Garage Door Springs in Manchester: What You Need to Know Before They Snap
2026-05-19 7 min read
Here's what most homeowners don't realize about garage door springs: they're under about 200 pounds of tension per coil, and when one snaps, the entire door becomes a safety hazard. I've been responding to spring calls across Manchester and the North Shore for 15 years, and I can tell you that spring failure is the number-one emergency repair we handle. This post covers what happens when springs fail, why replacement isn't a job for the average homeowner, and how to get help fast.
Why Garage Door Springs Fail
Garage door springs are engineered to cycle about 10,000 times before wearing out. For most households, that means springs last roughly 7 to 9 years. But several factors can shorten their life.
Rust and corrosion are the biggest culprits here in New England. Salt air and moisture accelerate spring degradation, especially if you live near the coast or in areas with heavy snow. If you've noticed your garage door slowing down or jerking unevenly, corrosion on the spring coils is often to blame. Cold weather also makes springs brittle, which is why we see a spike in snapped spring calls during winter months.
Lack of lubrication is another silent killer. Springs need regular maintenance to stay flexible. If you want to learn more about proper bearing care and lubrication schedules, our complete guide to bearing lubrication for homeowners covers the details you need.
Impact damage can snap a spring instantly. A car hitting the door, a heavy object falling, or even a bent track can put sudden stress on the spring system. Once that happens, the spring gives out, and your door won't open or close without significant strain on the opener.
Torsion vs. Extension Springs: Know the Difference
Most residential garage doors use one of two spring types. Torsion springs sit above the door and twist to lift the weight. Extension springs run along the sides and stretch to pull the door up. Both designs fail eventually, but torsion springs are more common in newer homes and tend to be safer when they do fail because they're contained above the header.
If your door is older, you likely have extension springs. These springs can snap suddenly and whip across your garage. This is why I never recommend attempting a DIY replacement. The tension involved is extreme, and injuries happen fast.

Cost and Timeline for Spring Replacement
Spring replacement costs vary depending on whether you need one spring or both, and whether your opener needs adjustment afterward. Most single spring replacements in Manchester run between $250 and $400, but if both springs are worn, replacing them together (which we recommend) costs $400 to $600.

Parts availability isn't usually an issue. We stock the most common spring sizes and can often complete the job the same day you call. If your door has a custom spring size, we'll order it and schedule you for the next available appointment.
Why You Should Never DIY a Snapped Spring
I understand the temptation to save money on repairs. But garage door springs are not a DIY project, and here's why.
A snapped spring leaves your door hanging on the opener alone. The opener is designed to lift about 10 pounds of additional weight, not 300+ pounds. If you try to force the door open manually or with the opener, you can burn out the motor or cause the door to crash down unexpectedly. Both scenarios risk serious injury.
The tension required to install or remove a spring safely requires specialized tools and training. We use a winding bar to carefully control the coil tension, and even small mistakes can cause the spring to launch with force. Every year, emergency rooms treat people for spring-related injuries that could have been prevented by calling a professional.

When a spring fails, don't wait. A broken spring puts stress on your opener, door tracks, and cables. The longer you delay, the more expensive the total repair becomes.

Frequently Asked Questions
How do I know if my garage door spring is broken? The door won't open or close smoothly, feels unusually heavy, or you hear a loud snap or twang. The door may also hang unevenly. Don't force it open; call a professional immediately to assess the damage.
Can I replace just one spring if the other is fine? Technically yes, but we recommend replacing both springs at the same time. If one spring has reached the end of its life cycle, the other is likely close behind. Replacing both prevents a second emergency call in a few months.
Is spring replacement covered by homeowners insurance? Most standard homeowners policies don't cover spring replacement as routine maintenance. However, if the spring failed due to impact damage from a covered event, your insurer might help. Check your policy or call your agent to be sure.
How long does a spring replacement take? A typical replacement takes 1 to 3 hours, depending on the spring type and whether both springs need replacement. We'll give you an accurate estimate once we inspect your door.
What maintenance prevents premature spring failure? Regular lubrication, visual inspections for rust or damage, and keeping the track aligned extend spring life. Our maintenance guide for coastal areas details the schedule we recommend for New England homes.
