Sheng-Tien Tsai
Sheng-Tien Tsai holds California contractor licence 980128 (General Building, HVAC (Heating, Ventilating and Air-Conditioning)) in Montclair, San Bernardino County. Status: Active · expires Jan 31, 2027.
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 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: Workers' Compensation Insurance with Transportation Insurance Company, policy through Jan 14, 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.
