The spring is what makes a hundred-plus pound door feel light. With it gone, the opener is lifting the whole thing and paying for it with every attempt.
A broken garage door spring leaves the full weight of the door on the opener and on anyone lifting it by hand, which is why the first instruction is to stop rather than to troubleshoot. Replacement runs about $300 to $540 installed for torsion springs, and the parts themselves are only $80 to $120 of that.
Confirm it in ten seconds
How do you know a spring has broken?
Look at the spring above the door. A failed torsion spring shows a visible gap of two or three inches in what should be a continuous coil. Combined with a door that lifts a few inches and stops, that is conclusive.
Many people also remember a loud bang from the garage earlier that day or in the night. A torsion spring failing sounds like a gunshot, and it is routinely mistaken for something falling off a shelf.
What to do in the next five minutes
Confirm, stop, secure, call
01
Look above the door
A torsion spring that has failed shows a visible gap of two or three inches in the coil. It is unmistakable once you know to look for it.
02
Stop using the opener
The opener is now lifting the full weight of the door. Every attempt strips gear teeth, and it can pull cables off their drums.
03
Check how the door sits
A door that lifts a few inches, rises crooked, or slams the last foot down is telling you the counterbalance has gone.
04
Leave it closed and call someone
A closed door is a safe door. Use a side door for access and get a technician out rather than working around it for a week.
Stop using the opener
This is the instruction with the clearest financial consequence, and it is the one people ignore for a week.
The opener is sized to move a counterbalanced door, not to lift it. With the spring gone it is hauling the entire weight through a plastic gear set that was never designed for the load. Gear teeth strip, motors burn out, and cables can pull off their drums under the uneven pull.
What a week of trying actually costs
A spring replacement is a bounded job with a known price. A spring plus a stripped opener gear set plus cables off their drums is two or three times that, and every one of those additions is caused by continuing to press the button. Stopping now is the cheapest decision available.
Can you use the door with one spring broken?
The People Also Ask block asks this twice, and the ranking pages answer it inconsistently. The honest answer is no in both configurations.
Two spring door, one broken: the survivor is carrying double the load it was sized for, and it is the same age.
Single spring door: there is no counterbalance at all and the door is at its full weight.
Either case: the door can drop faster than expected on the way down.
Either case: the opener is being damaged with every cycle.
Why a broken garage door spring happens when it does
Springs are consumables with a rated life, and that reframes the failure as maintenance rather than bad luck.
They are rated in cycles, where one cycle is one open and one close, and they fatigue steadily through that life. A household using the garage as its main entrance burns through cycles several times faster than one that uses it twice a week.
Cold snaps are the classic trigger. The cold does not break a healthy spring, it finishes one that was already at the end of its cycle life.
What a car trapped inside actually costs you
This is the practical problem, and it deserves a straight answer rather than a cheerful one.
With a broken spring, lifting the door by hand means lifting its full weight with no assistance. On a single door that is difficult. On an insulated double door it is a genuine two person lift, and a slip means the door coming down.
Use a side door or the internal house door if one exists, and leave the garage door closed.
Never prop a raised door with a ladder, a broom or a jack. Anything that can shift will.
Do not drive out under a door somebody is holding up.
If you must lift it, two people, evenly, and lower it fully rather than leaving it raised.
Search results for this problem include a steady stream of improvised workarounds, and they are worth naming so you can recognise them.
Clamping the track, propping the door, using vice grips as a stop, or winding a spring with a screwdriver all appear regularly. Each of them leaves stored energy in an uncontrolled state, and each of them puts a person directly under a load with no restraint.
The genuine temporary fix is leaving the door closed until a technician attends. A closed garage door is secure, weatherproof and safe, and it costs nothing to leave it that way overnight.
What gets replaced, and what else to check
Knowing the scope makes the quote readable.
Both springs get replaced as standard, because both have the same cycle history. Cables and drums are inspected for damage from the failure and from any continued opener use. The door is then rebalanced and the opener force settings reset, because those settings assume a properly counterbalanced door.
Do not operate the opener with a broken spring. The motor is not built to lift the door alone and you will replace the opener as well.

The third row is the one that explains the whole pricing structure. Parts are a small fraction of the installed cost, and the rest is the winding, which is exactly the part that carries the risk.

“Garage Door Spring Snapped in Half! Seeking Advice”
SourceThread title, r/HomeImprovement. The replies converge on two points within the first few comments: stop using the opener, and this is not the repair to learn DIY on.
“How do I fix a broken garage door spring after hours?”
SourceThread title from a community Q and A on this SERP. The answer that keeps recurring is that the door is safe closed and the repair can wait for daylight.
“Even installer and DIY sources on this SERP flag torsion spring work as high risk”
SourceObserved across the ranking pages for spring repair, where the organic results are dominated by DIY videos and the written sources still recommend professional replacement.

The after-hours thread is the useful one. A broken spring feels like an emergency and is mostly not one, provided the door is left closed and nobody tries to work around it.

Straight answers
Frequently asked questions
The questions homeowners actually search for on this problem, answered in plain language.
Look above the door. A torsion spring that has failed shows a visible gap of a few inches in the coil. The door will lift a few inches and stop, or rise crooked, and the opener will strain audibly. Many people also recall a loud bang shortly beforehand.
Can I still use my garage door if the spring is broken?
No. On a two spring door the remaining spring is carrying double the load it was designed for, and on a single spring door there is no counterbalance at all. Running the opener anyway strips gears, burns out motors and can damage cables and drums.
How do I open a garage door if the spring is broken?
Carefully, and preferably not at all. Pull the emergency release only with the door fully closed, and understand that lifting by hand means lifting the entire weight of the door. On a double door that is a two person job at minimum, and often not worth attempting.
Is it common for a garage door spring to break?
Yes. Springs are rated in cycles and they fatigue with use, so failure is expected rather than exceptional. Households that use the garage as the main entrance consume cycles quickly, and cold weather often triggers a spring that was already near the end.
Should I replace one spring or both?
Both. They have done the same number of cycles, so the survivor is typically close behind the one that failed. Replacing a single spring means paying the labour twice within a short period, which is why fitting a pair is standard practice.
What does it cost to fix a broken garage door spring?
Torsion spring replacement runs about $300 to $540 installed with an average near $420, and extension springs about $300 to $400. The parts themselves are about $80 to $120 for torsion or $20 to $60 for extension, with the rest being the winding and balancing labour.
What a failed torsion spring looks like
Winding bars, and why they matter
The labor is the part worth paying for. A wound torsion spring stores enough energy to break bones if a winding bar slips.
