I was very pleased with Roto-Rooter. Our sewer backed up and we gave them a call and they were here within the hour. The service tech was extremely nice and friendly. He worked quickly, but did a thorough job. Also, he took extra care not to track mud into the house or drag his machine on the floor. The problem got fixed and the work is guaranteed for 6 months. We even got to use a coupon. I would highly recommend them for the quality of their work, timeliness, and great customer service.
