"Owner came out promptly when we called for a sewer line backing up into our basement. His quote was better than another we received an hour before, and he had the equipment ready to go immediately. He cleared the blockage and advised us to pursue a video inspection because of a snag in the line (possible rupture in the pipe and/or tree root) that likely contributed to the backup."
