Billy did an exceptional job with this difficult task. We wanted to put in a dog door, so we had him cut a hole in our 10" concrete block wall. Not only did he bid a very reasonable price (especially compared to the others we received), but he had the tools to take care of everything, even the unknown (there were 2 thick bars of rebar that he had to cut out as well). Billy was professional, timely, and courteous. He made sure we were completely happy with his work and cleaned up the debris before he left. We highly recommend him for any task you may have--he is awesome! Thanks, Billy!
