How to check a limited specialty contractor's license in Winchester

  1. Find the business in the list below, or search all 29 Winchester listings, and open its profile. You want a Clear status and the C-61 classification (a B license can also cover it as part of a multi-trade job).
  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 79.3% of Winchester limited specialty contractors claim a workers' comp exemption, ask who will actually do the work. Hiring checklist.
