License and identity

  • I have the contractor's CSLB license number in writing
  • I looked it up at cslb.ca.gov and the license is active
  • The name on the license matches the name on the estimate
  • I know whether employees or subcontractors will do the work
  • I have a way to reach the company that I verified independently

Evidence and scope

  • The line was camera-inspected before any replacement was recommended
  • I have my own copy of the inspection video
  • The estimate names the method: bursting, lining, excavation or combined
  • The estimate states how many feet of pipe are covered
  • The new pipe or liner material and size are written down
  • Pit locations, if any, are marked and described
  • Cleaning, descaling, cleanouts and branch connections are addressed

Permits, restoration and money

  • The estimate says who pulls any permit the city requires
  • Restoration of lawn, concrete and sprinklers is described
  • The payment schedule is in writing
  • Warranty terms are written, including what they cover and exclude
  • I know how changes are handled if the crew finds something unexpected
  • A final camera video is promised before the last payment

Using the checklist

  1. Print one copy per contractor.Fill it in during or after each visit so nothing is mixed up.
  2. Ask for missing items in writing.A blank box is not a failure; it is a question to send.
  3. Compare only complete checklists.Weigh totals once each estimate covers the same scope.
  4. Keep it with the paperwork.File the completed checklist with the estimate and videos.

Common questions

What CSLB classification should a sewer contractor have?

Plumbing work is commonly done under a plumbing license, and some sewer work falls under other classifications. Ask what classification applies and check it at cslb.ca.gov.

Is a verbal estimate enough?

For sewer replacement, get it in writing. Written scope protects you if questions come up later.

What if a contractor will not share the camera video?

That makes it hard to verify the recommendation. It is reasonable to ask why, or to have another licensed plumber inspect the line.
