If you've ever walked into your garage on a frigid Sharon morning and found the door completely unresponsive. or heard a loud bang from the garage overnight. there's a good chance a spring gave out. It's one of the most common calls we get every winter, and it's not random bad luck. The physics of cold weather and steel make it almost predictable.
Sharon sits in the Monadnock Region of southern New Hampshire, and the winters here are no joke. Temperatures regularly drop into the single digits and below zero, with lows that can hit the teens below freezing on especially brutal stretches. That kind of sustained cold puts real mechanical stress on the steel components of your garage door. especially the springs.
Torsion springs (the horizontal coil mounted above the door) and extension springs (running along the sides) are both made of high-strength steel under constant tension. When the temperature drops, that steel contracts and becomes less flexible. The spring doesn't get weaker all at once. it's a gradual process where each cold snap, each freeze-thaw cycle, adds a little more stress to metal that's already working hard every single time the door moves.
Most standard torsion springs are rated for around 10,000 cycles. one cycle being one open and one close. If your garage door sees regular daily use, that lifespan works out to roughly 7,10 years. A spring that's already logged thousands of cycles going into a Sharon winter is running out of runway fast.
Here's the frustrating part: a spring that functioned just fine all summer can reach its breaking point when the temperature drops. Cold temperatures don't cause failure by themselves, but they accelerate wear in metal that's already fatigued, pushing it past the point of no return.
Springs rarely fail completely without some advance notice. If you pay attention, you'll usually see. or hear. the trouble coming:
- The door feels heavier than usual, especially on cold mornings. This means the spring is losing its ability to counterbalance the door's weight. - Jerky or uneven movement when opening. If the door stutters, stops mid-way, or one side rises faster than the other, a spring is struggling. - Unusual sounds. popping, creaking, or a grinding noise during operation. all signal metal stress. - A visible gap in the spring coil. Stand inside your garage and look at the torsion spring above the door. A separation in the coil is a definitive sign it has snapped. - A sudden loud bang from the garage, even when you weren't using the door. That's the sound of a spring letting go under tension.
If you notice any of these, stop using the door manually. A broken spring means the door's full weight. which can be 200 pounds or more for a standard residential door. is no longer supported. Forcing it open risks damaging the opener and, more importantly, injuring someone.
This is worth being direct about: garage door spring replacement is not a safe DIY project, and it's not a matter of skill level. Springs store an enormous amount of mechanical energy under tension. If one snaps or uncoils while you're working on it without the proper tools and training, the force can cause severe injury. Every year, homeowners are hurt attempting this repair. It's one of those jobs where calling a professional isn't just a suggestion. it's the right call. Check out our full list of services to understand what a proper spring inspection and replacement involves.
While spring replacement is pro territory, there are things you can do as a homeowner to slow down the wear:
Lubricate every fall. Before Sharon's temperatures bottom out, apply a lithium-based or silicone garage door lubricant directly to the spring coils. Avoid WD-40. it's a solvent, not a lubricant, and it can actually make things worse in cold weather by gumming up.
Keep the garage temperature above freezing if possible. Even a few degrees can meaningfully reduce the stress on metal components. If your garage is attached to the house, check the weatherstripping around the door and any wall insulation to help retain heat.
Don't ignore a slow door. If your opener is straining harder than usual in January, that's a signal. The opener working overtime because the springs are weakening puts stress on multiple components at once.
Count the years. If you've lived in your home for 7 or more years and never replaced the springs, they're likely approaching the end of their rated cycle count. Proactive replacement on your schedule is far less disruptive than an emergency call at 7 a.m. when you need to get to work in Peterborough.

If your door won't open, feels dramatically heavier than usual, or you've heard that telltale bang, call Sharon Garage Doors right away. Operating a garage door with a broken or failing spring risks damaging the opener motor, bending the tracks, and creating a genuine safety hazard. The sooner it's addressed, the simpler and less expensive the fix. Reach out to schedule a service call. we serve Sharon and the surrounding towns including Jaffrey, Hancock, and Antrim.
A broken spring will usually result in a door that won't open at all, hangs crooked, or feels extremely heavy. You may also see a visible gap in the coil above the door. A door that moves but squeaks or feels sluggish is more likely a lubrication issue.
No. you should stop using it immediately. With a broken spring, the full unassisted weight of the door is transferred to the opener and cables, which can cause additional damage and create a serious safety risk.
For a professional technician, replacing a standard residential torsion spring typically takes one to two hours. Having both springs replaced at the same time is usually recommended, since if one has failed, the other is likely near the end of its life as well.
