Before you hire in Bellingham County

  1. 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.
  2. Confirm the record at L&I directly. This page mirrors their daily file, but they are the authority.
  3. Ask for a certificate of insurance separately. L&I licensing does not verify that a contractor carries liability coverage.
  4. Get the license number written into the written estimate.
