Here's what most homeowners don't realize about garage door springs: they're not a "someday" fix. When a spring snaps, your door either won't open at all or falls hard enough to damage the track, opener, and anything underneath. In Duxbury's humid coastal climate, springs corrode faster than inland, cutting their lifespan from 7 to 9 years down to 5 to 7. If your door is jerky, slow, or makes a loud bang when closing, replacement isn't a luxury. It's a safety issue.
The North Shore gets salt air, moisture, and freeze/thaw cycles that beat up metal. A torsion spring that might last nine years in Boston's suburbs can start showing rust and weakness in six years here in Duxbury. That corrosion weakens the coil, reducing tension until the spring finally snaps under load. See our guide on sensor calibration: a complete guide for homeowners.
Most homeowners don't check their springs until something goes wrong. By then, you're stuck with a broken door and no way to get your car out. A snapped spring also puts extra strain on your garage door opener, which can fail next if you keep forcing the door open.
Salt air accelerates this wear. If your garage faces the ocean or sits near the coast, factor in earlier replacement. I've pulled springs off Duxbury homes that should've lasted eight years but gave up at five because of salt exposure and poor ventilation inside the garage.
Most residential doors in Duxbury use one of two types. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch to pull the door up. Both wear out, but they fail differently.
Extension springs are more common on older homes and smaller doors. They're cheaper to replace but more prone to breaking suddenly. Torsion springs are quieter and safer (they're contained better), but replacement is more technical. If you're not sure which you have, don't guess. Call us for a free assessment before you try anything yourself.
A snapped extension spring can whip off its cable and hit you. A broken torsion spring loses all tension at once, and the door crashes down. Either way, same-day replacement from a licensed tech is the only smart move.

A single spring replacement typically runs $150 to $300 per spring, plus labor. Most residential doors have two springs, so budget $400 to $700 total. The cost depends on spring type, wire gauge, and whether both springs are original.
If only one spring is broken but both are old, I always recommend replacing both. Springs wear together. Replacing one now and the other in six months means two service calls instead of one. It's cheaper upfront to do both at once.
Labor is where price varies. A straightforward torsion spring swap takes 45 minutes to an hour. If your door is stuck or the tracks are damaged, add another $100 to $200. Get an estimate before you commit. We provide free quotes and can often schedule same-day work if you call before 2 p.m.

I'm going to be blunt. Don't try this yourself. A torsion spring under tension can snap and cause serious injury. Extension springs can whip off and cut you. Even removing the tension safely requires a special tool and years of experience.
I've seen DIY attempts go wrong in ways that cost homeowners $2,000 to fix. A door that falls off its tracks, an opener that burns out, or worse, a hand injury that needs stitches. The $200 to $300 you save on labor isn't worth it.
Our techs are licensed and insured. We guarantee the work and stand behind every replacement. If something goes wrong, we fix it. That peace of mind is worth the cost.

Don't wait until your door gets stuck in the driveway or closes on your car. Spring problems only get worse.
How long do garage door springs last? Most torsion and extension springs last 7 to 9 years with normal use. In Duxbury's coastal climate with salt air and humidity, expect 5 to 7 years. Proper ventilation and occasional lubrication can extend lifespan slightly.
Can I replace just one spring? Technically yes, but both springs are the same age and wear together. Replacing one now means the other fails in months, requiring a second service call. Replacing both at once is more cost effective long term.
How do I know if my spring is broken? Common signs: door won't open, opens partway then stops, door falls hard when closing, loud bang or crack sound, or visible gap in the spring coil. If you see any of these, stop using the door and call for service immediately.
How much does spring replacement cost in Duxbury? Single spring replacement runs $150 to $300 per spring plus labor, typically $400 to $700 total for both. Final cost depends on spring type, wire gauge, and whether other damage exists. We provide free estimates.
Is spring replacement covered by warranty? New springs typically come with a 1 to 3 year manufacturer warranty. Our labor includes a 12 month workmanship guarantee. Damage from misuse or DIY attempts voids coverage.
