Garage Door Spring Replacement in Los Gatos: What You Need to Know Before Yours Breaks
2026-04-11 7 min read
If you've ever heard a sudden, loud bang from your garage and walked out to find the door won't budge, there's a good chance a spring just gave out. It's one of the most common calls we get from homeowners across Los Gatos. and it's also one of the most misunderstood repairs on the entire door system.
Before you reach for the ladder or start watching YouTube tutorials, read this first. Spring replacement is genuinely dangerous, and there are things specific to Los Gatos homes that make this repair worth understanding in detail.
Why Springs Fail. And Why Los Gatos Homes See It Often
Garage door springs don't last forever. Most torsion springs are rated for 10,000 to 20,000 cycles. roughly 7 to 15 years of normal use depending on how often the door opens. Extension springs tend to wear out a bit faster, usually within 7 to 12 years.
But Los Gatos has a few factors that accelerate wear. The town sits at the base of the Santa Cruz Mountains and experiences a Mediterranean climate. mild and mostly dry in summer, but noticeably wetter in winter. Humidity levels hit around 80% in January, and that moisture is hard on metal hardware. As one local service provider notes, cable problems in particular are common here because the area's climate variations cause metal components to expand and contract, leading to premature wear. Springs face the same stress.
Then there's the housing stock itself. Many Los Gatos neighborhoods. Almond Grove, Glen Ridge, Belwood, Surrey Farms. feature homes that are 30 to 50 years old or older. Ranch-style homes from the 1960s and 70s are common throughout the flatter east and north parts of town, and a lot of those garages still have the original spring hardware. If you're in one of those homes and haven't had your springs inspected recently, there's a real chance they're overdue.
Warning Signs Your Springs Are Failing
You don't always get a dramatic bang. Sometimes springs fail gradually. Watch for these signs:
- The door feels unusually heavy when you try to lift it manually. Disconnect the opener and try lifting by hand. it should rise smoothly and stay put at about waist height. If it drops or takes real effort, the springs aren't doing their job. - Gaps in the torsion spring coils. Healthy torsion springs sit tightly wound above the door. If you see a gap or separation in the coil, the spring has snapped. even if the door is still moving (just barely, with the opener straining). - The door opens crooked or lopsided. This usually means one spring has failed while the other is still holding. It puts enormous strain on the opener motor and cables. - Squealing or grinding at the top of the door's travel. Springs that are losing tension often produce noise before they fail completely. - The opener runs but the door barely moves. The motor isn't designed to lift the full weight of the door. the springs do most of the work. If the springs are gone, the opener will struggle or stop entirely.

Torsion vs. Extension Springs: Which Do You Have?
Most newer Los Gatos homes and remodeled garages use torsion springs. a single horizontal spring mounted above the door on a metal bar. They're safer when they break (they stay on the bar rather than flying across the garage) and generally last longer.
Older homes often have extension springs. a pair of springs running along the horizontal tracks on each side of the door. They're more affordable upfront, but when they snap, they can release with enough force to cause serious injury or damage. If your Los Gatos home still has extension springs and they're reaching end of life, it's worth asking about converting to torsion. the upgrade typically runs $400 to $800 but pays off in safety and longevity.
What Does Spring Replacement Actually Cost?
Here's the honest breakdown for the Los Gatos area:
- Single torsion spring replacement: $150,$350, including parts and labor - Replacing both torsion springs (recommended): $300,$540 for most standard doors - Extension spring replacement: $120,$200 per spring - Heavy or custom doors (think solid wood carriage doors common in the hillside estates above Los Gatos): costs run higher, sometimes $400,$600+ - Emergency/after-hours service: typically adds $50,$100
One thing reputable technicians will always recommend: replace both springs at the same time, even if only one has broken. The springs were installed together and have the same wear. Replacing just one leaves the other spring. which is nearly as worn. ready to fail within weeks or months. You'll pay another service call fee and put more stress on your opener in the meantime. It's not worth it.

Why DIY Is a Hard No on This Repair
This isn't false modesty. garage door spring replacement is legitimately dangerous. Torsion springs store enormous amounts of energy under tension. Improper handling can cause the spring to release suddenly, which has caused serious injuries and worse. Professional technicians use specialized winding bars and follow precise procedures. The risk here genuinely outweighs the cost of hiring a pro.

Frequently Asked Questions
How long do garage door springs last in Los Gatos?
Most torsion springs last 7 to 15 years depending on usage and the local climate. Los Gatos's wet winters and temperature swings between seasons can accelerate metal fatigue, so springs in older homes here may reach end of life on the shorter end of that range.
Can I still use my garage door if one spring is broken?
Technically the opener may still move the door, but you shouldn't use it. Operating with a broken spring puts severe strain on the opener motor and cables, and the door is effectively unbalanced. which creates a safety hazard. Disconnect the opener and call for service.
Should I replace one spring or both?
Always replace both at the same time. Springs are installed in pairs and wear at the same rate. Replacing only the broken one leaves the other near failure, and you'll likely need another service call. and pay for labor again. within a few months.
