Your Garage Door Spring Broke — Now What?

It usually announces itself. A bang from the garage, loud enough to sound like something heavy falling, followed by a door that will not open, opens a few inches and stops, or suddenly feels far heavier than it did yesterday. That is a broken garage door spring, and the first hour after it happens is when most of the avoidable damage — and most of the risk — occurs. People keep pressing the remote, try to force the door by hand, or reach for tools, and each of those moves can turn a straightforward repair into a damaged opener, a dropped door, or an injury.

This guide covers what to do right now, what not to do, how to get a car out if you genuinely need to, and what a spring repair actually involves, so you can make calm decisions instead of rushed ones.

How to Tell a Spring Has Broken

Several signs point to a spring fault, and they often arrive together. The most obvious is the sound: a torsion spring snapping releases its stored energy at once, producing a sharp bang. After that, the door may not open at all, or it may rise a few inches and stop as the opener senses too much resistance and reverses. A door that opens unevenly, with one side lifting before the other, or a door that slams down faster than usual, can also indicate a spring problem.

Look at the spring itself, without touching it. Torsion springs sit on a bar above the door; extension springs run along the sides, parallel to the tracks. A clear gap between the coils of a torsion spring is the surest visual sign of a break. Rust, visible stretching on one side, or a spring that looks longer than its partner are warning signs that a spring is near the end of its life even if it has not snapped yet. Springs are typically rated for 10,000 to 20,000 open-and-close cycles, which works out to roughly 7 to 14 years of normal use, so a spring on an older door that starts behaving differently deserves attention before it fails outright.

A broken spring can also show up indirectly. If the opener hums, strains, or clicks without lifting the door, or if the door feels dramatically heavier when lifted by hand, the spring is no longer carrying its share of the weight. That is the key point to grasp: the spring does the lifting, and the opener mostly guides the door. Without a working spring, the opener is trying to lift the door's full weight, which it was never designed to do.

The First Five Minutes: Stop and Secure

The single most important step is also the simplest: stop pressing the remote. Every attempt to run the opener on a broken spring strains the motor, can strip its internal gears, and risks bending the door or snapping a cable as the door moves unevenly. One failed attempt is information; repeated attempts are damage.

Next, keep people and pets clear of the door, and leave the door where it is if you can. A closed door is the safest position: it cannot fall further, and nothing can pass under it. Do not try to prop a partially open door in place with timber, tools, or boxes. A door without a working spring is unbalanced, and a prop can slip, letting the door drop without warning. If the door is stuck open, keep the area underneath clear and treat the opening as unsafe to walk through until the door is secured by a technician.

Do not touch the spring, the cables, or the brackets that hold them. All of them are under extreme tension even when the door is closed, and a slipping tool or a released cable can cause severe injury. This is not a repair where watching a video first makes it safe: spring work needs specific tools, specific training, and a feel for tension that cannot be picked up in an afternoon. The same applies to cables, which run under the same tension and can whip or release suddenly if disturbed.

If Your Car Is Trapped Inside

Sometimes leaving the door closed is not an option, because the car is inside and you need to leave. There is a way to get the car out, but it needs care, and it is not suitable for everyone or every door.

First, pull the red emergency release cord on the opener to disconnect the trolley from the door. Then lift the door slowly by its handle, ideally with a second person for a double-width door, because without a spring you are lifting the door's full weight — often 150 pounds or more. Keep hands and feet clear of the door's path, lift steadily without jerking, and lower the door fully again once the car is out. Do not leave the door half-open, do not prop it, and do not reconnect the opener and try to run it: the opener will strain against the same weight that just defeated it.

If the door will not lift even with two people, if it drops as soon as you let go, if it racks sideways as it rises, or if a cable looks loose or frayed, stop. A door that cannot be lifted safely by hand should not be forced. In that case, leave the car where it is and call for a repair: a technician can secure the door and get it moving again far more safely than a forced lift.

