Recent Review: Robert and his workers showed up when promised. They finished the job even a day or two before they promised. Robert's flexibility in dealing with the county requirements due to the location of my leach lines really impressed me. He uses high quality materials and workers. I would highly recommend Mayer and Sons for any work in the Phoenix Area or up on the Mongollon Rim. If you want high quality work done when promised, this is your company. I have great photos. Wish I could post them here to illustrate the quality and detail work.
