A snapped garage door spring means your door won't open, and it's genuinely unsafe to force it. You need professional help immediately, not a weekend project or a YouTube tutorial. In our years serving La Puente, we've seen homeowners injured or trapped when they tried to handle this alone.
Garage door springs work under extreme tension. A single torsion or extension spring holds 200+ pounds of force on each side of your door. When one fails, that tension releases violently. Your door becomes a 300-400 pound dead weight that no opener can lift.
Attempting to lift it manually risks crushed fingers, wrists, or worse. The spring itself can whip across the garage with enough force to cause serious injury. This isn't the same as a squeaky hinge or a slow opener. This is a structural failure that demands immediate attention.
Torsion springs wind around a rod above your door. Extension springs run along the sides. Either type can snap, but the danger is identical. You'll hear a loud bang, followed by your door refusing to budge. Some homeowners notice the cable has gone slack or see a visible break in the spring itself.
Both failures require professional replacement, not repair. A snapped spring cannot be rewound or patched. It must come out completely and be replaced with an exact match for your door's weight and size.
When you contact Garage Door La Puente for a snapped spring, we'll ask your door's age, size, and whether it's a single or double car. That information determines the replacement spring and helps us give you an accurate estimate over the phone. Most spring replacements take one to two hours.
We arrive with the correct replacement spring, tools, and safety equipment. Our technicians will disconnect the broken spring, remove it, install the new one, and test your door thoroughly. A good professional will also check your cables, rollers, and opener while we're there, since a snapped spring often signals that other components are aging too.

The cost of a replacement varies based on spring type and your door's specifications. You can expect somewhere between $250 and $500 for parts and labor, though heavier doors or dual springs cost more. We'll provide an estimate before starting any work.

Online videos show spring replacement as straightforward. It is not. A spring under tension can snap while you're working on it. Even if you manage the installation, improper tension causes your door to fall too fast or not open at all. Misaligned springs wear out your cables and opener faster, costing you thousands more in repairs later.
Insurance rarely covers DIY injuries. If you slip, get struck, or crush your hand, you're responsible for your own medical bills. A professional carries liability insurance and workers' compensation. We're trained to handle tension safely and know exactly how to balance your door so it operates smoothly for years.

Don't use your garage door if a spring is snapped. Every time you try to open it, you risk damaging the opener or worsening the cable. Treat it as a temporary closure and let your car sit outside until we fix it. This is one of the few garage door issues that truly qualifies as urgent.

How long does a garage door spring last? Most torsion and extension springs last 7 to 9 years with normal use. Opening and closing cycles wear them out gradually. Springs in coastal areas like parts of the San Gabriel Valley may fail sooner due to salt air and humidity.
Can I open my garage door manually if the spring is broken? No. A snapped spring removes the counterbalance that makes manual lifting possible. Your door will be too heavy to lift safely and could injure you or your property.
How much does a garage door spring replacement cost? Typical replacement cost ranges from $250 to $500, depending on spring type, door weight, and whether you have a single or double spring. We'll provide an exact estimate after inspection.
What's the difference between a torsion and extension spring? Torsion springs coil around a rod above your door and twist to hold tension. Extension springs run horizontally along the sides and stretch. Both fail eventually, and both require professional replacement.
Should I replace both springs even if only one broke? Yes. If one spring has failed, the other is usually near the end of its life. Replacing both prevents a second failure weeks later and ensures balanced door operation.
