A customer called last Tuesday morning. His garage door wouldn't budge. No noise, no grinding, nothing. Within five minutes, I knew: snapped torsion spring. It's the call I take at least twice a week around Marlborough and the surrounding towns. A broken spring is not something you fix yourself. Here's exactly what you need to know.
Your garage door weighs 300 to 500 pounds. Two springs balance that weight so your opener only has to lift about 10 pounds. When one snaps, the math breaks instantly.
You'll hear a loud *pop* or *bang* from the garage. Sometimes it happens during operation. Other times, you'll just notice the door won't open at all, even if the opener sounds fine. The remote clicks. The motor runs. Nothing moves. That's the telltale sign.
Don't force it. Don't hit the opener button repeatedly. The broken spring has already shifted all the load onto its partner or onto your opener's motor, and pushing it harder only causes more damage.
Most residential garage doors in Marlborough use torsion springs. These are the heavy-duty coils mounted horizontally above your door. They're engineered for 7 to 9 years of normal use, roughly 10,000 to 15,000 open/close cycles.
Extension springs run along the sides of your door. They're less common in newer homes but still show up on older installations. Both types fail eventually, but torsion springs are what stop most people in their tracks because they're under immense tension and require serious care during replacement.
You can learn more about keeping springs healthy in our guide to garage door lubrication in Marlborough, which covers the $200 maintenance trick most homeowners skip. Regular lubrication won't prevent failure, but it extends the life significantly.
A typical torsion spring replacement runs $200 to $400 for the part and labor combined in the Marlborough area. If both springs are original and similarly aged, the second one usually fails within months or a year. Smart homeowners replace both at once, even if only one is broken. That's $350 to $600 total.
The cost depends on:
Your door's weight and size. Heavier doors need stiffer springs.
Spring quality. Cheap springs fail faster. We install higher-grade springs that last longer.
Whether you catch it before secondary damage occurs. A broken spring that sits for days can damage your opener, tracks, or cables. That multiplies the repair bill significantly.

Spring replacement looks straightforward on YouTube. It isn't. These springs are under 200 to 300 pounds of tension. If the cable breaks, the spring unwinds violently. I've seen springs punch through drywall. I've seen hands and fingers broken.
Professional technicians use a torsion bar, safety cables, and proper equipment. We're trained to recognize secondary failures. We test everything before handing the door back to you.
If you're handy and curious, there's plenty of garage door maintenance you can handle yourself. Spring replacement is not one of them. Call a professional.
When you call Marlborough Garage Doors after a snapped spring, here's what happens. We ask a few quick questions: Does the door open at all? Do you hear the pop? How old is the door? Then we schedule a visit, usually the same day or next morning.
During the estimate, we'll inspect both springs, check the cables and pulleys, and test your opener. If secondary damage exists, we'll explain it clearly and give you options.

For emergencies outside normal hours, check our emergency garage door service page to see how we handle after-hours calls in the Marlborough area.
Once we install new springs, your door should operate smoothly again. No grinding, no hesitation, no strain on the opener. You'll feel the difference immediately.
Going forward, keep an eye on your springs. If you notice any creaking, slower operation, or the door feeling heavier than usual, that's often a sign the second spring is weakening. Call us before it fails completely.
Most importantly, don't ignore a broken spring. Every day it sits is a day your garage door opener works harder and your home's security is compromised. A few hours and a couple hundred dollars now beats a full replacement or a break-in later.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (10,000 to 15,000 cycles). Extension springs often fail sooner. Harsh weather, frequent use, and poor maintenance shorten lifespan significantly.
Can I replace just one broken spring? Technically yes, but not recommended. If one spring is original and has failed, its partner is likely near the end of its life. Replacing both at once prevents a second failure weeks later and costs only slightly more.
Why is spring replacement so expensive? The labor is specialized and carries safety risk. Springs are under extreme tension, and improper handling causes injury or property damage. Professional equipment and expertise justify the cost.
What should I do if my spring breaks at night? Don't attempt to open the door. Call an emergency service provider who covers Marlborough. Some companies, including ours, handle after-hours emergencies. Your garage door won't open safely until springs are replaced.
Can weather affect spring failure? Yes. Cold temperatures make metal brittle and reduce spring flexibility. Winter sees more spring failures in Connecticut. Regular inspection and lubrication help, but age is the primary factor.
