Washington State Department of Labor & Industries

Consumers and businesses need to learn about prospective contractors before contracts are signed and money is paid. If you have questions about a contractor or need more information about the contractor registration law, call the Department of Labor and Industries on their state-wide toll-free contractor registration information line: 1 (800) 647-0982. Internet users may access the same information and check to make sure a contractor is licensed with a bond and insurance at the Washington State Department of Labor & Industries website.
