Sewer Repair West Chester. A West Chester main sewer line needed to be repaired from a bad break causing mass root growth and backups for the homeowners in the area. The roots had been removed but kept coming back even stronger and potentially causing damage to other areas of the main sewer line. A local Perma-Liner installer was called out to install a Sectional Point Repair over the break. Within three hours, the section of the main sewer had been repaired and given another 50+ years of life! If you live in West Chester or a neighboring Philadelphia area, please call us to set up a live demonstration on sewer repair techniques using the Perma-Liner products.
