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.

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.

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.

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.

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.

Hightstown Garage Door FAQs

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.

Why did my spring break in the cold?
Cold makes steel more brittle, so a spring already near the end of its life often snaps on the first freezing morning. It is one of the most common service calls we get each winter.
