Why Garage Door Springs Break in Tewksbury Winters (And What To Do About It)
2026-03-30 7 min read
If you've ever walked into your garage on a cold Tewksbury morning and found the door completely dead. opener humming, door not budging. there's a good chance a torsion spring let go overnight. It happens dozens of times every winter across Middlesex County, and it's not bad luck. There's real physics behind why springs fail during New England winters, and knowing the signs can save you from being stranded.
What Tewksbury's Climate Does to Garage Door Springs
Tewksbury winters are genuinely brutal. Temperatures regularly drop into the teens overnight, and January averages a high of just 32°F with lows around 20°F. But it's not the extreme cold alone that kills springs. it's the constant cycling between cold and warm. A morning that starts at 15°F can climb to the upper 30s by afternoon, then drop back down after dark. That daily expansion and contraction of metal is relentless.
Garage door torsion springs are made from hardened steel wire under constant tension. Every open-and-close cycle twists and untwists the coil, and cold temperatures make that steel more brittle through a process called ductile-to-brittle transition. which in steel can begin around the freezing point. Add months of accumulated micro-damage from temperature swings, and by late February or early March the spring is running on borrowed time. That's exactly when our phones start ringing.
Neighborhoods like Evergreen Estates and Blacksmith Village are full of colonial-style homes built in the late 1970s. which means attached garages with original or once-replaced springs that may be well past their service life. If your home was built around that era and you've never thought about your springs, now is a good time to start.
Warning Signs to Watch For
Springs rarely fail without giving you a few hints first. Here's what to pay attention to:
- A visible gap in the torsion spring. look at the bar mounted above the door. A separation in the coil is a clear break. - The door feels unusually heavy. if you disconnect the opener and try to lift manually, a door in good working order should stay put at waist height. If it crashes down, the spring isn't doing its job. - Jerky or uneven movement. one side rising faster than the other suggests a spring is losing tension or has already failed on one side. - Loud popping or banging sounds. a spring snapping sounds like a gunshot inside the garage. If you hear it, don't try to operate the door. - The opener strains or reverses. when a spring is weak, the opener motor takes on the full weight of the door and will either stall or trigger the safety reversal.
If you notice any of these, stop using the door and contact us to schedule an inspection before the situation gets worse.
Torsion Springs vs. Extension Springs: Does It Matter?
Most homes in Tewksbury with sectional garage doors use torsion springs. the horizontal coil mounted above the door on a metal shaft. Older homes, or doors with lower headroom, may have extension springs on each side that stretch as the door closes.
Both types fail in cold weather, but torsion springs are generally more predictable in their failure and safer to replace because the energy is contained on the shaft. Extension springs can whip when they snap if they're not properly contained with a safety cable running through the coil. If your extension springs don't have those cables, that's worth addressing regardless of their age.
Should You Replace One Spring or Both?
This is one of the most common questions we get. If you have a two-spring system and one breaks, it's almost always worth replacing both at the same time. The surviving spring has the same number of cycles on it as the broken one. meaning it's equally worn. Replacing just one sets you up for another failure within months, often at an inconvenient time. You'll pay a second service call and a second labor charge. Do both springs together and you reset the clock on the whole system.
When replacing, ask about high-cycle springs rated for 20,000 to 30,000 cycles. Standard builder-grade springs often come rated for 10,000 cycles or fewer. For a family using their garage door four times a day, a 10,000-cycle spring lasts roughly seven years under ideal conditions. less in a climate like ours. Upgrading to high-cycle springs at replacement time is one of the better investments you can make in a garage door system.

Why DIY Spring Replacement Is a Hard No
Torsion springs store enormous amounts of energy under tension. enough to cause serious injury or worse if they release unexpectedly during removal. This isn't a scare tactic; it's the single repair on a garage door that even experienced DIYers should leave alone. The job requires specialized winding bars, knowledge of the correct torque for your specific door weight, and the experience to handle a component that can snap with life-threatening force.
For everything else. lubrication, sensor alignment, bottom seal replacement. a confident homeowner with the right information can handle plenty on their own. Springs are the exception. Our services page gives a full picture of what professional repairs look like if you're curious about the process.
Proactive Steps Before Next Winter
The best time to deal with springs is before they fail, not after. A few things you can do right now:
1. Lubricate your springs every fall. use a silicone-based spray or white lithium grease. Avoid standard WD-40, which attracts grit and breaks down quickly in cold temperatures. 2. Do the balance test. disconnect the opener, lift the door to waist height manually, and let go. It should stay put. If it drifts up or crashes down, the springs are out of balance. 3. Look for surface rust. corrosion weakens springs faster. A coat of lubricant helps, but heavily rusted springs should be replaced regardless of their cycle count. 4. Know the age of your springs. if you moved into a home and don't know when they were last changed, assume they may be original. A quick inspection call is worth it.
Homeowners across Lowell and Billerica deal with the same winter stress on their garage door systems. But getting ahead of it before the first hard freeze of the year makes all the difference.
Frequently Asked Questions
Q: My garage door opener runs but the door won't move. is it definitely a broken spring? A: That's the most common symptom of a broken torsion spring. The motor is doing its job, but without the spring counterbalancing the door's weight, the opener can't lift it. Look above the door for a visible gap in the spring coil. Don't keep running the opener. doing so can burn out the motor.
Q: How long does a spring replacement typically take? A: For a professional technician with the right tools, replacing a single or double torsion spring typically takes 45 minutes to an hour. Having both springs replaced at once adds minimal time to the job.
Q: Can I still manually open my garage door if a spring breaks? A: Technically yes, but a standard sectional garage door weighs 150,200 pounds or more. Without functioning springs to counterbalance it, manually lifting the door is extremely difficult and can injure your back. It's better to use a side entry door until repairs are made.
