A customer called last Tuesday morning.her garage door wouldn't budge, and the opener was grinding away uselessly. One look told us everything: a snapped spring. Garage door springs in San Anselmo fail quietly until they don't, and when they do, you're stuck. Understanding what these springs do, how long they should last, and when to call a professional is the difference between a quick repair and a dangerous DIY mistake.
Your garage door weighs between 300 and 500 pounds. It doesn't open and close because your opener is strong.it opens because springs counterbalance that weight. Without them, the motor would burn out in weeks, if it worked at all. Two main types handle this job: torsion springs and extension springs.
Torsion springs wind tightly above your door and rotate to release energy as you open it. They're precise, durable, and far safer than extension springs. Most modern homes use them.
Extension springs run along the sides of your door and stretch to store energy. They're cheaper but less reliable and require safety cables because they can snap violently.
The springs in your garage are engineering, not decoration. They're under enormous tension.working on them without proper tools and training can cause serious injury.
Most springs last 7 to 9 years with normal use.roughly 10,000 to 15,000 cycles (one cycle = one open and close). That's not forever. Climate affects this timeline too. San Anselmo's moisture and temperature swings put extra stress on metal, which can shorten lifespan by a year or two.
Some springs promise 20,000 cycles or more, but that's the high end. If you're using your door multiple times daily, you'll see wear faster. Regular maintenance.the kind we cover in our seasonal garage door maintenance guide.can extend life by catching rust and friction early.
When one spring fails, the other isn't far behind. We always recommend replacing both at the same time. It costs more upfront but saves you from a second emergency call in six months.
Springs hold 200+ pounds of tension. When they snap, they can launch parts across your garage, break bones, or worse. We've seen too many homeowners try this and end up in an ER instead of just calling a professional.
The right tools matter: a spring winding bar (not a screwdriver), proper safety glasses, and knowledge of local building codes. Even then, you need experience to diagnose which spring failed and why.

Can I replace just one garage door spring? Technically yes, but we don't recommend it. The remaining spring is now handling all the load and will fail within months. Replacing both at once costs more upfront but saves you money and hassle long-term.
How do I know if my spring is broken? A snapped spring usually means your door won't open, the opener makes grinding sounds, or the door feels heavier than normal. Never force it; call a professional immediately.
What's the difference between torsion and extension springs? Torsion springs wind above the door and are safer, more durable, and last longer. Extension springs stretch along the sides, cost less, but are more prone to sudden failure and require safety cables.
How much does a garage door spring cost in San Anselmo? Torsion springs run $200,$400 per spring plus labor. Extension springs are cheaper but not recommended. Full replacement with labor typically costs $500,$900 for both springs.
