How to Choose the Best Plumbing Company in California
Why Hiring a Licensed Plumber Matters
California requires all plumbers to hold a valid C-36 Plumbing Contractor license issued by the CSLB (Contractors State License Board). Unlicensed plumbing work can void your home insurance and result in substandard repairs that cost more in the long run.
Pro Tip: Always verify licenses at cslb.ca.gov before hiring.
