Two classifications you will not find here

There are no plumbing or electrical classifications in this data, and that is not an omission on our part. Washington licenses electricians and plumbers through separate L&I programmes that publish separately from the contractor registration file this directory is built on. A plumber or electrician may still appear here if they also hold a contractor registration, but the trade field will not say so. To check a plumbing or electrical credential, go directly to L&I.
