San Bernardino County insulation licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 53 active C-2 insulation and acoustical licenses in San Bernardino County, 7 of them registered in San Bernardino. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median San Bernardino license has been held 25 years, and the longest-standing one dates to 1981. California law requires workers' compensation cover for C-2 licensees, so it is a legal baseline rather than a way to tell two contractors apart: 4 of San Bernardino's 7 licenses (57.1%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 53 of the county's 53 licenses carry the same $25,000 bond California sets by statute. 4 county licenses reach their expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.
