A: Most composite decks in Pennsylvania and New Jersey range between $80 and $150 per square foot installed. Smaller composite deck projects may start around $15,000, while larger custom outdoor living spaces can exceed $200,000. Final pricing depends on deck size, material selection, railings, stairs, lighting, site conditions, permits, engineering requirements, and custom features such as pergolas, privacy walls, or covered structures.
A: Most premium composite decking products are designed to last 25 to 50 years with proper care. Many manufacturers back their products with long-term warranties.
