Deck building costs near Rosemount, MN vary significantly based on size, materials, design complexity, and the contractor you choose. As a general benchmark, a professionally built composite deck in the Twin Cities metro typically runs between $15,000 and $45,000 or more for larger or more complex builds — but the number that matters most is what you are getting for it. At Destination Decks, our pricing reflects premium materials from manufacturers like Trex and TimberTech, structural framing that exceeds Minnesota code requirements, proper permitting, clean jobsite standards, and warranty coverage that goes well beyond the industry norm — 10 years structural, 5 to 7 years labor.
