Here's what most homeowners don't realize about garage door springs: they're doing roughly 90 percent of the heavy lifting when your door opens and closes. Your garage door opener gets the credit, but those springs are the real workhorses. After 15 years on the trucks around Dudley, I've seen countless surprised faces when a spring fails and the door won't budge. Understanding what you have, how long it should last, and when it's time to call a pro can save you money and keep you safe.
Your garage door uses one of two spring systems, and knowing which one you have matters.
Torsion springs sit horizontally above your door opening. They're wound tight and store energy as your door closes. When you open the door, that stored energy helps lift the weight. Most residential doors in Dudley use torsion springs because they're durable and reliable. These typically last 7 to 9 years with normal use, meaning roughly 10,000 to 15,000 open/close cycles.
Extension springs run along the sides of your door tracks. They stretch as the door lowers and contract as it rises. They're less common in newer homes but you'll still find them on older installations. Extension springs also last 7 to 9 years but tend to wear unevenly if one side gets more stress than the other.
The key difference: torsion springs fail suddenly and predictably. Extension springs can snap without much warning, especially if one has already failed. Either way, a snapped spring means your door won't open, and your opener will strain trying to lift dead weight.
Springs don't just wear out from age. They wear out from cycles. A typical residential garage door operates 400 to 600 times per month if someone parks inside daily. That's roughly 5,000 to 7,000 cycles annually. Most torsion and extension springs are rated for 10,000 total cycles. Do the math: you're looking at 18 months to 2 years if you use your garage door constantly.
But here's the catch. Most manufacturers design springs for a 7 to 9 year lifespan under normal residential use. That's not because the spring physically lasts that long. It's because after 7 to 9 years, metal fatigue, temperature swings (especially brutal New England winters), and corrosion take their toll. The spring becomes brittle and unpredictable.
If your springs are past the 7 year mark, replace them before one fails. A proactive replacement costs less than an emergency call and prevents you from being locked out of your garage when you need it most.

I understand the temptation. Springs look simple. They're just metal coils, right?
Wrong. Those coils are under extreme tension. A torsion spring can store enough energy to launch a wrench across your garage or break your arm if something goes wrong. Every year I see injuries from people trying to save $200 on labor. The hospital bill runs $5,000 to $15,000. Not worth it.
Spring replacement requires specialized tools, proper safety cables, and years of experience reading the spring's condition. A technician from Garage Door Dudley knows exactly how much tension to apply and whether your door's hardware is safe to reuse. If a snapped spring damaged your cables or pulleys, we catch that during replacement.
When you schedule a free quote with us, we'll give you a transparent cost estimate and explain whether both springs need replacement. Many homeowners assume only the broken one needs attention, but if one spring has failed, the other is usually close behind.
If your garage door closes slowly, bounces at the bottom, or opens unevenly, springs are likely the culprit. Check our guide on troubleshooting a broken or stuck door for more signs of spring trouble.

If you want to extend spring life and catch problems early, routine maintenance matters. We recommend a maintenance schedule inspection once yearly, which often reveals spring wear before failure happens.
Spring problems don't fix themselves. A broken spring leaves you stranded and puts stress on your opener, potentially causing secondary damage. If you've noticed any of the warning signs above, schedule a free quote or call (508) 682-4590 right now.
We'll inspect both springs, test your door's balance, and give you an honest recommendation. Same-day service is available for emergency repairs across Dudley and surrounding areas.

How much does a garage door spring replacement cost? Spring replacement typically runs $200 to $400 per spring, including labor and parts. If both springs are old, replacing both at once is smarter than replacing one now and the other in six months. Emergency after-hours service adds $100 to $150.
Can I replace just one spring if only one snapped? Technically yes, but we don't recommend it. If one spring has failed, the other is usually near the end of its life too. Replacing both now prevents a second failure soon and keeps your door balanced and safe.
How do I know if my springs are torsion or extension? Torsion springs sit horizontally above your door. Extension springs run vertically along each side of the tracks. If you're unsure, take a photo and call us. We'll identify your system in seconds.
Do garage door springs need maintenance? Light lubrication once yearly helps, but springs don't need much beyond that. The real maintenance is replacing them on schedule before they fail unexpectedly.
Why did my spring break without warning? Metal fatigue happens silently over years. Springs lose elasticity and become brittle, especially after harsh winters. One day they just snap under normal use. Regular inspection catches the signs before total failure.
