Sewer line replacements and sewer line repairs require precision, advanced equipment, and a great deal of experience. Sewer installations and repairs are a specialty trade that does not fall within the normal scope of work for the average “plumber”. In order to obtain the required permits for a subsurface sewer replacement, the contractor must hold a Master Plumbers license, sufficient insurance coverage, and a specialty bond with the local DOT. A broken sewer line can be messy, disruptive, and even hazardous to the health of your family, customers, or employees.
