Sean Krubinski
Sean Krubinski holds California contractor licence 992919 (General Building, Painting and Decorating) in Diamond Bar, Los Angeles County. Status: Active · expires May 31, 2028.
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 American Contractors Indemnity 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.
- Our records show 1 change to this licence since we started tracking the CSLB file; see the change history below.
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.
