Garage Door Springs in Foster City: Types, Lifespan, and When to Repair
2026-09-12 7 min read
If you've ever dealt with a garage door that won't budge, there's a good chance a broken spring is the culprit. Garage door springs in Foster City fail more often than most homeowners expect, and when they do, your door becomes a 400-pound paperweight. We're going to walk you through the two main spring types, how long they actually last, and what you should do when one snaps.
What Are the Two Types of Garage Door Springs?
Your garage door relies on one of two spring systems: torsion or extension springs. Both do the same job (counterbalance the door's weight), but they work in completely different ways.
Torsion springs sit horizontally above your door opening. They twist and unwind to lift the door. Most residential doors in Foster City use torsion springs because they're more durable, quieter, and safer. They also last longer. One torsion spring typically handles the entire load, though some doors have two for extra capacity.
Extension springs hang vertically on each side of the door opening. They stretch and contract as the door moves up and down. Extension springs are cheaper upfront, but they wear faster and require more maintenance. Many older homes in the Bay Area still have extension systems, but we usually recommend upgrading to torsion when replacement time comes.
The type you have determines repair cost, replacement frequency, and how quickly we can fix it. Torsion springs generally cost more to replace but save you money over time.
How Long Do Garage Door Springs Last?
Most springs last between 7 and 9 years with normal use. That's roughly 10,000 to 15,000 open-and-close cycles. If you use your garage door four times daily, you'll hit that limit in less than a decade.
Salt air from our proximity to the bay accelerates rust and corrosion. If you haven't lubricated your springs regularly, you're looking at earlier failure. The environment here in Foster City is harder on metal than inland areas, so don't be surprised if your springs wear out faster than the manufacturer claims.
When one spring snaps, the other is usually close behind. Springs fail in pairs, though not always on the same day. If you notice your door is uneven or harder to open, that's a sign springs are weakening. Read our garage door maintenance guide to learn what regular care can prevent.

Why a Snapped Spring Requires Professional Help
Here's the honest truth: don't attempt spring repair yourself. A fully wound spring holds enough tension to cause serious injury. Springs can snap unexpectedly during repair, and the energy release is violent. We've seen people hospitalized from DIY spring jobs that went wrong.
Professional repair takes about an hour for a single spring replacement. If both springs are damaged, expect closer to two hours. Our team at Garage Door Company Foster City brings specialized equipment and years of experience to handle the tension safely. We'll also inspect the rest of your system (opener, cables, rollers) to catch other problems before they become expensive.
The cost to replace a snapped spring typically ranges from $200 to $400, depending on spring type and door size. Extension springs cost less upfront but torsion springs represent better long-term value.

When to Replace vs. When to Repair
If one spring has snapped and your door is under 10 years old, replacement is usually the right call. If both springs are failing or your door is nearing the end of its life, you might consider replacing the entire garage door instead of patching individual components.
A door that's 15 years old with worn springs often has other issues brewing: cable fraying, opener strain, weatherstripping deterioration. Sometimes replacing just the springs delays the inevitable.

Preventing Future Spring Failure
Lubrication matters. Once every three months, apply garage door lubricant to your springs and hinges. This cuts rust formation and keeps metal moving smoothly. Don't use WD-40 or household oil; they attract dust and gum up over time.
Reduce excessive cycling. The more you open and close your door, the faster springs wear. If you're going in and out constantly, make fewer trips or leave the door open longer.
Balance your door monthly. Disconnect the opener, raise the door halfway, and release it. If it falls or rises on its own, springs are losing tension. Call us for an inspection.
Get annual maintenance. A technician can spot weakening springs before they snap, saving you from an emergency repair call.

Frequently Asked Questions
How do I know if my garage door spring is broken? The door won't open, feels heavier than usual, or hangs unevenly. You may hear a loud bang if the spring snaps suddenly. Never force the door open if a spring is broken. Call for professional help immediately.
Can I open my garage door manually if the spring is snapped? You can, but it's dangerous and difficult. A 400-pound door becomes deadweight without spring support. We recommend waiting for professional repair rather than risking injury.
How much does spring replacement cost near Foster City? Single spring replacement ranges from $200 to $400. Torsion springs cost more than extension springs. Get a free estimate from us to see exact pricing for your door type.
Do both springs need to be replaced if only one breaks? Not always, but we recommend it. Springs wear together, so the second one usually fails within months. Replacing both at once saves money and prevents a second emergency call.
How often should I lubricate my garage door springs? Every three months. Use garage door specific lubricant, not household oil. Regular lubrication cuts rust and extends spring life by years, especially in Foster City's humid, salty environment.
