If you have a damaged piece of drywall in your home, calling a contractor to do a repair is desired. However, the job can be done on your own if you have the proper tools and some basic knowledge about repairing walls. Here are some instructions to follow when replacing a damaged portion of your wall on your own. 

Marking The Area

Draw a rectangle around the broken portion in your drywall. Peek inside the hole in the drywall to see if there are any wires or other obstructions in the way before cutting along the line you had drawn using a drywall saw. Remove the drywall so you are left with a rectangular opening. 

Preparing The New Piece

Measure the thickness of your existing drywall and head to your local hardware store to pick up a new piece. Measure the hole you had just cut from your existing drywall as you may be able to purchase a piece of scrap drywall rather than an entire sheet. Slide a piece of plywood that is about two inches longer than the hole inside the opening of the hole. Position it so an inch is above the top of the hole and an inch is below the bottom of the hole. The width of the plywood needs to only be an inch or two as it will be used to stabilize the new piece of drywall. 

Place another piece of plywood on the other side of the hole in the same manner. Use glue attach these plywood pieces to the underside of the existing drywall. Screw the plywood pieces into place from the exterior. These screw holes will be covered with compound when you patch the wall. Push the newly cut piece of drywall into the rectangular cutout and use drywall screws to attach it to the plywood pieces.

Patching The Wall

After the new piece of drywall is screwed into place, you will want to cover it so it is not seen. Spread drywall compound over the edges of the new piece of drywall. Push a piece of drywall tape over the seam, using the compound to seal it into place. Cover the paper with another layer of compound. Use a putty knife to spread it smoothly over the area. 

If your hole was located on a corner, you may need to add a piece of drywall trim to help stabilize the new drywall. Patch over the trim using the compound to cover the metal or plastic from view. Do the same with the screw heads. Allow the compound to dry completely and add two more coatings, allowing to dry between each. This helps to harden the wall so the new piece of drywall will not become dislodged if pressure is applied. After the compound hardens, use sandpaper to smooth out the rough edges left behind. Add a new coating of paint to hide the repair work completely.
