Drywall Patching
Crocket told Cheapism about a job where an electrician had moved a few outlets in a home and left holes in the wall. The homeowner wasn’t able to find a drywaller willing to do such a small job, and the Crockets couldn’t paint until the holes were patched.
After a bit of studying and asking for help at the local hardware store, they were able to patch the holes themselves. It was easy enough that Crocket recommends that homeowners learn this skill as well.
