Deck & Patio Building in Great Falls, MT
Great Falls deck and patio builders in this directory cover central Great Falls, Black Eagle, Sun Prairie, and surrounding Cascade County. A typical 12x16 pressure-treated deck runs $6,500-$11,500 installed. Composite (Trex, TimberTech) decks of similar size run $11,500-$22,000.
Great Falls Building Department permits all decks. Montana's deep frost (48+ inches) demands frost-protected footings. Most reputable builders use helical piles or sonotube concrete with rebar.
