Plumber directory, checked against state license records.

Search plumbers in California by business name or city. Every listing came from a state’s own public records, not a paid directory or a scrape, and is listed A to Z by name. We badge the ones matched to an active credential, say plainly when we have not, and never publish a review we did not collect from a confirmed customer.
