While some garage door problems can be fixed by a single person, the heavy weight of garage doors might demand extra help. If a panel needs to be replaced, a second set of hands is almost certainly necessary.
Other problems with garage doors are fairly simple to fix, and regular tune-ups can help prevent future problems. In addition, newer garage doors use electrical components that wear down over time; owners with experience working with electronic parts can often fix their own problems. However, it's important to exercise caution when working on a garage door as the large current they pull can be dangerous and potentially fatal, as can a falling garage door.
