"Sewer pipe lining project on a 100 year old house made easy! Communication was excellent and there was very minimal disruption to us. The pricing was reasonable compared to other quotes. I would highly recommend using Bob Oates for any plumbing projects."

Modern trenchless technology, decades of hands-on field experience.
When your sewer line fails, you need a team that knows how to diagnose, clean, and repair the problem quickly.
The Sewer Repair Process
Finding the Source
A high-definition camera runs from the cleanout to the city main, so we see cracks, root intrusion, and offset joints in real time — then explain exactly what's wrong and the best path forward. No digging to diagnose.
Thorough Cleaning & Prep
Sewer cleaning isn't drain snaking. Rotating cutters clear root masses and hydro jetting scours the pipe walls, so repairs bond correctly. Sometimes a deep cleaning resolves the issue outright.
Trenchless Solutions
Whenever possible, we repair from the inside — no digging up your yard. UV-cured CIPP lining or pipe bursting restore flow fast, often in a day: the no-dig, cost-effective, environmentally friendly fix.
Pipe Replacement
When damage is too severe for trenchless — collapsed pipe, extreme offsets — we excavate with precision, replace with Schedule 40 PVC, restore the area, and confirm flow with a post-repair camera inspection.
