In the home improvement world there's a common recommendation regarding garage door spring repair: always leave it to the pros. Some springs for the old wood doors are still sold in hardware stores. The only problem with that is getting the right spring size, then having to put it on. The other new types of roll-up doors have a spring design that is very dangerous and should only be serviced by a trained professional. After all, if a spring breaks, isn't it about time to have the whole door checked out by a professional? Click Here for More Info
Can I change a broken garage door spring myself?
Yes! You can, but it is not advised because it's not as hard-and-fast as most sources claim. The procedures are pretty simple, but they involve many steps that must be done in the proper order, just like the pros do it. The spring is potentially dangerous until it is fully unwound. By contrast, extension springs have little or no tension when the garage door is fully open.
Professionals can replace broken garage door spring in an hour or two. When you hire a pro, make sure to ask about the quality of the springs they will install. They may well offer several grades of springs to choose from, at a range of costs.
