Boiler, Hot Water & Steam Contractor Verification - Page 14

California requires all contractors performing boiler, hot water & steam work valued at $500+ to hold a valid CSLB C-4 license. Of the 710 licensed boiler, hot water & steam contractors in the state, 98% currently hold active licenses and 13.7% have at least one federal compliance record.

Manual vetting takes 45+ minutes per contractor and routinely misses violations in databases most people don't know to check. SiteVetter runs CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, and EPA environmental records in seconds—creating a timestamped compliance artifact.

Verification Checklist for Boiler, Hot Water & Steam Contractors

• Get at least 3 written quotes before selecting a contractor

Why Verification Matters for Boiler, Hot Water & Steam Work

Under California's "Controlling Employer" doctrine, general contractors face liability for subcontractor safety violations. For boiler, hot water & steam work specifically, 13.7% of licensed contractors have federal records that a standard CSLB license check wouldn't reveal. SiteVetter's 5-database check catches what a single-source verification misses.
