- The call
- The opener groans on the way up and the door slams the last foot on the way down, hard enough to rattle the windows. The motor is the same one it always was; something in the springs has stopped doing its share.
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.
In plain words
When one extension spring breaks, the other is replaced with it. The two springs were fitted together, have stretched the same number of times and have rusted in the same air, so the survivor is near the end of its life. More importantly, a door balances only when both sides pull equally; a new spring paired with a tired one lifts one corner ahead of the other and twists the door. Fitting a matched pair rated for the door's weight lets the technician set both sides to the same hook position and hand back a door that rises level and holds where it is left.

How the visit goes
Scene 1
Securing the door with the springs slack
An extension spring is stretched tight when the door is closed and nearly relaxed when the door is fully open, so the first move is to get the door up. The technician pulls the opener's release, raises the door by hand if it will go, and clamps both vertical tracks below the bottom rollers so the door cannot come down. If a broken spring has left the door stuck partway, it is lifted and supported with the weight taken on clamps and props before anything else is handled. With the door held open, the springs, pulleys and hooks can be examined and removed like ordinary hardware, which is the whole reason the sequence begins this way.
Scene 2
Running the lift cables
Each lift cable starts at the bottom bracket, where its loop goes over the pin or is secured with a clevis pin. From there it runs up the vertical track, over the fixed pulley at the front of the horizontal track, back along the track to the pulley on the end of the spring, around it, and forward again to the S-hook or adjusting clip at the front hanger. The technician keeps the cable seated in each pulley groove and makes sure it passes on the correct side of the containment cable and the track. Cables are renewed if the old ones showed any fraying or rust, and always as a pair of the same length.
Scene 3
Checking the balance yourself
You can confirm the springs are still doing their share without going near them. With the door closed and nobody in the opening, pull the opener's red release cord so the trolley lets go of the door. Lift the door by its handle to roughly hip height and take your hands away. A door on good springs stays about where it is; if it sinks to the floor the springs have weakened, and if it rises on its own they are pulling harder than the door weighs. Either way it is a call rather than a job for you. Reconnect the opener the way your manual describes, usually by running it once.

What shapes the quoteArmour Heights Door Specialists
- Condition of the lift cables
- Cables with fraying, rust at the loop or a kink are renewed as a pair while the springs are off. Sound cables are re-routed and set, and the quote says which applies.
- Rollers, hinges and bottom brackets found worn
- Cracked roller wheels, split hinges or a bottom bracket rusted at the cable pin are pointed out during the inspection and offered as optional items, since the door is already open and secured.
- Corroded fasteners
- In an unheated garage the bolts through pulley forks and hanger brackets rust solid; freeing or cutting them and fitting new hardware takes time and shows in the parts list.

Asked and answered
Do the pulleys need replacing at the same time?
Often, yes. Each side has two pulleys, one on the spring and one fixed at the front of the track, and the cable rides over both on every trip. A pulley whose wheel has worn a sharp groove, or whose bearing has stiffened, drags on the cable and adds load the spring has to overcome, which is a common reason the old spring wore early. Pulleys that spin freely and run true can stay.
Why does the opener get adjusted after new springs?
Because the door is now much lighter for the opener to move. Over the years, as the old springs weakened, the opener's force setting may have been turned up to keep the door going, and its travel limits were set against a door that sat differently on the floor. Left alone, that extra force would push the newly balanced door too hard. Resetting force and travel, then repeating the reversal tests, matches the opener to the door it now has.
Can I keep using the opener until the spring is replaced?
It is better to leave the door where it is. With one spring gone, the opener is lifting most of the door's weight on its own, which strains the motor, can bend the top section and often throws a cable off its pulley, adding to the work. Use another door in and out, keep the bay clear, and let the technician move the door once it is secured.

2021 census: what it means at the door
Every square is one home in a hundred.
- 58 in 100 homes · older homes
- 23 in 100 homes · mostly attached
- About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.Where houses are older, the garage often sits beside the house rather than beneath a bedroom, so noise is a smaller concern and durability a larger one. Heavy-duty rollers, a properly sized torsion spring and cold-rated lubricant make an old door dependable for years.
- Single-detached houses make up about 23% of homes in Toronto (2021 Census).Apartment and condo buildings often have a single heavy door protecting the whole parking level, and when it stops, everyone is affected. We prioritise these calls, carry commercial operator parts, and set up a maintenance interval matched to the number of cycles the door sees each day.
