Why Thompson Garage Door Springs Break in Winter (And What to Do About It)
2026-04-16 7 min read
If you've ever walked into your garage on a frigid January morning only to find the door won't budge, there's a good chance a broken spring is to blame. It's one of the most common calls we get here in Thompson, CT. and it's not a coincidence that it tends to happen in the dead of winter.
Thompson sits in Connecticut's Quiet Corner, one of the colder inland pockets of the state. Unlike the coast, we don't get the moderating effect of Long Island Sound. Winters here regularly drop below freezing, with temperatures sometimes falling into the teens and even single digits, and snowfall averaging around 40 inches per year. That kind of cold puts real stress on your garage door's mechanical components. especially the springs.
Why Cold Weather Is So Hard on Garage Door Springs
Garage door springs are under enormous tension at all times. They counterbalance the weight of your door, making it possible for a relatively small motor (or your own arm) to lift something that might weigh 150,400 pounds. In warmer months, the metal is flexible and the tension is manageable. But in winter, things change fast.
Metal contracts in cold temperatures. When steel gets cold, it loses some of its flexibility and becomes more brittle. A spring that's already been cycling thousands of times over its lifespan is far more likely to snap when it's stiff from the cold. Add in the freeze-thaw cycles that Thompson homeowners know well. temperatures dropping overnight and then warming back up during the day. and the metal fatigue compounds quickly.
Lubricants also thicken or freeze in low temperatures, which means the spring has to work harder with less protection. It's a bad combination.
Torsion Springs vs. Extension Springs
Most Thompson homes. whether you're in a ranch on a quiet road off Route 193, a split-level near the Quaddick Reservoir area, or a colonial closer to the Woodstock or Putnam border. use one of two spring types:
- Torsion springs sit horizontally above the door and twist to store energy. They're more common on heavier two-car doors and tend to last longer. - Extension springs run along the sides of the door tracks and stretch when the door closes. They're lighter-duty and more common on single-car doors.
Both types are vulnerable to cold-weather failure, but extension springs tend to go first because they're exposed to more movement and stress across their full length.
Warning Signs Your Springs Are About to Fail
Springs rarely snap with zero warning. Here's what to watch for, especially as temperatures drop in November and stay low through March:
- The door feels heavier than usual. If you disconnect the opener and manually lift the door, it should move smoothly with little effort. If it feels like you're lifting the door yourself, the springs may be losing tension. - A loud bang from the garage. A snapping spring sounds like a gunshot inside the garage. Many homeowners first hear it in the middle of the night when temperatures drop sharply. - Visible gaps in the torsion spring. Take a look at the spring above your door. A gap in the coil is a clear sign it's broken. - The door opens unevenly or tilts to one side. If only one spring has failed on a two-spring system, the door may still move but will lift crookedly. - The opener strains or reverses. Your opener is designed to stop if it detects too much resistance. A broken spring means the opener is suddenly trying to lift the full weight of the door. it may strain, stall, or reverse as a safety measure.

What to Do When a Spring Breaks
First: don't try to operate the door. Forcing the opener to run with a broken spring can burn out the motor or damage the opener's drive system. turning a $200 spring repair into a $600+ problem.
If the door is closed and you need to get your car out, you can manually open it using the red emergency release cord. but be warned, the door will be very heavy without the spring's counterbalance. Have another person help you, and prop it open securely before going underneath it.
Then call a professional. Garage door spring replacement is one of those jobs that genuinely isn't DIY-friendly. Springs are under extreme tension and can cause serious injury if released improperly. Even experienced homeowners can miscalculate the winding process. This is a job for a trained technician with the right tools.
Thompson Garage Doors handles spring replacements throughout Thompson and the surrounding area, including Putnam, Killingly, and Woodstock. We typically recommend replacing both springs at the same time. if one has failed, the other is usually close behind, and the labor cost to do them together is far less than two separate service calls.

Preventing Spring Failures Before They Happen
You can't make springs last forever, but you can extend their life significantly with a little attention:
1. Lubricate your springs every fall. Use a lithium-based or garage door-specific lubricant. not WD-40, which evaporates quickly. Coat the coils lightly and wipe off any excess. This is especially important before Thompson's first hard freeze. 2. Check the door balance twice a year. Disconnect your opener and lift the door manually to the halfway point. If it stays in place, the springs are balanced. If it falls or rises on its own, the tension needs adjustment. 3. Don't ignore small issues. Squealing, grinding, or uneven movement are early warning signs. Catching a problem in October is much better than dealing with a broken spring on a 10-degree morning in January.

How Long Do Garage Door Springs Last?
Most residential garage door springs are rated for about 10,000 cycles. One cycle is one open and one close. For a family that uses the garage door four times a day, that's roughly 7 years of use. Heavy-use households may see springs fail sooner; lighter-use homes may get 10,12 years.
If your Thompson home was built in the early 2000s or before and you haven't had your springs replaced, it's worth having them inspected. especially before winter.

Frequently Asked Questions
Can I still use my garage door with a broken spring?
Technically, some doors will still move with a broken spring, but you should not use the opener or go under the door. The door is extremely heavy without the spring's counterbalance, and forcing the opener can cause additional damage. Call for service before operating the door again.
How much does a spring replacement cost in Thompson, CT?
Most residential torsion spring replacements run between $150 and $350 for a single spring, or $200,$450 for both springs replaced at the same time. The exact cost depends on the spring size, door weight, and whether any additional hardware needs attention. Get a specific quote from our services page.
Why did my spring break in the middle of the night?
Springs most often fail when they're under full tension. meaning when the door is closed. Temperatures also drop to their lowest point overnight, which makes cold-stressed metal more likely to snap. The combination of full tension and frigid temps is when failures most commonly occur.
