What this means

This licence is no longer in CSLB's active licence file (we last saw it there on Oct 29, 2026). That usually means it expired, was inactivated or was revoked. Check the free CSLB lookup before relying on it.
Contractor's bond: $25,000 with Western Surety Company. The bond is there to pay consumers and workers harmed by licence-law violations; it is not liability insurance and it does not guarantee the work.
Workers' comp: exempt. The contractor has told CSLB it has no employees. If a crew shows up on your job, ask for a current workers' comp certificate; a contractor with employees must carry workers' comp.
