Snapped Garage Door Spring in Cupertino? Here's What to Do Now
2026-08-02 7 min read
A snapped garage door spring is one of the most common emergencies we handle in Cupertino. The spring breaks, your door won't open or close, and suddenly you're locked out of your garage when you need it most. The good news: this is fixable, usually the same day, and we can walk you through what happens next.
Why Springs Break Without Warning
Garage door springs are under tremendous tension. A typical torsion spring on a standard residential door supports roughly 200 to 400 pounds of force. Over time, metal fatigues. Springs last 7 to 9 years on average, depending on how often you use your door. If yours has been around longer, a snapped spring isn't a surprise.
Most breaks happen because the spring has simply reached the end of its service life. You'll hear a loud bang or crack from the garage, like a gunshot. Don't ignore that sound. Once one spring breaks, the other side typically follows within weeks or months because both have endured the same wear and tear.
Cold weather can accelerate failure too. Winter mornings in the Bay Area get chilly, and metal contracts in the cold. This added stress can trigger a break that was already coming.
What You'll Notice When a Spring Snaps
Your garage door opener won't lift the door. The door feels heavier than normal, or it won't move at all. Some people try the remote multiple times, hoping it was just a glitch. It wasn't.
Do not force the door open manually or try to operate the opener. A broken spring means all the weight falls on the opener motor, which can burn out in seconds. You could also hurt yourself. The best move is to call for help and wait.
If you need to get in or out urgently, use a side door or another entrance. Your vehicle can wait a few hours for a professional to arrive.
Extension vs. Torsion: Which One Broke?
Most homes in Cupertino have torsion springs mounted horizontally above the door. These are the heavy-duty workhorses. Some older homes have extension springs that run along the sides of the door. Both can snap, though torsion springs are more common in modern installations.

The Repair Process and Cost
Once we arrive, we inspect both springs. Even if only one snapped, we almost always recommend replacing both at the same time. Replacing just one means the other will fail soon after, and you'll pay for another service call.
A full spring replacement takes 1 to 2 hours. We remove the broken spring, install new hardware, and balance the door so it opens and closes smoothly. The cost depends on your spring type and door weight, but you can expect a free estimate when you call.

DIY Is Not an Option Here
We get calls from homeowners who looked up spring replacement on YouTube. It's understandable. But springs are genuinely dangerous. The tension stored in a compressed spring can cause serious injury or death if it releases unexpectedly. This is not a weekend project.
Our technicians have the right tools, safety cables, and years of experience. We do this safely and efficiently. It's worth the cost to avoid a trip to the hospital.
