Of course, you can. Painting your garage door is a DIY project that you can safely undertake yourself. You do not need a Rosemount garage door repair technician to help you do that. All you have to do is know the type of garage door you have and what type of paint or stain would adhere quickly to it. We have steel doors, wooden doors, fiberglass, and all these doors are made from completely different materials so paints would adhere differently to them.
