The tech, Will, arrived in the time frame that was stated in my call for service. He was courteous and friendly and easy to work with. He did an excellent job in a difficult circumstance that required clearing a 120 ft sewer line with the only access being from the roof (flat roof). The 120 ft snake cleared the block. Then using a line camera a pipe break was found which had created a smaller area for waste passage and had become blocked. Other work was done, too, and all was in good order when Will was finished. Will knew what he was doing and he did it well. Very satisfied with the work done.
