Can You Replace a Garage Door Spring Yourself?
The short answer is that you should not. A broken garage door spring is one of the more dangerous home repairs. This guide explains why. It also lists what you can safely do while you wait for help.
Why springs are dangerous
A garage door spring stores a large amount of energy. A torsion spring sits above the door and is wound tight. An extension spring stretches along the track. Both can release that energy suddenly. Repair work uses proper winding bars and exact steps. A slipped tool can cause serious injury. Read torsion vs extension springs to see which type you have.
It is not only about injury
A spring must match the door. The right size depends on the weight of the door and its height. A spring that is too weak or too strong leaves the door out of balance. That strains the opener and wears other parts. See what a balance problem looks like.
A broken spring often means the other spring is the same age. Many technicians replace both. Read whether to replace one spring or both.
What you can safely do
