I had this company come out and pressure wash my gas pump area concrete and parking lot. They did an excellent job removing oil stains and cleaning up the area. The concrete looks like it was just recently finished although it has been there for 3 years. The owner came in when they were finished and asked me to walk around outside with him and inspect the work that they had completed. Needless to say I would definately recommend this company to anyone looking for a fresh clean look for your business.
