Licensed master plumbers in Howard Lake, MN

7 individuals with a Minnesota DLI master or restricted master plumber license list Howard Lake as their city (DLI file downloaded November 4, 2026).

Read this before you call. These are individuals, not businesses. Minnesota law says no one may perform or offer to perform plumbing work, with or without pay, without a plumbing contractor license (Minn. Stat. 326B.46), and a contractor license is a separate license from a master plumber license. Many master plumbers work for the contractors listed in this directory. Ask whether the person holds a plumbing contractor license or which licensed contractor they work for, then check it with DLI. See who may do plumbing work.
