DIY Build a Frame Around a Duct
- 1). Measure the ductwork with a measuring tape.
- 2). Add one-half inch to each of the measurements around the ductwork. This will allow the ductwork to expand and contract in the frame.
- 3). Cut a 2-by-4-inch stud to run the length of the soffit. U-shaped soffits will need two studs for either side of the duct. Use the measurements from the ductwork to mark the studs and then cut the studs to size with a miter saw.
- 4). Screw the 2-by-4-inch board(s) into the ceiling joists with a screwdriver. Place the board(s) one-half inch away from the ductwork. Screw the board(s) in place.
- 5). Build the frame for the ductwork by creating U or L-shaped frame pieces out of 2-by-4-inch boards. Use the measurements of the ductwork to get the correct measurements for the height and width of the frame. Cut the pieces to size on a miter saw. Screw the pieces together with screws and a screwdriver. The U-shaped or L-shaped pieces should fit over the ductwork every 16 inches on center.
- 6). Hold a U-shaped or L-shaped piece in place over the ductwork. Place a level against the board to ensure that it is level. Screw into place on the 2-by-4-inch board(s).
- 7). Install drywall over the frame per manufacturer's directions and paint to match the room.
