Torsion vs Extension Springs: What's on Your Garage Door?

If you own a home in Cypress, TX or anywhere in the NW Houston area, your garage door relies on one of two types of springs to open and close. Understanding the difference between torsion and extension springs helps you make smarter decisions when it's time for a repair or replacement.

Torsion Springs: The Modern Standard

Torsion springs are mounted on a metal shaft directly above the garage door opening. When the door closes, cables connected to the bottom corners wind the springs, storing energy. When you open the door, the springs unwind and release that energy to lift the heavy door panel.

• Location: Horizontally mounted above the door opening
• How they work: Twist (torque) to store and release energy
• Typical lifespan: 15,000–20,000 cycles for standard; 25,000+ for high-cycle
• Cost to replace: $200–$400 for a pair, installed

Torsion springs are the standard in most Cypress-area homes built after the 1990s. They provide smoother, more controlled operation and are generally safer because the spring stays on the shaft even if it breaks.

Extension Springs: The Older Design

Extension springs run along the horizontal tracks on both sides of the door. They stretch (extend) when the door closes, storing energy in the elongated coils. When the door opens, the springs contract to help lift the door.

• Location: Along the horizontal tracks on each side of the door
• How they work: Stretch and contract to store and release energy
• Typical lifespan: 10,000–15,000 cycles
• Cost to replace: $150–$300 for a pair, installed

Extension springs are common in older homes and lower-end installations. They're less expensive but have a shorter lifespan and pose a greater safety risk — if one breaks without a safety cable, it can fly across the garage with dangerous force.

Which Type Is Better?

Torsion springs win on almost every metric: they last longer, operate more smoothly, put less stress on the opener, and are safer if they fail. The only advantage of extension springs is their lower upfront cost. If your home currently has extension springs, we recommend upgrading to torsion when it's time for replacement.

How to Tell Which Type You Have

Stand inside your garage with the door closed and look up. If you see a thick coil mounted on a metal bar above the door, you have torsion springs. If you see springs running along the tracks on the sides of the door, those are extension springs. Still not sure? Snap a photo and text it to us at (281) 948-5452 — we'll identify it for you.

The Garage Goat Recommendation

We install high-cycle torsion springs rated for 25,000+ cycles on every job. They cost slightly more upfront but last 2–3 times longer than standard springs, saving you money over time. Every spring we install comes with a lifetime warranty.
