Bill from Roto-Rooter did an exemplary job for us when the main line backed up. We called Wednesday night and he came from 6-10, was back again from 8:00-10 the next day, and once more the following day from 7:30-9. He got the job done and made excellent recommendations. He really wanted to solve the problem, not just get on to the next job. Would call him first again no question, but feel confident I won't have to call anyone for a long time after this fix!
