  2. Before any money changes hands, verify the license on CSLB's own lookup. Our data comes from CSLB's weekly file, so a very recent change may not show here yet.
  3. Match the license holder's name to the name on the written contract and the person you meet. Since 52.8% of Lomita plumbers claim a workers' comp exemption, ask who will actually do the work. Hiring checklist.
