DIY steps
- Turn off applicable nearby circuits, clear the area, and wear a dust mask, safety glasses, and gloves. Before cutting, scan for concealed wiring and plumbing; drywall itself is not load-bearing, but do not cut structural framing or an area with detected utilities.
- Cut a wood furring strip to fit behind the damaged area, leaving about 1/2 inch of extra length on each side. Hold the strip in place and use a level to ensure it's straight, then mark the drywall with a pencil.
- Use a drywall saw to cut out the damaged area, following the marked lines. Remove the damaged drywall, taking care not to gouge the surrounding area. Use a putty knife to scrape away any remaining debris or old joint compound.
- Hold the furring strip in place and use drywall screws to secure it to the surrounding drywall. Make sure the screws are countersunk so they won't interfere with the new drywall patch.
- Cut a drywall scrap to fit within the opening with an approximately 1/8-inch gap around its edges. Use drywall screws to secure the patch to the furring strip, spacing them about 6 inches apart.
- Apply joint compound and drywall tape to the patch seams, then feather compound toward the surrounding drywall. Allow each coat to dry completely according to the manufacturer's instructions before sanding it smooth.
- Use a sanding block to sand the entire area smooth, feathering the edges of the patch out towards the surrounding drywall. Wipe away any dust or debris with a damp cloth, and apply a second coat of joint compound if necessary.
