Chapter 06 — Questions

Frequently asked.

What is trenchless sewer repair?

Repairing a sewer line without digging a trench. Cured-in-place lining forms a new pipe inside the old one; pipe bursting pulls a new pipe through while breaking the old one apart. No torn-up yard, most jobs done in a day, and the result lasts 50+ years.

How much does sewer repair cost in Seattle?

We quote from camera footage, not over the phone. Camera inspection is free with sewer cleaning. Trenchless usually costs less overall than dig-and-replace once you count excavation and landscape restoration. Written estimate before we start; free second opinions on other written bids.

Is Bob Oates a licensed side sewer contractor?

Yes — a Registered Side Sewer Contractor (RSSC) with the City of Seattle. The certification required for side sewer work here. Always ask bidders for their RSSC number.

Do you offer emergency service?

Yes — 24/7, 365 days a year. Call (206) 789-4944; a real technician answers.

Is the 20-year warranty really transferable?

Yes. Our sewer work carries a 20-year warranty written into your contract, and it transfers to the next owner if you sell the house.
