How to Verify a Sheet Metal Contractor (C43) in California

California requires all contractors performing sheet metal work valued at $500+ to hold a valid CSLB C43 license. Of the 1,346 licensed sheet metal contractors in the state, 96% currently hold active licenses and 13.1% 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 Sheet Metal Contractors

  • Verify the contractor license is active and in good standing
  • Request proof of insurance and bonding
  • Get at least 3 written quotes before selecting a contractor
  • Check federal databases: SAM.gov, OSHA, DOL, and EPA records
  • Confirm bond: California requires $25,000+ contractor bond (SB 607)

Why Verification Matters for Sheet Metal Work

Under California's "Controlling Employer" doctrine, general contractors face liability for subcontractor safety violations. For sheet metal work specifically, 13.1% 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.
