Products

Big Sky Doors’ warehouse in Billings, MT, maintains an inventory of approximately 350 doors along with thousands of linear feet of millwork, including jambs, casings, and baseboards.
While we offer a wide variety of designs and wood species, and can customize doors to any size, it's impossible to stock everything. Custom and special orders typically take four to six weeks to produce, depending on the complexity and design.
