Montana is the land of big skies, so wanting to become a plumber and running your own business in this beautiful state simply makes sense. Here's what you need to do to accomplish that goal:

  • Pay the $100 exam fee and pass the journeyman exam.
  • Pay the yearly $170 licensure fee.
  • Show evidence of a journeyman or master license from Oregon, Idaho, North Dakota, or South Dakota.
