A broken garage door spring stops your door from moving — and the repair itself usually takes less than an hour once the technician arrives. The actual time depends on the spring type, door size, and what else needs attention while they’re there.
What happens when a garage door spring breaks?
Torsion springs sit above the door on a metal shaft and wind up as the door closes, storing energy to help lift it. When one breaks, that stored energy releases suddenly — you’ll often hear a loud bang from the garage. The door becomes very heavy to lift manually because the spring is no longer counterbalancing its weight. Extension springs run along the sides of the door and stretch to provide lift; when they break, the door may jerk unevenly or hang crookedly. In either case, the opener strains or fails to move the door because it’s trying to lift the full weight without assistance.
How do you know it’s the spring and not something else?
A door that won’t move at all but makes no sound when you hit the wall button often points to the opener or power — check the outlet and circuit breaker first. If the door moves a few inches then stops or reverses, look at the safety sensors or tracks for obstructions. A door that lifts about six inches then stops hard, or one that slams shut when you try to close it, is almost always a spring issue. You might also see a visible gap in the torsion spring above the door or a dangling piece of extension spring along the track. Noise alone — like squeaking or grinding — usually means rollers, hinges, or lack of lubrication, not a broken spring.
What can you safely check yourself before calling?
Start with the basics: make sure the opener is plugged in and the outlet has power (try a lamp or phone charger). Check if the manual release cord — the red handle hanging from the opener rail — has been pulled accidentally; re-engaging it takes seconds. Look at the photo eyes on either side of the door, bottom corner; wipe them with a dry cloth if they’re dirty and ensure nothing’s blocking the beam. With the door closed, inspect the springs: torsion springs should show no gaps in the coil; extension springs should be intact with no frayed or missing pieces. Do not touch the springs or attempt to adjust them — they’re under extreme tension and can cause serious injury. If the door is stuck open, do not stand underneath it; secure it with clamps or call for help.
Why spring repair isn’t a DIY job
A standard torsion spring for a residential garage door holds enough force to lift 150-250 pounds — that’s the door’s weight — and releases it instantly if unwound incorrectly. Winding bars can slip, sending steel flying at high speed; fingers can be caught in the coils; the shaft can spin violently. Extension springs, while under less torsional force, still store significant energy and can lash out if they break during handling. Richmond’s older neighbourhoods like Steveston and Burkeville have many 1960s-80s homes with original torsion systems — these springs are often at or past their rated cycle life, making failure sudden and replacement urgent. A technician uses proper winding bars, knows how to measure and match the spring’s wire size, length, and inside diameter, and tests the balance afterward to ensure the door stays put when lifted halfway.
What does the technician actually do on site?
First, they secure the door in the down position using clamps on the track to prevent movement. Then they release any remaining tension in the broken spring safely — for torsion springs, this means loosening the set screws and carefully unwinding with winding bars; for extension springs, it’s disconnecting them from the track and pulley system. They measure the old spring to specify an exact replacement: wire gauge, inner diameter, overall length, and wind direction (left-hand or right-hand coil). After installing the new spring, they wind it to the correct tension, test the door’s balance by lifting it halfway to see if it stays put, and adjust as needed. They’ll also check the cables, rollers, hinges, and opener rail for wear — since the door was operating under extra strain or slamming shut, related parts often need attention. Lubricating the springs, hinges, and rollers is standard before they consider the job complete.
What affects how long the repair takes?
Most torsion spring replacements on a standard single or double car door take 45 to 75 minutes from start to finish. Extension spring jobs can be quicker — sometimes 30 to 50 minutes — because they’re more accessible and don’t require winding. Factors that add time include: rusted or seized components needing penetrating oil and extra effort to disassemble; a second spring that’s also worn and should be replaced at the same time (technicians usually recommend replacing both sides for even wear); damaged cables or rollers discovered during inspection; or a non-standard door size requiring special-order springs. In Richmond’s flats like Brighouse or the townhouse complexes near Alderbridge, shared-wall garages or tight access can slow setup slightly, though the core swap remains the same. Weather rarely delays the repair itself unless flooding or extreme conditions prevent safe access to the garage.
How to prevent future spring breaks
Springs fail from cycle count, not age — each full open and close is one cycle. Most residential springs are rated for 10,000-15,000 cycles, which for average use (4 cycles a day) lasts 7-10 years. Richmond’s coastal moisture and occasional cold snaps can accelerate wear on unlubricated springs and cables, but the primary driver is usage. Lubricate the springs three or four times a year with a silicone-based spray — do not use WD-40, as it attracts dirt and doesn’t last. Watch for signs of wear: gaps in the torsion coil, rust, or fraying on extension springs. If your door feels heavier than usual to lift manually or the opener strains more than it used to, have it checked before a break leaves you stranded. Annual service visits catch weakening springs early.
When should you call for help?
If the door won’t move, looks uneven, or you heard a loud bang from the garage, call a technician. Do not attempt to lift or move the door manually if a spring is broken — it can drop suddenly and cause injury or damage. For same-day service in Richmond, BC, call 778-873-7282. Provide your neighbourhood and door size if known — it helps them bring the right springs and tools.
