Garage Door Springs in Pittsburg, NH: Torsion vs. Extension (Which Do You Have?)
2026-09-02 7 min read
If your garage door won't open or you hear a loud bang from above, you've likely got a spring problem. The good news: knowing whether you have torsion or extension springs helps you understand the repair cost and timeline. In Pittsburg, most homes use one of these two types, and they behave very differently when they fail.
What Are Garage Door Springs?
Springs do the heavy lifting. Your garage door weighs 300 to 500 pounds, and springs counterbalance that weight so your opener doesn't burn out in six months. Without them working properly, you're stuck. Springs typically last 7 to 9 years depending on usage and maintenance.
There are two main designs: torsion and extension springs. Each works on a different principle, requires different tools to replace, and costs differently. Misidentifying which one you have can lead to ordering the wrong part or, worse, attempting a dangerous DIY fix.
Torsion Springs: What You Need to Know
Torsion springs sit horizontally above your garage door opening, mounted on a steel shaft. When the door closes, the spring winds up (torques), storing energy. When you open the door, that stored energy unwinds and lifts the door. They're compact, durable, and the most common choice in newer homes and commercial installations.
Advantages: longer lifespan, smoother operation, compact design, and predictable failure. Disadvantages: higher replacement cost (typically $200 to $400 per spring in Pittsburg) because installation requires specialized equipment and training. If a torsion spring snaps, you'll hear a loud metallic crack. The door won't move.
One spring often balances the entire door load. Some doors have two springs, but that's less common. When you hear "snapped spring," it's usually a torsion failure.
Extension Springs: How They Differ
Extension springs hang vertically on either side of your garage door opening, attached to cables that run over pulleys. As the door closes, these springs extend (stretch). When you open it, they contract and help lift. They're cheaper upfront but wear faster because they work harder with each cycle.
Advantages: lower initial cost ($100 to $250 per pair) and easier installation. Disadvantages: shorter lifespan, less smooth operation, and safety concerns. A snapped extension spring can cause the door to fall unevenly or the cable to whip dangerously.
Extension springs almost always come in pairs. If one fails, both should be replaced to maintain balance and prevent premature wear on the other side.

How to Identify Your Spring Type
Stand inside your garage with the door closed and look up. Do you see a horizontal wound coil above the center of the door? That's torsion. Do you see springs on both sides, parallel to the door tracks, running vertically? Those are extension springs. It's that simple.
If you're unsure, don't attempt a DIY diagnosis by touching or pulling anything. Springs under tension can cause serious injury. When you schedule a free quote with Pittsburg Garage Doors, our technicians will confirm the type and discuss replacement options without obligation.
Cost and Timeline
Torsion spring replacement typically costs more but lasts longer. Extension springs cost less upfront but may need replacement sooner. Both types benefit from regular maintenance. Check out our garage door maintenance guide for Pittsburg homeowners to learn how lubrication and inspection extend spring life by years.
In Pittsburg and nearby areas like Colebrook, we offer same-day replacement for both types. We carry common sizes in stock, so most jobs are done within 24 hours. Pricing depends on spring size, door weight, and whether you need one or both replaced.
Why Professional Installation Matters
Torsion spring installation requires a winding bar, safety cables, and precise torque settings. One mistake can cause the spring to unwind violently, causing injury or property damage. Extension spring installation is less dangerous but still demands proper cable alignment and pulley function.
Our technicians have 15 years of field experience. We handle the installation safely, test the balance, and adjust the opener settings to match the new springs. If you're curious about spring failure causes, read our deeper guide on why garage door springs fail.
Next Steps
If you suspect a broken spring, stop using the door immediately. A broken spring puts extra stress on your opener and can cause the door to jam or fall unexpectedly. Contact us today for same-day or emergency service.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years; extension springs last 5 to 7 years. Lifespan depends on cycle count (open/close frequency), maintenance, and climate. Regular lubrication extends life.
Can I replace just one spring? With torsion springs, yes. With extension springs, no. Extension springs always come in pairs because the load must be balanced equally on both sides to prevent binding.
What's the difference in cost between torsion and extension? Torsion replacement costs $200 to $400 per spring. Extension springs cost $100 to $250 per pair. Torsion costs more but lasts longer, so the total cost per year of use is often lower.
Is it safe to DIY garage door spring replacement? No. Springs under tension can cause serious injury or death. Professional installation is strongly recommended and often required by homeowner's insurance.
How do I know if my spring is about to fail? Listen for creaking, squeaking, or grinding sounds. Watch for jerky door movement, slower opening, or the door sagging on one side. These are warning signs. Schedule an inspection before complete failure.
