If you're like most people, your garage door is your primary entrance to your home. It's convenient to use and parking in the garage provides protection from the elements. Garage doors have several moving parts, including the door springs that help raise and lower the door. These springs do eventually break down, leaving the door inoperable. When this happens, it's time to repair or replace the damaged parts. This cost guide shows you what it costs to hire a professional to repair or replace any garage door spring.
In most cases, only one spring breaks or wears out at a time, and you can get away with replacing just the failed spring. But this is a little like replacing old car tires one at a time. You'll get the best performance if all the springs are new and have the same strength. Extension springs are replaced individually, making it more tempting to replace just one. With torsion springs, you have to disassemble everything to replace either spring, so it makes sense to swap out both springs during the repair.
