What you are protecting against
Most plumbing problems end well. The ones that do not usually share a pattern: no written scope, a price that grew without explanation, work done without a needed permit, or a contractor whose license did not cover the job. Each of those is easy to check up front.
In California, contractors are licensed by the Contractors State License Board. The board's website, cslb.ca.gov, lets anyone look up a license by number or name and see its status, classification and bond and workers' compensation information.
Checking a license
- Ask for the license number.A licensed contractor should give it readily, and it often appears on estimates, invoices and vehicles.
- Look it up at cslb.ca.gov.Confirm the license is active and the business name matches the company you are dealing with.
- Check the classification.Make sure it covers plumbing work, or the specialty involved.
- Review bond and workers' compensation.The record shows whether these are on file. Ask about general liability insurance separately.
Before work starts
- License number verified at cslb.ca.gov.
- Written scope listing the work, materials and what is excluded.
- Written price, and how changes will be handled if more work is found.
- Who will do the work: employees or subcontractors.

Common questions
What if the license is in a different business name?
Ask why. The license should belong to the company you are contracting with.
Do small repairs need a licensed contractor?
California has rules about when a license is required based on the job. Hiring a licensed contractor avoids the question; you can read more at cslb.ca.gov.
Is a verbal quote enough?
For anything beyond a simple repair, get it in writing so both sides agree on what is included.
