Im considering doing this work myself, however, after having done some stucco repairs in the past, Im wondering how to patch the 3-4" diameter hole that remains in my stucco after Im done. Since the hole is round (I assume), do I just mold up some stucco chicken wire and put it in each hole and stucco it up? How about the paper/tar vapor seal that is broken during the drilling?
Also, what's the best way to create the holes? Air chisel? Some-type of massive drill bit?
