After 15 years turning wrenches on garage doors across the Peninsula, I can tell you one thing for certain: most homeowners don't know what's actually holding their door up. Let me cut through the confusion about garage door springs. The short answer is you've got either a torsion spring mounted horizontally above the door, or extension springs running along the sides. Both do the same job. Both fail. And when they do, your door becomes a 400-pound paperweight. Understanding which type you have, and why it matters, can save you time, money, and a nasty surprise on a Tuesday morning.
Torsion springs work by twisting. They're mounted on a metal rod centered above your garage door opening. When you open the door, the spring unwinds, releasing stored energy that helps lift the weight. Think of it like a clock spring that's been wound tight. Extension springs do the opposite. They stretch and contract. Mounted along each side of the door frame, they expand as the door goes down and compress as it rises. Both carry the load, but the mechanics are completely different. See our guide on garage door springs in menlo park: why replacement costs less than you fear.
Here's what matters: torsion springs are safer and more durable. They last 7 to 9 years under normal use. Extension springs? Usually 5 to 7 years. Torsion springs also cost more upfront but rarely need adjustment. Extension springs require periodic maintenance and safety cables to catch them if they snap. If you have an older home in Menlo Park, you might still have extension springs. Newer installations almost always use torsion.
Springs fail for one reason: metal fatigue. Every time your door opens or closes, the spring cycles. A typical spring handles 10,000 to 15,000 cycles before it gives up. Do the math: open and close twice daily, that's roughly 7 to 9 years. Weather accelerates failure. Here in the Bay Area, we don't deal with harsh winters, but humidity and temperature swings still take their toll on metal.

A snapped spring feels dramatic. Your door won't open, or it opens but slams shut halfway. You'll hear a loud bang or crack. That's the spring finally letting go. Don't try to force it. A broken spring can't support the door's weight, and you risk damaging the opener or worse, getting hurt. This is when you need same-day service.
You might also notice your door opening slower than usual or not staying up on its own. These are early warning signs. Our team offers a garage door tune-up in Menlo Park that catches these issues before they become emergencies. Catching a weak spring early costs far less than dealing with a complete failure.
