- The call
- You pulled the red cord to open the door during a power cut and it barely moved. Lifting it took your whole weight, and when you let go it came down hard. It used to float up with one hand.

In plain words
Every extension spring should carry a containment cable, and replacement is the moment to make sure yours do. A containment cable runs through the centre of the spring and is anchored at both ends, to the rear hanger and to the bracket at the front of the track. It does no lifting; its purpose is to hold a spring that breaks so the pieces stay on the cable. Many older doors predate this practice, which a home inspection checklist checks for. When springs are replaced, new containment cables are fitted with them, which keeps a broken spring's pieces contained, not the door's weight, balance or safety.

How the visit goes
Scene 1
Both springs, side by side
Even when only one spring has snapped, both are read closely. The technician looks for gaps opening between coils with the door up, which means the wire has stretched and lost its pull; rust pitting and scale, especially where the spring sits nearest the back wall; a spring hanging visibly longer or lower than its partner; and end loops that have opened or cracked. The two are compared for length, coil diameter and wire size, because springs of different ratings are sometimes found on the same door after a past repair. Whatever is found, the outcome is the same, a new matched pair, but the reading tells the technician what rating the door really needs.
Scene 2
Balancing the door by hand
Balance is judged with the opener still disconnected. The technician lowers the door to the floor, then lifts it: it should rise with modest effort, stay put when let go at about waist height, sit steady when fully open, and come down under control rather than dropping. If it sinks, both springs need a little more stretch and each S-hook is moved one hole to take up cable; if it climbs on its own, one hole the other way. Adjustments are always made in pairs, with the door open and clamped again each time, so the two springs stay equal. Two or three rounds usually settle it.
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 quoteBedford Park Garage Door Experts
- Hangers and anchor points
- A rear hanger that has loosened, a front bracket bent by a jumped cable, or framing that needs a new anchor point adds fasteners, angle iron and a little time.
- Pulleys that need renewing
- Each side has two pulleys, and a wheel worn to a groove or a bearing that has stiffened is replaced with the springs. The quote names how many and which type.
- One spring per side or two
- Heavier doors sometimes carry a pair of springs on each side rather than one. Four springs, four containment cables and the extra setting time show as their own lines.

What to expect, in questions
Is it all right to keep shelves and storage near the springs?
Keep a clear zone around them. The springs, pulleys and cables move on every cycle, and anything leaning into their path, such as a ladder, a hockey bag or a shelf edge, can catch a cable or knock a pulley. Storage that crowds the rear hangers also slows any future service. A hand's width of clear air around each spring's full travel, and nothing hung from the springs or their cables, is the rule of thumb.
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.
Will the lift cables be changed as well?
They are inspected every time and changed when they show fraying, rust at the bottom loop, or a kink from having jumped a pulley. Cables and springs are generally the same age, and with the door already open and the springs off, fitting new cables adds little to the visit. Bright, tight strands with clean loops can stay and are simply re-routed over the pulleys and set to the new springs.
Springs & Hardware
- Garage Door Hinge ReplacementOn the old wood door, one hinge has pulled away from the panel, dragging a screw and a chunk of soft timber with it.
- Garage Door Track Repair or ReplacementThe door climbs crooked, one side clearly ahead of the other.
- Garage Door Cable ReplacementThe car bumper kissed the door on the way in.
- Torsion Spring ReplacementThe door starts to rise, gets about the height of your knee, then shudders and reverses.
- Garage Door Balance AdjustmentWith the door closed, daylight shows under one bottom corner and the seal is squashed flat at the other.

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.In a mature neighbourhood the garage door is often the single largest feature of the front elevation, so keeping the original look matters. Modern insulated doors come in raised-panel and carriage styles that echo the older designs while running on today's torsion hardware.
- Single-detached houses make up about 23% of homes in Toronto (2021 Census).Where housing is mostly attached, the common garage entrance may be a rolling grille or heavy sectional door with access by fob or remote, managed by the property. We service these operators, safety edges and photo-eyes, and coordinate with management so residents keep their access throughout.
