If you've ever walked into your garage and found the door won't budge, the culprit is almost always a broken spring. After 15 years in this business, I've replaced thousands of them across Danville and the surrounding East Bay. Here's what you need to know: your garage door uses one of two spring types, and understanding which one you have matters for both safety and repair costs.
Your door relies on either a torsion spring or an extension spring to lift that 300+ pound slab of steel and wood. These aren't interchangeable, and the type you have depends on your door's design.
Torsion springs mount horizontally above your garage door opening. They twist and unwind to store energy. Most modern homes in Danville built in the last 20 years have torsion springs because they're safer, more durable, and last 7 to 9 years with normal use. They cost more upfront but require fewer replacements over a home's lifetime.
Extension springs hang vertically on each side of your door tracks. They stretch and contract like rubber bands to lift the door. Older homes and budget installations often use these. They're cheaper initially but wear out faster and pose higher safety risks if they snap.
Springs fail for one simple reason: metal fatigue. Every time your door opens and closes, the spring cycles. A typical spring cycles 10,000 to 15,000 times before it gives out. If you open and close your door three times daily, that's roughly 7 to 9 years of life.
Environmental factors matter too. Danville's hot, dry summers and occasional cold snaps put stress on metal. Rust accelerates failure. Lack of lubrication speeds wear. I've seen springs snap in their fourth year when homeowners skip maintenance, and I've replaced springs that lasted well past nine years because owners kept them oiled and inspected.
A snapped spring usually means your door won't open at all, or it opens halfway then crashes down. This is dangerous. Don't attempt a DIY fix. Your door is incredibly heavy, and a failed spring removes the counterbalance that makes manual lifting possible. We've written before about why DIY spring repairs fail, and the short answer is liability and injury risk.

If you're replacing a snapped spring or planning an upgrade, the choice depends on your door type and budget.
Choose torsion if: you want longevity and safety. Torsion springs are engineered for precision. They wear more evenly. When they fail, they usually fail quietly without the violent snap of an extension spring. Most homes should use torsion.
Extension springs are: the budget option. They work fine for lighter doors or older installations. But they require safety cables running through them. If the spring breaks, the cable catches the spring so it doesn't whip across your garage. Still, the snap is sudden and loud.
The cost difference matters. Torsion spring replacement runs higher, but it's a better value over time. For an exact estimate on your situation, schedule a free quote and we'll tell you same-day pricing.
You can't prevent spring failure forever, but you can delay it. Lubricate your springs and tracks every three months with garage door lubricant (not WD-40, which dries out). Keep your door balanced. A door that's hard to open manually means springs are wearing unevenly.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with average use (three cycles per day). Extension springs wear faster, often lasting 5 to 7 years. Climate, humidity, and maintenance affect lifespan.
Can I replace one spring or do I need both? Springs wear in pairs. If one breaks, the other will follow within months. We recommend replacing both at once to ensure balanced operation and prevent future emergency calls.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly, usually with a loud bang. Your door won't open. A worn spring weakens gradually, making the door heavier to open manually or causing the opener to work harder.
How much does spring replacement cost near me? Torsion spring replacement costs between $200 and $400 per spring, including labor. Extension springs run $150 to $300 per pair. Call 925-441-0387 for an exact estimate based on your door type.
Is it safe to use my garage door with a broken spring? No. A broken spring removes the counterbalance. Your door becomes extremely heavy and dangerous. Don't attempt to open it manually or use the opener. Contact us immediately for emergency service.
