If your garage door won't budge and you hear a loud crack coming from above, a snapped spring is likely the culprit. This is one of the most common failures we see at Swanzey Garage Doors, and the good news is it's fixable. The bad news? You shouldn't fix it yourself. Here's what you need to know about garage door springs in Swanzey and what replacement actually costs.
Your garage door relies on either torsion springs or extension springs to lift a door that weighs 300 to 500 pounds. These springs are under constant tension, and over time, metal fatigue sets in. We typically see springs last 7 to 9 years with normal use, though that timeline shrinks in our New England winters.
When a spring snaps, it happens suddenly. There's no gradual warning, no slow decline. One day your door opens fine, and the next it won't budge. The spring essentially explodes, and the entire weight of the door falls on your opener motor, which wasn't designed to lift the door alone.
Cold weather accelerates wear. If you've dealt with a stuck garage door in January or February, spring failure was probably involved. Metal contracts in sub-zero temperatures, and the repeated stress of opening and closing in these conditions shortens spring life significantly.
Here's where I'm going to be straight with you: spring replacement isn't cheap, but it's necessary and not as expensive as emergency service often suggests elsewhere. At our shop, we charge between $250 to $450 for a single spring replacement, depending on whether you need a torsion or extension spring and the door's size.
If both springs are worn (which they often are), expect closer to $500 to $700 for the pair. We always recommend replacing both at the same time, even if only one snapped. The second spring is under the same stress and will fail within months if it hasn't already.

Labor accounts for most of that cost. Spring replacement requires specialized tools, precise tension adjustment, and real skill. A technician needs to safely unwind the old spring, install the new one, and balance it perfectly so your door opens and closes smoothly. One mistake creates a safety hazard or damages your opener.
I want to be clear: do not attempt this yourself. Springs are under roughly 200 pounds of tension per side. When they fail, they release that energy instantly. We've seen hands broken, faces cut, and garage walls damaged by people trying to save a few dollars.
Plus, if you mess up the installation, you void warranties and create liability issues. If someone gets hurt, your homeowner's insurance won't cover it.
When you call us about a snapped spring, we prioritize getting you back in your garage quickly. We handle same-day service across Swanzey and surrounding areas like Keene. Most jobs take 1 to 2 hours, depending on how many springs need work.
We'll give you a free estimate over the phone or in person before we start work. No surprises. We're transparent about what needs replacing and why, and we won't upsell you on parts you don't need.
If you want to understand the full scope of spring issues before calling, check out our detailed guide to garage door springs, costs, and replacement timelines. It covers both torsion and extension types and helps you know what questions to ask.
Here's the thing: you can't repair a snapped spring. You replace it. There's no middle ground. A broken spring can't hold tension, and no amount of patching brings it back.
However, if your spring is intact but making noise or showing surface rust, we can sometimes extend its life with lubrication and maintenance. That's worth a conversation with a technician. Learn more about keeping your garage door in top shape with regular maintenance.
If your door is stuck, don't force the opener. This will burn out your motor and make the bill much larger. Instead, schedule a free quote with us or call 1-978-440-3847. We'll come out, diagnose the problem, and give you honest pricing on the fix.
Spring failure is frustrating, but it's also completely fixable. The sooner you address it, the sooner you're back to normal. We've been serving Swanzey for years, and we take pride in fair pricing and work that lasts.
How long do garage door springs last? Most springs last 7 to 9 years with regular use. Harsh winters, frequent opening and closing, and lack of maintenance can shorten that timeline. We recommend having springs inspected annually.
Can I open my garage door manually if the spring is broken? Yes, but it's difficult and risky. The door is very heavy without spring tension. Use the emergency release cord in the garage, but be careful. Don't try to hold the door open by hand.
Why is spring replacement so expensive? The cost reflects specialized labor, precision tools, and safety equipment. A technician must safely handle high-tension springs and ensure perfect balance. This is skilled work, not a quick DIY task.
Should I replace one spring or both? Replace both. If one has failed, the other is near failure. Replacing both ensures balanced operation and prevents a second failure within weeks.
How quickly can you fix a snapped spring? We offer same-day service across Swanzey and nearby areas. Most jobs are completed within 1 to 2 hours from arrival. Call us to schedule.
