Checks for Plumbers

  • Plumbing has two layers: the business registers as a contractor, and individual plumbers hold certificates of competency. Ask who will do the work and check their certificate on L&I Verify.
  • Trainees may work only under appropriate supervision; ask who is supervising.
  • Most plumbing beyond simple repairs needs a permit from your local building department.

How to Verify This Contractor

  1. Use the Confirm on L&I Verify button and search registration DMPLUPT793O3 or UBI 602785787. The status there is the official one.
  2. Check that the name on your bid or contract matches Dm Plumbing/Backflw Tstng LLC exactly (a limited liability company).
  3. On L&I Verify, look for bond claims, lawsuits and any newer registration.
  4. Ask for a certificate of insurance sent directly by the insurer, and compare it with the Western National Assur Co policy on file.
  5. Check the individual certificate of the person doing the work, not only the business.
