Finding the Best Contractors in Orange

When hiring a contractor in Orange, California, due diligence matters. The contractors listed above have been verified against multiple government databases and achieved Safety Scores of 85 or higher—placing them among the most compliant contractors in the area.

Our Safety Score considers:

  • License Status — Active CSLB license with proper classifications
  • Workers' Compensation — Current coverage to protect you from liability
  • Contractor Bond — Financial protection if work isn't completed
  • Federal Compliance — No debarments, wage violations, or safety citations

While a high Safety Score is a strong indicator of a reputable contractor, we always recommend getting multiple quotes, checking references, and verifying the contractor is licensed for your specific type of project.

Safety Scores are calculated based on publicly available government records and are updated weekly. For official verification, check directly with CSLB at cslb.ca.gov.
