When a garage door spring breaks, the first question most people ask is “what’s this going to cost me?” It’s a fair question, and an honest answer is: it depends. The cost of a spring replacement isn’t a single fixed figure, because no two doors are exactly alike. What we can do is explain the factors that determine the cost, so you understand what you’re paying for — and how to get a free, no-obligation quote for your own door.
We’re Filip and Kelly Kulinicz, and we run Filip’s Garage Doors out of Goolwa, serving homes across the Fleurieu Peninsula and southern Adelaide. We replace garage door springs regularly, and we believe in being upfront about how pricing works rather than quoting a number that may not reflect your situation.
What a Garage Door Spring Actually Does
The springs on your garage door do the heavy lifting — literally. A garage door is heavy, and the springs counterbalance that weight so the door can be raised easily, whether by an opener motor or by hand. When a spring fails, that balance is lost. The door suddenly feels far heavier, the opener struggles or won’t lift it at all, and the door can become unsafe to operate.
Because the spring carries so much load, it’s a part that wears with use. Every open and close cycle puts the spring through its work, so springs do have a finite life. A failed spring is one of the most common garage door repairs we attend.
Torsion Springs vs Extension Springs
There are two main types of garage door spring, and which one your door uses affects the job.
- Torsion springs sit on a metal shaft above the door opening and wind up as the door closes. They’re common on heavier sectional and panel-lift doors.
- Extension springs run along the horizontal tracks on either side of the door and stretch as the door closes. They’re more often found on lighter doors.
The type, size, and number of springs your door needs all feed into the work involved, which is part of why a quote is specific to your door.
Signs of a Broken or Worn Spring
You don’t always have to wait for a complete failure to know a spring is on the way out. Common signs include:
- The door won’t lift, or the opener strains and stops partway.
- You heard a loud bang from the garage — a torsion spring failing can make a sound like a firecracker.
- The door feels very heavy when you try to lift it by hand.
- There’s a visible gap in the coil of a torsion spring above the door, where it has snapped.
- The door opens unevenly or looks crooked.
If you notice any of these, it’s worth having the door looked at sooner rather than later — a door running on a worn or broken spring puts extra strain on the rest of the system, including the cables and the opener.
What Affects the Cost of a Spring Replacement
Rather than quote a figure that might be wrong for your door, here are the things that genuinely move the cost up or down:
- The type of spring. Torsion and extension springs are different parts and involve different work.
- The size and weight of the door. A larger, heavier door needs heavier-duty springs.
- How many springs need replacing. Some doors run on a single spring, others on a pair. Where there are two, it often makes sense to replace both at once, since they’ve done the same amount of work and the second is likely to follow the first.
- The parts required. The specific spring rating and any related hardware that needs attention.
- Access. How easy it is to get to and work on your particular door and opener.
The most reliable way to know what your repair will cost is to have us take a look. We’ll assess the door, confirm exactly what it needs, and give you a clear quote before any work starts — with no surprises.
Why a Broken Spring Is a Safety Risk
This is the part we can’t stress enough. Garage door springs are under enormous tension — they have to be, to counterbalance the weight of the door. When you try to wind, adjust, or replace a spring without the right tools and training, that stored energy can release suddenly and cause serious injury.
This is genuinely one of the jobs we’d ask you not to attempt yourself. It isn’t a matter of saving a bit of money — a spring under load is dangerous, and so are the cables that work alongside it. Always have spring work done by a licensed technician. We’re licensed builders (BLD 188 315) and we carry the right gear to do it safely.
If you think you have a broken spring, stop using the door. Don’t keep pressing the opener button, as you can damage the motor by forcing it against a door it can’t lift.

Frequently Asked Questions
Why can’t you tell me an exact price over the phone?
Because the cost depends on your specific door — the type and number of springs, the door’s size and weight, the parts required, and access. We’d rather assess it properly and give you an accurate quote than guess and get it wrong. The assessment and quote are free, with no call-out fee.
Should I replace both springs if only one has broken?
If your door runs on a pair of springs, it’s often worth replacing both at the same time. They’ve done the same amount of work, so once one fails the other is usually not far behind. We’ll talk you through what makes sense for your door when we quote, and the choice is always yours.
Can I replace a garage door spring myself?
We’d strongly advise against it. Garage door springs are under extreme tension and can cause serious injury if they release while you’re working on them. It’s a job for a licensed technician with the right tools. If you have a broken spring, stop using the door and give us a call on (08) 8555 4269.
