How to check a plumber's license in Modesto

  1. Look the company up by name or license number (search Modesto). On the profile, confirm three things: Clear status, the C-36 license for this kind of work, and a contractor's bond on file.
  2. Re-check the same number on CSLB's Instant License Check the day you sign; our copy is refreshed weekly and 6.7% of Modesto listings here already show a suspension.
  3. Match the license holder's name to the name on the written contract and the person you meet. Since 53.3% of Modesto plumbers claim a workers' comp exemption, ask who will actually do the work. Hiring checklist.
