Do you have a list/description for Minnesota? We are Remodeling a home and need to put in a bathroom for the homeowner so he can live there. I heard HVAC, Plumbing and Electrical are all essential but what about the general contractor who schedules them. What about window and door installation? Also, tiling floors and showers to make the plumbing install final? then sheetrock and mudding to finish the room? Lastly, to finish a project with trim and paint; is that essential as well? -Pete St. Paul, Minnesota
