How To Install Drywall Around Ductwork

There are many ways to approach the task of installing drywall around duct work. Begin the project by making sure you have the right tools for the job.

Required Tools

  • Ladder
  • Pencils
  • Drywall sheets
  • 24-inch drywall cutter
  • Measurement tape
  • Utility knife
  • Drill machine with drywall tip attachment
  • 11/2-inch drywall screws

Once you have collected the required tools, we are ready to get started. But wait! This is not exactly a one-person job. Better find an extra set of competent hands attached to an able body to assist.

Step 1: Measure the Amount of Drywall

This is no time for guesswork. Break out the measuring tape and calculate how much drywall you will need to complete this project. Be sure you have assistance in making these precise calculations.

You can also frame the ductwork first and then place the drywall around that. Use a sheet to make the markings for the measurements. Take note of all the measurements you make.

Step 2: Create A Rectangular Area

Locate a control point on the ceiling joist to one side of the duct. Measure the edges from the center of the stud. You will also need the measurements for the opposite edges. With these measurements, you will be able to create a rectangular area in the space of the duct. This area will have to be cut out so that it fits around the duct. Measure from the edge of the drywall and mark off these points. Most often the measurements of this rectangular area will be 8” X12”.

Step 3: Cut the Drywall

Mark the outline of the rectangle on the drywall. Once it is marked, use the 24” drywall cutter. You must cut the drywall sheet. Use the utility knife to get these edges perfect. Pull the rectangle section from the sheet.

Step 4: Drill It with Drywall Tip Attachment

Now take out the drill and attach the drywall attachment to the end. Position the sheet of drywall against the wall and be sure to connect with the controlled edge of the stud. Drill the sheets to align with the edges of the rectangle of the duct. Use the 1.5” screws to connect the drywall. Make sure that you have maintained the 6-inches distance between the drywall and the ductwork.

Before the task is complete, you will need to check for leaks in the duct work that could cause inefficiencies in the system.

And those are the steps you will follow to apply drywall to the ductwork.
