Garage Door Spring Types in Madbury: Torsion vs. Extension Explained
2026-06-11 7 min read
Your garage door relies on springs to lift roughly 400 pounds with ease. Most homeowners never think about this until a spring snaps and the door won't budge. Understanding which type of spring you have matters because repair costs, replacement timelines, and safety risks differ significantly between torsion and extension systems.
What Are Garage Door Springs?
Springs counterbalance the weight of your door. Without them, you'd need serious arm strength to open your garage manually. Two main types exist: torsion springs and extension springs. See our guide on garage door cost & pricing in madbury, nh: what you.
Torsion springs wind tightly above your garage door opening. They store energy through twisting motion, releasing it as your door opens. These are the heavy hitters of the spring world. Most modern doors, especially heavier or wider ones, use torsion springs because they're smoother, quieter, and last longer.
Extension springs run horizontally along the sides of your door tracks. They stretch and contract like rubber bands, extending as the door lowers and contracting as it rises. Older homes and lighter doors often have extension springs. They're cheaper upfront but wear out faster.

Torsion Springs: The Premium Choice
Torsion springs typically last 7 to 9 years with regular use. A single torsion spring supports the entire door weight, so when it snaps, your door becomes dead weight. You'll hear a loud bang or crack from the garage, then notice the door won't open at all.
The good news? One spring replacement usually solves the problem. The challenging part is that torsion springs carry enormous tension. A snapped spring isn't a DIY fix. The coil unwinds explosively, and improper handling causes serious injury or property damage.
Torsion systems cost more to replace than extension springs, typically ranging from $200 to $400 per spring depending on your door size and local labor rates. For a detailed breakdown of what you might expect to spend, check our guide on garage door cost and pricing in Madbury.
Extension Springs: The Budget Alternative
Extension springs hang on both sides of your door tracks. Because the load splits between two springs, each one works less hard. This sounds good until you realize both springs wear out at roughly the same time.
When one extension spring snaps, the other typically fails within weeks or months. Most professionals replace both simultaneously to avoid a second service call. This dual replacement actually makes economic sense.
Extension springs cost $150 to $250 per pair installed. They're gentler on your wallet initially but don't last as long as torsion springs. Expect replacement every 5 to 7 years with average use.

How to Identify Your Spring Type
Look above your garage door from inside the garage. If you see a wound metal coil centered horizontally above the door, you have a torsion spring. If you see springs running lengthwise along both sides of the tracks, those are extension springs.
Don't touch or adjust springs yourself. The tension is dangerous. If you suspect a problem, contact a professional. We offer emergency garage door service in Madbury with same-day options when springs fail unexpectedly.
Warning Signs of Spring Failure
A snapped or failing spring usually announces itself. Your door becomes heavy to open manually. The door may hang unevenly or stick partway. You might hear creaking, popping, or a sudden loud crack.
If your door struggles even when the opener works, springs are wearing out. Don't ignore this. A broken spring on the ground creates a safety hazard and makes your door inoperable. Learn more about snapped springs and what to do before you need emergency help.
Maintenance Keeps Springs Healthy Longer
Regular lubrication reduces wear on both spring types. A light coat of garage door lubricant twice yearly extends spring life by 1 to 2 years. It's one of the cheapest preventive measures available.
Proper maintenance also catches small problems before they become expensive repairs. Our guide to garage door lubrication covers the budget fix that stops costly repairs.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years, while extension springs last 5 to 7 years. Lifespan depends on usage frequency, climate, and maintenance. Regular lubrication can extend life by 1 to 2 years.
Can I replace just one spring? With torsion springs, yes. With extension springs, professionals recommend replacing both simultaneously since they wear at similar rates and one failure usually precedes the other by weeks.
What does a broken spring cost to fix? Torsion spring replacement runs $200 to $400 per spring. Extension springs cost $150 to $250 per pair. Labor varies by location and complexity, so request an estimate from a local technician for accuracy.
Is a snapped spring dangerous? Yes. Snapped springs create tension hazards and make doors inoperable. Never touch a broken spring. Call a professional immediately for safe removal and replacement.
Why is my door suddenly heavy? Springs are likely failing. A working spring system makes your door feel nearly weightless when opening manually. Heavy resistance means springs are losing tension and need professional inspection.
