Repairing large holes in the walls

Fix the holes in the walls yourself by following these four steps.

Difficulty level : 
Duration : 
2 days

1
Cutting the damaged section

  • 1.1 Using a stud finder, locate the studs on either side of the hole.
  • 1.2 Using a square, outline a rectangle around the whole. The size depends on how big the hole is.
  • 1.3 Cut around the outline with a utility knife.
  • 1.4 Remove the section.

Using the square as a ruler ensures a straight line without having to change tools.

2
Reinforcing the sides

  • 2.1 Cut 2 reinforcement pieces. They should be 4 to 5 inches longer than the cutout. If there are no studs in the area, cut 2 support boards using at least ½" wood.
  • 2.2 Place the first reinforcement piece in the hole and hold it in place. Put the board at the top of the cutout so it’s half hidden by the panel.
  • 2.3 Screw the beam at the top and bottom of the cutout using 2½" drywall screws. The screws should be placed at an angle.
  • 2.4 Secure the second beam the same way.

Top tip

If your studs are more than 16" apart, cut the wall and support beams to fit the measurements.

3
Filling the hole with a piece of drywall

  • 3.1 With a utility knife and a square, cut a piece of drywall with the same dimensions as the cutout.
  • 3.2 Place the drywall in the hole and screw each corner to solidify.

Top tip

If the cut piece of drywall doesn’t fit into the hole, shave the sides until it fits properly.

4
Finishing the repair

  • 4.1 Cover the sides of the patch with drywall compound. If the gap around the drywall is too big, use joint tape.
  • 4.2 Apply a coat of drywall compound onto the joint tape. Let dry overnight, sand, and apply a second coat.
  • 4.3 Sand the joint with a medium grain sandpaper, repaint the wall if needed.
