Garage Door Springs in Sherborn: Why They Fail and What It Costs
A customer called last Tuesday morning. His garage door was stuck halfway up, and he couldn't get it down. After 15 years on service calls, I knew before I even rolled up: snapped spring. It's the most common emergency I handle in Sherborn, and it happens fast. One moment your door works fine. The next, you hear a loud crack, and the whole system hangs there useless. The good news? It's fixable, but you need to act quickly.
What Causes Garage Door Springs to Fail
Garage door springs carry enormous tension. A standard residential door weighs 300 to 400 pounds, and the springs handle that load thousands of times a year. Over time, metal fatigues. Springs typically last between 7 and 9 years under normal use, not 10. When they wear out, failure comes without warning.
The two main types are torsion springs (wound around a metal rod above the door) and extension springs (running along the sides). Torsion springs are stronger and safer but cost more to replace. Extension springs are cheaper upfront but wear faster and pose greater safety risks if they snap.
Common culprits for early failure include rust from humidity, lack of lubrication, extreme temperature swings, and heavy use. If you're in the greater Boston area, our salty winters and humid summers accelerate corrosion. Regular maintenance catches these issues before they strand you.
The Real Cost of a Snapped Spring
This question hits every homeowner's wallet. A single torsion spring replacement runs $150 to $300 for parts and labor combined. Extension springs cost less, around $100 to $200. But if both springs fail (common, since they wear together), you're doubling that cost. Adding a service call fee typically runs $50 to $75 depending on whether you need same-day emergency dispatch.
I always recommend replacing both springs even if only one has snapped. It's false economy to fix one now and call me back in six months when the second goes. The labor is already there. One call, one trip, one solution.

Why You Shouldn't DIY Spring Repair
I'll be direct: don't attempt this yourself. Garage door springs operate under extreme tension. A slip, a miscalculation, a wrong tool choice, and you risk serious injury or death. I've seen fingers crushed, eyes injured, and worse. The springs can snap during installation and strike like a whip.
This is one repair where hiring a licensed technician isn't a convenience. It's a safety requirement. If you're interested in what makes garage door systems safe overall, read our guide on garage door safety in Sherborn for more context on tension systems.
Our team has the right equipment, insurance, and years of experience. We can replace springs correctly and safely in under an hour for most residential doors.
How to Know If Your Springs Need Replacement
Watch for these signs. If your door moves slowly, struggles to open fully, or feels heavier than usual, springs are weakening. A visible gap in the coil or rust streaks are red flags. Most telling: if you hear a loud bang or crack, stop using the door immediately and call for service.
Don't try to operate a door with broken springs. You risk damaging the opener motor, cables, and rollers. The repair bill compounds fast. A $200 spring job becomes $600 or more when other components fail.

Frequently Asked Questions
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years under normal residential use, depending on cycle frequency and maintenance. Proper lubrication and seasonal inspections extend their lifespan.
Can I replace just one spring? Technically yes, but both springs wear at similar rates. Replacing only one means the other will likely fail within months. Replace both together to avoid repeat service calls and save on labor.
What's the difference between torsion and extension springs? Torsion springs wind around a rod above the door and are safer, stronger, and more durable. Extension springs run along the sides, cost less, but wear faster and pose greater safety hazards if they snap.
Is spring replacement covered by warranty? Most manufacturers warrant springs for 1 to 3 years. After that, replacement is an out-of-pocket repair. We always provide a cost estimate before work begins.
