Garage Door Springs in Burbank: Why a Snapped Spring Is Dangerous
2026-08-08 7 min read
Here's what most homeowners don't realize about garage door springs: they're under extreme tension, and when one fails, the entire door becomes a 300 to 400 pound liability. I've responded to calls where a snapped spring sent a door crashing down on a car, a bicycle, or worse. In Burbank and across Southern California, spring failure is one of the leading causes of garage door injuries and property damage. Understanding why springs fail and how to spot danger early could save you thousands of dollars and keep your family safe.
How Garage Door Springs Work (and Why They Snap)
Your garage door uses one of two spring systems: torsion springs mounted above the door opening, or extension springs running along the sides. Both bear the full weight of your door and counterbalance it as you open and close. Torsion springs are wound incredibly tight. A single rotation stores enough force to lift a small car. See our guide on garage door springs in burbank: everything you need to know.
Springs are engineered to last between 7 and 9 years under normal use. That's roughly 10,000 to 15,000 open-and-close cycles before metal fatigue takes over. Rust, poor lubrication, manufacturing defects, or even a single hard slam can accelerate failure. When a spring snaps, it happens fast and loudly. You'll hear a bang that sounds like a gunshot.
The Danger of a Snapped Spring
Once a spring breaks, your door opener can no longer lift the door safely. Many homeowners push the button and hear the opener strain as it struggles to raise a 400 pound load with zero counterbalance. This overloads the opener motor and cable system, which can snap next.

The real hazard comes when you try to manually raise a door with a broken spring. The door will crash down suddenly, with nothing to slow its descent. Fingers, hands, arms, and heads have been crushed. Cars parked underneath have been damaged beyond repair. Even if you escape injury, a fallen door traps you inside your garage and compromises your home's security.
Snapped extension springs create a different problem: the door becomes unbalanced and can bind in its tracks. This can cause the opener to work unevenly, forcing one side of the door upward while the other lags behind, warping the frame.
Spotting a Spring Problem Before It Breaks
Check your springs monthly. Look for visible gaps, rust, or oil weeping around the spring mount. Listen for creaking or grinding sounds during operation. If your door feels heavier than usual or moves unevenly, don't ignore it. These are warning signs that a spring is losing tension and approaching failure.

What a Snapped Spring Costs to Repair
The cost to replace a snapped spring typically ranges from $250 to $400 per spring, depending on whether you have one torsion spring or two, and the door size. If the spring failure has already damaged your opener or cable, add another $150 to $300. Getting an estimate upfront prevents surprise bills.
Emergency service costs more. If you need a spring replaced after hours or on a weekend, expect a surcharge. Many homeowners don't budget for this because they don't expect a spring to fail. The best financial protection is preventive maintenance and knowing when to call a professional. Read our guide on the true cost of spring replacement to understand pricing better.
Why You Should Never DIY Spring Replacement
Torsion springs operate under 200 to 400 pounds of tension. A slip, a miscalculation, or a tool failure can launch a spring end across your garage at lethal speed. I've seen self-taught homeowners rushed to emergency rooms. Doctors call these injuries "garage door lacerations." They're severe.
Extension springs are slightly safer to handle, but still dangerous. A worn or partially broken extension spring can snap while you're working on it, causing the same kind of injury.
Professional technicians use specialized tools, safety equipment, and decades of experience. They also warranty their work. If something goes wrong within 30 days, they fix it free. DIY attempts come with zero guarantees and maximum personal risk.
When to Call for Emergency Service
If your door won't open, is stuck halfway, or you heard a loud bang when you tried to use it, stop pushing the opener button. Call for help immediately. Continuing to operate a broken door system risks injury and causes additional damage.

Frequently Asked Questions
How do I know if my garage door spring is about to break? Watch for visible rust, oil leaks around the spring mount, creaking sounds, or a door that feels heavier than normal. Uneven movement or the door moving slower than usual also signals wear. Call a technician if you notice any of these signs before a snap occurs.
Can I open my garage door if one spring is broken? No. Do not attempt to open or close the door manually or with the opener. A broken spring removes all counterbalance, making the door fall suddenly and causing injury or property damage. Call for emergency service immediately.
How long do garage door springs really last? Quality springs last between 7 and 9 years with normal use, roughly 10,000 to 15,000 cycles. Harsh weather, salt air in coastal areas, or frequent use shortens lifespan. Proper lubrication and maintenance can extend that window slightly.
Is spring replacement covered by homeowner insurance? Most homeowner policies do not cover spring replacement because it's considered normal wear and tear. Check your policy document or contact your agent. Coverage varies widely by plan and location.
Why do both springs need replacement even if only one snapped? Because the second spring is the same age and has endured the same cycles. It will fail soon after. Replacing both at once saves labor costs and prevents another emergency in weeks.
