Building with TimberTech means the most technologically-advanced materials and the most design options for a more enjoyable, longer-lasting outdoor space. TimberTech’s superior 4-sided capped composite decking offers complete surface protection and elegant design- all backed by a 30-year limited product warranty and a 30-year limited fade and stain warranty.

Get the Deck That Suits Your Style with Genovations® PVC Decking. Genovations® installs faster with its tongue and groove design and stays cooler due to his hollow design that most other composite alternatives. Genovations® is incredibly strong and lightweight as well. It is the only composite deck board on the market that can be installed directly onto concrete. Avoid the hassle of having to build a frame! And don’t forget Genovations® has no organic fillers which means a moldy surface will never compromise the integrity of your dock or deck.

Westbury Railing

Beauty meets strength. Simple meets innovative engineering. Westbury® Aluminum Railing was designed with these essential elements in mind. With a variety of designs, colors, and textures, you decide what fits you. Whether you add railing to the front of your home or to the deck in the back, you will have turned your home into a very welcoming retreat. We have several sections of Westbury® railing inside our showroom, including the Westbury® Verticable railing. This popular, attractive railing option doesn’t block the view and gives you an attractive rail unlike any other.
