Here's what most homeowners don't realize about garage door springs: they're holding roughly 400 pounds of tension at all times, and when they snap, they do so instantly. No creaking. No slow decline. One moment your door works fine; the next, a spring ruptures and your garage door becomes a half-ton dead weight. In Novato and across the North Bay, we've seen broken springs cause injuries, damage to vehicles, and doors that simply refuse to budge.
Your garage door relies on one of two spring systems. The torsion spring sits horizontally above your door opening and twists to lift the weight. Extension springs hang on either side of the door and stretch as it lowers. Both do the same job: they counterbalance your door's weight so the opener doesn't have to.
The difference matters for safety and repair costs. Torsion springs are more common in newer homes and last longer, typically 7 to 9 years under normal use. Extension springs wear out faster, usually around 5 to 7 years. Neither lasts forever. When one breaks, you'll hear a loud bang (sometimes mistaken for a gunshot), and your door will either fall or refuse to open.
Springs fail because metal fatigues. Every single time your garage door opens and closes, the spring flexes. After thousands of cycles, the metal becomes brittle. A typical household door cycles 3 to 5 times daily, which means your springs endure 1,000 to 1,800 cycles every year.
Temperature swings in Novato winters accelerate this wear. Cold makes metal contract; heat makes it expand. The repeated stress breaks the molecular bonds inside the steel. Rust also eats away at spring integrity. If moisture collects on your springs (common in garages near the coast or in humid areas), corrosion weakens them long before their time.
Poor maintenance speeds everything up. Springs that never get lubricated work harder and fail sooner. If your door sounds squeaky or grinds when opening, that's your springs crying for help.

When a spring breaks, your garage door opener cannot lift the door. The motor may run, but nothing moves. Some homeowners force the issue and burn out their opener, which then costs even more to replace.
If both springs snap, the door becomes a falling hazard. It will crash down on anything underneath: cars, bikes, people. Children and pets are especially vulnerable. This is why a snapped spring is never just an inconvenience. It's a safety emergency.

The smart move is replacing springs before they fail. If your door is over 7 years old and you haven't replaced the springs, do it now. The cost of a same-day spring replacement is far less than the cost of emergency repair plus the damage a falling door causes.
Warning signs include a door that feels heavier than usual, jerky opening motions, or that squeaking sound we mentioned. If your door is opening only halfway, a spring is likely already damaged.
We offer free estimates for spring replacement. Our technicians can assess your current springs, tell you exactly how many cycles remain, and give you a transparent cost quote. View our garage door springs service details to understand what's included.
A single torsion spring replacement typically runs $200 to $400 depending on the spring's quality and your door's weight. If both springs have failed, budget $400 to $800. That's the reason we recommend checking what homeowners actually pay for repair costs in Novato.
Emergency same-day service costs more. A midnight call on a weekend will add $100 to $150 to your bill. Preventing failure by replacing springs on schedule costs far less than an emergency call.

Never attempt to replace garage door springs yourself. This is where we see the worst injuries. Springs under tension can snap without warning and cause severe lacerations or crush injuries. Torsion springs especially should only be handled by certified technicians with proper tools.
Don't ignore a snapped spring hoping the problem goes away. It won't. Your door will get heavier, your opener will fail, and your family's safety declines daily.
How long do garage door springs typically last? Torsion springs last 7 to 9 years; extension springs last 5 to 7 years. Lifespan depends on use frequency, climate, and maintenance. Regular lubrication extends life by 1 to 2 years.
Can I drive under a broken spring? No. Never drive under a garage door with a broken spring. The door could fall without warning and crush your vehicle or injure anyone underneath.
What's the difference between a snapped spring and a loose spring? A snapped spring breaks completely and prevents the door from moving. A loose spring creates noise and jerky motion but the door still operates. Both need professional repair.
Why does my new spring break so quickly? Low-quality springs fail faster. Garage Door Novato uses commercial-grade springs rated for 10,000+ cycles. Cheap springs fail at 5,000 cycles.
Is spring replacement covered by my garage door warranty? Most warranties cover springs for 2 to 3 years. After that, replacement is out of pocket. Check your paperwork or call us at 415-965-6754 to verify your coverage.
