Garage Door Springs in Cornelius: Torsion vs. Extension (Which Do You Have?)
7 min read A2Z Garage Doors
Your garage door spring just snapped, and you're staring at a door that won't budge. In our years serving Cornelius and surrounding areas, we've seen this problem again and again. The first question homeowners ask is: "What type of spring do I have, and how much will it cost to fix?" The answer depends on whether you have a torsion spring or an extension spring. Each works differently, fails differently, and costs differently to replace.
What Are Torsion Springs?
Torsion springs sit horizontally above your garage door opening, mounted on a metal shaft. When you open your door, these springs twist (or "torque") to counterbalance the weight of the door. As the door closes, the springs unwind slowly, controlling the descent. Most modern homes built in the last 20 years use torsion springs because they're safer, last longer, and provide smoother operation.
A typical torsion spring lasts 7 to 9 years with average use (opening and closing about 3 to 5 times daily). They handle the weight more evenly than their counterparts, which is why professional installers prefer them. When a torsion spring fails, the door becomes nearly impossible to open by hand, and you'll hear a loud bang or crack when it snaps.
What Are Extension Springs?
Extension springs run along both sides of the door, parallel to the horizontal tracks. Instead of twisting, they stretch and contract as the door moves. When you open the door, the springs extend. When you close it, they contract and help pull the door down. Older homes, particularly those built before 2000, often have extension springs.
Extension springs typically last 5 to 7 years. They wear faster because they're constantly stretching under tension. When one snaps, you might feel the door drop suddenly or hear a loud snap. Some extension springs have safety cables running through them to prevent the spring from flying across your garage if it breaks, which is important for injury prevention.

Key Differences That Matter
The main differences come down to safety, longevity, and cost. Torsion springs are enclosed in a shaft and safer if they fail because they can't snap across the garage. Extension springs are exposed and can be dangerous if the safety cable fails. Torsion springs last 2 to 4 years longer on average, so you'll replace them less often over the lifetime of your home.
Cost varies too. A single torsion spring typically runs more per unit than an extension spring, but because torsion springs last longer and you usually need only one or two, the long-term cost often works out to be similar or even cheaper. When you need an estimate, always ask the technician to specify which type you have and why replacement is necessary.
If you're not sure which springs you have, look above your door. Torsion springs sit on a shaft above the opening. Extension springs run along the sides. Many homeowners discover their spring type only when something goes wrong, but knowing this detail helps you understand your repair options and prevent future problems.
When to Call a Professional
Never attempt to replace garage door springs yourself. These components are under extreme tension and can cause serious injury if mishandled. A single spring might support 300 to 400 pounds of force. When springs snap, that force releases suddenly, turning a spring into a dangerous projectile. We've treated plenty of DIY injuries that could have been prevented with a single phone call.

Frequently Asked Questions
Can I replace just one spring if I have two? We recommend replacing both springs at the same time, even if only one has snapped. The unbroken spring has the same age and wear, so failure is likely within months. Replacing both ensures balanced operation and prevents a second emergency service call.
How do I know if my spring is about to fail? Listen for squeaking or creaking sounds above the door. Look for visible gaps in the spring coils or an off-center door that sits lower on one side. These signs indicate wear. Some springs show rust or corrosion before snapping, which accelerates failure.
Is a torsion spring always better than extension? Torsion springs are safer and last longer, making them the better choice for new installations and replacements. If you have extension springs that are working fine, there's no urgency to switch unless one fails or you're upgrading your door system.
How much does a spring replacement cost near me? Cost depends on whether you need one or two springs, your spring type, and door size. Torsion springs typically range from $200 to $400 per spring installed. Extension springs run $150 to $300. Call 541-627-8979 for a free quote.
Can I open my garage door if the spring is broken? Do not attempt to open a door with a broken spring. The door is extremely heavy without spring support and can crash down unexpectedly, causing injury or property damage. Contact a professional immediately for safe removal or repair.
