The web site has a license number. First sentence on this page:

In my State, license-board enforcement is limited to job-site stings, AHJ or customer complaints, and unauthorized lien actions, which invite the lawless to demonstrate their incompetence to a law enforcement official.
In my State, the general public are invited to send copies of advertising violations to an automated FAX or email address, but the license board employee (under hiring freeze) must invite such violators to sting projects, where they can be served a notice to appear at
misdemeanor civil hearings.
Except for sting projects in declared disaster areas in CA, the CSLB has no arrest or incarceration authority. While recent "stop order" authority may halt work, CSLB won't follow the violator around to prevent other buildings from burning down, nor force anyone to appear in court.
Labor law, advertising law, insurance law, downpayment limits, and project abandonment that results in supplier liens on customer property are caused by both un/licensed contractors. Further, a lack of enforcement resources, State budget crisis, and due-process requirements can lead violators to believe they may never get caught.
Because of exemptions to workers comp. for the first 52 hours, for clients that have property insurance with "Personal comprehensive liability" the best consumer protection for small service calls may be hiring a qualified Journeyman lacking contract, permit, or lien authority.
It may be preferred, not just legal in my State, to hire unlicensed journeymen without employment proof, to perform service work under the "unlicensed" minor work exemption set by the Contractors State License Board (CSLB).
