Montana licenses plumbers through the Board of Plumbers. A construction contractor license is not a plumber license. Before you book in Billings, look the plumber up in the Department of Labor & Industry licensee lookup and confirm the license is active. The city still controls the plumbing permit, so ask who will pull it. This page shows which Billings plumbers AI assistants named most often across answers RecommendRadar ran and stored, how often each appeared, and the sources those answers cited. Visibility to AI isn't the same as good work, so ask for the license and confirm it.
