If you've ever walked into your garage on a January morning, hit the button, and heard nothing but a loud bang followed by silence. you already know what a broken torsion spring feels like. It's one of the most common calls we get from homeowners in Seabrook, Hampton, and throughout the NH Seacoast between December and March, and there's a good reason for that.
<--seabrook-climate-context--> Seabrook sits in a humid continental climate where winters are genuinely freezing. temperatures regularly drop to 20°F or below, with high humidity year-round due to the town's proximity to the Atlantic Ocean. That combination does something specific and damaging to garage door springs.
Torsion springs are made of tightly wound steel. When temperatures fall below freezing, that steel contracts and becomes more brittle, making it significantly more susceptible to snapping under the tension it holds every time you open and close your door. This isn't a design flaw. it's physics. But here's what makes Seabrook particularly tough on springs: it's not just the cold that does the damage. It's the repeated freeze-thaw cycling that accumulates over a whole season.
Each time the temperature swings from the mid-30s down to the teens and back up again. something that happens dozens of times between November and March on the New Hampshire seacoast. the metal in your spring expands and contracts slightly. Over months, that micro-stress builds up, and by late February, springs that were already aging are often at their breaking point. It's no coincidence that the busiest stretch of emergency spring calls tends to fall right at the tail end of winter.
Garage door springs rarely fail with zero warning. Here's what to look and listen for:
Disconnect your opener and manually lift the door to about waist height. Let go. A properly balanced door should stay in place. If it drops immediately or feels like you're lifting dead weight, your springs have likely lost significant tension and are no longer doing their job of counterbalancing the door's weight. A standard residential garage door can weigh 150,300 pounds. the springs are what make it feel light.
If your door tilts to one side as it opens, or stutters and jerks instead of moving smoothly, that's a classic sign that one spring is weaker than the other. When springs wear at different rates, the door becomes unbalanced. Left unaddressed, this strains your opener motor and puts extra wear on your tracks and rollers. turning a spring repair into a much larger job. Check our garage door feature checklist to understand how all the components work together as a system.
Loud creaking or popping sounds during operation indicate metal stress building in the spring coil. A sudden, sharp bang. especially one you hear from inside the house. often means the spring has already snapped. If that happens, stop using the door immediately. Do not use the opener. The opener is not designed to lift the full weight of an unassisted door and will burn out the motor quickly if you keep running it.
Look at your torsion spring (the horizontal coil mounted above the door on a metal shaft). If you can see a gap of roughly two inches or more in the coil, the spring has broken. This is a clear, visual confirmation that the spring needs professional replacement before you use the door again.
We understand the impulse to handle things yourself. especially for homeowners who are handy. But garage door spring replacement is genuinely dangerous, and that's not an exaggeration made to drum up business. Torsion springs store massive amounts of kinetic energy. When the winding cones are manipulated incorrectly, that energy releases instantly and can cause severe injury. Beyond the safety risk, the spring must be precisely calibrated to your door's specific weight and dimensions. An incorrectly sized spring will either cause the door to fly open uncontrolled or put so much strain on the opener motor that it burns out within weeks. You can read more about how your opener and springs work together on our services page.
If your springs are approaching 7,10 years old, or if you're using the garage door four or more times a day, it's worth having them inspected now rather than waiting for an emergency failure on a cold February morning.
- Visually inspect your springs monthly from a safe distance. Look for rust spots, gaps between coils, or any stretching or sagging. - Lubricate the springs with a silicone-based spray every three months. Avoid WD-40. it attracts dirt and doesn't protect metal long-term. - Test door balance by disconnecting the opener and lifting the door halfway manually. It should hold its position without drifting. - Schedule a professional inspection if your springs are more than five years old or if you notice any of the warning signs above.
If you're already seeing signs of trouble, don't wait for the spring to snap. contact us to schedule an inspection before it becomes an emergency call on the coldest morning of the year.
Q: How long do garage door springs typically last in Seabrook? A: A standard torsion spring is rated for approximately 10,000 cycles. one cycle being a full open and close. For a household using the door 3,4 times per day, that's roughly 7,10 years. However, Seabrook's coastal humidity and freeze-thaw winters can accelerate wear, so springs in beachside neighborhoods like Seabrook Beach may age faster than that estimate.
Q: Can I still use my garage door if one spring is broken? A: You should not. With a broken spring, the opener is lifting the full dead weight of the door on its own, which it isn't designed to do. Continued use can burn out the motor, snap the lifting cables, or cause the door to come down unexpectedly. Keep the door in the closed position and call for service.
Q: Should I replace both springs at the same time even if only one broke? A: Yes, almost always. Both springs were installed at the same time and have the same number of cycles on them. If one has failed, the other is likely close behind. Replacing both at once saves you a second service call. and the cost of being caught off guard by the next failure.
