A snapped garage door spring means your door is stuck and unsafe to operate. Stop using the opener immediately, keep people and pets away, and call a technician today. Most springs fail without warning after 7 to 9 years of use, and a broken one cannot support the door's weight on its own.
Last Tuesday, a homeowner in Sebastopol called in a panic. She'd heard a loud bang from the garage that morning, and when she tried to open the door for work, nothing happened. The opener hummed but the door didn't budge. She'd found the problem herself: a torsion spring above the door had snapped clean in half.
That's the call I get three times a week, and it never gets old because it's genuinely dangerous.
Garage door springs are under enormous tension. A torsion spring on a standard residential door carries roughly 200 pounds of force per spring. Over thousands of open and close cycles, metal fatigues. Small cracks form inside the coil. Then one morning, it gives up.
The typical lifespan is 7 to 9 years for a residential home that opens the door 3 to 5 times per day. If you've had your door longer than that, a snapped spring isn't a question of if, but when.
Extension springs (the type that run along the sides of the door) fail the same way, though you might see them hang loose before they snap completely. Torsion springs are trickier. They're mounted high above your head, and when they fail, there's no gradual warning.
The door becomes deadweight. Without the spring's counterbalance, the opener cannot lift it. Trying to force it with the remote only stresses the opener motor and can cause secondary damage that costs more to fix.
I've seen people attempt to manually lift a door with a snapped spring. Don't. The door can fall suddenly, and the force is unpredictable. Fingers, hands, and heads have been seriously injured.
If you have a snapped spring, treat it as an emergency. Keep the door closed and stationary until a professional arrives.

Once a spring snaps, repair isn't an option. Springs cannot be welded safely or spliced. The entire spring must be replaced.
If you have two torsion springs (common in two-car garages), I recommend replacing both at the same time, even if only one has failed. The second one is likely near the end of its life. Replacing both costs more upfront but saves you from another emergency call in six months. This is covered in detail in our post on when to repair versus replace garage door springs.
The cost varies based on spring type and door weight. A standard torsion spring replacement ranges from $200 to $400 per spring, plus labor. An extension spring is typically $150 to $250 per spring. For an accurate estimate for your specific door, schedule a free quote with us.
First, stop. Do not attempt to open or close the door manually or with the opener.
Second, call a technician. In Sebastopol, we offer same-day service for snapped springs. The longer the door sits immobile, the more frustrated you become, and the more likely you'll try something unsafe.
When you call, have this information ready: the age of your door if you know it, whether you have one or two springs, and when you heard the snap. This helps us confirm we have the right parts on the truck.
If the door is blocking your vehicles, some people ask if they can prop it open with a ladder or brace it. I advise against this. A partially open door with a failed spring is unstable and can shift unexpectedly.
Springs last 7 to 9 years. If yours are older, schedule an inspection. Many homeowners discover a snapped spring only after it fails, but a technician can spot a weak spring during routine maintenance and replace it before disaster strikes.

Can I open my garage door if the spring is snapped? No. The door is deadweight without the spring's counterbalance. The opener cannot lift it safely, and attempting to do so risks damage to the motor and serious injury to anyone nearby.
How long does it take to replace a snapped spring? A typical replacement takes 1 to 2 hours, depending on whether you have one or two springs and how accessible they are. We often complete same-day service in Sebastopol.
Why do springs snap without warning? Springs cycle thousands of times over 7 to 9 years. Metal fatigues internally, creating small cracks that eventually fail suddenly. There's rarely a gradual warning sign before a torsion spring breaks.
Is it okay to replace just one spring if I have two? Technically yes, but both springs are usually near the same age. Replacing both at once costs more upfront but prevents another emergency in months. We recommend this approach for most customers.
How much does a spring replacement cost? Torsion springs typically run $200 to $400 per spring plus labor. Extension springs cost $150 to $250. Exact pricing depends on your door weight and spring type. Call (510) 319-0841 for a free estimate.
