Garage Door Springs in Walpole: Torsion vs. Extension and When to Replace
2026-07-23 7 min read
After 15 years on service calls in Walpole and across the South Shore, I can tell you that garage door springs in Walpole confuse homeowners more than almost any other component. Here's the straight answer: most residential doors use torsion springs (mounted above the door, one or two per opening), while extension springs (on the sides) are less common but still out there. A snapped spring means your door won't open safely, and you need a pro to fix it same day if possible.
What Are Torsion Springs, Really?
Torsion springs do the heavy lifting. They're wound metal coils that store rotational energy. When you open the door, that tension unwinds and counterbalances the door's weight. When you close it, the spring rewinds. See our guide on garage door safety in walpole: what homeowners miss most.
Here's what matters: torsion springs last roughly 7 to 9 years with normal use (about 10,000 cycles). If your door gets heavy traffic or sits in an unheated garage through New England winters, you might see failure sooner. Cold temperatures make metal brittle, which is why we see more snapped springs in January and February around here.
A typical residential door needs one or two torsion springs depending on weight. Heavier doors (insulated models, steel construction) use two springs to share the load. If one breaks, the other can't handle the job alone, and your door either won't open or will slam down dangerously. Read about garage door repair cost in walpole: what to expect from your estimate.
Extension Springs: The Side-Mounted Alternative
Extension springs work differently. They're mounted horizontally on each side of the door opening and stretch as the door closes. They're cheaper upfront but typically wear faster and need safety cables.
If you have extension springs, they usually indicate an older installation or a retrofit in a tight space. New construction in Walpole almost always specifies torsion because they're more reliable and safer. That said, if your springs are extension type, don't panic. We can repair or replace them with the same system or upgrade to torsion if the framing allows.
Why Springs Snap (And What You Can't Control)
A broken spring is rarely sudden without warning. You'll notice the door getting harder to open, or the opener straining more than usual. Sometimes you'll hear a loud bang from the garage. That's the spring giving up.
Common causes include:
* Rust and corrosion from moisture and salt (heavy in coastal Massachusetts winters) * Overextension from improper garage door maintenance * Manufacturing defect (rare but happens) * Wear from thousands of open/close cycles
The tricky part: you can't easily inspect springs yourself without risking serious injury. A snapped spring under tension can cause cuts or worse. This is where professional help isn't optional. We've covered the safety essentials in more detail over at our garage door safety guide for Walpole homeowners, and springs are at the top of that list.

Spring Replacement Cost and What's Included
Here's what you're looking at for garage door springs in Walpole: $200 to $400 for a single torsion spring replacement, or $300 to $500 for two springs. Labor typically runs $150 to $250 depending on how accessible your springs are and whether the door opener needs recalibration.
I always recommend replacing both springs at the same time, even if only one is broken. The second one is right behind in age and cycles. Replacing one and then the other fails three months later costs you two service trips. Better to do it once.

DIY Warning: Why You Shouldn't Touch Springs
Springs carry hundreds of pounds of tension. Trying to adjust, remove, or replace them without proper tools and training can result in the spring unwinding violently. I've seen hands badly cut and fingers broken. It's not worth the risk or the money you think you're saving.

Frequently Asked Questions
How do I know if my garage door spring is broken? Your door will feel heavier to open, the opener will strain audibly, or you'll hear a loud bang from the garage. The door may stop partway or not open at all. Never force it; call a professional immediately.
Can I replace just one spring? Technically yes, but both springs are usually the same age. Replacing both at once prevents a second failure weeks later and saves you a second service call and labor cost.
How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal residential use (around 10,000 cycles). Cold winters and frequent use can shorten that lifespan.
Is spring replacement covered under warranty? Most springs carry a 1 to 3 year limited warranty against defects. Normal wear is not covered. Check your paperwork or ask us during your estimate.
What's the difference in cost between torsion and extension springs? Torsion springs cost slightly more upfront but last longer and are safer. Extension springs are cheaper but require regular inspection and safety cable maintenance. Long-term, torsion is the better investment.
