Garage Door Spring Types in Millis: Torsion vs. Extension Explained
2026-07-22 7 min read
Here's what most homeowners don't realize about garage door springs: not all springs are created equal. I've spent 15 years on the trucks around Millis and nearby towns, and I can tell you that understanding whether your door uses torsion or extension springs can save you hundreds of dollars and keep your family safe. These two types work in completely different ways, and knowing the difference might be the smartest move you make this year.
What Are Garage Door Springs and Why They Matter
Your garage door weighs 300 to 500 pounds. Without springs, you'd need superhuman strength to lift it manually. Springs counterbalance that weight, making your opener's job possible and keeping your door moving smoothly. They're under constant tension, cycling thousands of times over their lifespan. When a spring fails, your door becomes a safety hazard and an expensive problem fast.
Springs typically last 7 to 9 years with normal use, depending on usage frequency and maintenance. Most Millis homeowners don't think about their springs until something goes wrong. That's when panic sets in.
Torsion Springs: The Heavy-Duty Choice
Torsion springs wind tightly around a metal shaft mounted horizontally above your garage door opening. As your door closes, the springs twist (torsion means twisting). This twisting motion stores and releases energy to lift and lower your door smoothly.
Torsion springs are the gold standard for most residential doors. They're more durable, quieter, and safer than their alternative. If you have a newer home or a door installed in the last 15 years, you almost certainly have torsion springs. They handle repetitive cycles better and last longer overall.
The downside? They cost more upfront. But that expense is worth it. A snapped torsion spring won't send pieces flying across your garage like an extension spring can. That safety difference alone makes them the preferred choice for families with kids or pets.
Extension Springs: The Budget Alternative
Extension springs hang vertically on both sides of your door opening. They stretch and contract as your door moves up and down. Think of them like rubber bands that extend when you pull them and snap back when released.
Older homes in the Millis area often have extension springs. They're cheaper to install and repair initially, but they wear faster and require more maintenance. Extension springs need safety cables running through them to prevent injury if they snap. Without those cables, a snapped spring can whip across your garage dangerously.
Extension springs typically cost less than torsion springs for replacement, but they fail more frequently. You might replace them every 5 to 7 years instead of 7 to 9. The math doesn't always favor the cheaper option.

How to Tell Which Type You Have
Stand in your garage and look above the door opening. Do you see a thick metal shaft running horizontally with springs coiled around it? That's torsion. Do you see springs hanging vertically on both sides? That's extension.
If you're unsure, don't guess. Call a professional. Misidentifying your spring type could lead to ordering the wrong replacement and wasting money. When you schedule a free quote, we'll identify your exact spring setup and give you an honest cost estimate before any work begins.
Spring Replacement: When and Why
A snapped spring means your door won't open or close properly. You might hear a loud bang when it happens. Some doors become completely stuck. Others might close partially but not open.
Never attempt to replace springs yourself. The tension in these springs is extreme. One slip can cause serious injury. I've seen amateur attempts go wrong badly. Our team at Garage Door Millis handles spring replacement safely and quickly.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (about 10,000 cycles). Extension springs last 5 to 7 years. Frequency of use, humidity, and regular maintenance all affect lifespan.
Can I replace one spring if only one breaks? We recommend replacing both springs at the same time, even if only one snapped. The second spring is likely near the end of its life too, and replacing both ensures balanced operation and prevents callback issues.
What's the average cost to replace garage door springs in Millis? Torsion spring replacement typically runs $200 to $400 per spring, while extension springs cost $100 to $200 per spring. Our free estimates give you exact pricing for your specific door and spring type.
Are extension springs dangerous? Extension springs are riskier than torsion springs because they're under high tension and can snap violently. Safety cables help contain them, but torsion springs are inherently safer for households with children or pets.
How do I know if my springs are failing? Signs include the door moving slowly, uneven opening, unusual noises, or visible wear. If your door feels heavier to open manually, springs are likely weakening. Don't ignore these warning signs.
