Garage Door Spring Repair and Replacement in Adelaide

Garage door spring repair replaces a snapped or tired torsion or extension spring so the door lifts safely again. We replace springs across metro Adelaide. A single torsion spring is typically $220 to $320, a pair $360 to $480 and extension springs $260 to $420. Don't run the motor; request a quote through our form and mark it urgent.

A snapped torsion spring is the single most common garage door fault we see in Adelaide. The springs (one or two coils sitting horizontally above the door) wind up to store the energy needed to lift the 60-90kg door. They have a typical life of 10,000-15,000 cycles — about 7-12 years for a daily-use residential door, sometimes much shorter for a high-cycle commercial door.

When a spring fails it usually goes with a loud bang. The door becomes essentially un-liftable by the motor (the motor is sized to assist the springs, not to lift the door alone). The car can be trapped inside or outside depending on the door position.

What it costs

• Single torsion spring replacement: $220-$320
• Pair of springs replaced: $360-$480 (recommended if springs are similar age — replacing one of an aged pair just means the second one fails next year)
• Extension spring replacement (older systems, common on tilt doors): $260-$420
• Cable replacement at the same time: add $180-$340 if cables are also frayed (often the case if the door’s been operating with one snapped spring)

Why both springs at once

If your door has two torsion springs and one’s snapped at year nine, the second one is approaching the end of its cycle life. Replacing both at once means:

• Single call-out fee, single labour charge
• Matched spring tension (better door balance, longer-lived motor)
• No second failure in the next 6-18 months

Most Adelaide technicians quote both springs by default and explain the option of replacing one. The price differential is small enough that the maths almost always favours the pair.

Don’t DIY this

We say this not because we want the work — we say it because torsion-spring replacement is genuinely dangerous. The springs are wound to several hundred PSI under load. Rebound during a botched replacement has caused serious injuries (broken wrists, eye injuries, hand fractures). The job needs purpose-built spring-winding bars and a known-good technique. If you’re a confident DIYer, do the cable replacement; leave the spring tensioning to a technician.

Getting it booked

A snapped spring is one of the highest-priority calls on our schedule. Submit through the quote form and we’ll get back to you within 24–48 hours — mark it as urgent if your car is trapped.

Frequently asked questions

How much does garage door spring replacement cost in Adelaide?

A single torsion spring is typically $220 to $320 and a pair $360 to $480. Extension springs, common on older and tilt doors, are $260 to $420. If the cables are frayed too, add $180 to $340 for a new pair. We confirm a fixed price before starting.

Should I replace both garage door springs at once?

Usually yes, if they're the same age. When one spring in a pair snaps, the other is near the end of its life. Replacing both on one visit costs only a little more, balances the door properly and avoids a second call-out soon after.

Can I open my garage door with a broken spring?

Don't use the motor: the opener is built to assist the springs, not lift the whole door. Don't try to lift it by hand either. Without the spring the door is very heavy and can drop suddenly. Arrange other transport and mark your request urgent on our quote form.

Can I replace a torsion spring myself?

We strongly advise against it. Torsion springs are wound under very high tension, and a slip during winding can cause serious hand, wrist and eye injuries. The job needs proper winding bars and technique, so leave it to a technician.
