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.
