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.
It expires in 85 days (Jan 31, 2027). California licences renew every two years; work done after expiry without renewal is unlicensed.
Contractor's bond: $25,000 with Philadelphia Indemnity 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 State Compensation Insurance Fund, policy through Sep 20, 2027.

Watch this licence: $9/month. We email you when CSLB's file shows a change to this licence's status, bond, workers' comp or expiry. Checked every Monday and Thursday. Cancel any time.
