5 Warning Signs Your Garage Door Spring Is About to Fail in Los Gatos
2026-03-24 6 min read
There's a particular kind of bad morning that garage door technicians hear about constantly: you walk into the garage, hit the opener button, and the door lurches a few inches and stops. Or it goes up crooked. Or there's a loud bang from earlier that you assumed was something outside. In almost every one of those cases, a spring has failed.
Garage door springs are the hardest-working component in the system. They carry the full weight of the door. often 150 to 200 pounds. through thousands of open-and-close cycles. And in Los Gatos, where homeowners use their garages year-round as the primary entry point into their homes, those cycles add up fast.
The good news is that springs rarely fail without warning. Here's what to watch for.
How Garage Door Springs Work (and Why They Fail)
Most modern garage doors in Los Gatos use torsion springs. horizontal coils mounted above the door on a metal shaft. When the door closes, the springs wind up and store energy. When the opener runs, that stored energy does most of the lifting. A standard spring is rated for roughly 10,000 cycles, which translates to about 7,10 years of normal use if the garage is opened two to four times a day.
Older homes. including many of the mid-century ranch houses in Belwood and around Blossom Manor. may still have extension springs, which run along the sides of the door and stretch and contract with each cycle. These tend to wear differently and can be more dangerous when they snap because the coil can travel if not properly contained with a safety cable.

5 Signs Your Springs Are Wearing Out
1. The Door Feels Unusually Heavy
Disconnect your opener by pulling the red emergency release cord, then try lifting the door manually from the bottom. A properly balanced door should lift with moderate resistance and stay open at about waist height without drifting. If it feels like you're lifting dead weight, or if it won't stay up, the springs have lost tension. Continuing to use the opener in this condition puts serious strain on the motor.
2. The Door Opens Unevenly or Crooked
If one side of the door rises faster than the other, it often means one spring has failed or weakened while the other is still functional. You'll notice the door looks tilted or hear the cables going slack on one side. Don't force it. a crooked door can jump the track and cause real damage.
3. You Hear a Loud Bang from the Garage
A snapping torsion spring sounds like a firecracker or a small gunshot. Many homeowners hear it at night and assume it's something outside. If you hear a bang and the door behaves oddly the next morning, that's what happened. At this point the door is essentially non-functional and needs immediate attention. contact us for same-day service if you're in this situation.
4. There's a Visible Gap in the Spring Coil
Look at the torsion spring above your door. A healthy spring is a tight, evenly wound coil. A broken one will have a gap of roughly two inches or more where it snapped. This is the most definitive sign. if you see a gap, the spring is done. Don't attempt to use the door.
5. Rust or Visible Corrosion on the Coils
This is the early-warning sign most homeowners miss. A rusty spring is more brittle and prone to sudden failure. Given that Los Gatos winters bring sustained humidity. January averages around 80% relative humidity. springs in garages with poor sealing are exposed to more moisture than you might expect. Surface rust that covers a significant portion of the coil means failure is coming sooner rather than later. A technician can treat or replace the spring before it becomes an emergency.
What Happens If You Ignore It
A failing spring puts the entire load of the door on the opener motor, which isn't designed to carry it. Motors burn out. Cables fray and snap. In worst-case scenarios, a broken spring with no safety cable can send metal flying across the garage. It's one of the few garage door issues where waiting genuinely creates more risk and more cost.
Homeowners in Saratoga and Campbell. where homes tend to be similar in age and construction to many Los Gatos neighborhoods. see the same issues, and the same pattern: a small problem that could have been caught in a tune-up turns into a multi-component repair.
Should You Replace Both Springs at Once?
This is one of the most common questions we get. The honest answer: yes, if one spring has failed and you have two, replace both. Springs on the same door are installed at the same time and put through the same number of cycles. If one has failed, the other is likely close behind. Replacing both at once saves a second service call and keeps the door balanced.
High-cycle springs. rated for 25,000 to 50,000 cycles. cost more upfront but last significantly longer. For a busy family household in Los Gatos where the garage is the main entrance, the upgrade often makes practical sense.

Frequently Asked Questions
Q: Is it safe to open my garage door with a broken spring? A: No. With a broken spring, the opener is carrying the full weight of the door, which it isn't designed to do. The door may open partially and then drop suddenly, which is a serious safety hazard. Use the manual release and keep the door closed until the spring is replaced.
Q: How long does a garage door spring replacement take? A: For a professional technician, a standard torsion spring replacement typically takes 45 minutes to an hour. Replacing both springs on a two-spring system adds a little time but not much. Same-day service is usually available. reach out here to schedule.
Q: Can I replace a garage door spring myself? A: Technically yes, but it's one of the more dangerous DIY garage jobs. Torsion springs are under extreme tension, and an improper installation can result in the spring snapping during winding. which causes serious injury. Most professional technicians strongly advise against it. The cost of a professional replacement is modest compared to the risk.
