A customer called last Tuesday morning. Her garage door was stuck halfway up. She couldn't get her car out. Within an hour, we found the culprit: a snapped torsion spring on the left side. She'd heard a loud bang the night before but didn't think much of it. That one broken component had made her entire door inoperable. Garage door springs in Glastonbury fail more often than most homeowners realize, and knowing what to watch for can save you from being stranded.
Garage door springs are under enormous tension. A typical residential door weighs 300 to 400 pounds. The spring counterbalances that weight so your opener doesn't have to strain. Over time, metal fatigues. Springs last roughly 7 to 9 years with normal use, roughly 10,000 to 15,000 cycles. That's about four to five cycles per day in an average home. See our guide on 5 warning signs your garage door needs immediate repair.
Two main types exist: torsion springs (wound around a shaft above the door) and extension springs (running along the sides). Torsion springs are more common in newer installations and more durable, but when they fail, they fail suddenly. Extension springs sometimes show warning signs first, like uneven door movement or slight creaking.
Cold Connecticut winters accelerate wear. Metal contracts in freezing temperatures. Spring tension increases. The metal becomes more brittle. That's why Glastonbury homeowners often see spring failures between November and March.
Your door won't tell you politely. But it will hint. Listen for a loud bang or crack when you open or close the door. That's often the moment of failure. Before that, watch for:
- Door that feels heavier than usual when opening, Jerky, uneven movement as the door rises, Visible gaps or rust on the spring itself, Door closing too quickly or not opening all the way
If you notice any of these, don't keep using the door. Every cycle puts more stress on the broken or weakened spring and the opener. You risk damage to the opener motor, cables, or worse, the door crashing down unexpectedly. We've responded to emergency calls in Wallingford and Durham where a failed spring turned into a $2,000 repair instead of a $300 one because the homeowner kept operating the door.

This depends on which type you have and how much damage occurred. A single torsion spring replacement typically runs $250 to $400. Extension springs are usually $150 to $300 per spring. If both springs failed (they often do because they age together), double that cost.

Why the range? Spring quality varies. Heavy-duty commercial springs cost more than standard residential ones. Your door size matters. Your location within Glastonbury (or nearby areas) affects travel time and labor hours. We always provide a free estimate before starting work, so you know the exact cost upfront.
I've seen homeowners attempt this. Stop. Garage door springs are not a DIY project.
The tension is lethal. A fully wound torsion spring can snap and cause serious injury or death. Even extension springs, which seem simpler, are dangerous. They're under constant load. Releasing that tension incorrectly can break bones or cause lacerations. Our technicians use specialized tools and follow strict safety protocols. We also check the cables, pulleys, and door balance while we're there, catching secondary damage before it becomes expensive.
We can schedule a free quote for spring replacement and get the job done same-day in most cases. Call us or book online.
Stop using your garage door immediately. If it's stuck open, close it carefully by hand if the door isn't too heavy. If it's stuck closed, leave it until a professional arrives. Don't try to force the opener. You'll burn out the motor.
Next, call a local technician. Garage Door Company Glastonbury responds to emergency calls 24/7. We'll inspect both springs (even if only one snapped), check the cables and hardware, and replace what's needed.

You can't prevent springs from eventually wearing out. But you can extend their life. Lubricate springs twice yearly with garage door lubricant. Keep tracks clean and aligned. Have a professional inspect your door annually as part of seasonal maintenance. Springs that are well-maintained can sometimes reach 10 years instead of failing at 7.
If your door is older than 8 years and you haven't replaced the springs yet, schedule an inspection now. It's cheaper than an emergency repair, and you'll avoid the inconvenience of being stuck.

How long do garage door springs last? Most residential springs last 7 to 9 years under normal use, or about 10,000 to 15,000 opening cycles. Life expectancy depends on door weight, frequency of use, climate conditions, and maintenance. Springs installed in older homes or used more heavily may fail sooner.
Can I replace just one spring if both are the same age? Technically yes, but both springs are likely near the end of their lifespan. Replacing only one means the other will fail soon after. Most professionals recommend replacing both at once to restore proper door balance and avoid another service call.
What's the difference between torsion and extension springs? Torsion springs are mounted above the door on a shaft and twist to provide lift. They're more durable and common in modern doors. Extension springs run along the sides and stretch. They're less common now but still found in older systems. Both types can snap suddenly.
Is a snapped spring an emergency? Yes. A broken spring makes your door inoperable and unsafe. Don't attempt to open or close it repeatedly. Contact a professional immediately. We offer same-day service for spring failures across Glastonbury and surrounding towns.
Why did my spring snap without warning? Metal fatigues over time and loses strength. Cold weather accelerates the process because metal becomes brittle in freezing temperatures. Springs rarely give obvious warning signs before they fail, which is why annual inspections matter.
