The Hazardous Substance Removal Certification program prepares licensed contractors to obtain this specialized CSLB certification.
Unlike an additional classification, the state does not require four years of experience for this certification. However, applicants must already hold a general contractor license. CLRG assists with preparation and application to ensure compliance with CSLB requirements.
