Composite Deck Board Prices

Composite decking prices range from $4 to $13 per square foot. The product usually comes in boards, though some manufacturers sell square tiles. The boards measure by the linear foot, but most pros quote prices per square foot. The most common size is about 1.25 inches thick, 5.25 inches wide and varying lengths.

Maintenance-Free Composite Wood Pricing

Composite Decking Calculator

Pros usually estimate prices per square foot. You can determine the total square footage by multiplying the length by the width. Add an extra 10% to accommodate variable board length. Keep in mind that certain costs, like railings, are set by the linear foot.

PVC Decking Prices or Vinyl Decking

Polyvinyl chloride (PVC) decking costs $5 to $13 per square foot for the boards. While composite contains plastic mixed with wood or bamboo, PVC is entirely made of plastic.

Cellular PVC

Cellular PVC is built to look and feel much like wood. This means that pros can cut these boards without the risk of splintering or cracking, a common problem with other vinyl materials like siding.

Recycled Plastic Decking

Most PVC and composite decking products use recycled plastic. Some do not use any new materials, making them highly sustainable. If you’re looking for a green alternative that still looks like wood, this is a great choice.

Other Synthetic Decking Costs

When you think about the cost of a PVC deck, remember that you’ll need to pay for:

• railing
• substructure
• posts
• hardware

Composite Decking vs. Wood Cost

Cost of PVC Decking vs. Wood

PVC decking costs $5 to $13 per square foot, compared to $10 to $22 per square foot for wood. PVC prices run lower largely because it is easy to recycle into new material. Since the installation process can be fairly similar, labor tends to be about the same.

PVC vs. Composite Decking Costs

Composite decking costs $4 to $12 per square foot, closely overlapping PVC at $5 to $13 per square foot. Composite tends to last longer. Materials made entirely of plastic can stretch and bend over time, shortening their lifespan.

Fiberglass Decking

Fiberglass decking is less common than PVC or composite. You'll need to ask a pro for pricing and availability. It is best known for its ability to repel water in areas with heavy rains. Homeowners prefer it for coastal regions and roof decks.

DIY vs. Hiring a Composite Deck Contractor

Since materials cost the most, most homeowners conclude that it’s easier to go with a professional installer. Deciding whether to build a deck or hire a pro depends on your skills. Many composite and PVC manufacturers sell only to authorized dealers, so DIY may limit your choices. If you make a mistake, repairing a deck averages about $1,700.

When you plan to hire a composite deck builder near you, be sure to get quotes from at least three. Interview your deck builder before making a decision.
