If you've ever walked out to your garage on a January morning in Swanzey and found the door won't budge, there's a good chance your springs are the culprit. It's not a coincidence that it happens in winter. it's physics, and this area's climate makes it worse than most.
Swanzey sits in Cheshire County with a classic humid continental climate. Temperatures regularly swing between 13°F and 81°F over the course of the year, and January average lows hover around 15°F. That's not just cold. that's the kind of cold that changes how metal behaves. Add in the freeze-thaw cycling that happens almost daily through late winter and early spring, and your garage door springs are under constant stress most homeowners never think about.
Garage door springs are made of tightly wound steel, and steel contracts when temperatures drop. As the metal contracts, the spring becomes more brittle and less flexible. making it more susceptible to breaking under the normal tension required to lift your door. When springs are already worn from daily use, that extra cold-weather brittleness can be the final straw.
It's not just one cold snap that does the damage. Each temperature swing. from a frigid overnight low back up to a milder afternoon. forces the spring to expand and contract repeatedly. By late February and March, months of accumulated micro-stress reach a breaking point. This is why so many emergency calls in this region happen in the last stretch of winter, not necessarily during the coldest nights in December.
There's another factor: when rollers, hinges, and weatherseals stiffen in the cold, the door itself becomes harder to move. That added resistance transfers directly to the springs, forcing them to work harder on every single cycle. If your springs are already approaching the end of their lifespan, winter in Swanzey will find that weakness.
Most torsion springs are rated for approximately 10,000 cycles. one cycle being a single open-and-close. If you're using your garage door twice a day, that works out to roughly 7,10 years of life. If your home was built between 1970 and 1999. which covers a large portion of the housing stock in West Swanzey and East Swanzey. and the springs have never been replaced, the math may not be in your favor.

Springs rarely fail without giving some advance notice. Here's what to look for before you end up with a door that won't open:
- The door feels unusually heavy when you lift it manually - Popping, creaking, or rattling sounds during operation. especially on cold mornings - Jerky or uneven movement as the door opens or closes - The door opens only partway and then stops - One side of the door sags or the door looks crooked. a sign one spring is carrying more load than the other - A visible gap in the spring coil. if you can see a separation in the coil above the door, that spring is already broken
If you hear a sudden loud bang from your garage. even if you weren't using the door at the time. that's almost certainly a spring snapping. At that point, stop using the door. A typical residential garage door can weigh 200 to 300 pounds, and without functioning springs, that weight becomes genuinely dangerous. Learn more about what to do in that situation in our guide on manual release safety.
There are a few things you can do yourself to reduce spring stress during cold months:
Lubricate the springs before winter. Apply a silicone-based lubricant. not WD-40. to the springs, cables, rollers, and hinges in the fall. Unlike standard grease, silicone-based lubricants won't thicken and turn sticky in cold temperatures. This reduces friction on every cycle and slows the rate of wear.
Test your door's balance. Disconnect the opener and manually lift the door halfway. A properly balanced door should stay in place without support. If it drops or rises on its own, the springs are either worn or out of adjustment. and that's a job for a technician.
Don't force a door that feels wrong. If the opener is straining or humming louder than usual, or the door jerks as it opens, stop using it until someone takes a look. Forcing it accelerates wear and increases the chance of a sudden failure.
Spring repair and replacement should always be handled by a professional. The tension stored in a garage door spring is enormous, and improper handling can cause serious injury. That's not a disclaimer. it's a practical reality that even experienced DIYers get wrong. If you're seeing warning signs, contact our team before the situation turns into an emergency call.
If one spring breaks, it's worth discussing replacing both at the same time. especially if the system is 7 or more years old. The second spring has experienced the same wear cycles as the first, and a second failure often follows within weeks or months. Replacing both at once saves on labor and eliminates the second service call.
Homeowners in Keene and throughout the Cheshire County area deal with the same spring issues that Swanzey residents face. The common thread is the winter temperature range here. it's simply hard on steel components that are already under tension.

Q: Can I still use my garage door if I think a spring is broken? A: No. If you suspect a spring has broken. especially if you heard a loud bang or the door feels extremely heavy. stop using the opener immediately. Operating the door without a functioning spring puts excessive strain on the opener motor and creates a safety hazard. Call a technician before using the door again.
Q: How do I know if I have torsion springs or extension springs? A: Torsion springs are mounted horizontally above the door opening along a metal rod. Extension springs run along the horizontal tracks on either side of the door and stretch when the door closes. Both can fail in cold weather, but torsion springs are more common in homes built after the 1990s.
Q: Is it normal for my garage door to be harder to open on cold mornings? A: Some extra resistance on very cold mornings is normal due to metal contraction and lubricant thickening. But if it's noticeably harder than usual, or if the opener sounds like it's struggling, that's a sign the springs or lubrication need attention. not something to ignore until spring.
