A customer called last Tuesday asking what a garage door spring replacement would run him. Before I quoted a number, I had to ask the right questions. Spring cost isn't one-size-fits-all, and if someone's quoting you a price without understanding your door, they're not being straight with you. Let me walk you through what actually determines the cost of garage door springs in Cohasset.
The biggest price driver is spring type. Most residential doors use either torsion springs (mounted above the door opening) or extension springs (running along the sides). Torsion springs typically cost more because they're harder to install and require precise balancing. A single torsion spring runs anywhere from $200 to $400 for the part alone, depending on your door's weight and lift cycle.
Extension springs cost less in parts (usually $100 to $200 each) but come in pairs, so you're replacing both. Labor matters too. Installation takes a trained technician 1 to 2 hours, which adds $150 to $300 to your bill depending on complexity.
Door weight and age factor in as well. Heavier doors (like insulated ones common here on the South Shore) need heavier springs. Older doors sometimes have springs built to different standards, making sourcing the exact replacement trickier and potentially more expensive.
I've seen shops charge $500 just for labor on a spring job. That's inflated. At Cohasset Garage Doors, we charge fair labor rates because spring work is technical but not mysterious. You shouldn't feel nickel-and-dimed for knowing what we're doing.
When you snapped your spring (and springs last about 7 to 9 years of normal use, not longer), the door became unsafe to use. A snapped spring removes all support, and using your opener can damage the tracks or cause the door to fall. That's why same-day service matters. If you need garage door emergency repairs, we can typically arrive same-day.

Before any work starts, you need a real estimate. Bring your door size, age, and whether it's insulated. Photos help too. A technician should measure the spring, check the door balance, and inspect the hardware. That's how you get a reliable cost figure.
Budget roughly $300 to $600 for a single torsion spring replacement, or $250 to $500 for extension springs (two springs). If both springs are worn, expect $500 to $1,000 total because springs wear together. Adding hardware (brackets, cables, hinges) can push costs higher if there's rust or damage.

Springs store tremendous energy. A snapped spring under tension can seriously injure you. I've seen YouTube videos of people trying this at home, and it terrifies me. Spring replacement isn't a weekend project. Hire a professional who has the tools, knowledge, and insurance. The few hundred dollars you might save vanishes fast if someone gets hurt.
That's why our complete guide to garage door springs covers types, cost, and replacement timing in detail. It'll help you spot warning signs before a spring actually breaks.
Springs last longer when your door is balanced and lubricated. Misalignment forces springs to work harder and wear faster. Regular garage door maintenance, including lubrication, extends spring life by months or even years.
If your door seems unbalanced, closes crooked, or makes grinding sounds, get it checked. Those are signs a spring is failing. Catching it early beats dealing with a complete snapped spring and emergency repairs.
Spring replacement isn't cheap, but it's necessary. Your garage door springs are safety-critical parts. Don't let cost concerns push you toward a low-ball estimate that cuts corners or promises unrealistic pricing.

How long do garage door springs last? Most springs last 7 to 9 years with regular use (roughly 10,000 to 15,000 cycles). Factors like door weight, humidity, and maintenance affect lifespan. Springs in coastal areas like Cohasset may wear faster due to salt air.
Can I replace just one spring if the other is fine? Extension springs should be replaced in pairs because they wear together. If one snaps, the other is likely close behind. For torsion springs, you can replace one, but many pros recommend both for balance and longevity.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and twist to lift it. Extension springs run vertically along the sides and stretch. Torsion is more durable and safer, but costs more. Extension is cheaper initially but requires two springs.
Is same-day spring replacement possible? Yes, if you call early. Most spring replacements take 1 to 2 hours. We prioritize calls in Cohasset and offer same-day estimates and repairs when parts are in stock and scheduling allows.
How much will spring replacement cost me? Expect $300 to $600 for torsion springs or $250 to $500 for extension pairs, plus labor. Your actual cost depends on door weight, spring type, and any additional repairs needed.
