Why Garage Door Springs Break in Somersworth Winters (And What to Do About It)

2026-03-30 7 min read

Every late winter and early spring, we get a surge of calls from Somersworth homeowners who walk out to the garage in the morning and find the door won't budge. Nine times out of ten, it's a broken torsion spring. and it's no coincidence it happened in February or March. If you live here, or even over in Rochester or Dover, you already know what New Hampshire winters do to everything metal. Your garage door springs are no exception.

Why Somersworth's Climate Is Especially Hard on Springs

Somersworth sits in a humid continental climate that delivers some of the region's most punishing temperature swings. Winters regularly push down to the mid-teens at night while afternoons can climb back toward freezing. sometimes all in the same day. That constant back-and-forth is the real enemy of your garage door hardware.

Here's what's actually happening: garage door springs are made from tightly coiled high-tensile steel. When temperatures drop, that steel contracts and becomes more brittle. When the garage warms up during the day, the metal expands again. Each one of those cycles. and Somersworth averages over 50 inches of snow per year with near-daily temperature fluctuations through January, February, and March. creates microscopic stress in the metal. The spring isn't breaking all at once. It's being worn down incrementally, cycle by cycle, starting well before the snap you'll eventually hear.

By late February, those months of accumulated micro-damage reach a tipping point. That's why the failure almost never happens during the coldest night of December. it happens after the spring has already survived hundreds of freeze-thaw cycles and simply has nothing left.

Standard Springs Aren't Built for This

Most builder-grade torsion springs installed on homes in this area are rated for roughly 10,000 cycles. about one open and one close per cycle. For a family using the garage twice a day, that's somewhere between seven and ten years under ideal conditions. But Somersworth winters aren't ideal conditions. Cold-weather contraction adds extra tension every time the door operates, and that accelerates wear significantly.

If your home is one of the older Cape Cods or Colonial Revivals common throughout Somersworth and neighboring Rollinsford, there's a reasonable chance the springs on your door are original. and have been quietly accumulating fatigue for years.

Warning Signs to Watch For Right Now

Springs rarely break without giving some advance notice. The problem is that most homeowners don't know what to listen and look for. Here are the real warning signs:

- The door feels heavier than usual. Your opener strains, slows down, or the door feels like it takes effort to lift manually. The spring is losing its ability to counterbalance the door's weight. - Jerky or uneven movement. If one side rises faster than the other, you may have a spring that's partially failed or stretched unevenly. - A visible gap in the spring coil. Look at the torsion bar above your door. A clear separation in the coil means the spring has already snapped. - Loud popping or creaking during operation. These sounds often indicate metal stress at work. the spring is telling you it's under strain. - The door closes faster than normal. Without proper spring tension controlling the descent, a door can drop more quickly than it should, which is a genuine safety hazard.

If you're noticing any of these, this is a good time to review your maintenance checklist and what a professional tune-up actually covers before you end up with a door that won't open at all.

What Happens When a Spring Breaks

A snapped torsion spring is not a minor inconvenience. These springs hold 150 to 200 pounds of stored tension to counterbalance the door's weight. When one fails, the door effectively becomes dead weight. Your opener motor will try to compensate and likely burn itself out in the process. In some cases, the door can drop unexpectedly. which is dangerous to anyone nearby.

This is also why spring replacement is not a DIY repair. The stored energy in a torsion spring is enough to cause serious injury if it releases during installation. Proper replacement requires calibrating spring tension precisely to your door's exact weight and dimensions. A spring that's wound even slightly wrong will either cause the door to fly open or make it too heavy for the motor, stripping the opener's internal gears within weeks. It's a job for someone with the right tools and training. full stop.

For context on how your door's other safety systems connect to spring function, it's worth reading through our guide on manual release mechanisms and keeping your family safe, especially if you ever need to operate the door manually during a failure.

How to Extend Spring Life in a New Hampshire Winter

While no spring lasts forever, there are practical steps that genuinely help:

Lubricate annually, before cold weather hits. Use a silicone-based lubricant or white lithium grease on your springs each fall. Avoid standard WD-40. it's a solvent, not a lubricant, and it actually attracts dirt that accelerates wear. A light coat helps maintain the spring's flexibility and slows rust formation.

Keep the garage slightly above freezing when possible. Even a few degrees of temperature buffer reduces the severity of daily contraction and expansion. If your garage is attached to the house, this matters more than you might think. not just for spring longevity but for the performance of every metal component in the system.

Schedule an annual inspection in the fall. Catching worn springs before winter arrives is far less expensive than an emergency repair on a Saturday morning in January. A planned replacement typically runs significantly less than an after-hours service call, and you're not stranded.

Consider upgrading to high-cycle springs. When it's time to replace, ask about springs rated for 20,000 or 30,000 cycles rather than the standard 10,000. For a household in Somersworth using the garage door twice a day through a hard New Hampshire winter, that upgrade can effectively double or triple the lifespan.

When to Call

If your spring has already broken, don't try to force the door or use the opener. Disconnect the opener and contact a technician. Somersworth Garage Doors handles spring replacements throughout the area, including over in Durham and Hampton, and can typically get to you quickly. The sooner you address it, the less chance the opener motor takes damage from trying to lift a door without spring support.

Get in touch with our team if you're seeing any of the warning signs above, or if your springs are seven or more years old and you haven't had them inspected. It's a short conversation that can save you from a much bigger headache.

Frequently Asked Questions

Q: How do I know if my garage door spring is broken versus another problem? A: The clearest sign is a visible gap or separation in the coiled spring above your door. If the spring looks intact but the door is still acting up. straining, moving unevenly, or feeling heavier than normal. you may have a partially failed spring or an issue with cables and rollers. Either way, disconnect the opener and avoid using the door until a technician can assess it.

Q: Can I still open my garage door manually if the spring breaks? A: Technically yes, but a standard residential garage door can weigh anywhere from 130 to over 300 pounds. Without a functioning spring to counterbalance that weight, lifting it manually is difficult and potentially dangerous. Use the manual release only if you absolutely need to, and only with another person helping to support the door.

Q: How long do garage door springs typically last in New Hampshire? A: Standard springs are rated for around 10,000 cycles. For a household using the garage door twice a day, that's roughly 7,10 years under normal conditions. Somersworth's harsh winters. with frequent freeze-thaw cycles and average snowfall over 50 inches. can shorten that lifespan. If your springs are approaching the seven-year mark, it's worth having them inspected before another winter sets in.
