How can I tell if my garage door spring is broken and who should repair it?

A broken garage door spring is often noticeable right away. Many homeowners report hearing a loud popping sound in the garage when the spring breaks. You may also see a visible gap in the spring coil, and the door may suddenly become very heavy or refuse to open. In some cases, the opener will try to lift the door but struggle because the spring is no longer supporting the weight.

Because garage door springs operate under significant tension, they should only be replaced by a trained technician. Attempting to repair or replace a spring without the proper tools and experience can be dangerous. A professional can safely replace the spring, inspect the rest of the system, and make sure the door is operating properly again.
