I recently had a very bad experience with a flooring guy who I trusted for many years.
He had done great work for us in the past. He said he could level our basement floor and do a polished concrete floor. Well, the floor is not level and it is breaking apart. the more and more I get advice and talk to other professionals, it is clear that he did a terrible job, used the wrong materials and has no liability insurance. He said he would demo the floor, but he will not give us our money back. Any advice?
