension springs are common on the detached garages behind older houses, where a low ceiling left no room for a torsion shaft, and those garages are rarely heated. Damp summers, hard frosts and salt carried in on the car pit the spring wire over the years, and a fatigued spring most often lets go on a cold morning when the steel is stiffest. Replacement fits a new pair rated for the door, renews the pulleys and cables that have rusted alongside them, adds containment cables where the original installation never had any, and leaves a door that lifts easily by hand when the power is out.

Extension Spring Replacement · Rosemount

Scene 1
A spring rarely fails on its own, so the first look ends with the door it was lifting. The technician checks the rollers for cracked wheels and bent stems, the hinges for splits, the track for a bend or a bracket pulled off the jamb, and the bottom section for a dent that catches. The opener's force setting is noted, since an opener turned up to compensate for tired springs will overpower the new ones. And the history matters: a door recently fitted with insulation panels or windows weighs more than the springs were chosen for, and a door that has been closed onto snow or a bin has had its cables jolted.
Scene 2
The initial tension is set with the door open and clamped, so the technician is adjusting slack springs rather than loaded ones. Each cable's S-hook is placed in a hole on the hanger, or its clip set to a mark, and the two sides are put at the same position. The cables are drawn to the same snugness so that neither corner of the door is being pulled ahead of the other. A level across the top section confirms the door is square in its tracks. Only when both sides read the same do the clamps come off and the door come down for its first balance check.
Scene 3
Your door now has a cable running through the middle of each spring, anchored at the back hanger and at the front of the track. It carries no meaningful load while the springs work, though a trace of slack as the door cycles is normal. Its job begins only if a spring ever breaks, when it holds the pieces on the cable instead of letting them fly. It should not be removed, used to hang anything, or tied back to the wall. If it ever looks badly slack, frayed or pulled from its anchor, call to have it corrected promptly rather than waiting for a routine visit. A home inspector looks for this cable when a house is sold.

Yes. The last steps of the visit are the balance test by hand, several full cycles under power and the opener's reversal checks, so the door is ready for normal use when the technician leaves. New springs need no settling period. It is worth running it yourself once or twice while the technician is still there, so you know what a properly balanced door sounds and feels like from now on.
Sometimes, and it is worth asking. A torsion system needs room above the door opening for its shaft and a header that can carry the spring bracket, which many older garages with a low ceiling simply lack; extension springs are there for that reason. Where the headroom exists, a conversion is a separate job with its own hardware and quote. The technician can tell you on the spot which route suits your garage.
The two springs are the same age and have stretched the same number of times, so the one still hanging is close behind. There is also a balance reason: a door lifts level only when both sides pull equally, and a new spring beside a worn one lifts its corner first and twists the door. Fitting a matched pair sets both sides the same and avoids a second visit a few months on.
