Garage Door Spring or Cable Broken: What Happens Now
A bang from the garage, a door that suddenly weighs a tonne, or a cable hanging in a loop. What has happened, and why this repair is not one to attempt yourself.
Quick Answer
If a garage door spring has broken, the door has lost the counterbalance that made it liftable. On a sectional door there is a gap in the coil above the opening; on a roller door the curtain will not lift. A broken lift cable looks different: one side hangs lower and a steel cable is slack or off its drum. Either way, stop using the door, switch the opener off and keep people clear. Springs hold serious tension, so replacement is a job for a technician; we do it across Perth.
Common Causes
Springs wear out by cycles
Every open and close counts, and each spring is made for a limited number. A busy household gets there sooner, and the estate homes of Ellenbrook and Canning Vale built around 2000 are reaching that point now.
Rust and salt air
Moisture and salt eat into coils and cable strands. Homes near the ocean, from Yanchep down to Mandurah, go through springs and cables sooner than inland suburbs.
Wrong spring for the door
A spring sized for a lighter door, or one spring where a double door needs two, works too hard from the start. Proper spring repair begins with weighing and measuring the door.
Cables fray, then snap
Lift cables wear where they wrap the drum and at the bottom bracket; one broken strand snags on the next wrap. When a cable goes, that side drops. Cable repair and replacement does both sides as a pair.
One failure drags in the other
When a torsion spring breaks mid-travel, the drums spin free and the cables jump off. That is why the job is often both, and why forcing the door afterwards makes it worse.
No servicing
Dry, unlubricated springs work harder and rust faster. A yearly check of spring tension, cable wear and door balance catches most of these early.
What You Can Check Safely
Safe to check yourself
- Keep the door closed and the opener switched off at the wall until it has been looked at
- From the floor, look for a gap in the spring coil above the door, or on a tilt door a spring detached at one end
- Check both sides for a cable that is slack, frayed or hanging off its drum
- See whether the door sits level; one corner higher means one side has lost its lift
- If you must get the car out, ask us before touching the release cord
Do not attempt
- Do not lift a door with a broken spring, by hand or with the opener; a double sectional is too heavy for two people and will not stay up
- Do not unwind, adjust or remove a torsion spring or its winding cones — the stored tension is what injures people
- Do not re-hang a cable on its drum; the drum is under spring load and spins the moment the cable frees
- Do not keep pressing the opener button; lifting dead weight strips its gear within a few tries
When to Call a Technician
Call a technician straight away if any of the following apply:
- A loud bang from the garage, then the door would not lift
- A visible break or gap in a spring
- A cable slack, frayed or off the drum
- The door crooked or jammed in its tracks
- The opener straining, stopping and reversing on the way up

Frequently Asked Questions
Stop using the door, switch the opener off at the wall, and keep children, pets and cars away from the opening. Do not pull the release cord or try to lift it. If the door was open when the spring went, leave it open rather than bringing it down. Then call: with the right spring and winding bars it is a routine job, and without them a dangerous one. We rebalance the door and check the opener's force settings on the same visit.
Not safely, and usually not at all. The spring carries most of the door's weight so the motor only has to guide it. Without it a double sectional is dead weight and the opener strains, stalls and strips its gear. Some single doors will still crawl up on the motor, which tempts people to keep using them, but every cycle wears the opener and the door can drop without warning.
You can, but on a two-spring door we recommend both. They were fitted together and have done the same cycles, so the survivor is not far behind. A fresh spring beside a tired one balances the door unevenly and usually means a second callout within months. Single-spring doors obviously get one. We give you both options and prices first, and our garage door springs guide explains the reasoning.
Almost always. A spring is a wear part, and replacing it puts a sound door back into full service for a small share of what a new door costs. The exceptions are a door that is rusted through, badly buckled, or old enough that its panels and track are finished as well; then the money is better spent on a new door. We will tell you plainly which side of that line yours is on.
The spring sets most of it: torsion or extension, one or a pair, the size and wire gauge the door needs, and whether cables and bearings are replaced too. Door type and size, access, and whether you need us after hours shift it further. We price after measuring the door and before starting, and the spring replacement cost guide lays out typical jobs. There is no call-out fee.
Look up, then look sideways. A broken torsion spring shows as a gap in the coil above the door, and the whole door feels evenly heavy. A broken or slipped cable shows on one side: that side sits lower, the door hangs crooked, and a length of cable is slack or loose on its drum. A spring break often throws the cables too, so finding both is common.
