The licence check in Washington
Washington publishes a roster we can check a company against: Washington L&I Contractor License Data (Washington State Department of Labor and Industries).
We hold the roster and have not run it against these 472 companies yet, so every licence on this page currently reads as unverified. That is our backlog and not their standing.

How these are ranked
By verification score, out of 100, across six checks published in full on how we rank. No company paid to appear and none can pay to rank higher. The score counts records and is not a judgment about workmanship.
