If you've ever walked out to your garage on a January morning in Bradford and found the door won't budge, there's a decent chance a spring is to blame. It's not bad luck. it's physics. The Merrimack County winters we get here are genuinely punishing on the metal components that hold your garage door system together, and springs bear the worst of it.
Understanding why that happens. and what to do before it catches you off guard. is worth a few minutes of your time.
Bradford sits in central New Hampshire, about 28 miles from Concord, where winters are long and legitimately cold. Historically, the area sees lows around 21°F, but hard cold snaps regularly push temperatures well below zero. That kind of sustained cold is the enemy of torsion springs and extension springs alike.
Here's the core problem: metal contracts in cold temperatures. When your springs are already under substantial tension from counterbalancing your door's weight. sometimes 150,200 lbs for a standard insulated door. that metal contraction adds stress on top of stress. Every single open-and-close cycle in cold weather accelerates metal fatigue. Springs that might last 10,000 cycles in a moderate climate can fail noticeably sooner in a place like Bradford.
But it's not just the cold that gets you. It's the freeze-thaw cycle. Bradford winters don't stay uniformly cold. temperatures swing dramatically, sometimes 30 or 40 degrees in a single day. Metal expands and contracts repeatedly with those swings, and over months and years, that cycle quietly weakens the coil structure from the inside out.
The old farmhouses, Cape Cods, and colonial-style homes common throughout Bradford and nearby Henniker often have attached garages, meaning the door gets used multiple times a day, every day. High usage combined with cold stress is a reliable recipe for spring failure.
Don't wait for a complete failure. that's when you're late for work and the door is stuck at floor level. Watch for these warning signs:
- The door feels heavier than usual. If your opener is straining or the door moves sluggishly with manual operation, spring tension is dropping. - Visible gaps or separation in the coil. A broken torsion spring will show a visible gap in the coil above the door. Don't ignore it. - Loud bang from the garage. One of the most common calls we get at Garage Door Bradford. homeowners who heard a loud bang from the garage and found nothing obvious. That bang is often a torsion spring snapping under load. - The door opens unevenly. If one side of your door rises higher than the other, an extension spring on one side may be weakening or has already failed. - The opener runs but the door barely moves. Most openers will disengage rather than fight a broken spring. The motor runs, but the door stays put.
Torsion springs mount horizontally above the door opening on a metal shaft. They're the standard on most modern doors and are generally safer when they break because the coil stays on the shaft. Extension springs run along the upper horizontal tracks on each side of the door and stretch as the door closes. Older homes in Bradford. particularly those with smaller single-car garages. are more likely to have extension springs.
Both types can and do fail in winter. If you're not sure which type you have, check our services page. we inspect both types and can tell you the condition of your springs during any service visit.

Let's be direct: spring replacement is not a DIY job for most homeowners. Torsion springs are under several hundred pounds of torque. When they release unexpectedly, they can cause serious injury. This isn't a scare tactic. it's the reason most professional garage door technicians consider spring work one of the most hazardous tasks in the trade.
That said, there are things you *can* do yourself:
- Lubricate your springs twice a year. fall and spring. with a lithium-based spray or dedicated garage door lubricant. This reduces friction and slows wear. Do not use WD-40; it strips the lubricant that's already there. - Test spring balance manually. Disconnect your opener, lift the door by hand to waist height, and let go. A properly balanced door should stay put. If it drops or shoots upward, your spring tension is off. - Inspect visually each season. Look for rust, gaps in the coil, or visible wear. Catching early signs gives you time to schedule service before failure.
A professional spring replacement in the Bradford area typically runs $150,$300 for most standard residential doors, depending on spring type, size, and whether you're replacing one or both. For torsion spring setups, replacing both springs at the same time is almost always worth it. if one has failed, the other is near the end of its life too.
Turnaround is fast. Most spring replacements can be completed in under an hour by an experienced technician. If you're dealing with a failed spring right now, contact us directly and we can usually get to Bradford and the surrounding Contoocook and Hopkinton areas the same day or next day.
- Lubricate every fall before the cold sets in. This is the single highest-impact maintenance step you can take. - Don't force a heavy door. If the door feels hard to open manually, stop and call a pro. Forcing it stresses the springs further. - Consider upgrading to high-cycle springs. Standard springs are rated for 10,000 cycles. High-cycle versions. rated for 20,000,50,000 cycles. cost more upfront but make a lot of sense for busy households in demanding climates. - Keep the garage reasonably warm. Even a modest amount of heat retention in the garage reduces the severity of temperature swings on your hardware. Our insulated garage doors guide explains how the right door can help with exactly this.
Q: How do I know if my garage door spring is broken versus just needing adjustment? A: A broken torsion spring usually shows a visible gap in the coil above the door and often causes the door to be completely inoperable or extremely heavy. A spring that needs adjustment may allow the door to move but unevenly or with more effort than usual. Either way, both issues should be addressed by a professional.
Q: Can I still use my garage door if a spring is broken? A: Technically, some openers will still attempt to operate with a broken spring, but doing so can damage your opener motor and the door itself. It's best to stop using the door and call for service as soon as possible.
Q: How often should garage door springs be replaced in Bradford's climate? A: Standard springs typically last 7,10 years in normal use. In Bradford's cold climate with significant seasonal cycling, inspect them annually and don't push past obvious wear signs. High-cycle spring upgrades are worth considering if you're replacing springs for the second time.
