How this ranking works
Organic results require an active L&I license, the correct class for the trade as the firm's primary or tied fit (a mechanical company that also holds an electrical license does not lead the electrician list), and at least one job-relevant city building record in this city. They are ranked by the number of relevant jobs, then by how recently the firm worked, then by how long the firm has been licensed. This reflects license standing and real city building records - it is not a workmanship guarantee. L&I does not publish a disciplinary file, so a clean record is not part of this ranking. Promoted entries, when present, are paid placements and are not scored by these rules.
Confidence: high. The job type and the license class both match this trade.
