Check the license first
- Ask for the number.Every contractor doing this work in California should be able to give you a CSLB license number.
- Look it up.Search the number at cslb.ca.gov and confirm it is active.
- Match the name.Make sure the business name on the license matches the company you are dealing with.
- Note the classification.Check that the license classification fits plumbing work, and ask if you are unsure what it covers.

Common questions
Is a business license the same as a CSLB license?
No. A city business license is different from a contractor's license from the Contractors State License Board. Check the CSLB license at cslb.ca.gov.
Should I get more than one quote?
For a simple clearing, it may not be practical. For major sewer repair, a second written opinion is reasonable.
What if I already hired someone without checking?
You can still look up their license at cslb.ca.gov and ask for written terms before any further work.
