Garage door springs are under enormous tension and counterbalance hundreds of pounds every day. Understanding how they work — and how they fail — keeps you safe and saves you money. Homeowners across Saint Peters, MO trust us for honest, same-day service — (636) 352-0935.
If your door has two springs and one broke, replace both. They share the same cycle life, so the second is right behind the first, and doing both at once saves a second service call. A good technician also checks the cables and bearings while they are there.
A two-to-three-inch gap in the coil, a door that opens a few inches then stops, an opener that strains or reverses, or a door that feels like dead weight by hand all point to a spring. You don't always hear the bang.
Most modern doors use torsion springs mounted on a shaft above the opening; older or lighter doors use extension springs along the tracks. As the door closes the springs wind and store energy, then release it to lift the door. That stored energy is what makes a heavy door feel light.
Springs are rated in cycles — one up-and-down is a cycle, and a standard spring lasts about 10,000 of them, or 7-10 years for a typical family. Rust from {state} humidity, cold snaps that make steel brittle, poor balance, and undersized springs all shorten that life.
Torsion springs hold tremendous stored energy and the winding bars can become projectiles if they slip — every year emergency rooms see DIY spring injuries. A trained technician has the right winding bars and the correctly sized spring and finishes the job safely in under an hour.
Can I replace a garage door spring myself?
It is strongly discouraged. The springs are under high tension and can cause serious injury. This is one repair that should always be left to a trained professional.
How long do garage door springs last?
A standard spring is rated for about 10,000 cycles — roughly 7-10 years of normal use. High-cycle springs rated for 20,000+ cycles last much longer and are worth it for busy households.
