Garage Door Spring Types in Simi Valley: Torsion vs. Extension Explained
2026-08-18 7 min read
Most people don't think about their garage door until something breaks. When it does, you're standing there wondering whether you have torsion or extension springs and why it matters. The answer is straightforward: your spring type determines how your door opens, how long repairs take, and what you'll pay for them.
Torsion Springs: The Standard (and Safer) Choice
Torsion springs sit above your garage door opening, mounted on a metal shaft. They work by twisting and storing energy as your door closes. When you press the opener button, that stored energy helps lift the heavy door with minimal effort from the motor. See our guide on garage door won.
Here's what matters: torsion springs are the safer option. They're enclosed above the door, so they can't snap and whip across your garage. They also last longer, typically 7 to 9 years with normal use, compared to 5 to 7 years for extension springs. If you have a heavier insulated door or open and close frequently, torsion is what you want.
One torsion spring usually handles your entire door weight. That means when it fails, your door won't open at all. No gradual decline. It just stops working. That's why same-day service matters in Simi Valley. Read about roll-up commercial garage doors for warehouses in simi valley.
Extension Springs: The Budget Alternative
Extension springs run horizontally along each side of your door frame, above the tracks. They stretch and contract as the door moves, providing counterbalance force. They're less expensive upfront and take up less headroom in tight spaces.
The catch? Extension springs are exposed. If one snaps, the metal can fly across your garage with serious force. They also require safety cables running through the center to contain any breakage. Most homes need two extension springs working in tandem, so if one fails, the door becomes unbalanced and operates unevenly.
Extension springs are fine for lighter doors or occasional use, but they demand more frequent inspection and maintenance.

How Springs Fail (And Why It Happens)

A snapped spring usually shows one clear sign: your door feels heavier than normal or won't open at all. Some people try to force the opener, which can damage the motor. Don't do that.
