What this means

The licence is active: CSLB lists its status as clear. That means no suspension is on file; it does not rate the quality of the work.
Contractor's bond: $25,000 with Business Alliance Insurance 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: Workers' Compensation Insurance with Amtrust Insurance Company, policy through Nov 16, 2026.
