Most people don't think about their garage door until something goes wrong. Then a spring fails, the door gets stuck halfway up, and suddenly you're locked out of your garage on a Tuesday morning. A snapped torsion spring isn't just inconvenient.it's a safety hazard and a repair that demands professional help fast. Here's what you need to know right now.
Garage door springs wear out. That's not a flaw; it's physics. A typical torsion spring handles roughly 10,000 to 20,000 open-and-close cycles before it reaches the end of its life. Most homeowners get 7 to 9 years of use before replacement becomes necessary.
Several factors speed up that timeline. Rust accelerates wear, especially in the Bay Area where coastal moisture settles on metal. Lack of lubrication forces the spring to work harder. Sudden temperature swings (San Francisco sees plenty of those) cause metal to expand and contract, weakening the coil. And if you've been forcing the door open when it's stuck, you've already damaged the spring mechanism.
The bottom line: when a spring snaps, it's usually old. Sometimes very old.
Here's what you're experiencing right now. The door is either stuck in the open position or won't budge at all. You might hear a loud bang or crack when it happens. The door feels heavier than normal if you try to lift it manually (don't keep trying.you can hurt yourself).
That heaviness is the real danger. Without a working spring, the full weight of the door rests on the opener motor and the cable. The opener wasn't designed to hold that load. Forcing it will burn out the motor and snap cables. That turns a spring repair into a much larger, costlier job.

Springs operate under extreme tension. A torsion spring can launch a wrench across the garage or cause serious injury if mishandled. Extension springs have a different failure mode but pose the same risk. Even experienced homeowners have lost fingers or eyes attempting spring repairs.
A professional technician has the right tools, knows how to safely release tension, and can replace the spring without damaging the cable, pulley, or door itself. This is one repair where the cost of hiring help is far cheaper than a hospital visit or a ruined door.

Spring replacement costs depend on the type of spring, the door weight, and local labor rates. A single torsion spring replacement typically runs between $150 and $300 for the part and service. If both springs need replacement (and they often do, since they age together), expect to pay more.

When a spring snaps, you want it fixed today. Most emergency repair calls in San Francisco can be scheduled the same day if you contact a local service before mid-afternoon. Delays happen on weekends and holidays, so act fast if it's a Friday.
Call 415-915-8187 and describe what happened. The technician will ask about your door type, age, and whether both springs are still intact. They'll give you a time window and cost estimate. Many calls result in same-day appointments.
If you're unsure whether the problem is the spring or something else, our team at Garage Door San Francisco can troubleshoot over the phone before you commit to a service call.
Once one spring fails, the other is usually close behind. They age together. Replacing both springs at the same time costs less than waiting for the second one to snap a month later.
Regular maintenance catches worn springs before they break. A yearly tune-up includes lubrication, tension checks, and safety testing. That small investment prevents emergency calls and extends the life of your entire door system. Learn more about garage door maintenance that prevents emergencies.

How long does a garage door spring replacement take? Most spring replacements finish in 1 to 2 hours, depending on whether one or both springs need work and the door's weight. Same-day appointments are common in San Francisco if you call early in the day.
Can I manually open my garage door after a spring snaps? You can lift it, but don't. The full door weight presses down without spring support. Forcing it risks injury and damages the opener motor and cables. Wait for professional help.
What's the difference between torsion and extension springs? Torsion springs wind tightly above the door and unwind to lift it. Extension springs run horizontally along the cables and stretch to provide lift. Both fail over time; both require professional replacement for safety.
Do I need to replace both springs if only one breaks? Usually yes. Springs age together and reach failure around the same time. Replacing both at once prevents a second emergency call within weeks and costs less overall than two separate visits.
How can I prevent spring failure? Annual maintenance helps. Lubrication reduces wear, and a technician can spot tension loss early. Avoid forcing the door open when it's stuck, and keep the area around springs clean and dry to prevent rust.
