Why homeowners call back

One licensed plumber. Yours for the whole job.

Anderson Sewer and Rooter is registered with the state as a sole ownership, and the license carries a workers’ compensation exemption because there are no employees. In plain English: there is one plumber, and he is the owner. Nobody hands your job to whoever is free that afternoon.

That shows up in the reviews. Customers from 2023 through 2026 name Sam personally — same plumber, same standard, three years apart.
