Composite decks built from scratch can cost about $50-$60 per square foot when built by a licensed deck builder in Hunterdon County, NJ.
Composite decks are becoming a popular option for homeowners for a number of reasons. They’re durable, easy to maintain and can add huge aesthetic appeal to your outdoor space. That being said, what does it cost a New Jersey homeowner to have a composite deck built by a licensed deck building contractor in 2025?
For about $50-$60 per square foot, most homeowners in New Jersey can expect a fairly involved scope of work for a brand-new composite deck build. These scopes include planning and construction components. Planning consists of all back end, pre-construction tasks such as drawings of specific deck dimensions, municipal permitting, scheduling inspections and surveying deck location on site.
Construction begins with footings and substructure framing. Subsequent steps include installing composite decking and railings and a staircase. Factors to consider like deck height from ground level and planning for more than one staircase will likely increase project costs. Additional features like composite fascia, skirtboards and lattice work will also likely reflect a higher final price tag.
If you also have an existing deck that needs to be demoed and disposed of, it’s fair to expect additional project cost on top of new deck construction to cover demo labor and disposal fees.
Although the up-front investment is slightly more than a traditional pressure treated wood deck build, having a new composite deck built as an extension of your current living space is a fantastic way to reduce annual deck maintenance and boost your outdoor aesthetic appeal!
