Orange County insulation licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 90 active C-2 insulation and acoustical licenses in Orange County, 11 of them registered in Orange. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Orange license has been held 22 years, and the longest-standing one dates to 1948. 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: 11 of Orange's 11 licenses (100.0%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 90 of the county's 90 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.
