Garage door springs in Watertown come in two main types: torsion and extension. Torsion springs sit above your door and twist to lift it. Extension springs run along the sides and stretch. Which one you have matters enormously because they fail differently, cost different amounts to replace, and carry different safety risks. A snapped spring isn't just an inconvenience. It's a safety hazard that demands immediate attention.
Your garage door weighs 300 to 500 pounds. Without springs, that weight would crash down without control. Springs balance the load so your opener uses minimal force. They're the hardest-working part of your entire system, cycling thousands of times per year. Most springs last 7 to 9 years with normal use. After that window, failure becomes likely, not just possible.
I've seen homeowners ignore warning signs: a door that moves slower than usual, a loud bang from the garage, or visible gaps in the spring. Then comes the call. The door won't budge. The opener makes noise but nothing happens. Sometimes a spring has already snapped, and they didn't hear it because they were inside.
Torsion springs mount horizontally above your door on a metal rod. They store energy through twisting motion. When you open the door, the springs unwind and help lift it smoothly. When you close it, they wind back up and control the descent.
Torsion springs are the industry standard in Watertown and across Massachusetts because they're durable and predictable. They last longer than extension springs. They're also safer because they're contained within a shaft, so if one breaks, the broken coil doesn't whip across your garage.
The tradeoff: torsion spring replacement costs more. A professional needs special tools to safely wind and install them. The springs themselves are pricier too. But that investment buys you reliability and fewer repairs over time.

Extension springs run along each side of your door's opening. They stretch as your door opens and contract as it closes. They're cheaper upfront than torsion springs and slightly easier to replace, which lowers labor costs.
Extension springs require safety cables running through them. If a spring snaps, that cable should catch the broken spring and prevent it from flying across your garage. The cable is critical. Homes without these cables have seen serious injuries. A broken spring with no safety cable can snap like a whip and cause deep cuts or worse.
If you have extension springs, verify those safety cables are in place. If they're missing or damaged, call a professional immediately. This is non-negotiable.
Springs don't just give up randomly. They fail because of metal fatigue. Every cycle weakens them slightly. Rust accelerates the process dramatically. Watertown's winters bring salt spray that corrodes metal. Springs exposed to damp, unheated garages corrode faster than those in climate-controlled spaces.
Oversized or undersized springs fail faster too. A door that's too heavy for its springs will wear them out in half the normal time. Improper maintenance speeds failure. Springs need periodic lubrication to reduce friction.

You'll hear it. A loud bang or crack, often loud enough to startle you. Your door will feel heavier. The opener may struggle or refuse to open the door at all. Manual operation becomes impossible or extremely dangerous.
Never try to force a door open with a broken spring. The counterbalance is gone. The door could slam down and cause serious injury. Don't call a general handyman either. Spring replacement requires specialized knowledge and tools.
Contact Watertown Garage Doors or another licensed professional for a same-day estimate. We can assess whether repair or replacement makes economic sense for your garage door spring repair cost.
Spring failure doesn't happen during business hours. It happens at night when you're heading out, or on the coldest morning of winter. That's why same-day service exists. A qualified technician can diagnose your issue, order the correct springs if needed, and have your door operational again quickly.
When you call, describe what you heard or saw. Did you hear a bang? Is the door stuck halfway? Is it heavier than normal? These details help dispatch the right person with the right parts.

How long do garage door springs last? Most torsion and extension springs last 7 to 9 years with average use (roughly 5,000 to 10,000 cycles). Heavier doors, salty climates, and lack of maintenance reduce lifespan. Regular lubrication extends it.
What's the difference in cost between torsion and extension springs? Extension springs are usually 30 to 50 percent cheaper to buy and install. Torsion springs cost more but last longer and are safer. Overall long-term cost is often similar because you replace torsion springs less frequently.
Can I replace a garage door spring myself? No. Springs carry enormous tension. Improper installation or handling can cause serious injury or death. Always hire a licensed professional. This is one of the few repairs worth the cost.
How do I know if my spring is about to snap? Listen for creaking or squeaking. Watch for the door moving slower than usual. If you see visible rust, gaps, or misalignment, have it inspected immediately. Don't wait for the snap.
What should I do if a spring breaks while the door is open? Leave the door as is. Call a professional immediately. Don't try to operate it. Keep pets and children away from the garage until help arrives.
