What is the difference between torsion and extension garage door springs?

Torsion springs mount horizontally above the garage door opening and use torque to lift the door. Extension springs run along the horizontal tracks on each side and stretch to provide lifting force. Torsion springs last longer (15,000–20,000 cycles vs. 8,000–10,000) and provide smoother operation.

What is the difference between torsion and extension garage door springs?

Torsion springs mount above the door on a metal shaft and use torque to lift the door. Extension springs mount on both sides of the door and stretch to provide lifting force. Torsion springs are safer, last longer, and provide smoother operation.

Which type of garage door spring is safer?

Torsion springs are significantly safer. When an extension spring breaks, it can fly across the garage at high speed causing injury or property damage. Torsion springs are contained on the shaft and do not launch when they break.

How long do torsion springs last vs extension springs?

Standard torsion springs last 15,000-20,000 cycles (7-12 years). Extension springs last 5,000-10,000 cycles (4-7 years). High-cycle torsion springs rated for 50,000+ cycles are available for high-use doors.

Can I convert my extension springs to torsion?

Yes. Converting from extension to torsion springs costs $350-$600 including hardware and labor. It is one of the best upgrades you can make for safety and performance.

How much does it cost to replace garage door springs in CT?

Torsion spring replacement costs $250-$475 in Connecticut. Extension spring replacement costs $150-$300 for a pair. Always replace both springs at the same time even if only one is broken.

Torsion Spring vs Extension Spring: Which Does Your Garage Door Use?

Q: Should I replace both garage door springs at the same time?

Yes. If one spring has broken, the other is the same age and will likely fail within weeks or months. Replacing both costs only marginally more since the labor is the same, and the second spring adds just $50 to $100 to the total job.

Q: Can I convert from extension springs to torsion springs?

Yes. The conversion involves removing the extension spring system and installing a torsion spring shaft, brackets, and spring above the door opening. The cost typically runs $300 to $550 and takes about two to three hours.

Torsion Springs vs. Extension Springs: Which Is Better?

In my professional experience, torsion springs are the better system for most homes. They provide smoother operation, last longer, and are generally safer. That said, extension springs still work perfectly well for lighter doors and can be a cost-effective option.

How Long Do Garage Door Springs Last in Connecticut?

Spring lifespan depends on cycles of use and environmental conditions. A standard torsion spring is rated for 15,000 to 20,000 cycles, roughly 7 to 12 years. Extension springs have a shorter lifespan of 8,000 to 10,000 cycles, or about 4 to 7 years. Connecticut’s climate adds extra stress on springs. I recommend annual lubrication with a silicone-based spray to extend spring life.

Can I Convert from Extension Springs to Torsion Springs?

Yes, converting from extension springs to torsion springs is possible on most garage doors. The total cost typically runs $300 to $550 and takes about two to three hours.

Frequently Asked Questions About Garage Door Springs

How do I know if my garage door spring is broken?

The most obvious sign is a loud bang from your garage. After a break, your door will feel extremely heavy. If your opener runs but the door barely moves, a broken spring is likely the cause.

Can I open my garage door with a broken spring?

Technically you can disengage the opener and lift manually, but I advise against it. A standard garage door weighs 150 to 250 pounds without spring support.

Should I replace both garage door springs at the same time?

Absolutely. The other spring is the same age and will likely fail within weeks or months. Replacing both costs only marginally more.
