Garage Door Springs in Goffstown: Which Type Do You Have and Why It Matters
2026-09-13 7 min read
A customer called last Tuesday asking why their garage door wouldn't open. They'd watched a YouTube video and assumed they could identify and replace their spring themselves. After five minutes on the phone, I realized they didn't know whether they had torsion or extension springs. That knowledge gap could've cost them hundreds in wasted parts or a serious injury. Here's how to identify which type you have, why it matters, and what that means for your wallet in Goffstown.
Torsion Springs vs. Extension Springs: The Core Difference
Torsion springs sit horizontally above your garage door, centered on a metal rod. They twist and unwind to lift the 300 to 400 pounds your door weighs. Extension springs hang vertically on both sides of the door and stretch as it closes, then contract to help it rise. The distinction isn't academic. A snapped torsion spring requires different tools, different expertise, and different replacement costs than a snapped extension spring.

Most modern residential doors in Goffstown use torsion springs. They're more durable, last 7 to 9 years with normal use, and offer better balance. If your door was installed before 2005, you might still have extension springs. They're cheaper upfront but wear out faster and are more likely to snap without warning.
How to Tell Which One You Have
Look directly above your garage door from inside the garage. If you see a horizontal metal rod with a coil wound around it, you have torsion. That's the most common setup. The spring sits centered, usually with a cable drum on each end. Read about emergency garage door service in goffstown, nh: what to do when your door gets stuck.
If you see two springs, one on each side of the door frame, running vertically along the tracks, you have extension springs. They'll be clearly visible below the horizontal tracks, with pulleys at the ends.

Why Identification Matters for Cost and Safety
If a spring snaps, you cannot open your door manually without risking serious injury or damage. The door becomes a 400 pound dead weight. Trying to replace the wrong spring type wastes money on parts that won't fit and might damage your opener. Extension spring replacement costs less than torsion spring work because the labor is simpler. Torsion springs require tension calibration that only trained technicians should attempt.
Safety is the bigger issue. Both spring types store enormous tension. Releasing that tension incorrectly can cause springs to whip, metal to snap, or the door to drop suddenly. This isn't a DIY project, regardless of your confidence level. We've seen too many near-miss injuries from homeowners who tried to save a few dollars and ended up calling us for emergency service anyway.

Getting an Accurate Estimate
When you contact Garage Door Goffstown for a spring replacement, we'll identify your spring type, measure the exact specifications, and give you an honest estimate before any work starts. No surprises. If your door is older or you're not sure when the springs were last serviced, we can inspect the whole system and let you know if other components are wearing out.
Extension springs might cost less to replace than torsion springs, but that doesn't make them better. Torsion springs are the right choice for most doors because they balance better and last longer. Sometimes the cheapest option isn't the smartest one over the life of your door.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (opening and closing 4 to 8 times daily). Extension springs often wear out faster, around 5 to 7 years. Frequency of use and climate affect lifespan significantly.
Can I replace just one spring if the other is still working? If one spring snaps, the other is likely near the end of its life. Replacing both at once balances the door properly and prevents a second failure weeks later. It costs more upfront but saves money and hassle long-term.
What does a snapped spring sound like? A loud bang or crack, like a gunshot, usually from inside the garage. The door may drop suddenly or hang unevenly. Stop using it immediately and call for professional service.
Why do extension springs need safety cables? Safety cables prevent the spring from whipping across the garage if it snaps. They're required by code on all extension spring doors. If yours are missing, request them during replacement.
Does my homeowner's insurance cover spring replacement? Most policies don't, because springs are wear-and-tear items. Check your specific policy. Service calls and parts are usually your responsibility, which is why preventive maintenance helps you budget.
