How to Verify a Contractor in Windsor

Manual contractor vetting takes 45+ minutes per sub and still misses violations in databases you don't know exist. SiteVetter runs 6 data source checks in seconds: CSLB license status, SAM.gov federal debarment, DOL wage violations, OSHA safety citations, EPA environmental records, and building permits.

Contractors in Windsor serve local residential and commercial construction needs.

Of the 322 CSLB-registered contractors in Windsor, 97% hold active licenses and 15 have at least one record in federal databases. Under California's "Controlling Employer" doctrine, general contractors can be held liable for subcontractor safety violations—making verification a legal necessity, not optional due diligence.

5-Point Verification Checklist for Windsor Contractors

  • CSLB License: Confirm Active status (not Suspended, Revoked, or Expired)
  • Workers' Comp: Verify current coverage—exempt status means no employees
  • Contractor Bond: California requires $25,000 minimum (SB 607, Jan 2023)
  • Federal Debarment: Search SAM.gov for exclusion records
  • Safety & Wage History: Check OSHA citations and DOL wage violations

Data sourced from California Contractors State License Board and federal databases. Updated weekly. For official verification, check directly with CSLB.
