If you've lived in Campton long enough, you know the pattern: January drops overnight lows near 9°F, February stays stubbornly frozen, and then March starts playing tricks. warm one afternoon, back below freezing the next morning. That temperature cycling is exactly what destroys garage door springs, and it happens here more aggressively than almost anywhere else in New Hampshire.
Campton sits in the foothills of the White Mountains, which means the weather isn't just cold. it's variable. That freeze-thaw pattern through late winter is the real culprit behind most of the spring failures we see, whether you're in Campton Hollow, West Campton, or just off Route 49 heading toward Waterville Valley.
Garage door springs are made of tightly wound high-strength steel. Steel contracts when temperatures drop, which means the coils tighten. adding tension to a component that's already under significant load every time the door cycles. As the metal contracts, the spring becomes more brittle and less flexible, making it more susceptible to breaking under that added tension.
But the real damage doesn't come from a single cold night. Each temperature swing forces the metal to expand and contract slightly, and by late winter, months of accumulated micro-damage reach a critical threshold. The spring hasn't grown weaker from one cold snap. it's been weakening incrementally with every freeze-thaw cycle since November.
On top of that, cold weather stiffens every other component. rollers, hinges, and weatherstripping. making the door heavier and harder to lift. That added resistance transfers directly to the springs, forcing them to work harder with each cycle. If your springs are already a few years old, that's often the final push they can't handle.

Springs rarely fail without some warning. Here's what to watch for, especially heading through late winter:
- The door feels heavier than usual. Disconnect the opener using the manual release cord and try lifting the door by hand. A properly balanced door should hold itself up at the halfway point. If it falls or feels like you're lifting dead weight, your springs are losing tension. - Loud creaking or groaning during operation. This indicates metal stress and friction that wasn't there before. - Slow or jerky movement. If the door hesitates, stutters, or moves unevenly, that's a sign one spring is working harder than the other. or one has already partially failed. - A sudden loud bang from the garage. This is usually a spring snapping. You'll often hear it even if you're inside the house. The door will then feel nearly impossible to lift.
If any of these signs appear, stop using the automatic opener immediately. Running a door with a broken or severely weakened spring puts enormous strain on your opener motor and risks damaging the entire system. or worse, causing the door to fall unexpectedly.
Torsion springs mount horizontally above the door opening and are the most common setup in homes built in Campton and nearby Plymouth over the past 25 years. They wind and unwind as the door operates and are generally more durable and balanced than the older extension-spring design.
Extension springs run along the horizontal tracks on each side of the door and are more common on older homes and cabins in areas like Campton Hollow or lower-elevation properties closer to the Pemigewasset River. Both types are under extreme tension and must never be adjusted or replaced by anyone other than a trained technician.
Most torsion springs are rated for roughly 10,000 cycles. one open and one close equals one cycle. For a household that uses the garage twice a day, that's about 13,14 years. If your door is approaching that age, proactive replacement before next winter is a smart investment.
You can't prevent physics, but you can reduce the risk:
1. Lubricate the springs every fall. Use a silicone-based spray or lithium grease. never WD-40 or standard oil, which thickens in freezing temperatures and increases friction. A light coat on the coils reduces rust and keeps the metal slightly more flexible through the cold season. 2. Test the door balance in fall, not February. Disconnect the opener and lift the door to waist height. It should stay put. Do this check before the deep freeze sets in so you have time to schedule service without urgency. 3. Keep the garage even a few degrees above freezing. Insulating your garage door. particularly if it's an older uninsulated model common in Campton's vacation-home communities. and sealing gaps helps maintain metal flexibility. See our post on essential winter prep tips for more detail on this. 4. Don't ignore age. If your springs are seven years old or more and you haven't had them inspected, schedule a checkup before next winter.
Spring replacement is not a DIY job. full stop. Both torsion and extension springs are under immense pressure, and a spring that snaps while someone is working on it can cause severe injury or significant property damage. The tools required are specialized, and the safety risk is real.
Garage Door Campton handles spring inspections, replacements, and full tune-ups throughout the Campton area and surrounding towns including Holderness, Ashland, and New Hampton. If your door has been feeling off this winter, don't wait until it fails completely. You can schedule a service visit before the next freeze-thaw cycle does its worst.
A broken spring is usually obvious. you'll hear a loud bang, and the door will feel extremely heavy or won't open at all. A worn spring is subtler: the door feels heavier than it used to, moves unevenly, or the opener strains more than normal. Both situations warrant a professional inspection.
No. Using your opener with a broken spring puts enormous stress on the motor and cables. In the best case, it shortens the life of your opener. In the worst case, the door can fall or the cable can snap. Disconnect the opener and call for service right away.
For most residential doors in Campton, a spring replacement takes roughly one to two hours for a professional technician. Both springs are typically replaced at the same time even if only one has failed. since they age at the same rate, the second one is likely close behind.
