If you've ever walked into your garage in the morning and found the door completely dead. won't budge, opener straining, nothing. there's a good chance a spring has failed. It's one of the most common calls we get at Garage Door San Jose, and it tends to happen at the worst possible time. Understanding what springs do, why they fail, and what to do about it can save you a lot of stress.
Your garage door can weigh anywhere from 130 to well over 200 pounds. Torsion springs and extension springs are what make it possible to open and close that weight dozens of times a week without burning out your opener. They counterbalance the door's weight. without them, your opener would be doing all the heavy lifting alone and would burn out fast.
Torsion springs mount horizontally above the door opening on a metal tube, while extension springs run along the horizontal tracks on either side. Most newer San Jose homes use torsion spring systems, but a large portion of the city's older housing stock. particularly the mid-century ranch homes throughout Cambrian, Blossom Valley, and the Berryessa area. still have the original extension spring setups installed decades ago.
Springs are rated by cycles. one full open-and-close movement equals one cycle. Standard springs typically run 10,000 to 15,000 cycles. If your household uses the garage door four times a day (not unusual for a busy Silicon Valley commute), you're burning through roughly 1,400 cycles a year. That puts standard springs at a lifespan of about 7,10 years.
But San Jose has a few local factors that accelerate wear:
- Summer heat: Neighborhoods like Almaden Valley, Evergreen, and south San Jose regularly see temperatures in the mid-90s to low 100s from June through September. That sustained heat accelerates metal fatigue in torsion springs, which is why the spring replacement rate here tends to be higher than in cooler coastal cities. - Bay Area micro-climate humidity: The marine layer that rolls in from the Bay can introduce enough moisture to start corroding spring coils. especially on older, uncoated springs. - High usage cycles: Tech-commute households in San Jose often rack up significantly more daily open/close cycles than the national average, shortening spring lifespan faster than most people expect.
If you've already read our post on how San Jose's climate damages garage doors, this context will sound familiar.
Don't wait for a complete failure. springs often give warning signs first:
- The door feels unusually heavy when you disconnect the opener and try to lift manually. A properly balanced door should stay in place when lifted halfway up. - The door opens unevenly or looks tilted. one side higher than the other. This usually points to a broken or worn extension spring on one side. - You hear a loud bang from the garage, sometimes described as a gunshot sound. That's almost always a torsion spring snapping under tension. - Visible gaps in the spring coil. if you look at the torsion spring above your door and see a clear separation in the coil, it's broken. - The opener strains, slows, or reverses without completing the open cycle.

Torsion springs are the thick coiled springs centered above the door opening. They're heavier-duty, longer-lasting, and safer when they break. the cable system keeps them from flying across the garage. Most homes built after the 1980s use them.
Extension springs are the thinner springs that stretch along each horizontal track. They're more common in older homes and one-piece tilt-up doors. They work fine when maintained, but they tend to be noisier and require safety cables to prevent a dangerous snap if they break.
If you're in one of San Jose's older neighborhoods and still running original extension springs, upgrading to a torsion system during your next replacement is worth discussing with a technician.
This is a common question. Here's the honest answer: if one spring breaks and the other is the same age, the second one is probably close to the end of its life too. Replacing both at the same time costs more upfront, but it saves you from a second service call within months. and avoids the imbalance that comes from one new spring paired with one worn-out spring. Most reputable technicians will recommend replacing both, and that's legitimate advice, not just an upsell.
In the South Bay Area, spring replacement typically runs in the range of $150,$350 per spring, with the total job (labor plus parts) commonly falling between $250 and $500 for a full replacement of both springs. San Jose and the South Bay sit among California's higher-cost markets for garage door labor, so budget accordingly.
The price varies based on: - Spring type (torsion costs more than extension) - Spring size and weight rating (heavier doors need stronger springs) - Whether you're upgrading to high-cycle springs rated for 25,000+ cycles
High-cycle springs cost slightly more upfront but can more than double the lifespan. a smart investment for households with heavy usage.
Garage door springs are under extreme tension. A torsion spring holds enough stored energy that if it releases unexpectedly. which it can during improper installation. it can cause serious injury. The specialized winding bars, proper torque measurements, and cable hardware involved are not the kind of thing you pick up from a YouTube video. This is one repair where calling a professional isn't overcautious. it's just the right call.

Most torsion springs are rated for 10,000,15,000 cycles. Given the combination of heavy commuter use and San Jose's summer heat accelerating metal fatigue, many homeowners find they're replacing springs every 5,8 years. Upgrading to high-cycle springs rated for 25,000+ cycles at replacement time can significantly extend that window.
Technically the door may still move, but you shouldn't use it. Operating a door with a broken spring puts enormous strain on the opener motor and can damage the opener, cables, and other hardware. It's also a safety risk. Stop using it and call a technician.
For most San Jose homeowners. especially those in older homes in neighborhoods like Cambrian or Willow Glen. yes. Torsion springs last longer, operate more quietly, and are significantly safer when they fail. The upgrade costs more upfront but typically pays for itself in longevity and reduced maintenance.
