Deck costs in Ocean County, NJ (2026)
Installed pricing in our area generally runs: pressure-treated wood $35–$50/sq.ft., composite (Trex, TimberTech) $50–$75/sq.ft., and full PVC (Azek) $65–$90/sq.ft. A common 16'×20' (320 sq. ft.) composite deck with railings, lighting, and stairs typically lands $16,000–$24,000 fully installed.
Cost drivers: height off the ground (raised decks need more substructure), railing material (cable and aluminum cost more than composite), and any add-ons like pergolas, built-in benches, or under-deck drainage systems.
