The average price for Sheetrock, also known as drywall, installation is about $713.12 for a low-quality job or $878.39 for a higher-quality job, as of 2015, notes Homewyse.com. The actual cost of the drywall is about $217.25 to $249.95 for a 535-square foot room, while the labor runs from $439.00 to $559.94 for six hours.
Another factor that goes into the cost for installation of Sheetrock is additional parts, such as fasteners, seam tape, outside corner beads and topping compound. For most jobs, this only adds about $25 to the total price of the project. Because the project is messy, a homeowner can also factor in the cost of paying a crew for cleanup.
