Questions to ask a sewer contractor
A first call should clarify ownership, diagnosis, method choices, permits, restoration, and warranty, not just a same-day price.
Ownership and access
Ask where the property-line, cleanout, or main-connection boundary is for your city, and who opens public right-of-way if needed. That answer decides who pays and who pulls the permit.
Shared laterals on older lots and multifamily buildings can split responsibility. If more than one house sits on the line, get the recorded arrangement before you authorize a full replacement.
Evidence and method
Request the recording, a defect map, and at least one alternative method with reasons it was rejected. A contractor who only sells lining, or only sells digging, still needs to explain why the other path fails here.
Drain cleaning, camera work, and structural repair are not the same product. Confirm which one you are buying today, and whether the same company will do the follow-on work.
Money and risk
Confirm permit puller, inspection timing, restoration limits, change-order triggers, and what voids the warranty. Ask for the legal entity on the contract and proof of license and insurance for that entity, not a trade name on a truck.
Directory inclusion here means website signal of sewer work. It is not a license verification or an endorsement. Those checks are still yours.

Common questions
- What is the most important first question?
- Who owns the section that failed (homeowner lateral, shared line, or municipal main), and how will that be confirmed?
- Should I hire the first crew that clears the backup?
- Clearing and structural repair can be different companies. Keep the camera file and get a written repair scope before authorizing major work.
- What red flags show up on a first call?
- A same-day replacement price with no camera file, a refusal to name the method, or a contract that leaves restoration and permits as “to be determined.”
