Review by: Rich N. in Frazier Park, CA Project: Clean Up Job-site after Construction One Step was brought out to provide a quotation to perform construction cleaning for a two large government projects we were completing in King City, CA and Frazier Park, CA. Their owner met with me directly, reviewed the scope of work and provided a detailed proposal. Once they began work, they showed up when they said they would, and they completed their work in a thorough and professional manner. We were very satisfied with their work and customer service.
