On average, the estimated material cost for a composite deck runs from $15 - $30 per square foot (including substructure, decking, hardware and fasteners). We recommend using our online cost calculator tool and guide to get an estimate for your project's cost. For a true cost estimate, reach out to a Trex retailer or TrexPro deck builder.
*Average price range excludes Trex Signature decking, our luxury decking collection. Trex actual material costs and install costs can and will vary based on geographic area, site location, seasonality, design complexity, whether the product is stocked locally, and additional features such as stairs, angles, curves, lighting, etc. For most professionally installed projects, materials constitute up to one third of the total cost.
