The cost of a 20x20 composite deck can vary based on several factors, including the type of composite material used, local labor rates, and any additional features or customizations. On average, composite decking materials can range from $30 to $60 per square foot, including installation. Therefore, for a 400-square-foot deck, you might expect to pay between $12,000 and $24,000, though prices can vary based on specific circumstances.
