Snapped Garage Door Springs in Duarte: Why It Happens & What to Do
2026-07-05 7 min read
A snapped garage door spring is one of the most common emergencies we see. Your door suddenly won't open, won't close, or hangs lopsided. The spring has given out. This happens because springs wear down over time, usually after 7 to 9 years of daily use, and when they finally break, they do it without warning. Replacing a snapped spring costs between $150 and $400 per spring, depending on the type and your local market in Duarte.
Why Springs Snap (And It's Not Your Fault)
Garage door springs are under constant tension. A typical residential door weighs 300 to 400 pounds. The springs counterbalance that weight so the opener doesn't have to lift it alone. Every time you open and close your door, the springs cycle. Over thousands of cycles, the metal fatigues. Cracks form. Then one day, the metal gives way completely.
I've walked into garages where homeowners thought they caused the failure by not lubricating the door or letting it sit unused. That's not how it works. Springs fail due to metal fatigue, not neglect. Cold weather in the San Gabriel Valley can accelerate failure too. When temperatures drop, metal contracts, adding stress to weakened springs.
There are two main types you'll encounter: torsion springs and extension springs. Torsion springs sit above the door and twist to provide lift. Extension springs run along the sides and stretch. Torsion springs are more common in modern homes and last slightly longer. Both types fail the same way: metal fatigue, no exceptions.
The Immediate Danger
Here's what worries me most: a snapped spring creates a safety hazard. If only one spring breaks on a two-spring system, the door becomes unbalanced. It can bind, jam, or fall unevenly. The opener can't compensate for the missing tension. Worse, if you try to open the door manually after a spring breaks, you're lifting 300+ pounds with your hands. People have been seriously injured this way.
Never attempt a DIY repair on broken springs. The tension stored in these components can cause the spring to snap again and injure you. This is one of the few garage door problems where professional service isn't optional; it's a safety requirement.
What to Do Right Now
If your door won't open and you suspect a snapped spring, stop trying to force it. Call for emergency service immediately. Garage Door Duarte offers same-day service across Duarte and the surrounding area. Don't risk your safety or damage the opener by forcing a stuck door.
When you call, describe what happened. Did you hear a loud bang? Is the door completely stuck or moving unevenly? This information helps technicians prepare. Most snapped spring jobs take 1 to 2 hours to complete, including inspection and replacement of both springs (we always replace both, even if only one failed, since the second is likely near failure).

Cost & Timing for Spring Replacement

Torsion springs cost $200 to $400 per spring. Labor typically adds $100 to $200. Most homeowners pay $350 to $600 for a complete repair when both springs are replaced.

If you've neglected routine maintenance, a snapped spring might be the wake-up call to start. Read our guide on garage door tune-up and lubrication in Duarte to prevent premature wear on your replacement springs. Proper lubrication extends spring life by a year or two.
Prevention for Next Time
You can't stop springs from eventually failing, but you can extend their lifespan. Keep the door lubricated with silicone spray every three months. Avoid forcing the door if it sticks. Have annual safety inspections to catch worn springs before they snap. Visit our services page for spring replacement to learn more about what's available.
A snapped spring is frustrating and stressful. The good news is the fix is straightforward and affordable. The bad news is it often can't wait. If your door is stuck right now, don't delay. The longer a snapped spring sits unrepaired, the more stress it places on the opener and other components.

Frequently Asked Questions
How do I know if my spring is snapped vs. just stuck? If the door won't open even with the opener running, and you heard a loud bang recently, your spring is likely snapped. A stuck door usually moves slightly or makes grinding sounds. Springs fail suddenly and silently.
Can I open my garage door manually after a spring breaks? No. Never attempt to lift a garage door with a broken spring manually. You're lifting 300+ pounds without the spring's support. Serious injury is possible. Wait for professional service.
Will my garage door opener break if I keep using a snapped spring? Yes. The opener will strain to compensate for missing spring tension. The motor can burn out, and the drive mechanism can fail. Stop using the door immediately and call for repair.
How long do garage door springs actually last? Most springs last 7 to 9 years with normal use. Some last 10 years if maintained and used gently. Climate and frequency of use affect lifespan. Springs in the San Gabriel Valley endure temperature swings that shorten life slightly.
Is it cheaper to replace just one broken spring? No. We always recommend replacing both springs together, even if only one failed. The second spring is nearly as worn and will fail soon. Replacing both at once saves money and prevents a second emergency.
