Torsion vs. Extension Springs: Which Type Do You Have in Plaistow?

2026-07-18 7 min read

A customer called last Tuesday asking whether her garage door had "the spring that goes side to side or the one that hangs down." She couldn't describe it clearly, but the question itself told me everything. Most homeowners in Plaistow don't realize there are two distinct types of garage door springs, and knowing which one you have is essential before any repair work begins. If you're facing a snapped spring, planning maintenance, or just curious about your setup, this distinction matters more than you'd think.

Two Springs, Two Different Jobs

Your garage door relies on springs to counterbalance the weight of the door itself. Without them, your opener would burn out in months trying to lift hundreds of pounds. The two main types are torsion springs and extension springs. See our guide on garage door maintenance in plaistow: why lubrication and inspection matter most.

Torsion springs sit horizontally above your door opening, mounted on a shaft that runs perpendicular to the door. They twist or wind up to store energy. Most modern homes and commercial setups in the region use torsion springs because they're more durable, smoother, and safer. They last roughly 7 to 9 years under normal use.

Extension springs hang vertically on either side of your door opening, running along the horizontal tracks. They stretch or extend to support the door's weight. Older homes and budget installations often have these. They're simpler but less forgiving when they fail. A snapped extension spring can drop suddenly without warning, which is a genuine safety hazard. Read about when to replace your garage door opener in plaistow.

How to Tell Which Type You Have

Stand inside your garage with the door closed. Look up above the door frame.

If you see a horizontal rod running the full width of the opening with coils wrapped around it, that's a torsion spring. The springs themselves look like a twisted metal coil under heavy tension.

If you see two separate springs hanging vertically along the left and right sides of the door, those are extension springs. They'll be attached to cables and pulleys near the top corners.

This matters because repair costs and replacement timelines differ. A torsion spring replacement typically costs more than an extension spring, but torsion springs are far safer and more reliable long term. If you've had a snapped spring, understanding which type failed helps us provide an accurate estimate and timeline for your area.

Why This Matters for Your Repair

When you contact a garage door professional, telling us whether you have torsion or extension springs speeds up diagnosis. If your door won't open or won't stay up, the problem could stem from either type of spring. An extension spring failure often feels like a sudden drop or resistance. A torsion spring problem usually manifests as a slow close or wobbling door.

More importantly, safety depends on correct identification. Torsion springs store enormous energy and require specialized tools to replace safely. Extension springs, while simpler, can snap unexpectedly. We've written about what causes springs to fail and the real cost involved. You might find our article on snapped springs in Plaistow helpful for understanding why replacement beats temporary fixes every time. We also maintain a guide comparing repair versus replacement so you can make an informed decision about your specific situation.

Misidentifying your spring type can lead to ordering the wrong part, causing delays and frustration. It can also create safety risks if someone untrained attempts a repair on the wrong mechanism.

When to Replace Springs

Most garage door springs in Plaistow get 7 to 9 years of service before they need replacement. Some factors shorten this lifespan: frequent cycling (opening and closing multiple times daily), rust from humidity or road salt, and lack of lubrication. Winter months can be particularly hard on springs throughout New Hampshire. The cold makes metal brittle, and salt spray accelerates corrosion.

Rather than waiting for a spring to snap unexpectedly, consider proactive replacement once you hit the 7 to 8 year mark. This approach prevents emergency calls and keeps your family safer. We can inspect both spring types during routine maintenance and give you a honest timeline for when replacement makes sense.

Don't attempt spring replacement yourself. The tension stored in these components is dangerous. A slip can cause serious injury. Professional technicians have the right tools, experience, and insurance to handle this work safely.

Frequently Asked Questions

Q: Can I replace just one spring if only one snapped? A: Not recommended. Springs age together. If one snapped, the other is near failure. Replacing both ensures balanced operation and prevents a second failure days later. This saves money and frustration long term.

Q: How long does a spring replacement take? A: Typically 1 to 2 hours for either type. Our technicians work efficiently without sacrificing safety. We'll provide a time estimate when you call for your same-day service.

Q: What's the cost difference between torsion and extension spring replacement? A: Torsion springs cost slightly more due to complexity and labor time. Extension springs are cheaper upfront but less durable overall. We'll quote both options during your free estimate.

Q: Are there warning signs before a spring snaps? A: Yes. Listen for squeaking, creaking, or grinding sounds. If the door feels heavier or moves unevenly, get it inspected. Don't ignore these signs.

Q: Do I need both springs replaced at the same time? A: Yes, for safety and performance. Mismatched spring ages cause imbalanced door movement and accelerated wear on your opener.
