We clean the existing pipe with hydro jetting to remove roots, debris, and buildup. The pipe interior must be clean for the liner to bond properly.

Scranton Sewer Authority verifies every trenchless repair in Derry with a post-installation camera inspection. We document the completed work and provide you with before-and-after footage proving the repair quality.
Common questions about trenchless sewer repair in Derry.
Trenchless sewer repair in Derry typically costs $4,000 to $12,000 depending on pipe length, diameter, and damage extent. While the repair itself may cost more than excavation, total project cost is often lower because you avoid landscaping, driveway, and hardscape restoration.

Yes. CIPP liners and burst-in HDPE pipe are rated for 50+ years of service. The seamless liner is actually more resistant to root intrusion than traditional jointed pipe because it has no joints for roots to enter. Scranton Sewer Authority warranties trenchless repairs in Derry.
Most can, but not all. Severely collapsed pipes, pipes with multiple sharp bends, or undersized pipes may not be candidates. Scranton Sewer Authority always camera-inspects first and is honest about when trenchless is and is not the right choice for your Derry property.
Honest reviews from property owners who chose Scranton Sewer Authority for their sewer and drain needs.
"Our sewer line bellied in two places causing constant slow drainage. They identified both locations with the camera and repaired them with targeted excavation. Minimal yard disruption for a tough repair. Well done."
"They replaced our old cast iron drain pipes with PVC. The work was clean, finished on time, and the price was exactly what they quoted. No hidden costs. Highly recommend."
"Toilet was overflowing and nothing we tried would fix it. The technician discovered the problem was actually a clog in the main sewer line, not the toilet. He had it cleared in less than an hour. Knowledgeable crew."