The same caution applies in reverse. If the door is stuck open and you need to close it for security, lower it slowly by hand with help, keeping clear of its path, and do not use the opener to drive it down. A door closing under its own unbalanced weight can slam, and a slamming door can jump its tracks or damage its panels.

Torsion Springs, Extension Springs, and Why Both Matter

Most residential doors use one of two spring types, and knowing which you have helps you describe the fault accurately when you call. Torsion springs are mounted on a metal bar above the door opening. They twist as the door closes, storing energy, and unwind as the door opens. They are generally more durable, and they tend to fail with a single loud snap and a visible coil gap.

Extension springs run along the horizontal tracks on either side of the door and stretch as the door closes. They are common on older or lighter doors. Extension springs should have safety cables running through them, which catch the spring if it breaks and stop it flying across the garage. If your extension springs have no safety cables, mention that when you call: it is a safety item a technician can address during the same visit.

When one spring breaks on a two-spring door, technicians usually recommend replacing both springs at the same time. The reasoning is simple: both springs have done the same number of cycles in the same conditions, so the surviving spring is close to the same age and wear. Replacing only the broken one leaves an old spring carrying a new partner, and the old one often fails soon afterwards, meaning a second call-out for what could have been one visit.

What a Spring Repair Visit Actually Involves

A spring repair is not just a spring swap.

First, the technician secures the door and releases any remaining tension safely, using winding bars and the correct procedure for the spring type. Then the broken spring is removed and the new spring — matched to the door's weight, height, and track configuration — is fitted. The technician winds the new spring to the correct tension, which is measured in turns and checked against the door's balance: a correctly tensioned door should stay roughly where it is left when lifted to waist height by hand, neither dropping nor shooting upward.

After the spring itself, the technician should check the parts that work with it. Cables are inspected for fraying and correct winding on the drums. Rollers, hinges, and bearings are checked for wear that would drag on the new spring. The tracks are checked for alignment, and the opener is tested through full cycles, including the safety-reverse test. If the opener was run repeatedly on the broken spring before the repair, the technician should also check its gears and drive mechanism, since that strain can leave damage that shows up later.

Finally, the door should be run through several full open-and-close cycles before the technician leaves, with even movement, no new noises, and both safety tests passing.

What Spring Replacement Typically Costs

Spring replacement typically runs $200 to $350, within the broader range of $150 to $600 for most garage door repairs published on this site. The figure depends on the spring type, whether one or both springs are replaced, the door's size and weight, and whether related parts such as cables or rollers need attention in the same visit. A visit that replaces both springs and worn cables will cost more than a single-spring swap, but it addresses the parts most likely to fail next, which is usually the better value over the following year.

Be wary of any approach that prices the job without seeing the door, or that treats the spring as the only part worth checking. The spring, cables, drums, rollers, and opener work as a system, and a price that ignores the rest of the system is likely to grow once work starts. A technician who inspects the whole door before quoting is doing the job properly, not padding it.

Garage Door Repair Pros connects callers to local providers for spring repair. If your spring has broken, call (210) 964-8892, 24/7, and tell the dispatcher whether you have one spring or two, whether the door is stuck open or closed, and whether you heard a bang. That detail helps the technician arrive with the right parts on the first visit.

Preventing the Next Break

Springs fail from cycles, not from neglect alone, so no maintenance routine makes a spring last forever. But a few habits stretch spring life and, more importantly, catch a failing spring before it snaps without warning.

Lubricate the spring coils twice a year with a garage-door-rated silicone or lithium-based lubricant, following the door manufacturer's instructions. Lubrication reduces friction and slows rust, which is one of the main accelerators of spring fatigue, especially in humid or coastal conditions. While you are there, look at the springs for rust, gaps, or stretching, and listen for new squeaking or popping during a full cycle — both can precede a break by weeks.

Work through a full maintenance routine twice a year as well. The checklist in Garage Door Maintenance Checklist: 12 Things to Check Twice a Year covers balance, cables, rollers, tracks, and both safety tests. A yearly garage door maintenance visit from a local technician covers spring tension and cable condition.
