Snapped Garage Door Springs in Glendora: What to Do Right Now
2026-08-17 7 min read
Most homeowners don't think about their garage door springs until one snaps. Then you're stuck with a door that won't open, a vehicle trapped inside, and a growing sense of panic. A snapped garage door spring is one of the most common emergencies we handle in Glendora, and it almost always happens at the worst possible time. The good news: you don't have to DIY this one, and calling a professional gets your door working again fast.
What Happens When a Garage Door Spring Snaps
Your garage door weighs 300 to 500 pounds. A single torsion spring (or pair of extension springs) counterbalances that weight so your opener motor doesn't burn out after a few months. Springs are under enormous tension. When one snaps, the system loses balance instantly. The door becomes a dead weight.
You'll hear a loud bang or crack. Some people report it sounds like a gunshot in the garage. Don't ignore that sound. If it happened, one of your springs is gone. The door won't open smoothly, or it won't open at all. Trying to force it with the opener can damage the motor or the door itself.
Extension springs fail from age and use cycles. Torsion springs snap from fatigue. Either way, springs last roughly 7 to 9 years under normal conditions. If your door is older, this risk is real. If you hear creaking or see signs of wear, read our guide on when spring replacement becomes necessary before failure occurs to understand the warning signs.
Why You Shouldn't Attempt This Repair Yourself
Springs are dangerous. They're not like replacing a battery or a light bulb. A snapped spring still holds tremendous tension, and the broken ends can whip or snap unexpectedly. We've treated techs who've been hit by recoiling springs, and the injuries are serious.
Second, matching the right spring type and size matters. A torsion spring must have the correct wire gauge, length, and wind direction. An extension spring needs the right pull force. Guessing gets you a door that operates unevenly or fails again within months. It's not worth the risk or the wasted money.

The Cost of a Snapped Spring
Cost varies based on whether you have one or two springs, and which type failed. A single extension spring replacement typically runs $150 to $300. A torsion spring replacement costs $200 to $400 because it's more complex and requires specialized equipment. If both springs failed (common with older systems), budget for both.
These prices include labor, the spring itself, and testing. It's less than you'd spend if you damage the opener trying to work around a broken spring.

What to Do Right Now
If your spring just snapped:
1. Stop using the garage door. Don't press the opener button. Don't try to lift it manually. Let it sit. 2. If a car is trapped inside, you can manually release the opener (a red cord or handle in most units) and carefully lift the door from outside. Go slow. It will be heavy. 3. Call us immediately. We'll dispatch a technician to your Glendora location and get you a time window. Same-day appointments fill fast, but we do our best. 4. Until we arrive, keep the garage closed. This keeps pets and kids out of the space and prevents further damage.
We serve Glendora and the surrounding San Gabriel Valley. Our team handles residential and light commercial doors. When you call, have your door make, model, and the number of springs ready (usually one or two). That speeds up the process.
Prevention: Know the Warning Signs
Springs don't always snap without warning. Before catastrophic failure, you might notice the door opens slower than usual, the opener struggles, or you hear creaking. These are your cues to schedule replacement proactively. It's cheaper and safer than waiting for a snapped spring to trap you.
We recommend a routine tune-up every 1 to 2 years to catch wear early. Our technicians inspect springs, lubricate hinges, and balance the door during a maintenance visit. If replacement is needed soon, we'll tell you up front.

Frequently Asked Questions
How long does spring replacement take? A typical single spring replacement takes 1 to 2 hours, including inspection and testing. If both springs need replacement or if the system is complex, add another 30 to 60 minutes. We call ahead with a time window.
Can I open my garage door manually if a spring is snapped? Yes, but carefully. Most openers have a red cord that disengages the motor. Pull it, then manually lift the door from outside. Move slowly because the door will feel heavier without spring support. Never leave it open unattended.
Do both springs always fail together? Not always. One may snap while the other has years left. However, if springs are the same age, the second one often fails within months. We recommend replacing both if they're close in age to avoid a second emergency call soon after.
Is a snapped spring covered by homeowner's insurance? Rarely. Most policies treat springs as normal wear and tear. Check your policy or ask your agent, but don't count on coverage. Our estimate at (626) 561-2739 will give you a firm number to budget.
Why is spring repair more expensive than other garage door fixes? Springs are under extreme tension and require specialized tools and training to replace safely. The labor cost reflects the skill and equipment needed, plus the danger involved. DIY attempts often cause bigger problems that cost more to fix.
