A clear, professional approach to trenchless sewer repair — tailored to your Portsmouth property.
Scranton Sewer Authority assesses your Portsmouth, NH sewer line with camera technology to determine the best trenchless approach — CIPP lining for cracked and root-damaged pipes, or pipe bursting for collapsed sections.
Our Portsmouth technicians prepare the pipe by jetting it clean and removing any obstructions. Proper preparation is critical to the success and longevity of a trenchless repair.
For CIPP lining, we pull a resin-saturated liner through the pipe and cure it in place with steam or UV light. For pipe bursting, we pull a new pipe through while simultaneously breaking the old one apart.
Scranton Sewer Authority verifies every trenchless repair in Portsmouth with a post-installation camera inspection. We document the completed work and provide you with before-and-after footage proving the repair quality.
