I was skeptical, I will admit. Now that my job is done, I must sing the praises of this company and their employees... I have an old house and have had many issues of various kinds over the years. I knew the sewer line would be a major problem. I did my research, and decided on Benjamin Franklin MD to do the work needed. I was not disappointed. As a matter of fact, it I could sing their praises on-line...anywhere....I would, Professional...kind...respectful. GLADLY recommend.
