If your garage door isn't opening or you've heard that telltale snap, a broken spring is almost always the culprit. The repair cost for garage door springs in Dunstable typically ranges from $250 to $400 per spring, depending on the type, your door's weight, and labor. I'll walk you through exactly what drives that number so you know what's fair.
Not all springs are created equal. Your garage door likely uses one of two types: torsion springs or extension springs. Torsion springs sit above your door and twist to lift the weight. Extension springs run along the sides and stretch to do the same job. See our guide on garage door openers in dunstable: belt vs. chain, cost, and smart options.
Torsion springs cost more to replace (usually $300 to $400 each) because they're under extreme tension and require professional installation. Extension springs run $150 to $250 per pair because they're simpler to swap out. If you've got a heavier door, expect the higher end of those ranges.
Our team at Dunstable Garage Doors has replaced hundreds of snapped springs, and the most common question is always, "Why so much?" The answer is simple: these aren't hardware store parts. Springs are engineered to your door's exact weight and dimensions, and installation demands skill and safety equipment. One mistake during replacement can cause serious injury.

Several factors shift the final cost. Door weight is the biggest one. A standard single-car door needs lighter springs than a double-car or insulated model. Heavier doors require heavier springs, which cost more.
The age of your system matters too. If your springs are original to a 15-year-old door, both may need replacement soon anyway. A professional inspection can reveal whether a second spring is on its way out. Replacing both at once saves you a service call down the road.
Labor time varies by spring type. Torsion springs take 1 to 2 hours because the job involves careful tension adjustment. Extension springs might take 45 minutes. In Dunstable and surrounding areas like Ashby, most shops charge $75 to $150 per hour for labor.

I see homeowners tempted to save money by replacing springs themselves. I get it. But here's the reality: garage door springs operate under 200 pounds of tension. A snapped spring can slice through skin or worse. Professional technicians use special tools and safety cables to manage that pressure.
When you call us for a same-day estimate, we assess whether you have one or two failing springs. Many doors actually have two springs sharing the load. If one snaps, the second is usually close behind. Replacing just one and ignoring the second is false economy. You'll be calling again in weeks.
If you want to understand your springs better before we arrive, check out our guide on garage door springs types and how they work. It covers torsion versus extension in detail.
Some shops quote low and add fees at the end. Not us. Our estimate includes the spring itself, labor, safety cable inspection, and a basic door balance check. No surprises.
Watch out for shops that don't inspect your second spring or don't discuss balance. A door with unbalanced springs will stress your opener and fail prematurely. That's a hidden cost nobody wants.
If your door is old and needs opener work too, read our breakdown of garage door openers: belt vs. chain, cost, and smart options. Sometimes bundling repairs saves money.
Springs last 7 to 9 years in typical homes, longer if you don't use your door much. If your springs are original and your door is over a decade old, ask about full replacement. New springs plus a new opener might cost $1,200 to $1,800, but you're buying peace of mind and avoiding repeat calls.

How long do garage door springs last? Most residential springs last 7 to 9 years with normal use, roughly 10,000 cycles. Heavy use or poor maintenance shortens that timeline. Annual inspections catch wear before failure.
Can I replace one spring if only one is broken? Technically yes, but not recommended. If one spring failed, the other is usually near the end of its life too. Replacing both saves you a second service call within weeks.
What's the difference between emergency and regular spring replacement pricing? Emergency calls (evenings, weekends, holidays) typically add 25 to 50 percent to the base cost. Scheduling during business hours keeps your expense down.
Do I need to replace my opener if I replace the springs? Not always. A good opener can last 10 to 15 years. During your spring replacement, we inspect the opener. If it's functioning well, it stays.
Why are torsion springs more expensive than extension springs? Torsion springs handle all the weight and require precise tension adjustment during installation. They're engineered parts with minimal margin for error, so material and labor both cost more.
