If you've ever walked into your garage on a cold Chester morning, hit the button, and heard nothing but a loud bang followed by a door that won't budge. you've probably just experienced a broken torsion spring. It's one of the most common calls we get here at Garage Door Chester, and it almost always follows the same seasonal pattern: late winter, right when everyone thinks the worst of the cold is over.
There's a real mechanical reason for this, and understanding it can save you from getting stuck inside your garage on a workday.
Chester sits in Rockingham County at around 700 feet of elevation, and the winters here are no joke. Temperatures regularly swing from the single digits overnight to the mid-30s by afternoon. That kind of daily freeze-thaw cycling is exactly what destroys garage door springs over time.
Here's the physics of it: torsion springs are made of coiled steel, and steel contracts when it gets cold. Each time temperatures drop and rise, the metal expands and contracts slightly. Those microscopic stress cycles accumulate over an entire winter season. by late February or March, springs that were already worn from years of use reach a breaking point. It's not any single cold snap that does it. It's the cumulative damage from months of temperature swings.
This is especially true in Chester and the surrounding towns of Derry and Londonderry, where late winter is notorious for those sharp morning frosts followed by afternoon thaws. The spring hasn't been getting weaker from one event. it's been quietly failing since November.
Most torsion springs are rated for about 10,000 cycles, with one cycle being a single open-and-close of the door. If your household uses the garage twice a day, that works out to roughly 7,10 years of life. If you've lived in your Chester home for more than seven years and never replaced the springs, they're likely living on borrowed time. especially heading into or out of a New Hampshire winter.
For homeowners in the newer Colonial-style homes along Chester's residential roads, where the attached garage is often the primary entry point to the house, a spring failure isn't just an inconvenience. It can trap your car inside and leave your home exposed if the door fails in the open position.
Don't wait for the loud bang. Springs usually give off warning signs before they fail completely:
- The door feels heavier than usual. especially on cold mornings. Fatigued springs lose tension capacity as temperatures drop and can't counterbalance the door's weight as efficiently. - Uneven movement. if one side of the door appears to sag or the door jerks while opening, a spring on that side is likely weakening. - Unusual sounds. creaking, popping, or squeaking during operation are signs of metal stress. Don't ignore them. - The opener struggles. when springs lose strength, the opener works harder to compensate. You might notice it humming longer or reversing unexpectedly. - Visible gaps in the coil. take a flashlight and look at the spring mounted above your door. If you see a gap in the coils where they've separated, that spring is broken.

If your spring is broken, stop using the door. Continuing to operate a door with a failed spring puts enormous strain on the opener motor and can damage cables, drums, and other hardware. turning a one-part repair into a much bigger job.
Spring replacement is not a DIY project. A typical residential garage door weighs 200 to 300 pounds, and torsion springs are under enormous tension even when the door is closed. Improper handling can cause serious injury. This is a job for a professional every time.
What you *can* do yourself is lubricate your springs before problems develop. A light coat of silicone-based lubricant on the coils. applied once in fall and once mid-winter. helps reduce rust, keeps the metal moving smoothly, and slightly reduces the stress of temperature cycling. Avoid WD-40; it's not a proper lubricant for garage door hardware and can attract grime.
For a broader pre-winter checklist, our post on winter preparation for your garage door covers lubrication, weatherstripping, and more.
Here's the honest truth about timing: scheduling a planned spring replacement before failure is significantly less expensive than an emergency call after the spring snaps. Emergency service always costs more, and if the failure happens on a Saturday morning when your car is stuck inside, you may be waiting longer than you'd like.
If your springs are approaching 7,10 years old, ask a technician to inspect them when you schedule your next service visit. In many cases, replacing both springs at once. even if only one has failed. makes practical sense, since the second spring is likely near the end of its cycle life anyway.
The full range of services we offer at Garage Door Chester includes spring inspection, replacement, and a complete hardware check to make sure nothing else is showing signs of wear.
Q: My garage door opened fine last night but won't move this morning. What happened? A: This is a classic spring failure scenario, especially in cold weather. The steel becomes more brittle overnight as temperatures drop, and a spring that was marginal the night before can snap by morning. Disconnect the opener and try lifting the door manually. if it feels extremely heavy or won't lift at all, a broken spring is the likely culprit. Don't keep pressing the opener button.
Q: Can I still use the garage door with a broken spring? A: You shouldn't. Without a functioning spring to counterbalance the door's weight, the opener motor is under severe strain and can burn out or strip its gears. The door can also drop suddenly, creating a safety hazard. Leave it closed and call a professional.
Q: How do I know if I have torsion springs or extension springs? A: Torsion springs are mounted horizontally above the door on a metal rod and look like a thick coil. Extension springs run along the horizontal tracks on either side of the door and stretch as the door closes. Most newer homes in Chester with standard attached garages use torsion springs, but older homes may have the extension type. Both can fail in cold weather. the repair approach differs depending on which system you have.
