According to Love To Know, a home improvement site, plastic-wood composite deck materials and supplies can cost between $10 and $20 per square foot.
Love To Know also claims that professional installation on a composite deck construction project can cost an extra $5 to $20 per square foot on top of material costs.
Composite deck materials are more expensive than traditional wood materials, but the extra cost is offset by the benefits offered. Composite decks are very durable, and will not splinter or crack, according to Service Magic, a home improvement site.
Composite decks will require very little maintenance throughout the years. The consumer should expect little in the way of additional regular maintenance costs. No sealant or staining will ever be needed to keep the deck from warping or rotting.
If the consumer chooses to include such features as benches, rails and steps, the overall price tag of the project will increase.
