Source: California Contractors State License Board's License Master file. CSLB's file covers licenses that are current, or expired but still renewable. Cancelled and revoked licenses aren't in it, so if you can't find someone, check the official search. Only licenses that are active in the file and list an address in
Saint Louis are shown; a contractor based elsewhere can still work here. LicenseLookup is an independent guide, not a
government agency, and this is not an endorsement of anyone listed. See our terms .
