You were in the kitchen, or maybe in bed, when you heard it: one sharp bang from the garage, loud enough that you checked whether something fell off a shelf. Nothing looks out of place. Then you press the opener button, the motor hums, and the door rises a few inches before it stops, shudders, or refuses to move at all. Look up at the bar running across the top of the door and you will probably see a gap of a couple of inches in the middle of one coiled spring. That gap is the reason your door suddenly weighs as much as it actually does, and what you do in the next hour decides whether this stays a spring repair or turns into a bigger one.
With hundreds of positive reviews across Google, Yelp, HomeAdvisor, and Angi, Door-Mart Garage Doors has been answering broken-spring calls across California for more than 40 years, and the most expensive ones are almost always the doors someone kept trying to open after the bang.
If your spring just broke and you need to get a car out, get the door secured, or understand what happens next, this article walks you through it step by step. For same-day service, call 1-800-829-9833, email info@doormartgaragedoors.com, or request service online.
Quick Answer: What Should You Do When a Garage Door Spring Breaks?
Stop using the opener, unplug it, and keep the door where it is. A broken spring leaves the full door weight on the opener and cables, so repeated attempts can strip the opener gears, snap a cable, or drop the door. Keep people and pets clear, then have a technician replace the springs.
What Does a Broken Garage Door Spring Look and Sound Like?
The sound is the giveaway. A torsion spring holds a large amount of stored energy, and when the steel wire finally fractures, that energy releases in a fraction of a second. Most homeowners describe it as a gunshot or a firecracker inside the garage. It often happens when the door is closed and sitting still, because that is when the spring is wound tightest.
Here is what you will usually see afterward:
- A gap in the coil. On a torsion system (springs mounted on a bar above the door), one spring will have a visible two- to three-inch gap where the wire separated.
- A stretched or snapped extension spring. On older doors with springs running along the horizontal tracks on each side, a broken extension spring hangs loose or is missing a section, and the safety cable running through it is now holding it in place.
- A door that rises a few inches, then stops. Most openers have a force setting that shuts the motor off when it senses too much resistance. A door without spring support trips that setting almost immediately.
- Cables hanging slack. The lift cables at the bottom corners of the door may come loose from their drums at the top once the spring is no longer holding them taut.
- A crooked door. If one of two springs broke, the door may lift unevenly or sit tilted in the opening.
The door itself has not suddenly gotten heavier. A typical residential garage door weighs well over 100 pounds, and a double-car insulated steel door can weigh several hundred. The springs were carrying almost all of that weight every time you opened it. The opener was only ever meant to guide a balanced door, not lift a dead weight.
Why Do Garage Door Springs Break in the First Place?
Springs are a wear item with a finite life, measured in cycles. One cycle is one full open and one full close. The average garage door opens and closes three to five times a day, which puts a typical household somewhere between 1,000 and 1,800 cycles a year. Every one of those cycles twists or stretches the spring wire and lets it relax again, and steel eventually fatigues under that repeated stress.
The most common reasons a spring reaches the end of its life early:
Daily use outpaces the spring’s rating. A household that uses the garage as its main entrance can double the cycle count of a household that parks in the driveway. A spring rated for a set number of cycles simply gets there sooner.
Rust and corrosion. Surface rust creates friction between the coils and pits the wire. A pitted spring fails at the weak point rather than wearing evenly.
The wrong spring for the door. If a previous repair installed springs that are undersized for the door’s weight, each spring works harder on every cycle. This happens often after a door gets heavier through added insulation, windows, or decorative hardware.
An unbalanced door. When one spring is weaker than the other, or the door has not been adjusted in years, the springs and opener carry the load unevenly.
Cold mornings. Steel becomes slightly less forgiving when it is cold, which is why spring calls tend to cluster on the first chilly mornings of fall and winter.

What Should You Do in the First Hour After a Spring Breaks?
Most of the damage we see after a spring failure happens after the spring breaks, not during it. Follow these steps in order:
- Stop pressing the opener button. Every attempt forces the motor to lift weight it was never designed for. Openers with plastic drive gears can strip them within a few tries.
- Unplug the opener. This keeps anyone else in the house, or a car remote, from triggering the door while it is unsupported.
- Leave the door in the position it is in. If the door is closed, leave it closed. If it is partly or fully open, do not pull the red emergency release cord. That cord disconnects the door from the opener, and with no spring holding it, the door can drop straight down.
- Keep people, pets, and vehicles out of the door’s path. Treat the opening as a no-walk zone until the door is secured.
- Do not try to lift it by hand. A door with a broken spring is heavy, uneven, and can slip out of your grip near the top or bottom of its travel.
- Look, but do not touch. Note whether you have springs on a bar above the door or springs along the side tracks, and whether the cables look slack. That information helps a technician bring the right parts.
- Call for repair. If a car is trapped inside and you need it out today, tell the dispatcher. Our 24/7 emergency garage door service is set up for exactly that situation.
Can You Open a Garage Door With a Broken Spring?
Technically, sometimes. Practically, it is a bad idea for most homeowners. With a single-spring torsion system, the broken spring means there is no counterbalance at all, and the door is a dead weight. With a two-spring system, one spring may still hold some of the load, which is why some doors can still be lifted a short distance, often crookedly.
The problem is not only the weight. When a door lifts unevenly, one side climbs faster than the other. That twists the sections, can pull rollers out of the track, and can unwind a cable from its drum. At that point you have a broken spring, an off-track door, and possibly a damaged panel, all from one attempt to get the car out.
If your car absolutely has to come out before a technician arrives, the safer move is to ask the dispatcher whether the technician can secure the door and release the car first. That is a common request and a quick one for someone with the right clamps and tools.
