Garage Door Springs in Newmarket, NH: Types, Cost & When to Replace

2026-05-22

Garage door springs fail without warning, and most homeowners have no idea what type they have or how much replacement costs. The short answer: you have either torsion springs (one or two mounted above the door) or extension springs (one on each side), and a snapped spring typically runs $200 to $400 for parts and labor combined. We'll walk you through both types so you know what to expect when you call for a same-day estimate.

What Are Garage Door Springs, and Why Do They Matter?

Your garage door weighs 300 to 500 pounds. Without springs, you'd need superhuman strength to open it manually. Springs counterbalance that weight, making the door feel nearly weightless when you push the button or pull the handle. They're under constant tension, cycling roughly 10,000 times per year. That's why they wear out faster than most people realize. Most springs last 7 to 9 years, not 10 or more.

When a spring snaps, your door becomes stuck, your opener strains (sometimes breaking too), and you're paying emergency rates if it happens on a weekend. The good news: spring replacement is straightforward and affordable when you catch it early.

Torsion Springs vs. Extension Springs

Torsion springs mount horizontally above your garage door opening. One or two springs twist to lift the door. They're the most common type in modern homes and generally last longer because the load distributes evenly. A single torsion spring costs more upfront but handles the work more efficiently.

Extension springs sit along the horizontal tracks on each side of the door. They stretch as the door closes and contract to help lift it. Two springs share the load, so if one snaps, the other can sometimes hold the door (barely). Extension springs are cheaper initially but wear faster because each spring bears full load when the other fails.

Most homes in Newmarket built in the last 20 years have torsion springs. Older homes often have extension springs. Not sure which you have? Open your garage door manually (carefully) and look up. See a horizontal spring above the opening? That's torsion. See springs running along the side tracks? Extension.

Why Springs Fail

Rust and repetition are the main culprits. New Hampshire winters accelerate rust, especially in garages near salt roads. Humidity and temperature swings cause metal to expand and contract, creating tiny fractures that eventually snap. Poor maintenance speeds this up. If you haven't checked your garage door in a year or two, springs are wearing down right now.

One small habit helps: apply garage door lubricant to springs and hinges every six months. This reduces friction and slows rust. We cover this in our garage door maintenance guide for homeowners, which includes a full checklist you can follow yourself.

Cost Breakdown: What You'll Pay

A snapped spring replacement typically costs $200 to $400 for one spring. If you have two springs (common with torsion), expect $350 to $500 for both. The cost depends on spring type, your door's weight, and whether you need emergency service outside business hours.

Why the range? Premium springs last longer and cost more upfront but save money over 10 years. Budget springs are cheaper but may need replacement sooner. We always discuss this with customers before any work starts because you deserve to know what you're paying for.

Many local shops charge differently based on the day of the week or time of day. We don't. Honest pricing means the same cost whether you call Monday morning or Friday evening.

Signs Your Springs Are Failing

A snapped spring produces a loud bang or crack. The door may fall suddenly or hang crooked. The opener won't lift the door, even though the motor runs. These are emergency signals. Stop using the door immediately and call for help. Trying to force a broken spring can damage the opener or injure someone.

Slower warning signs include a door that feels heavier than usual, uneven opening, or a creaking sound. If the door moves slower each week, springs are weakening. Don't wait for a snap. Call us for an inspection.

When to Replace vs. Repair

Springs always need replacement, never repair. A snapped spring can't be welded or patched safely. Replacement is the only option. However, if one spring is failing but not yet snapped, we recommend replacing both at the same time. Why? The second spring is likely near the end of its life too. Replacing one now and one in six months means two service calls instead of one. Both springs together cost less than two separate visits.

Frequently Asked Questions

How long do garage door springs last? Most springs last 7 to 9 years with normal use. Rust, humidity, and frequent cycling can reduce lifespan. Proper maintenance and lubrication help extend durability.

Can I replace springs myself? Springs are under extreme tension and can cause serious injury if mishandled. Professional replacement is strongly recommended for safety and warranty protection.

What's the difference between a broken spring and a worn spring? A broken spring snaps suddenly, leaving the door stuck. A worn spring weakens gradually, making the door heavier or slower. Both need replacement, but worn springs give you time to schedule service.

Why does my door hang crooked after a spring breaks? One snapped spring means uneven weight distribution. The remaining spring (if you have two) can't support the door evenly, causing it to tilt. Stop using the door immediately.

Do you offer emergency service for broken springs? Yes. Call 1-978-737-4728 anytime. We respond to emergency requests quickly and offer same-day repairs when possible.
