Here is how we handle every trenchless sewer repair project in Seattle.
We camera-inspect the damaged sewer line to determine if trenchless repair is feasible. We evaluate pipe material, diameter, damage type, and access conditions.

Our Seattle crew installs the trenchless repair using CIPP lining or pipe bursting — whichever method best suits your pipe condition and site requirements. Most installations are completed in a single day.
We camera-inspect the completed repair to verify the liner is properly cured and the pipe is structurally sound with full flow restored. You see the results in HD footage.
Common questions about trenchless sewer repair in Seattle.
Trenchless sewer repair in Seattle 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 Seattle.
