A customer called last Tuesday morning. His garage door wouldn't open, and he'd already heard the pop. When I rolled up to his Cupertino home, I found a snapped spring hanging limp above the door. He asked the question I hear almost every week: "What kind of spring was that, and why did it break?" That's exactly what we're covering today.
Your garage door uses one of two spring types: torsion or extension. Both do the same job, but in very different ways. Torsion springs wind up like a clock, storing energy as they twist. They sit horizontally above your door opening and do most of the heavy lifting. Extension springs, by contrast, hang along each side of the door and stretch out like rubber bands to lift the load. Most modern Cupertino homes have torsion springs. They're safer, last longer, and handle the work more evenly.
The difference matters when something fails. A snapped torsion spring usually means the door won't budge. An extension spring breaks and the door can slam shut fast, which is why we always warn people to stay clear.
This depends on the type and your door's weight. Torsion springs typically run between $200 and $400 for parts and labor. Extension springs cost a bit less, usually $150 to $250. If you need same-day service in Cupertino, expect an emergency premium. We've covered the details on pricing in our garage door opener replacement cost guide, which touches on spring-related expenses too.
The real cost killer isn't the spring itself. It's waiting too long. A worn spring puts extra strain on your opener, which can fail next and cost you another $400 to $600. That's why we recommend getting a free estimate before problems stack up.

Springs don't just snap overnight. They fail because they've done their job thousands of times. A typical spring opens and closes your door roughly 10,000 to 15,000 times before it gives out. That usually takes 7 to 9 years. In Cupertino's mild climate, you might stretch that to 10 years if you're lucky, but don't count on it.
You'll notice problems before a complete failure. Listen for squeaking, creaking, or a slow, uneven opening. If the door seems heavier than usual or hangs lopsided, the springs are losing tension. That's your signal to call someone before your door gets stuck and leaves you stranded.
One thing I always tell homeowners: never try to replace springs yourself. These are under extreme tension. Even seasoned techs respect them. We've seen injuries that could have been prevented.
We'll come out, diagnose which spring is failing, and give you a clear cost estimate. If you have a torsion spring, we'll likely replace both at the same time. One's already broken? The other isn't far behind. We'll inspect your opener and cables while we're there, make sure nothing else is about to fail, and get you back in business fast.

How long do garage door springs last? Quality springs typically last 7 to 9 years with regular use. Lifespan depends on the number of cycles, maintenance, and local climate conditions. If you want the full breakdown, read our detailed guide on spring longevity.
Can I replace just one spring? No. If one torsion spring fails, the other is usually close behind. We always recommend replacing both to keep your door balanced and prevent future emergency calls within weeks.
What's the difference between a torsion and extension spring? Torsion springs twist horizontally above the door and are safer with longer lifespans. Extension springs stretch along the sides. Most modern doors use torsion springs because they're more durable and reliable.
How much does a spring replacement cost near me? In Cupertino, typical costs range from $200 to $400 for torsion springs installed, depending on door weight and whether it's an emergency call. Call us at (669) 322-7483 for an exact estimate.
Is a snapped garage door spring an emergency? Yes. A broken spring means your door won't open or may fall unexpectedly. Stop using the door and call a professional immediately to avoid injury or further damage.
