A snapped garage door spring will stop your door cold. The good news: you don't always need to replace both springs or the entire system. Most Yountville homeowners can save hundreds by understanding when a repair makes sense and when replacement is the smarter long-term move.
Your garage door relies on one of two spring types: torsion springs or extension springs. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch. Both carry tremendous tension. A single spring lasts roughly 7 to 9 years with normal use before metal fatigue sets in.
When one snapped spring fails, the question isn't "should I fix it?" but rather "do I fix one or both?" Here's the honest answer: if one is dead, the other is close behind. Springs wear at nearly the same rate. Replacing only the broken one leaves you vulnerable to a second failure within weeks or months, often at the worst possible time.
A single spring repair costs between $150 and $250 in labor plus the part itself. Sounds cheap. But if you're paying a technician to come out, diagnose the problem, and get on a ladder, you're already at the service call baseline. A full replacement of both springs typically runs $300 to $600 total depending on spring type and door size.
The math usually favors replacing both. You avoid the callback, the second service charge, and the frustration of another breakdown. That said, if your springs are relatively new (under 3 years old), a single repair may be justified. Our detailed breakdown of garage door spring costs covers pricing specifics for Yountville homes.
Torsion springs fail more suddenly but last slightly longer overall. Extension springs tend to fray or snap gradually, giving you small warning signs like uneven door movement. If you have extension springs and notice the door pulling to one side, that's usually a sign one is weakening.
Your garage door shouldn't feel heavy when you manually open it (in a power-outage scenario). If it suddenly does, or if the door won't open at all even with the opener running, a snapped spring is the likely culprit. You'll sometimes hear a loud bang or crack from the garage, which is the spring giving way under load.
Never force a garage door with a broken spring. You risk crushing your hands, damaging the door itself, or injuring someone nearby. A safety inspection can catch wear before failure happens.

Spring cost depends on door weight, spring type, and whether you replace one or two. A standard residential door typically uses springs rated for 10,000 to 15,000 cycles. Heavier doors (like those in Napa Valley's newer homes with solid wood panels) require commercial-grade springs, which cost 20 to 40 percent more.
Labor also varies. A technician who arrives within hours charges differently than one scheduling a week out. Same-day emergency service carries a premium, usually $50 to $100 extra. If your door is stuck in the closed position, you're locked out of your garage, so the urgency is real.
Repair a single spring only if: the other spring is demonstrably new (you replaced it recently), your door is under 5 years old overall, or the broken spring is a specialty type that's expensive to stock. Otherwise, replacement of both springs is the owner-operator move. You pay once, you're done, and you sleep better knowing you've got 7 to 9 more years ahead.
Our guide on choosing between repair and replacement covers this decision in more depth. We also offer free estimates on all spring work so you know the exact cost before we touch anything.
A broken spring isn't a "wait and see" problem. It won't heal itself, and the longer your door sits, the more risk you carry. Moisture and weather in Yountville can rust a broken spring, making replacement harder down the road.

How long do garage door springs last? Most residential springs last 7 to 9 years with normal use (roughly 10,000 to 15,000 opening cycles). Heavy-use doors wear faster. Regular maintenance can extend lifespan slightly, but replacement is inevitable.
Can I replace just one spring? Technically yes, but both springs wear together. Replacing only the broken one leaves you vulnerable to failure of the second spring within weeks. Full replacement of both is more cost-effective long-term.
How much does spring replacement cost in Yountville? Both springs typically cost $300 to $600 in labor and parts for a standard residential door. Heavier doors or commercial-grade springs run higher. Call for a free estimate.
Is a snapped spring an emergency? Yes. A broken spring means your door won't open reliably, and forcing it risks injury. Contact a technician immediately rather than attempting DIY repair.
What's the difference between torsion and extension springs? Torsion springs twist above the door; extension springs stretch along the sides. Torsion springs last slightly longer but fail more suddenly. Both need replacement when worn.
