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 Jet 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. The surety has filed notice to cancel this bond effective Nov 12, 2026; unless a replacement bond is filed, the licence will be suspended on that date.
Workers' comp: Workers' Compensation Insurance with Technology Insurance Company Inc, policy through Jul 1, 2027.
