Snapped Garage Door Springs in Westborough: Why It Happens & What to Do

2026-09-15 7 min read

Serving Westborough, we see this problem again and again: a garage door that won't budge because a spring has snapped. A broken spring is one of the most common garage door failures, and it's also one of the most dangerous to ignore or attempt yourself. Here's what you need to know about springs, why they fail, and when to call a professional.

What a Garage Door Spring Does (And Why It Matters)

Your garage door weighs 300 to 500 pounds. A single spring doesn't hold it up on its own. Instead, springs work under extreme tension to balance that weight so your opener can lift the door smoothly with minimal effort. There are two main types: torsion springs (mounted above the door on a shaft) and extension springs (mounted on each side, stretching and contracting). Most residential doors in Westborough use torsion springs because they last longer and perform more reliably.

Springs typically last 7 to 9 years, depending on use and maintenance. A door that opens and closes 10 times daily will wear springs faster than one used 3 times daily. Once a spring snaps, your door won't operate safely, and the opener will strain trying to lift dead weight.

Why Springs Break

Rust and corrosion are the biggest culprits in New England. Winter salt spray and humidity corrode the steel, weakening it from the inside. A spring that's already weakened by rust finally gives way during a normal open or close cycle.

Lack of lubrication accelerates wear. Springs need periodic oiling to reduce friction and prevent metal fatigue. Many homeowners don't realize this until it's too late. Age alone is another factor: springs have a finite cycle lifespan, usually 10,000 to 15,000 cycles. After that, failure is inevitable.

Why You Shouldn't Fix It Yourself

A snapped spring is under massive tension. Replacing it requires specialized tools, expertise, and safety equipment. Attempting a DIY repair puts your hands, face, and body at serious risk of injury. Springs can snap again during installation if not handled correctly. Even loosening the adjusting bolts without the right knowledge can cause the door to fall. Leave spring replacement to trained technicians.

What Spring Replacement Actually Costs

Repair cost varies based on whether one or both springs have failed. A single torsion spring replacement typically runs between $200 and $400, including labor and parts. If both springs are near the same age, replacing both at once is smart because the second one will likely fail soon after the first. Dual replacement costs between $350 and $600.

For extension springs, costs are usually 20 to 30 percent lower. The labor is less complex, but extension springs are generally less common on newer residential doors.

Signs Your Spring Is About to Fail

A healthy spring is invisible. You notice it only when something's wrong. Watch for a loud bang or crack when the door opens or closes. That sound often signals a snapped spring. If the door feels heavier than usual or the opener struggles to lift it, a weakened spring is likely the cause. A door that stays slightly open or drifts down slowly even with the opener engaged also points to spring trouble.

Don't wait for a complete failure. If you suspect spring wear, have it inspected before you get stuck with a non-functional door. For more on garage door openers and how they interact with your spring system, check out our guide to garage door opener maintenance in Westborough.

Prevention and Maintenance

Regular maintenance extends spring life significantly. Professional tune-ups include lubrication, tension checks, and rust inspection. Keeping your garage reasonably dry also helps: moisture accelerates corrosion. In winter, a small dehumidifier in the garage can reduce rust risk.

If you notice rust starting to form on the spring shaft or fasteners, address it early. A light coating of WD-40 or a similar penetrant oil slows corrosion. For detailed guidance on keeping your entire system running smoothly, read about garage door maintenance in Westborough.

Frequently Asked Questions

Q: Can I open my garage door manually if the spring is snapped? A: No. A snapped spring removes the counterbalance, leaving 300+ pounds of dead weight. Attempting to lift it manually risks serious injury. Call a professional instead.

Q: How long does spring replacement take? A: Most spring replacements take 1 to 2 hours, depending on access and whether one or both springs need replacement. A technician can usually complete the job during a single visit.

Q: Should I replace both springs even if only one snapped? A: Yes. Springs wear at the same rate. If one has failed, the other is near failure too. Replacing both avoids a second breakdown shortly after the first repair.

Q: Do I need to replace the cable if I replace the spring? A: Not always, but a technician will inspect the cables during spring replacement. If they show signs of wear or fraying, replacement is recommended for safety.

Q: What's the difference between torsion and extension springs? A: Torsion springs mount horizontally above the door and twist to balance weight. Extension springs mount vertically on each side and stretch. Torsion springs are more durable and common on newer residential doors.
