Garage Door Spring Types in Newfields, NH: Torsion vs. Extension Explained
2026-06-13 7 min read
Your garage door has springs. You probably don't think about them until one snaps and your door won't budge. The two main types are torsion and extension springs, and understanding the difference could save you money and keep your family safer. Here's what you need to know about garage door springs in Newfields.
What Are Torsion Springs?
Torsion springs sit above your garage door opening, running horizontally along a metal rod. They work by twisting (or torquing) as your door moves up and down. When you open your garage door, these springs unwind and help lift the heavy panel. When you close it, they wind back up.
Torsion springs are the more common choice in modern homes, especially in New England where we deal with temperature swings. They're built to last 7 to 9 years with normal use, though heavy daily use shortens that lifespan. Because they're mounted high and under serious tension, a snapped spring is dangerous to replace yourself. The stored energy can cause serious injury.
The upside? Torsion springs give you smoother, more controlled door movement and tend to be quieter than their counterparts.
What Are Extension Springs?
Extension springs run along the sides of your garage door, above the horizontal tracks. Instead of twisting, they stretch and contract like, well, springs. As your door opens, they extend. As it closes, they contract back. They're typically cheaper upfront and easier to replace, which is why older homes and budget-conscious builders often use them.
Here's the catch: extension springs wear faster in cold climates. New Hampshire winters are tough on them. They typically last 5 to 7 years. Plus, if one breaks, your door can drop suddenly. That's why extension springs come with safety cables running through them, designed to catch the spring if it fails.
Which Type Do You Have?
Look above your garage door opening from inside your garage. If you see a long metal rod running horizontally with coils wrapped around it, you have torsion springs. If you see springs on both sides running along the tracks, those are extension springs.

Why Your Springs Fail
Springs fail because they fatigue over time. Each time your door cycles up and down, your springs are working. After thousands of cycles, the metal loses its ability to bounce back. Cold weather accelerates this. Rust, dust, and lack of lubrication make it worse.
A snapped spring isn't a slow fade. It's usually sudden. Your door becomes too heavy to lift, or it won't stay open. That's your cue to call a professional.

Spring Replacement: DIY Isn't Safe
I'll be straight with you: replacing garage door springs yourself is not worth the risk. Torsion springs sit under 200 to 400 pounds of tension. A slipped tool or misstep can cause serious injury or death. Extension springs are less dangerous but still require expertise to balance properly.
Our technicians at Newfields Garage Doors have the tools, training, and insurance to do this right. We charge fair prices because we believe in honest pricing, not fear markup. When you explore our spring services, you're getting real expertise at a real price.
Cost and Timeline
Spring replacement typically costs between $200 and $400 per spring, depending on the type, quality, and your door's weight. We offer free estimates, so you'll know the cost upfront. Most replacements happen same-day or next-morning, depending on when you call.

Preventing Spring Failure
You can't stop springs from eventually failing, but you can slow it down. Lubricate your springs and tracks twice a year with garage door lubricant. Avoid slamming your door or forcing it if it feels heavy. Keep your garage reasonably dry to reduce rust.
Most importantly, have your springs inspected annually. A worn spring shows signs before it snaps: jerky movement, uneven door travel, or a door that won't stay open on its own.
If you're dealing with a snapped spring right now, don't try to force your door open. Call us for emergency service and we'll get you back in business fast.
Your garage door springs are too important to ignore and too dangerous to DIY. Let's handle it the right way.
Frequently Asked Questions
How do I know if my garage door spring is about to break? Watch for jerky door movement, one side of the door rising faster than the other, or a door that won't stay propped open. These are warning signs that a spring is wearing out and may snap soon.
Can I use my garage door if one spring is broken? No. Operating your door with a broken spring puts extra stress on your opener and can cause it to fail too. It's also unsafe. Stop using it until the spring is replaced.
How long does spring replacement take? Most spring replacements take 1 to 2 hours from start to finish. We often complete them same-day if you call early.
Why is torsion spring replacement more expensive than extension? Torsion springs require specialized equipment, precise balancing, and more technical skill. The higher cost reflects that expertise and the added safety measures required.
Do both my springs need to be replaced at the same time? Yes. Springs are sold and replaced in pairs to keep your door balanced and functioning safely. Replacing just one creates an imbalance that wears your opener faster.
