Most of a sewer repair ends up buried. Once the trench is filled or the liner is cured, you depend on the paperwork, the permit inspection and the final camera video to know what was done. That makes the hiring step the moment to be careful.

Work down this list for each contractor you are considering. None of it requires special knowledge, and a contractor who is comfortable with these questions is usually comfortable being held to the answers.

License and identity

  • Get the CSLB license number in writing, along with the company name.
  • Look it up at cslb.ca.gov and confirm the license is active.
  • Check that the business name on the license matches the name on the contract.
  • Ask whether the people doing the work are employees or subcontractors.
  • Ask who will be on site as the person in charge each day.

The work itself

  • The method is named and explained against your camera footage.
  • The start and end points and the length of pipe are in writing.
  • Pipe or liner type and size are stated.
  • Who obtains the permit and arranges inspection is in writing.
  • Surface restoration is listed item by item.
  • A camera inspection after the work, with the video handed over, is included.

Money and paperwork

  • The contract is in writing and signed before work starts.
  • The payment schedule ties payments to completed stages.
  • The down payment follows California rules; the CSLB site explains them.
  • Change orders must be in writing and signed by you.
  • You receive copies of the permit, inspection sign-off and invoice at the end.

Warning signs during hiring

  • IfNo license number offered, or it does not check outThenDo not proceed.
  • IfPressure to sign the same day for a non-emergency jobThenTake time to get another quote.
  • IfSuggestion to skip the permitThenTreat as a serious concern.
  • IfRefusal to show or share the camera footageThenAsk why; a second opinion may help.
  • IfLarge cash payment requested up frontThenCheck the CSLB rules and reconsider.

Common questions

Is a business license the same as a CSLB license?

No. A city business license lets a company operate; the CSLB contractor license is the state license for construction work. Check the CSLB license at cslb.ca.gov.

What if it is an emergency backup at night?

Clearing a line can be done quickly, but you can still ask for the license number and decline to sign for a full replacement on the spot.

Should I ask for references?

It is reasonable to ask. Also check the CSLB lookup, which shows license status.
