Why New Boston Winters Are Hard on Garage Door Springs (And What to Do About It)
2026-03-30 7 min read
If you've ever walked out to your garage on a bitter January morning and found the door won't budge, there's a good chance a spring gave out overnight. It's one of the most common calls we get here in New Boston every winter. and it almost never happens at a convenient time.
Understanding why it happens, and what warning signs to watch for, can save you from being stranded in your own driveway when temperatures are sitting in the teens.
What New Boston's Climate Does to Garage Door Springs
New Boston sits in Hillsborough County with a classic New Hampshire humid continental climate. Winters here are genuinely cold. January averages a high of just under 30°F and regularly dips into the teens at night. What makes this especially tough on hardware isn't just the cold itself. It's the cycle.
A mild afternoon might warm things up to 40°F, and then overnight temps plunge back below freezing. That daily expansion and contraction puts cumulative stress on every coil of steel above your garage door. Think of bending a paperclip back and forth. each cycle creates microscopic damage that builds invisibly over months.
By late February and into March, when New Boston weather delivers some of its most unpredictable swings, springs that have been quietly weakening since November are often right at their breaking point. That's why so many failures happen at the tail end of winter rather than during the coldest nights of December.
Torsion springs. the horizontal coil mounted above the door. are especially vulnerable because they're under constant tension. The steel contracts when it's cold, increasing the load on a spring that's already near its cycle limit. Add in the fact that cold weather causes lubricants to thicken, rollers and hinges to stiffen, and the door itself to feel heavier, and the springs are being asked to work harder at exactly the moment they're most brittle.

Warning Signs Your Springs Are in Trouble
Springs rarely fail without sending a few signals first. Here's what to pay attention to:
The Door Feels Heavier Than Usual
If your opener seems to be straining, or the door feels unusually heavy when you lift it manually, the springs are losing their ability to counterbalance the door's weight. A standard residential garage door can weigh 200 to 300 pounds. the springs do the heavy lifting so your opener doesn't have to.
Unusual Sounds
Creaking, popping, or a loud bang from the garage. even when you're not operating the door. are serious red flags. A snapping spring makes a noise you won't forget. Squeaking during operation indicates the springs are under stress, and that stress is only going to increase with each cold morning.
Uneven Movement
If one side of your door rises higher than the other, or the door jerks and stops partway through its cycle, one spring may already be failing. The remaining spring is now carrying the full load. and it won't last long under those conditions.
A Visible Gap in the Coil
Walk to the back of your garage and look at the spring above the door. A clear separation or gap in the coil means it's already broken. Do not attempt to operate the door if you see this.
What You Should. and Shouldn't. Do
Lubrication is the one maintenance task homeowners can handle themselves. Use a dedicated garage door lubricant spray (not WD-40, which can actually increase friction when it dries out in cold conditions) on the spring coils, hinges, and rollers each fall. This helps slow corrosion and keeps parts moving with less resistance through the winter months.
Spring *replacement*, however, is a job for a professional. full stop. Torsion springs store enormous amounts of tension. If a spring releases unexpectedly during replacement, the result can be severe injury. Even experienced DIYers get seriously hurt attempting this. Our services page covers what a proper spring inspection and replacement involves if you're curious about the process.
Proactive Replacement Beats Emergency Calls
Most standard torsion springs are rated for around 10,000 cycles. If your garage door opens and closes four times a day, that's roughly seven years of use. If your springs are approaching that age. or if you moved into your New Boston home and have no idea when they were last replaced. a proactive swap before next winter is the smarter call. Planning ahead is consistently less expensive than an emergency weekend service call.
For homeowners in nearby Goffstown or Bedford who may be dealing with the same seasonal wear patterns, the advice holds equally well. Hillsborough County winters are no joke for garage hardware.
When to Call
If you're seeing any of the warning signs above, don't wait for a complete failure. A broken spring can cause the door to drop suddenly, damage your vehicle, and create a security risk since the door may not close or lock properly.
New Boston Garage Doors offers spring inspections throughout the area. Getting eyes on your system now. especially coming out of a hard winter. is the kind of preventive step that pays for itself. Reach out to schedule a visit before the issue becomes an emergency.
Frequently Asked Questions
Q: How do I know if I have torsion springs or extension springs? Torsion springs are a single horizontal coil mounted on a metal bar directly above the closed garage door. Extension springs run along the horizontal tracks on either side of the door and stretch when the door opens. Both types are under high tension and require professional replacement.
Q: Can I still use my garage door if a spring is broken? Technically, your opener may try to run, but operating a door with a broken spring puts enormous strain on the opener motor and can damage it. It also makes the door unpredictable and potentially dangerous. It's best to leave the door closed and call for service.
Q: How much longer do high-cycle springs last compared to standard ones? Standard builder-grade springs are typically rated for around 10,000 cycles. High-cycle springs can be rated for 20,000 to 30,000 cycles or more. effectively doubling or tripling the usable lifespan in a busy household. In a climate like New Boston's, the upgrade is often worth the modest additional cost.
