Torsion springs are best for most Durham homes—especially newer doors—because they’re safer, last longer, and work smoothly in our humid summers. Extension springs are cheaper upfront but need more frequent checks and aren’t ideal for heavier modern doors.
What are torsion springs and how do they work?
Torsion springs mount above the garage door and twist to lift it. They use a shaft and cables to balance the door’s weight, making operation smoother and quieter. Unlike extension springs, they don’t stretch or snap outward, which reduces risk during repairs. In Durham’s older neighborhoods, many homes built before 2010 still have extension springs, but newer installations almost always use torsion. If your door was installed in the last 10 years, it likely has torsion springs—check the top bracket for a metal tube running across the header. Durham’s Trusted Broken Spring Replacement
What are extension springs and how do they work?
Extension springs stretch along the door’s horizontal tracks, pulling the door open as they extend. They’re simpler and cheaper to install, which is why they’re common in older Durham homes and rental properties. However, they’re more exposed to weather, pets, and kids, increasing wear. If your door has a pulley system with springs visible on either side of the track, you have extension springs. They’re fine for lightweight doors but can sag or break faster in Durham’s humid summers. Garage Door Repair cost guide
Pros of torsion springs: safety and longevity
Torsion springs last 15,000–20,000 cycles—about 10–15 years in Durham—because they’re under less stress than extension springs. They’re mounted above the door, so they’re out of reach of kids, pets, and weather, reducing damage risk. Their balanced lift also reduces strain on the door’s opener and tracks. In our humid climate, torsion springs resist corrosion better when properly lubricated. They’re the standard for modern doors and required in many newer builds. If you’re replacing a spring in a home built after 2015, torsion is almost always the right choice. Contact us for a free estimate
Pros of extension springs: lower upfront cost and easier DIY swap
Extension springs cost $50–$150 to replace, while torsion springs run $150–$300. That makes them attractive for landlords or budget-conscious homeowners in Durham’s older neighborhoods like Holloway or Forest Hills. They’re also easier to install if you’re comfortable with basic tools—though safety risks go up. However, they wear faster in our damp climate, often needing replacement every 5–7 years. If your door is lightweight and you’re not planning to upgrade soon, extension springs can work. But be ready for more frequent checks. DIY maintenance tips
Cost, lifespan, and safety trade-offs in Durham’s climate
In Durham, torsion springs cost $150–$300 to replace, while extension springs run $50–$150. Torsion springs last 10–15 years; extension springs last 5–7 years. Torsion springs are safer because they’re mounted above the door and don’t snap outward. Extension springs are exposed to weather, kids, and pets, increasing wear.

How to choose between torsion and extension for your Durham home
Start by checking your door’s hardware. If you see a metal tube above the door with springs inside, you have torsion. If you see springs on the sides stretching along the tracks, you have extension. Next, consider your door’s weight and age. Modern, heavier doors need torsion. Older, lightweight doors can use extension. Finally, think about safety and maintenance. If you have kids or pets, torsion is safer. If you’re on a tight budget and don’t mind more frequent checks, extension might work. Our full service list
Durham-specific spring replacement timing and local risks
In Durham, spring failure often happens after a harsh winter or a humid summer. If your door starts making loud noises or slows down, check the springs. Extension springs in older homes near the Eno River or downtown may corrode faster due to moisture. Torsion springs in newer builds in Hope Valley or South Ellerbe Creek neighborhoods last longer but still need lubrication twice a year. If you’re unsure, a licensed pro can inspect your setup and recommend the best fix. Areas we serve in Durham
When to call a pro vs. DIY spring replacement in Durham
Replacing torsion springs is dangerous and requires special tools—leave it to pros. Extension springs are simpler but still risky if mishandled. If your door is heavy or has a modern opener, torsion is the only safe choice. If you’re replacing extension springs in a lightweight door and have DIY experience, you can do it—but wear gloves and eye protection. Always disconnect the opener first. In Durham, a botched spring swap can damage your door or opener, leading to costlier repairs. Request a free estimate
Why torsion is the standard for most Durham garage doors today
Modern garage doors are heavier and require balanced lift. Torsion springs provide that balance, reducing strain on the opener and tracks. They’re safer, last longer, and perform better in Durham’s humid climate. Most new installations in neighborhoods like Hope Valley or Forest Hills use torsion springs. If you’re upgrading your door, torsion is the only practical choice. Extension springs are mostly found in older homes or budget setups. About our licensed team
Extension springs: a short-term fix with long-term risks
Extension springs are a quick, cheap fix for lightweight doors, but they wear out fast in Durham’s damp air. They’re also more dangerous—if one snaps, it can fly across the garage. If you’re in a rental property or a home you plan to sell soon, extension might make sense. But if you’re staying long-term, torsion is the smarter investment. The upfront cost is higher, but you’ll save on replacements and repairs. Durham’s trusted spring replacement service
