Before you hire in Alameda County

Match the license number on this page to the name on the contract. Licenses belong to a person or a company, not to a crew.
Confirm the record at CSLB directly. This page mirrors their daily file, but they are the authority.
Ask for a certificate of insurance separately. CSLB licensing does not verify that a contractor carries liability coverage.
Get the license number written into the written estimate.
