People sometimes use the terms “sheetrock” and “drywall” interchangeably, but they are not exactly the same. Drywall is the industry term for prefabricated sheets of wall, while Sheetrock is the brand name of a type of drywall. Depending on what room is being built, your drywall installation pro will select different thicknesses or grades of drywall. Standard residential drywall is ½-inch thick. Garage walls adjacent to a living space are typically ⅝-inch thick and serve as a firewall. For a garage ceiling, most contractors will use firewall-grade drywall materials to keep your home as safe as possible.

Different types of drywall can be color-coded to indicate their purpose. Purple or green drywall boards are often mold-resistant (MR) and are applied where moisture tends to accumulate, such as in bathrooms and basements or behind tile backsplashes at sinks. These mold-resistant sheets have a fiberglass instead of a paper facing finish to prevent water absorption. Regular drywall is gray or white. The drywall industry is constantly adapting with technology to provide safer and more targeted materials. You can even install soundproofing drywall to help prevent noise transfer through rooms.

The national average cost to hire a drywall installation professional ranges $375-$1,500, depending on the job at hand and where you are in the country. Your drywall installation cost will often be lower if the professional is installing the drywall in a new construction with open access as opposed to a remodel. The square footage of the job, the amount of materials, and the labor required also determine drywall prices. According to drywall pros, materials costs can range from 15 percent to 50 percent of your total project cost, depending on the work you’re having done. Request several quotes from drywall installation companies to find the right fit for your construction project. The quotes may be based on the company’s standard cost per square foot or a calculation of the time estimated to complete the job plus the size of the job plus materials and any travel fees. For example, drywall installation for one or two standard-size rooms could cost $900-$1,500. The cost to hang and tape an outbuilding with approximately 40 drywall sheets at 75 cents per square foot could total $1,450, including 3.75 days of labor for the drywall crew.

The national average price range to repair drywall is $210-$300. Drywall prices can vary greatly depending on the size of the hole or crack that needs repair, the amount of materials required, and other factors. Cracks can appear at the seams in your drywall due to uncontrollable factors like your house settling or even minor earthquakes. Drywall, although sturdy, will break with enough impact, so if a dresser falls and crashes into a wall or your have a mishap hammering in nails for artwork, you could need drywall repair. Drywall repair professionals may have a minimum service fee of $100-$150 regardless of the size of the job. This ensures that their business expenses are met anytime they send their crew out to a job. Here are some additional examples of average drywall repair prices:

• Repair a 4x8 section of wall: $225 (labor $150 and materials $75).
