Garage Door Cable Safety Explained

Springs do roughly 90% of the work of lifting a garage door — the opener just guides it. When a spring breaks, the whole system stops working safely, which is why it is the single most common garage door failure in Edison. Homeowners across Edison, NJ trust us for honest, same-day service — (732) 454-3538.

Torsion vs. Extension Springs

Torsion springs sit on a bar above the door, last longer, and balance the door more smoothly — the modern standard. Extension springs run along the horizontal tracks and should always have a safety cable so broken pieces can't fly. Knowing which you have helps describe the problem.

Replace One Spring or Both?

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.

The Warning Signs

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.

Why Spring Work Is Not DIY

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.

How Garage Door Springs Work

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.

Edison Garage Door FAQs

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.

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.
