Common questions

What classification should a plumber have?

The CSLB lookup shows each license's classification. Ask the contractor to explain how their license covers the work you need.

Is a business license the same as a CSLB license?

No. A city business license is different from a state contractor license. Check the CSLB license specifically.

How many contractors should I talk to?

For larger jobs like reroutes or repipes, many homeowners compare at least two written proposals.
