Deck Surfaces

  • Pvc Decking

    PVC is a wood-alternative decking surface that’s easy to install thanks to its light weight and compatibility with a broad variety of fastening options. It’s durable, scratch- and fade-resistant, and is recyclable at the end of its life. Its greatest advantage is its low-maintenance nature—all it requires is a twice-yearly cleaning. We’re proud to carry the highest quality PVC decking surfaces from AZEK and WOLF.


    Made from up to 97 percent recycled content and industrial material waste, capped composite decking surface is a great green alternative to wood decking. Capped composite decking is heavy and durable and resists scratches, fading, and staining. It’s also easy to care for: a twice-yearly cleaning is all the maintenance it requires, saving you time—and money—down the road.


    Wood decking is a classic green option with choices that include tight-knot and clear grades of cedar, heat-treated softwoods, sustainably harvested hardwoods, and more. From both low and high maintenance options that will either blend in or stand out, we have a wide variety of wood decking surfaces to meet your needs.

  • Fasteners

    Secure your decking with a fastening system that suits your surface, from stainless steel and ceramic-coated screws to plug systems or hidden fastening systems. Visit a Dunn Lumber decking showroom to speak with a specialist—whether you’re working with a PVC, composite, or wood decking surface, we’ll help you make the best fastener choice.


    Waterproof your plywood decking surface with an elastomeric coating such as GacoDeck. When applied over plywood, it creates a fully adhered, durable, weathertight deck surface that can act as a roof over living spaces below.
