Garage Door Springs in Wentworth, NH: Torsion vs. Extension (Which Do You Have?)
2026-08-23 7 min read A2Z Garage Doors
Here's what most homeowners don't realize about garage door springs: you likely have one of two completely different types, and they behave nothing alike. A snapped spring on a torsion system requires a different repair than one on an extension setup. If you own a home in Wentworth, NH, knowing which type you have isn't just academic. It affects your cost, your safety, and whether we can dispatch a technician for same-day service.
Two Spring Types: Know Which One Supports Your Door
Your garage door weighs between 300 and 500 pounds. That weight has to go somewhere when the door opens and closes. Springs handle that load through either tension or rotation. See our guide on how to tell if your garage door spring is broken in wentworth, nh.
Torsion springs sit above your garage door, running horizontally across the top. They twist (or wind) to store energy. When you open the door, that stored torque releases and lifts the weight. One torsion spring typically lasts 7 to 9 years with normal use. Two springs last proportionally longer because the load splits between them.
Extension springs hang vertically on each side of the door tracks. They stretch and contract like rubber bands. When the door closes, they extend. When it opens, they contract and pull the door up. Extension springs wear out faster than torsion springs, usually in 5 to 7 years, because the stretching motion creates more friction and metal fatigue.

If your door has cables running along the sides, you almost certainly have extension springs. If your door has a horizontal rod twisting above it, that's your torsion setup.
Why the Spring Type Matters for Repair Cost
Spring replacement isn't a do-it-yourself job. Both types store enormous amounts of energy. A snapped spring can snap back violently and cause serious injury. We always recommend professional service for this work.
The cost difference between the two types is real. Torsion spring repair generally runs higher because the springs themselves cost more, installation is more precise, and the calibration demands skill. Extension spring replacement is typically less expensive, but you often need both springs done at the same time to keep the door balanced.

Signs Your Springs Are Failing
A snapped spring makes itself obvious. You'll hear a loud bang (sometimes confused with a car backfire). The door becomes very heavy to open manually, or the opener won't budge it. Some doors won't open at all once a spring breaks.
But springs don't always snap suddenly. Weakening springs show gradual signs. The door moves slower than usual. The opener works harder and noisier. The door doesn't stay in the halfway position like it once did.
If you've noticed these changes, don't wait for a complete failure. A weakening spring puts extra stress on your garage door opener and can damage the tracks. Early replacement prevents a bigger bill down the road. We offer free estimates, so there's no risk in having us assess the situation.
When to Replace vs. Repair
Some technicians will patch a single extension spring. We don't recommend it. If one spring has failed, the other is probably close behind. Replacing just one creates imbalance, wears down the cable faster, and often leads to a second service call within months.
For torsion springs, replacement means handling the entire spring system. Professional recalibration ensures the door opens and closes smoothly at every height.
The smart move is a full spring replacement. It costs a bit more upfront but gives you years of balanced, reliable operation. Our technicians can discuss options when you schedule a free quote.
Professional Installation Matters
Spring installation requires the right tools, knowledge of door weight calculations, and understanding of safety protocols. If a spring is wound incorrectly, the door won't operate safely. We've seen amateur repairs cause garage door openers to fail prematurely and doors to close unexpectedly.
At Wentworth Garage Doors, we handle spring work as a precision craft. Proper installation means your door will last years longer and operate without the jerks and noise that come from rushed work.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs usually last 5 to 7 years. Lifespan depends on how often you open and close the door and whether the system is well-maintained. Salt air from winter conditions can accelerate wear.
Can I replace one spring instead of two? It's possible but not recommended. If one extension spring has failed, the other is likely weakening too. Replacing both ensures balanced door operation and prevents a second repair call in the near future.
What does a snapped spring sound like? A loud, sharp bang, often mistaken for a car backfire or gunshot. It happens in an instant. After the snap, the door becomes extremely heavy and won't open normally.
How much does spring replacement cost in Wentworth? Cost varies based on spring type (torsion costs more than extension), whether one or both springs need replacement, and any additional repairs. We provide free estimates so you know the exact price before work begins.
Is it safe to open my door if the spring is broken? No. A broken spring puts full door weight on the opener and cables. The door can fall suddenly or bind in the tracks. Stop using the door and contact a professional immediately.
