Why Garage Door Springs Break in Hebron's Late Winter: And What to Do About It
2026-03-28 7 min read
If you've ever walked into your garage on a cold March morning in Hebron and heard a loud bang. only to find your door won't budge. you already know what a broken torsion spring feels like. It's one of the most common service calls we get here in the Lakes Region every late winter, and it's not random bad luck. There's a real reason it happens at this time of year, and understanding it can save you from being stranded in your driveway when you least expect it.
Why Hebron's Climate Is Especially Tough on Springs
Hebron sits in one of the more punishing microclimates in New Hampshire. January average highs barely reach 24°F, with lows dipping to around 11°F. and that's just the average. Add the elevation around Tenney Mountain and the lake effect off Newfound Lake, and you've got a garage environment that sees real temperature swings between night and day throughout the entire winter.
That matters because garage door springs are made of tightly wound steel, and steel contracts when it's cold. As temperatures drop, the spring becomes more brittle and less flexible, making it more susceptible to snapping under tension. Every time you open and close your door on a cold morning, you're putting a more stressed piece of metal through its paces.
Here's the part that surprises most homeowners: springs don't usually fail in December, when it first gets cold. They fail in February and March, after months of accumulated fatigue. By late winter, the metal has already endured hundreds of freeze-thaw cycles. Microfractures have expanded. The spring that seemed fine at Thanksgiving is now hanging by a thread. One morning, it simply gives out.
Warning Signs Your Springs Are Near the End
Don't wait for the loud bang. Your garage door will usually give you some advance notice if you know what to look for:
- The door feels heavier than usual. Springs counterbalance the weight of the door. When they're weakening, your opener has to work harder. and you'll feel it if you ever lift the door manually. - The door moves unevenly or jerks. One spring failing while the other is still working causes the door to rise or lower at an angle. - You hear squeaking or grinding during operation. This can indicate spring metal is fatigued or corroding. - A visible gap in the spring coil. If you can see a separation in the coil above your door, the spring has already snapped.
If you notice any of these signs, stop using the door with the opener. Continuing to run it can burn out the motor. your opener was never designed to lift the full door weight on its own. Check out our full list of services to understand what a proper spring inspection and replacement involves.
Builder-Grade vs. High-Cycle Springs: Know the Difference
Many homes in Hebron. including the newer construction up around Hebron Country Estates and the older Cape-style homes closer to Hebron Village. were originally fitted with builder-grade torsion springs. These are typically rated for around 10,000 cycles. For a household that opens and closes the garage twice a day, that's roughly 13,14 years. But in a cold-weather climate with heavy use, that lifespan can shrink noticeably.
When it's time to replace, you have options. High-cycle springs rated for 20,000 to 30,000 cycles or more are available, and they're worth the modest upgrade cost. especially if you're in a home where the garage is the main entry point year-round. Springs with powder-coated finishes also resist the rust and surface corrosion that New Hampshire's humid winters accelerate.
If one spring has already broken, it's worth replacing both at the same time. The second spring has gone through the same number of cycles under the same conditions. Replacing just one and leaving the other is usually a short-term fix that sets you up for another service call in a matter of months.

What NOT to Do When a Spring Breaks
This is important: do not attempt to replace torsion springs yourself. This isn't a standard DIY job. Torsion springs store an enormous amount of tension. enough to cause serious injury if the spring releases unexpectedly during removal or installation. Even experienced homeowners who are comfortable with general repairs should call a professional for this one.
Leave the door in the closed position, disconnect the opener if needed, and call for service. Trying to force the door open manually can damage cables, rollers, and the tracks. turning a spring repair into a much larger job.
Timing Your Inspection Before Spring Hits Hard
The best time to have your springs inspected is before they fail. ideally in the fall, before temperatures drop below freezing consistently. An annual check-up lets a technician spot worn coils, apply proper lubrication to moving parts, and flag any components that are approaching the end of their useful life. Homeowners in nearby Plymouth and Bristol who skip this step tend to call for emergency service at the worst possible time: a Sunday morning in January with a car stuck inside.
Reach out to schedule a spring inspection before the next cold snap arrives. a little prevention goes a long way when you're dealing with New Hampshire winters.
Frequently Asked Questions
Q: How do I know if I have torsion springs or extension springs? A: Torsion springs are mounted horizontally above the garage door opening on a metal shaft. Extension springs run along the sides of the door, parallel to the horizontal tracks. Both can break, but torsion springs are more common on heavier residential doors and require professional replacement either way.
Q: Can I still use my garage door opener when a spring is broken? A: It's strongly advised not to. Without the spring to counterbalance the door's weight, the opener motor has to carry the full load. which can damage or burn out the motor. Keep the door closed and call for service.
Q: How long does a spring replacement take? A: In most cases, a professional can complete a torsion spring replacement in a single visit, often within an hour or two, depending on the door setup and whether additional hardware needs attention. The goal is correct installation and proper balance, not just speed.
