Garage door springs are the hardest-working component in your entire door system — and the one most likely to fail without warning. The short answer: standard torsion springs last around 10,000 cycles, which translates to 7-12 years for the average Sydney household. Here’s how to tell where your springs are in their lifespan, the warning signs of imminent failure, and what to do when they go.
Spring Lifespan by the Numbers
Springs are rated in cycles — one cycle is one complete open and close. The maths is simple:
| Daily Usage | Cycles Per Year | 10,000-Cycle Spring Lasts |
|---|---|---|
| 2 cycles/day (single driver) | ~730 | ~13 years |
| 4 cycles/day (average family) | ~1,460 | ~7 years |
| 6-8 cycles/day (busy household) | ~2,500 | ~4 years |
High-cycle springs (25,000+ cycles) are available and cost only marginally more — worth asking about if your garage is your main entrance.
Torsion vs Extension Springs
Torsion springs mount horizontally above the door and twist to lift it. They’re standard on modern sectional doors, last longer, and fail more safely (the broken spring stays on the shaft). Extension springs run along the horizontal tracks and stretch to lift the door — older technology, shorter lifespan, and when they snap they can whip across the garage unless fitted with safety cables. If your door still runs extension springs without safety cables, upgrading is strongly recommended.
5 Warning Signs Your Springs Are Failing
1. The door feels heavy
Springs counterbalance 95% of the door’s weight. When they weaken, the motor strains and manual lifting becomes noticeably harder. Test: pull the release cord and lift the door halfway — it should stay put. If it slides down, the springs are losing tension.
2. The door opens unevenly or slowly
A door that hesitates, jerks, or rises crooked often has one spring weaker than the other (on two-spring setups).
3. Visible gaps, rust, or stretched coils
Inspect the spring above your door. Healthy coils are tight and uniform. Rust accelerates fatigue dramatically — Sydney’s coastal humidity makes this a real factor, especially in the Eastern Suburbs and Northern Beaches.
4. Loud creaking or popping when operating
Springs nearing end of life make more noise as coils bind and shift. See our guide on diagnosing garage door noises.
5. The door slams shut faster than it used to
Weak springs can’t slow the door’s descent. If your door drops the last half-metre, the springs need attention before something — or someone — gets caught underneath.
When a Spring Snaps: What It Looks Like
You’ll usually hear it — a single loud BANG from the garage, often compared to a gunshot or firecracker. Afterwards: the door won’t open (or opens a few centimetres and stops), the opener strains, and you’ll see a clear 5-8cm gap in the spring coil. Stop using the door immediately. Operating a door with a snapped spring burns out the motor and risks the door falling.
Why You Should Never Replace Springs Yourself
A wound torsion spring stores enough energy to lift a 100kg+ door — releasing that tension incorrectly can cause severe injuries. Professional replacement uses winding bars, proper spring gauges matched to your door’s exact weight, and takes about an hour. In Sydney, professional spring replacement costs $250-$450 including parts — see our full cost guide. Cheap insurance compared to an emergency room visit.
How to Make Your Springs Last Longer
- Lubricate twice a year with silicone-based garage door lube — dry springs fatigue faster.
- Keep the door balanced — an annual tune-up catches tension drift early.
- Replace in pairs — on double-spring doors, when one goes, the other has the same mileage. Replacing both saves a second call-out within months.
- Consider high-cycle springs if you open the door 5+ times daily.
Frequently Asked Questions
Can I use my garage door with a broken spring?
No. The motor isn’t designed to lift the door’s full weight and will burn out, and the door can fall unexpectedly. Park outside and book a repair — most Sydney spring replacements are done same-day.
Should I replace both springs if only one broke?
Yes, on two-spring doors. Both springs have identical wear, so the second typically fails within months. Replacing both in one visit costs far less than two separate call-outs.
How much does garage door spring replacement cost in Sydney?
Torsion springs: $250-$450. Extension springs: $200-$380. Prices include parts, labour, balancing, and safety inspection, backed by our 1-Year Labour Warranty.
Do garage door springs need maintenance?
Just lubrication twice a year and an annual balance check. That alone can add years to spring life, especially in humid coastal suburbs.
