Snapped Garage Door Springs in Los Altos: Why DIY Is Dangerous
2026-08-08 7 min read
A snapped garage door spring means your door is stuck, heavy, and unsafe to operate. Don't attempt a fix yourself. Call a professional for same-day service in Los Altos instead.
I've seen too many DIY garage door spring injuries to stay quiet about this. Homeowners underestimate the danger because springs look like simple metal coils. They're not. A torsion spring under tension stores enough energy to cause serious lacerations or broken bones. Even worse, people try to "work around" a broken spring and end up crushing fingers or worse when the door drops unexpectedly.
This post walks you through what happens when a spring fails, why professionals handle this work, and how to get help fast in Los Altos.
How Garage Door Springs Fail
Garage door springs are engineered to lift a door weighing 300 to 500 pounds repeatedly. A typical torsion spring above your door (the most common type in residential homes) completes roughly 10,000 to 15,000 cycles before it wears out. That's about 7 to 9 years of regular use.
Springs don't always fail gracefully. Metal fatigues. Rust builds up in the coils. Temperature swings in the Bay Area (even mild ones in Los Altos) cause expansion and contraction. Eventually, the coil snaps.
The moment it fails, your door becomes a liability. Without the spring's counterbalance, the opener motor works overtime trying to lift dead weight. The door may jerk violently or drop suddenly. If your car is underneath? Or a child's hand on the button? The results are catastrophic.
Why Extension Springs Are Also Dangerous
Some older homes in Los Altos use extension springs instead of torsion springs. These run along the sides of the door tracks and stretch to help lift the door. When an extension spring snaps, the broken end whips across the garage at high speed with enough force to shatter windows or crack skulls.
That's why modern extension springs have safety cables threaded through them. The cable catches the spring if it breaks, preventing the violent snap. But safety cables only work if they're in place. If someone removed them for repairs years ago and forgot to reinstall them, your garage becomes a danger zone.
You can't visually inspect a snapped spring safely. Don't try. Call a professional who has the right tools, experience, and liability insurance.
What to Do Right Now
Stop using your garage door immediately. Don't press the opener button. Don't try to manually lift the door. Don't tinker with the springs, cables, or pulleys.
If your door is stuck open, park outside until repairs are complete. If it's stuck closed and you need access to your garage, call for help rather than forcing the door.

Spring Replacement: What Happens Next
When you call us for a snapped spring, here's what to expect. Our technician arrives with replacement springs already on the truck. We disconnect power to the opener, secure the door in the fully closed position, and relieve tension on the remaining hardware.
Then we remove the old spring and install a new one rated for your door's weight and cycle life. We test the door multiple times to confirm smooth, balanced operation. The whole job typically takes 1 to 2 hours.
We also inspect your cables, rollers, and tracks while we're at it. A snapped spring often signals that maintenance was skipped. Read more about what you should be doing regularly in our guide to garage door maintenance in Los Altos.

Prevention: The Real Win
You can't prevent springs from aging. But you can extend their life dramatically through annual maintenance and lubrication. Springs last longer when they're not fighting rust, debris, or dry friction.
Schedule annual service before a spring fails. A tech will lubricate the springs, check for early wear signs, and catch problems while you still have options. It costs less than an emergency call.
If your door is over 7 years old and you've never had the springs serviced, have them inspected now. A preventive inspection costs far less than an emergency replacement and gives you control over timing instead of scrambling when a spring snaps at 6 p.m. on a Saturday.

Frequently Asked Questions
How long does a snapped spring repair take? Most spring replacements finish in 1 to 2 hours, depending on spring type and door complexity. We aim for same-day service across Los Altos and surrounding areas.
Can I open my garage door if one spring is snapped? No. Operating the door with a broken spring risks injury and damage to the opener motor. Keep the door closed until the spring is replaced.
What's the difference between torsion and extension springs? Torsion springs sit above the door and twist to lift it. Extension springs run along tracks and stretch. Both are dangerous when they fail. Torsion is more common in newer homes and safer overall.
How often should springs be serviced? We recommend annual inspection and lubrication, especially in Los Altos where temperature swings cause expansion. This extends spring life by 1 to 2 years.
Do I need to replace both springs even if only one snapped? If both springs are the same age, we recommend replacing both. They wear together, and replacing only one creates imbalance that stresses your door and opener.
