Garage Door Springs in Walpole, NH: When to Replace Before Failure
2026-08-06 7 min read
A snapped garage door spring won't give you much warning, and when it fails, your door becomes a 300-pound dead weight. If you've ever dealt with a stuck garage door, you know how frustrating it is. But a broken spring isn't just inconvenient.it's a safety hazard that demands immediate attention from trained professionals.
What Garage Door Springs Do (And Why They Matter)
Your garage door relies on one of two spring systems: torsion springs or extension springs. Both store and release energy to lift and lower that heavy door smoothly. Without them functioning properly, your door opener motor can't do its job. See our guide on commercial garage doors in walpole, nh: repair vs. replacement.
Torsion springs sit above the door opening on a metal shaft. They twist and unwind thousands of times over their lifespan. Extension springs run horizontally along the sides of the door, stretching and contracting. Either way, they're under enormous tension and will eventually wear out.
Most springs last 7 to 9 years with regular use. That number drops if you open and close your door 10+ times daily. In Walpole and surrounding areas where winters are harsh, freeze-thaw cycles accelerate wear on metal components. Read about weather stripping & seals in walpole, nh: stop drafts before winter hits.
Warning Signs Your Springs Are About to Fail
Watch for these red flags before a complete break happens. Your door may move slowly even though the opener sounds normal. You might notice the door won't stay open or creeps down on its own. Some homeowners hear a loud bang or crack before the door stops working entirely.
If one spring fails in a two-spring system, don't assume the other is fine. When a snapped spring happens, the remaining spring bears all the load, and failure often follows within weeks. This is why we always recommend replacing both springs at the same time.
Never attempt DIY spring replacement. I've seen injuries that didn't need to happen. Springs are under several hundred pounds of tension. A slip means serious cuts, fractures, or worse. Call a licensed technician who has the right tools and experience.

Prevention: Extend Your Spring Life
Regular maintenance reduces the risk of unexpected spring failure. Lubricate springs and hinges twice a year with a silicone-based lubricant. Keep the door balanced and aligned so springs aren't fighting against friction. Have a professional inspect your springs annually, especially if your door gets heavy use.
Weather matters too. New Hampshire winters put extra stress on metal. Snow and ice buildup on your door increases the load springs must lift. Clear debris and keep seals in good condition. Our post on garage door maintenance this spring includes seasonal tips that prevent premature wear.

Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years under normal use. Frequent opening and closing, extreme weather, or poor maintenance shortens that timeline. Springs are measured in cycles (open-close pairs), not just years.
Can I replace one spring if the other is still working? We recommend replacing both springs at the same time, even if only one has failed. The working spring is nearing its end too and will likely fail soon under increased load.
What's the difference between torsion and extension springs? Torsion springs mount above the door and twist to lift it. Extension springs run along the sides and stretch. Torsion springs are more durable and safer but cost more to replace.
