A customer called last Tuesday morning. His garage door wouldn't budge. After 12 years, one of his torsion springs had snapped overnight, and he needed it fixed before leaving for work. This scenario plays out regularly across San Francisco. Springs fail without warning, they're critical to how your door operates, and replacing them costs between $200 and $400 depending on the type and condition of your system.
Your garage door weighs between 300 and 400 pounds. Without springs, your opener motor would burn out in weeks trying to lift that load alone. Springs counterbalance the weight, making the door feel almost weightless when you open or close it manually. There are two main types: torsion springs (mounted above the door on a horizontal rod) and extension springs (running along the sides). Torsion springs are more durable and safer, lasting 7 to 9 years with regular use. Extension springs typically last 5 to 7 years.
When one snaps, the entire system becomes unbalanced. Your opener works harder. The door can become a safety hazard. You might hear a loud bang, similar to a gunshot, when a spring fails. This is normal and terrifying in equal measure.
Listen for noise during operation. A creaking, squeaking, or grinding sound suggests springs are losing tension. Watch how your door moves. If it rises unevenly, jerks to one side, or falls faster than it should, springs are likely failing. You may also notice the door feeling heavier when you try to open it manually (disconnect the opener first and lift gently). Never force a stuck door. Call a professional instead.
We wrote a detailed guide on warning signs your garage door needs professional repair that covers these symptoms in depth.
Torsion springs sit on a rod above your door. They twist as the door opens and closes, storing and releasing energy smoothly. Extension springs hang on pulleys beside the door tracks. They stretch and contract like rubber bands. Torsion springs cost more to replace but last longer and operate more quietly. Extension springs are cheaper upfront but need replacement sooner. Both require professional installation. This is not a DIY job. Spring tension can cause serious injury.

A single torsion spring replacement runs $300 to $400 in San Francisco. Extension springs cost $150 to $250 each. If both springs are original, both are likely worn and should be replaced together, even if only one has snapped. This prevents the second from failing weeks later. Our emergency garage door service guide breaks down pricing and response times in detail.
Most jobs take 1 to 2 hours. We can often schedule same-day appointments for snapped springs. The Daly City and Oakland areas also experience similar wear patterns due to humidity and temperature swings, so spring failure is common throughout the Bay Area.
Parts alone cost $50 to $150. Labor makes up the bulk of the bill. When you call for an estimate, we ask about your door's age and whether both springs are original. This helps us predict whether a second failure is imminent and prevent a second emergency call.
Springs don't fail because of poor maintenance. They wear out through normal use. Still, regular inspection helps catch problems early. During seasonal maintenance visits, we check spring tension and listen for stress sounds. Lubricating springs annually with garage door lubricant keeps them operating smoothly, though it won't extend their lifespan significantly.
If your door is 10 years old and you're unsure about spring condition, schedule a free quote so we can assess what you're working with. A small investment in inspection now beats an emergency call at midnight.
Springs are under extreme tension. A mistake during installation can cause the spring to unwind violently, causing injury or property damage. We use calibrated tools to measure tension precisely. We verify both springs match in strength before installation. We test the door's balance multiple times.
Your opener also needs adjustment after spring replacement. If the force settings aren't recalibrated, the door won't close properly or the opener will work too hard. This is why choosing experienced technicians matters more than price.

How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs last 5 to 7 years. Lifespan depends on usage frequency and climate. Springs in humid areas like San Francisco may wear slightly faster due to corrosion.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Professional installation with proper tools and safety precautions is essential. Always hire a licensed technician.
What does a snapped spring sound like? Most people describe it as a loud bang or crack, similar to a gunshot. It happens suddenly and indicates immediate professional service is needed. The door will be difficult or impossible to open safely afterward.
Why do both springs need replacement if only one broke? Springs wear together. If one is original and has failed, the other is equally worn and will fail soon. Replacing both prevents a second emergency and reduces total labor costs.
How much does spring replacement cost in San Francisco? Single torsion spring replacement ranges from $300 to $400. Extension springs cost $150 to $250 each. Many jobs require both springs replaced together, increasing total cost but ensuring long-term reliability.
