Choosing a qualified contractor or learning how to hang drywall yourself begins with an understanding of the different types of drywall available, the many factors that affect the overall cost of drywall, and the supplies needed to install it. Some costs are obvious, such as the ones for panels, screws, tape, mud, and joint compound, but other components, such as demolition, transportation, permits, and even the volume of sandpaper you’ll need to get the job done well, might escape notice.
