Garage Door Springs in Goffstown, NH: Types, Cost & When to Replace
2026-07-08 7 min read
Here's what most homeowners don't realize about garage door springs: they're doing 80% of the work every time your door opens and closes. When a spring snaps, your garage door becomes a 300-pound paperweight. Understanding the two main types, what they cost, and when they need replacing can save you hundreds in emergency repairs and keep you safe.
Two Types of Springs: Know Which One You Have
Your garage door uses either a torsion spring or extension springs. These aren't interchangeable, and choosing the wrong one will cost you.
Torsion springs sit horizontally above your door on a metal shaft. They twist to lift the door's weight. One torsion spring can handle most residential doors. They're precise, durable, and last 7 to 9 years with normal use. When they fail, the door stops working entirely.
Extension springs hang vertically on both sides of your door track. They stretch to create lifting force. You typically have two, sometimes four. They're cheaper upfront but fail more often and last only 5 to 7 years. A snapped extension spring means the door suddenly becomes unbalanced.
Torsion springs are the better investment for Goffstown homes because they're safer and more reliable. But whatever type you have, replacement is critical work. Springs are under extreme tension, and improper installation or removal can cause serious injury.
Why Springs Fail (And It's Not Always Age)
Springs wear out from tension cycles, not just time. Every open-close cycle counts as one cycle. A door that opens and closes 4 times daily completes 1,460 cycles per year. After 7 to 9 years, metal fatigue sets in. The spring weakens and eventually snaps.
But springs fail early for other reasons too. Rust from New Hampshire's salt and moisture accelerates failure. Lack of lubrication increases friction and wear. Imbalanced doors force springs to work harder than designed. Heavy snow on a closed door in winter adds extra stress.
You can extend spring life by having your door serviced annually. Our garage door maintenance guide covers the basics homeowners miss, including lubrication points that cost nothing but add years to your springs.

Spring Replacement Cost: What to Budget
A single torsion spring replacement typically costs $200 to $400 in parts and labor in the Goffstown area. If both extension springs fail (common), expect $300 to $500 total. Emergency or same-day service costs more, often 25% to 50% above standard rates.
Don't ignore a broken spring hoping it'll last another month. A snapped spring forces your opener to work harder, straining gears and motors. You risk a $500+ opener replacement when a $300 spring job would have solved it.

When to Replace vs. When to Repair
If one spring is broken, both should be replaced at the same time. Replacing only one creates an imbalance. The remaining spring ages faster under extra load, and you'll pay for another service call within months.
Repair isn't really an option for broken springs. Springs can't be welded or patched safely. Replacement is the only safe choice.
Prevention is your cheapest strategy. Annual maintenance catches worn springs before they snap. Lubricate the springs and tracks, check door balance, and watch for rust. Small preventive work keeps springs healthy and saves emergency calls.

Safety Matters
Never attempt spring replacement yourself. Springs hold 300+ pounds of tension. Improper release or installation causes crushing injuries, eye damage, and worse. Professional technicians have the right tools, training, and insurance. It's one repair where DIY isn't worth the risk.
If your garage door suddenly feels heavy, won't open, or hangs unevenly, springs are likely the issue. Don't keep forcing the opener. Call us for a same-day diagnosis and honest repair estimate.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years; extension springs 5 to 7 years. Lifespan depends on cycles (open-close frequency), maintenance, and weather exposure. Regular lubrication extends life.
Can I replace just one spring? No. Replacing one spring creates imbalance and accelerates wear on the remaining spring. Always replace both springs together for even wear and safety.
What does a snapped spring sound like? A loud bang or crack, often from the garage. The door may hang crooked or refuse to open. Stop using the door immediately and call for service.
Is spring replacement an emergency? It depends. If your door is stuck open, you have a security issue. If stuck closed, it's inconvenient but not urgent. We offer same-day estimates and repairs for both scenarios.
How much does emergency spring repair cost? Standard replacement runs $200 to $400. Same-day or evening service typically costs 25 to 50% more. Call for a real quote based on your situation.
