If you've lived in Deerfield long enough, you already know what a New Hampshire winter can do. Temperatures regularly plunge to single digits, and the swing between a cold morning and an afternoon thaw can be dramatic. sometimes 20 or 30 degrees in a single day. Those freeze-thaw cycles are hard on everything, and your garage door springs are no exception. Every February, calls for emergency spring repairs spike across southern New Hampshire, from Deerfield out to Londonderry and Salem. Understanding why this happens. and what to watch for. can save you a cold-morning breakdown and a costly emergency service call.
Garage door springs are made of tightly wound steel, and steel behaves differently in the cold. When temperatures drop, metal contracts, making the spring shorter and tighter. This means the spring is already under increased tension before you even touch the opener button. When you add the daily load of lifting a door that can weigh 200 pounds or more, you're asking a lot of a component that's become stiffer and more brittle overnight.
The science is straightforward: cold conditions increase tension, reduce flexibility, and accelerate existing wear and tear. A spring that was perfectly functional in October can fail in January. not because it suddenly wore out, but because the cold pushed it past what it could handle. Think of it like bending a metal paperclip back and forth. Each cycle creates microscopic stress. By late winter, months of accumulated expansion and contraction can bring an aging spring to its breaking point.
For Deerfield homes. many of which are older Colonial and Cape Cod-style properties set along country lanes. attached garages are the norm. That means your garage door is likely one of the most-used entry points in the house. If you're opening and closing it three to five times a day, those springs are completing thousands of cycles every year.
Torsion springs. the most common type, mounted horizontally above the door. are typically rated for about 10,000 cycles. At average daily use, that works out to roughly 7 to 10 years. If you bought your Deerfield home and haven't thought about the springs since, it's worth knowing when they were last replaced. Older homes here, including some that date back several decades, may still have original hardware that's well past its service life.
Springs rarely fail without giving some warning. The problem is that homeowners often dismiss those early signals until the door refuses to open on a 5-degree morning. Here's what to pay attention to:
- The door feels heavier than normal when you lift it manually. This is often the first clue that a spring has lost tension or is about to fail. - Unusual noises. pops, squeaks, or rattling during operation. indicate metal stress. - The door jerks or moves unevenly, especially on the way up. If one side is lagging, a spring on that side may be weakening. - A visible gap in the spring coil above the door. This is a broken spring, and it needs professional attention immediately. - A loud bang from the garage, even when you weren't using the door. That's often the sound of a spring snapping under tension.
If any of these sound familiar, don't keep operating the door. Continuing to run a garage door opener against a broken spring can damage the motor and create a safety hazard. Once a spring fails, the door's full weight falls on the opener. a machine that was never designed to carry that load alone.
There are a few things homeowners can safely handle themselves. Applying a silicone-based lubricant to hinges, rollers, and the spring coils in the fall helps reduce friction and slows wear going into the cold months. Keep in mind that standard petroleum-based lubricants can thicken in freezing temperatures, so choose a product rated for cold weather. Also check your weatherstripping. a tight bottom seal helps keep the garage slightly warmer, which in turn keeps metal components more flexible.
For a full breakdown of cold-weather prep tasks, our post on preparing your garage door for cold weather covers the essential steps before the first hard freeze hits.
What you should not do is attempt to replace or adjust torsion springs yourself. Garage door springs store an extreme amount of energy. When that energy releases unexpectedly, it can cause serious injury or property damage. This is strictly a job for a trained technician with the right tools and experience. The risk isn't worth it.
The best time to get your springs checked is in early fall. before the cold sets in and before repair demand spikes in January. A professional inspection at that point lets a technician identify worn springs, lubricate moving parts, and flag anything that won't survive another New Hampshire winter. Scheduling that visit proactively is almost always less expensive than an emergency call on a Saturday morning.
Garage Door Deerfield offers spring inspections and replacements across the area, including customers in Manchester, Chester, and Candia. If your door is showing any of the warning signs above, don't wait for a full failure. Reach out to schedule a visit before it becomes an emergency.

Q: Can I still use my garage door if I think a spring is broken? A: It's best not to. Operating the door with a broken spring puts the full weight of the door on the opener motor, which can burn it out quickly. It also creates a safety risk if the door drops unexpectedly. Disconnect the opener and leave the door closed until a technician can assess it.
Q: How do I know if my Deerfield home has torsion or extension springs? A: Torsion springs are mounted horizontally above the door on a metal shaft. Extension springs run along the horizontal tracks on either side of the door. Torsion springs are more common on heavier doors and newer installations. If you're not sure, a technician can identify them quickly during any service visit.
Q: Should I replace both springs at the same time even if only one broke? A: Yes, in most cases. Both springs age at the same rate since they've been working together since installation. If one has failed, the other is likely close behind. Replacing both at once saves you a second service call. and a second breakdown. in the near future.
