Cleared our blockage without noise, fuss or mess, unlike the other guy we'd been using for years. Even explained why our blockage had occurred, which was a mystery to us, since we have the line rootered every year as preventive maintenance, and were not due for another service yet. (While maple-tree roots are our normal sewer-line problem, RRN explained that recent road work in front of our house had probably vibrated the sewer line and caused old corrosion to break loose and block the line). His bill was 25% lower than the other guy, too, so we'll be calling RRN from now on. Really happy to have found this company.
