How to vet a plumber in three steps

Plumbsie doesn't send plumbers or refer jobs. Here's what to check before you hire anyone.

Check the license

Look up the plumber's license number at cslb.ca.gov. Make sure it's active and covers plumbing work.

Know typical costs

Read our cost guides so you know a fair range before you call.