Why Shouldn’t You Replace a Garage Door Spring Yourself?
Torsion springs are wound by hand using steel winding bars inserted into a cone at the end of the spring. The person doing the work is holding back stored torque with each quarter turn. If a bar slips or the wrong tool is used, the bar spins with enough force to break bones. The set screws, the cones, and the center bearing plate all sit in that same zone of stored energy.
Extension springs carry their own risk. They stretch under load, and if one breaks without a safety cable running through it, pieces of the spring can fly across the garage.
There is also the matter of sizing. Springs are matched to the door’s weight, height, and drum size by wire gauge, inside diameter, and length. A spring that is a little too strong or too weak leaves the door out of balance, which shortens the life of the new spring and the opener. We cover the bigger picture in reasons not to handle your own garage door repairs.
What Happens During a Professional Spring Replacement?
A proper garage door spring replacement is more than swapping the broken coil. Here is what the visit should include:
- Securing the door. The technician clamps the door in place so it cannot move while tension is released and reapplied.
- Releasing the remaining tension. On a two-spring system, the unbroken spring still holds energy and has to be unwound safely.
- Measuring and matching. The new springs are sized to the actual door, not just copied from the broken one, since the broken spring may have been the wrong size to begin with.
- Replacing both springs on a two-spring door. Springs installed at the same time wear at the same rate. Replacing only the broken one leaves an old spring and a new spring working against each other.
- Inspecting the parts that took the shock. Cables, drums, bottom brackets, bearings, and rollers are checked. A spring failure often frays a cable or loosens a drum.
- Balancing and testing. The door should stay put when lifted halfway by hand and released. The opener’s force and travel settings are checked, along with the auto-reverse safety function.
Most residential spring replacements are completed in one visit. Our technicians work out of fully stocked service vehicles, which is why we can usually handle the spring and any related part, such as worn rollers, on the same trip.
Did the Broken Spring Damage Anything Else?
Often, yes, and it is worth asking about before the technician leaves. The parts most likely to need attention after a spring failure are:
The opener. If the opener ran several times against a dead-weight door, the drive gear or trolley may be stripped. A door that now opens but makes a grinding sound from the motor unit is a common sign. Our team handles garage door opener repair on the same visit when parts are on the truck.
The cables. A cable that jumped its drum or took a sudden shock load can kink or fray, and a kinked cable is a weak cable.
The top section. Openers pull from the top section of the door. Repeated attempts to lift an unsupported door can bend that section or crack the area where the opener arm attaches.
The tracks. Uneven lifting can bend a track or pull a track bracket loose from the wall.
How Does California’s Climate Affect Garage Door Springs?
Spring life varies by where you live, and the differences across our service area are noticeable.
Heat cycling in the Central Valley. In Sacramento, Fresno, Modesto, and Bakersfield, closed garages routinely get very hot on summer afternoons and cool down overnight. That daily swing, combined with heavy use during school and work months, tends to wear springs and lubricants faster.
Salt air and fog on the coast. Homes in San Francisco, Pacifica, Daly City, and Half Moon Bay see moisture and salt settle on spring coils. Rust between the coils adds friction, and pitted wire fails at the pit.
Cold mornings in the foothills. In Grass Valley, Placerville, Auburn, and Redding, the first cold snaps of fall and winter bring a predictable run of broken springs, because already-fatigued steel finally gives out under a cold start.
Wherever you are, a yearly inspection and lubrication through a residential garage door maintenance visit is the simplest way to stretch spring life and spot fatigue early.
The Bottom Line
A broken garage door spring turns a balanced door into dead weight. The bang is the spring failing, and everything that happens afterward depends on what you do next.
Stop using the opener, unplug it, leave the door in place, and keep everyone clear. Do not pull the emergency release on a door that is open, and do not try to wind or replace a torsion spring yourself.
Have both springs replaced on a two-spring door, ask that the cables, drums, and opener be checked, and make sure the door is balanced before the technician leaves. Done that way, a broken spring is a single repair rather than the start of several.
Frequently Asked Questions About a Broken Garage Door Spring
Can I manually lift my garage door if the spring is broken?
It is not recommended. Without spring support, you are lifting the full weight of the door, which can be several hundred pounds on a double-car door, and it can slip or drop unexpectedly. Lifting a door with one broken spring can also make it rise unevenly and come off its tracks.
Is it okay to open a garage with one spring broken?
No. Even if one spring on a two-spring door still works, it is now carrying the load meant for two, and the door will lift unevenly. Running the opener in that condition strains the motor and cables and can damage the door sections. Leave the door in place until the springs are replaced.
Can I fix my garage door spring myself?
Replacing a torsion spring involves releasing and reapplying a large amount of stored tension with winding bars, and a slip can cause serious injury. Springs also have to be sized to the door’s weight and height to keep the door balanced. This is a job for a trained technician with the correct tools and parts.
When a garage door spring breaks, should you replace both?
Yes, on a door with two springs. Both springs have been through the same number of cycles, so the one that has not broken yet is usually close behind. Replacing them together keeps the door balanced and saves a second service call a few months later.
What does it sound like when a garage door spring breaks?
Most people describe a loud bang, similar to a firecracker or gunshot, coming from the garage. It often happens when the door is closed and not moving, because that is when a torsion spring is under the most tension. Afterward, you will usually see a visible gap in one of the coils above the door.
Is it common for garage door springs to break?
Yes. Springs are designed to last a set number of open and close cycles, and every spring eventually reaches that limit. Heavy daily use, rust, an unbalanced door, or springs that were undersized for the door all shorten that timeline. A spring failure is one of the most common garage door repairs.
