The single most common garage door problem
In our service history at Limitless, broken springs account for roughly 40% of all repair callouts. They're the part that does the most work on your garage door — a torsion spring lifts essentially the entire weight of the door panel every time it opens, and over thousands of cycles the steel gradually fatigues until it snaps.
The good news is they're a routine repair when handled by a trained technician. The bad news is that DIY spring replacement is one of the most dangerous things a homeowner can attempt around their house.
How to tell if your spring is broken — 4 checks
Before you call us, run through these four checks so you can describe what's happening. None of them require you to touch a spring.
1. Did you hear a loud bang?
A snapping torsion spring releases its stored energy in a fraction of a second. It's loud, unmistakeable, and it almost always happens overnight or first thing on a cold morning when spring tension peaks. If you've been woken up by what sounded like a gunshot from the garage, your spring has almost certainly broken.
2. Does the door feel extremely heavy?
Pull the red emergency release cord on your opener (this disengages the door from the motor) and try to lift the door by hand. A balanced door with healthy springs will lift easily and hold position halfway up. A door with a broken spring will feel like dead weight — typically 50–110kg of steel — and will crash down if you let go. Do not stand under it. Do not try to operate it with the opener after this test.
3. Is there a visible gap in the spring coil?
With the door fully closed, look at the long horizontal spring(s) mounted above the door opening. A healthy spring is one continuous coil. A broken spring will show an obvious 1–2cm gap somewhere along its length where the metal has snapped clean. If you see this gap, the diagnosis is confirmed.
4. Is the opener straining?
If the opener motor runs but the door barely moves — or the door opens 30cm and then stops — the spring has likely failed. The opener is being asked to lift the entire weight of the door on its own, well beyond its design capacity. Continued use will burn out the opener motor or strip its gears, turning a $290 spring job into a $1,500 spring-and-motor job.
Torsion vs extension springs
Two main spring types are used on Australian residential garage doors:
- Torsion springs — long horizontal springs mounted on a shaft above the door opening. They twist to lift the door. Modern standard. Last longer, operate more smoothly.
- Extension springs — shorter springs mounted along the horizontal tracks on either side of the door. They stretch as the door closes. Older Australian doors often use these. Cheaper to replace, shorter cycle life.
Both can be replaced; both must be replaced by a professional. The risk profile is identical.
Why DIY spring replacement is dangerous
A standard residential torsion spring stores 200–400 foot-pounds of torque. To wind or unwind it you use two hardened steel winding bars inserted into cones at each end of the shaft. If a winding bar slips — which happens to inexperienced operators with depressing regularity — the bar becomes a projectile or your hand becomes a casualty.
Australian emergency departments routinely treat broken fingers, broken wrists, jaw fractures and eye injuries from DIY spring work. Standard household home insurance typically excludes injury from DIY work on tensioned mechanical hardware, and any remaining manufacturer warranty on your door is voided the moment a non-licensed person touches the springs. The $290 a professional charges for the job is genuinely the cheapest part of the equation.
What spring replacement costs at Limitless
- Single torsion spring, supplied and installed: from $290
- Matched pair of torsion springs (recommended): from $390

Every spring job includes a full balance check, cable inspection, roller and hinge lubrication and a written workmanship warranty. We carry standard residential springs on every service van so most jobs are completed on the first visit.
