In our years serving Sunnyvale, we've seen this problem again and again: a homeowner wakes up, hits the garage door opener button, and hears a loud BANG. The door doesn't budge. That sound is almost always a snapped spring, and it means your garage door is now a 300 to 400 pound weight that no opener can lift. The good news? It's fixable, but speed matters because a broken spring is a safety hazard that affects your whole household.
Your garage door has either one or two springs (depending on your setup) that counterbalance the weight of the door. These are torsion springs wound tighter than guitar strings, storing enormous tension. When one fails, the other has to carry the full load, which usually means it fails within days or weeks.
You'll notice it immediately. The door either won't open at all, or it opens partway and gets stuck. Some people describe hearing a gunshot sound from the garage. That's the spring giving way under pressure it can no longer handle.
Torsion springs typically last 7 to 9 years with normal use. If your door is older than that and you've never had spring service, a failure is coming. Humidity, temperature swings, and constant cycling all wear them down faster than most homeowners expect.
A broken spring doesn't just inconvenience you. It's a genuine safety issue. The opener motor will strain trying to lift a door that's no longer balanced. If you manually try to lift the door, the full weight drops on your hands or head. People get seriously injured this way.
Also, a stuck door blocks your car. If you need to leave for work, a hospital visit, or an emergency, you're trapped. That's why we offer emergency garage door service in Sunnyvale to handle calls seven days a week.
Never attempt to replace torsion springs yourself. The tension stored in them can cause severe injury or death if released improperly. This is a job for trained technicians with the right tools and insurance.

Some garage doors use extension springs (one on each side of the door above the tracks) instead of a central torsion spring. Extension springs are slightly less dangerous to work around, but they're just as critical to safe operation. Both types eventually fail. The main difference is cost and replacement time.
If you're not sure which type you have, look in your garage. Do you see a spring wound around a rod above the center of the door? That's torsion. Do you see two springs running horizontally along the track? Those are extension springs. Either way, when one snaps, you need professional help.
When you call Garage Door Sunnyvale for a snapped spring, we'll ask a few quick questions: How old is the door? Do you hear any other noises? Have both springs failed, or just one? Then we'll schedule you for same-day service if you call early enough.
During the visit, we inspect the remaining spring (if you have two) and the door hardware. A snapped spring often means the other one is close behind, so we usually recommend replacing both at the same time. We'll give you an honest estimate before we start any work.

Can I use my garage door if one spring is snapped? No. Using the door risks damage to the opener and tracks, plus serious injury. The remaining spring (if you have two) will fail quickly under extra load. Wait for professional repair.
How long do garage door springs last? Quality torsion and extension springs last 7 to 9 years under normal residential use. Factors like climate, frequency of use, and maintenance affect lifespan. Older doors should be inspected annually.
Is a snapped spring covered by warranty? Most springs come with a 5 to 10 year manufacturer warranty, but normal wear and tear usually aren't covered. We'll check your specific spring when we arrive and advise on warranty options.
