Broken Garage Door Spring? Signs, Repair Cost & What to Do Now
A broken garage door spring is one of the most common garage door failures, and it usually happens without warning: a loud bang from the garage, and suddenly the door won’t open or feels impossibly heavy. This guide shows how to tell if a spring broke, what a broken spring looks like, what to do right now, and what broken garage door spring repair costs in Gilbert in 2026.
How to tell if your garage door spring broke
The springs hold almost all of the door’s weight. On most doors they sit on a bar above the opening (torsion springs); on older doors they run alongside the horizontal tracks (extension springs). When one breaks, you’ll usually notice several of these at once:
| Sign | What it means |
|---|---|
| A loud bang from the garage | The spring snapped and released its tension all at once |
| A gap in the coil of the spring above the door | A 2–3 inch separation confirms a broken torsion spring |
| The door won’t lift or feels extremely heavy | Nothing is counterbalancing the door’s weight |
| The opener lifts it a few inches, then stops | The opener’s safety limit trips against the extra weight |
| The door hangs crooked | One side dropped: a spring on one side, or a broken cable |
What does a broken garage door spring look like?
Look from the floor; don’t touch anything. On a torsion spring, a break shows as a clear gap where the coil has separated, with the two halves of the spring sitting apart on the bar. On an extension spring door, you may see a spring hanging loose or stretched out along the track, held only by its safety cable.

Garage door spring broken on one side?
Many doors have two torsion springs on the same bar. If only one breaks, the other may still lift the door partway, so the door can feel heavy and move slowly or unevenly rather than not at all. Don’t keep using it: the remaining spring is now carrying a load it wasn’t sized for, and it’s usually the same age as the one that failed.
On an extension spring door, a spring broken on one side makes the door lift crooked, which can twist it in the tracks or throw a cable. In both cases, the fix is to replace the springs as a matched pair.
What to do right now
1. Don’t run the opener. Pressing the button against a door with a broken spring can strip the opener’s gear or burn out the motor.
2. Don’t pull the emergency release and lift it. Without the spring the door can weigh 150–250 lb and can drop fast. Here’s more on whether you can open a garage door with a broken spring.
3. Keep everyone clear of the door, especially kids and pets.
4. If your car is trapped and you need it today, ask for a same-day visit. See our emergency garage door repair guide for what counts as urgent.
5. Book the repair and mention whether you see one spring or two above the door; it helps the tech bring the right parts.

How a pro repairs a broken spring
1. Secures the door so it can’t move.
2. Safely unwinds and removes the broken spring (and the matching spring, if replacing both).
3. Fits new springs sized to your door’s weight and height, and winds them to the correct tension.
4. Checks the cables, drums, and bearings, which often take a hit when a spring snaps.
5. Tests the door’s balance and the opener’s auto-reverse before leaving.

Most broken spring repairs take about one to two hours once the technician is on site with the right springs.
Why you shouldn’t replace a spring yourself
Garage door springs are wound under enormous tension, enough to cause serious injury if a winding bar slips. They’re consistently ranked among the most dangerous DIY home repairs, and the wrong spring size or wind count throws the door out of balance and wears out the opener. This is a job for a technician, and usually a quick one.
Replace one spring or both?
If your door has two springs and one broke, replace both. They’ve done the same number of cycles, so the second is usually close behind, and replacing them together keeps the door balanced and avoids a second service call. Most standard springs are rated for about 10,000 cycles, roughly 7–12 years of normal use; see how long garage door springs last in Arizona’s heat. If you use the door many times a day, ask about high-cycle springs.
Why garage door springs break
Most springs simply wear out: every open and close is one cycle, and the steel fatigues over time. Rust, dry springs, an unbalanced door, and Gilbert’s big temperature swings all shorten their life. A yearly garage door tune-up won’t make springs last forever, but it catches a worn spring before it leaves you stuck. Our garage door maintenance service includes a spring and cable check.

Frequently Asked Questions
How much does it cost to fix a broken garage door spring?
In Gilbert, replacing a single broken torsion spring typically costs $150–$300, and replacing both springs costs $250–$500. Extension spring pairs run about $130–$250. After-hours visits usually add $50–$150.
How can I tell if my garage door spring is broken?
Common signs are a loud bang from the garage, a visible gap in the spring above the door, a door that won’t lift or feels extremely heavy, an opener that lifts the door a few inches and stops, or a door hanging crooked.
Can I open my garage door with a broken spring?
You shouldn’t. Without the spring the door is very heavy and can drop suddenly, and running the opener against that weight can damage the motor. Leave the door closed until the spring is replaced.
Is a broken garage door spring dangerous?
Yes. The spring stores a lot of energy, and a door without a working spring can fall unexpectedly. Most injuries happen when people try to lift the door or replace the spring without the right tools.
What if the garage door spring broke on only one side?
With two torsion springs, the remaining spring may still lift the door partway, but it’s overloaded and usually close to failing too. On extension spring doors, one broken side makes the door lift crooked. Stop using the door and replace the springs as a pair.
How long does broken spring repair take?
Most broken spring repairs are same-day and take about one to two hours once the technician is on site with the correct springs.
Should I replace both garage door springs at once?
If your door uses two springs, yes. They wear at the same rate, so replacing both keeps the door balanced and avoids a second repair soon after.
Why did my garage door spring break?
Usually from age and use: springs are rated for a set number of cycles, typically about 10,000. Rust, lack of lubrication, an unbalanced door, and Arizona’s temperature swings can shorten that life.
