Garage Door Springs in Lynn, MA: When to Replace & What It Costs
2026-09-01 7 min read A2Z Garage Doors
Most homeowners never think about their garage door until something breaks. Then a snapped spring leaves you locked out of your garage, and suddenly you're scrambling for answers. After 15 years on trucks across Lynn and the North Shore, I've seen more spring failures than I can count. Here's what you need to know before it happens to you.
Why Garage Door Springs Fail (And They Always Do)
Springs aren't mysterious. They're just metal under constant tension, and tension has limits. Your garage door weighs 300 to 500 pounds. Every single day, those springs help lift and lower that weight hundreds of times. Over years, metal fatigues. It cracks. It snaps.
There are two main types: torsion springs sit above your door, and extension springs run along the sides. Torsion springs last 7 to 9 years with normal use. Extension springs might stretch that to 10 or 12, but not much longer. Once one fails, the other isn't far behind. I've never replaced a single spring without the homeowner calling back three months later about the second one.
Temperature swings in Lynn's winters and humid summers accelerate wear. Salt air near the coast corrodes metal faster too. If you live closer to the water, expect springs to need replacement on the shorter end of that timeline.
Signs Your Springs Are About to Break
Listen for the noise first. A loud bang or crack when your door opens means a spring just snapped. Stop using the door immediately. A snapped spring can't support the weight anymore, and forcing it risks injury or damage to your opener.
Before that bang, you might notice the door feeling heavier than usual. It struggles to open, even though your opener sounds normal. Sometimes the door tilts unevenly as it rises, which tells you one spring is already weaker than the other.
Don't ignore these warnings. I've seen homeowners ignore a wobbly door for weeks, then call in a panic when the second spring fails and they can't open the door at all. For more on spotting trouble early, check our guide to warning signs you need garage door repair.

What Spring Replacement Actually Costs
Spring replacement isn't cheap, but it's cheaper than ignoring the problem. A new torsion spring runs $150 to $300 per spring, plus labor. Most jobs involve replacing both springs at once, so expect $400 to $800 total before tax.
Extension springs are slightly less expensive per spring ($100 to $200), but the labor is similar. The real cost difference comes down to your specific setup. Older doors with custom or heavy-duty springs cost more. A professional estimate takes 15 minutes and gives you exact pricing for your door.
Don't try this yourself. I say that as someone who respects DIY work. Spring replacement involves dangerous tension. One slip and you could lose a finger or worse. Every year I hear about someone hurt trying to save $200. It's not worth it. Get a same-day estimate from Garage Door Company Lynn instead.
Why Professional Replacement Matters
When a spring breaks, your entire door assembly is out of balance. An amateur might replace the spring but miss other damage: bent tracks, worn pulleys, or a worn opener belt that's about to fail next month.
A proper job includes inspecting everything else while we're there. We check track alignment, test balance, and make sure your opener isn't straining. That inspection catches problems before they cost you more money.
Also, most springs come with a warranty only if a licensed technician installs them. DIY installation voids that coverage. If a spring fails early, the manufacturer won't cover it.

Frequently Asked Questions
How do I know if a spring is broken? You'll hear a loud bang or crack when the door operates. Afterward, the door either won't open at all or opens unevenly and tilts to one side. Stop using the door immediately if this happens.
Can I replace just one spring? Technically yes, but I don't recommend it. Both springs are the same age and wear at the same rate. Replacing one means the other fails soon after. Replace both at once to avoid a second service call.
How long does spring replacement take? Most jobs take 30 to 60 minutes from arrival to finish, depending on your door type and how worn the hardware is. We try to keep you out of the garage as little as possible.
Is spring replacement covered by homeowners insurance? Usually no. Spring failure is considered wear and tear, not damage. Check your policy, but don't count on coverage. Budget for the repair yourself.
What's the difference between torsion and extension springs? Torsion springs twist above your door and last 7 to 9 years. Extension springs stretch along the sides and last slightly longer. Torsion is more common and safer overall.
