Drywall Installation Cost

How much does it cost to install drywall in a single room?

Whether you call it sheet rock, wallboard, or drywall, it is a material that is used for most modern homes and buildings to serve as sturdy walls and ceilings. Installing this material can be somewhat difficult, and most homeowners don't view installing a full room of drywall as a DIY project.

For this discussion we will be considering the costs of installing drywall in a bedroom that is 12'x12' in size. Because the height of the room will also come into the equation we will use a ceiling height of 8' as our base as well.

The average costs and materials associated with a project like this would include:

  • The Drywall - The room described above is going to demand around 600 square feet of drywall to cover the walls and the ceilings. These will be sheets sized at 4'x8' and cost around $9 each. This means that roughly 20 sheets are required for this project, which will cost around $180 total.
  • The Materials - hanging drywall means the use of special 1 1/4" drywall screws. These are sold by the pound and contain around 300 screws in each pound. Most carpenters estimate that they will require roughly one pound for every 500 square feet of drywall installed. The average cost for a single pound is $6, which means that around two pounds will be necessary for the project, at a cost of $12. There is also the need for specialty "tape" and the joint compound or "mud" required to complete the job. Most carpenters apply a unique mathematical formula to their work, with most dividing the square footage of the space by 7.25 to determine the number of pounds of mud to buy. For this example we would end up with the need for around 85 pounds, or two 45 pound pails that cost around $14 each. Lastly, the tape used to cover the joints between the sheet rock costs only $4.50 for every 150 feet, and a single roll should complete this project; and
  • The Labor - At HouseFlippingHelper.com it states that the homeowner who pays roughly $25 in total costs per sheet of drywall is getting a cheaper price. This means that around 50% of a drywall project is going to be directed at the labor, and the site goes on to state that most consumers can expect to pay more than that with average per sheet prices around $30 each. It is extremely important to sit down with the contractor selected for the project and to work out each item that will be completed, and the exact costs for them. Asking for a few quotes and demanding proof of insurance is perfectly acceptable as well.

Additional considerations and costs

  • Clean up - it is vitally important that the homeowner establish the fact that the contractor is going to provide a comprehensive cleanup at the site. There are many stories of homeowners left with dust and debris all over their homes, and this is something that is easily avoided through honest negotiation and discussion before beginning the work.
