Every winter in New London, the same scenario plays out dozens of times across the city. A homeowner heads to the garage on a cold January morning, presses the opener button, and hears a loud bang followed by a door that won't budge. Nine times out of ten, that sound is a garage door spring snapping. and it almost always happens when temperatures are at their lowest.
New London winters are genuinely cold. January averages a high of around 39°F and a low near 24°F, and the city sees regular freeze-thaw cycles throughout December, January, and February. That pattern of daily temperature swings. cold overnight, slightly warmer by afternoon, cold again by evening. is particularly hard on garage door springs. Understanding why this happens, and knowing the warning signs before a break occurs, can save you from a frustrating and expensive emergency call.
Torsion and extension springs are made of high-strength steel, and steel behaves differently as temperatures drop. When exposed to cold air, the metal contracts, becoming slightly shorter and stiffer. That contraction increases the internal stress within the spring coils. and if a spring is already weakened from years of cycling, the added tension from the cold can push it past its breaking point.
This is what's known as the ductile-to-brittle transition. It doesn't mean perfectly good springs will suddenly fail in cold weather. But springs that are already partway through their service life. typically rated for around 10,000 open-and-close cycles, or roughly 7 to 10 years of daily use. are significantly more vulnerable when temperatures dip below freezing.
New England's freeze-thaw cycle makes this worse. It's not just about extreme cold. it's about the metal expanding and contracting repeatedly throughout the season. Each temperature swing forces the spring to flex slightly, creating cumulative micro-damage in the steel. By late February and into March, many springs that survived December are reaching a critical threshold after months of this stress. That's why spring failures often spike in late winter rather than during the coldest nights.
The daily routine also matters. Shorter winter days mean more trips in and out of the garage in the dark, adding extra cycles at a time when the springs are already under elevated stress from the cold.
Springs rarely fail without giving some advance notice. Knowing what to look and listen for can get you ahead of a failure before it strands you in your driveway on a 25-degree morning.
When springs lose tension capacity as they fatigue, the door feels noticeably heavier to lift manually. If you disconnect your opener and try to lift the door by hand, it should rise smoothly and stay up at about waist height on its own. If it feels heavy or won't hold position, the springs aren't doing their job.
If your door has started taking longer to open than it used to, or if it moves in jerky motions instead of smoothly, that's often a sign the springs are struggling against the cold and the extra resistance from stiffened rollers and hinges. Pay attention to how it behaves on cold mornings specifically. the pattern is often clearest then.
Popping, rattling, or squeaking sounds during operation often emerge before a complete spring failure. A sudden loud bang from the garage. even when the door wasn't being used. is frequently the sound of a spring snapping under tension. If you hear that and then find your door won't open or feels impossibly heavy, stop using it immediately and call for service.
Torsion springs run along a metal shaft above the door opening. If you can safely see the spring and notice a visible gap or separation in the coils, it's broken. Don't attempt to use the door.
If the door appears crooked or one side sags when it opens, that typically indicates one spring is failing or has already broken while the other is still working. This imbalance puts strain on the entire system and needs prompt attention.
For additional context on how your opener and limit settings interact with a struggling spring, our guide on limit switch adjustment is worth a read. sometimes what looks like a limit switch problem is actually a spring balance issue.
This is important: do not continue operating a garage door with a broken spring. Your opener motor is not designed to lift the full weight of the door on its own. Forcing it to do so can burn out the motor or damage the drive mechanism. turning a spring replacement into a much more expensive combined repair. In a worst-case scenario, a door operating without a functioning spring can come down unexpectedly.
If you hear that loud bang and the door won't respond normally, keep it in the closed position and call a professional.
Garage door springs store an enormous amount of energy under constant tension. somewhere between 150 and 200 pounds of force held in the coils at all times. When a spring releases that energy unexpectedly, it can cause serious injury. Broken springs can snap violently across the garage, and improperly installed replacements may fail prematurely or damage other components.
This is one repair that genuinely requires a trained technician with the right tools. If you're researching what's involved before calling, our FAQ page covers spring repair questions and what a professional service visit typically looks like.
The most practical thing you can do is schedule an inspection in the fall, before winter sets in. A technician can identify springs that are nearing the end of their cycle count and replace them on your schedule rather than the spring's schedule. which tends to be 7 AM on a cold Wednesday when you have somewhere to be.
A few other steps help extend spring life through the winter:
- Keep the garage as warm as practical. A warmer garage means less extreme temperature swings for the springs. An insulated garage door helps here. and if you're in one of New London's older Colonial Revival or Cape Cod-style homes, an insulated replacement door can meaningfully improve the thermal performance of the whole garage. - Use a cold-rated synthetic lubricant on rollers, hinges, and moving parts. Standard lubricants can thicken and become sluggish below freezing, creating extra resistance that transfers strain to the springs. Synthetic oils rated to -10°F or lower keep things moving freely. Note: do not lubricate the springs themselves. they're factory-treated, and adding lubricant attracts dirt that accelerates wear. - Replace backup batteries in your opener remote before winter. Cold drains battery efficiency fast, and a weak remote signal is sometimes mistaken for a spring or opener problem.
Homeowners in Ledyard, Montville, and other inland towns near New London see similar spring issues in winter, though without the added coastal corrosion factor. The freeze-thaw cycle is the common thread across the whole region.

Q: My garage door opened fine all fall. Why would a spring break now in late winter? A: It's actually very common for spring failures to happen in late February and March rather than in the coldest weeks of December. The reason is cumulative damage. months of repeated freeze-thaw cycles create microscopic fatigue in the steel. A spring that survived the first cold snaps may finally reach its breaking point after months of continuous stress.
Q: Can I manually open my garage door if the spring is broken? A: Technically yes, but it takes a lot of force because the spring is no longer counterbalancing the door's weight. For most residential doors, that means lifting 100,200 pounds. More importantly, doing so repeatedly without the spring puts stress on the opener and the door panels. It's best to leave it closed until a technician can replace the spring.
Q: How long do garage door springs typically last in New England? A: Most torsion springs are rated for approximately 10,000 open-and-close cycles. roughly 7 to 10 years for a door used multiple times daily. In coastal areas of New London, corrosion from salt air can shorten that lifespan further. If your springs are over seven years old and haven't been inspected recently, it's worth having them evaluated before next winter.
