I accidently grabbed onto my towel rack when trying to change a light blub, and it yanked the anchors out of the wall leaving a mess. Being fairly new with home repair, what is the best method for fixing this issue? What tools would be needed? If it's not too difficult, I could do it myself and not call a contractor out.
Ideally the screws should be into a stud, but this is not always possible.
Here is a possible solution. Use a drywall knife to cut out the damaged piece of drywall. I would stay inside the mark left by the bracket.
Use a piece of board a little narrower than the opening and about 4" longer than the opening. So if the opening is 2" you would make the piece 6" long. You will be slipping this into the opening.
Start a screw into the piece of wood 2" down from 1 edge and apply construction adhesive to 2" area on both ends. Slip the piece into hole using the screw as a handle. Once you get the piece in the wall start another screw at center for handle and remove the first screw. Center the piece in the opening.
Use another piece of wood 6" long about 1" wide and insert a screw through a pre-drilled hole into back piece and tighten while holding the back piece in place using your screw handle. This will create a wedge to hold the back piece till the adhesive dries.
Allow this to set about a day before removing wedge.
Fill the hole with a piece of drywall and touch up with spackle if necessary.
