- With a tape measure, measure the area that will need to be covered, climbing a ladder if necessary. Write down the measurements so that a framework can be built around the duct work with 2-by-4-inch lumber. Cut lumber to size using a circular saw and begin building the frame, leaving 1 inch between the frame and the duct work to allow for expansion.
- Begin the frame off of a stud from another wall and carefully work around the duct work. Build around the entire area until the duct work is surrounded by a frame. Measure to make sure there is only 1 inch separating the duct work from the back of the frame.
- Cut the drywall to size with a utility knife so that it can be attached to the studs of the frame. Score the drywall using a T-square and line it up to the frame. Drill it in place with drywall screws every 16 inches down the entire frame.
- Connect drywall to each stud all the way around the frame until the duct work has been completely covered. Look over the drywall to make sure there are no gaps.
- Use a vacuum to clean up any dust and debris that remains from the drywall and lumber.
