Why verify a California plumber?

Hiring an unlicensed plumber risks code violations, voided home insurance claims, and water damage that can cost tens of thousands to repair. Always confirm a plumber's license before signing any contract.

How to hire a California plumber safely

  1. Verify the plumber's license is active and not expired or suspended.
  2. Confirm they carry general liability insurance and worker's compensation.
  3. Ask for a written estimate that breaks out parts, labor, and permit fees.
  4. Check that the license type covers the specific work (e.g., gas line vs. water heater).
  5. Get at least 3 references from jobs completed in the last 12 months.
