I recently hired a guy to come stain the concrete in my home. He runs a small business here that does that. Long story short he did a HORRIBLE job. Not the color I asked for, rocks and grass sealed in, stain on the walls and baseboards, and a very uneven job. He was supposed to come fix it but I am pretty sure he saw what he had done and is avoiding me now. I paid him half the cost up front and would really like some of my money back and also make sure he does not do this to anyone else. Can anyone offer advise of what I can do?
