Decks & Northwest Indiana Outdoor Living

Expand Your Outdoor Living with a New Deck

Consider how a new deck design or three-season room could improve your home’s livability. Bring us your rough sketch and we’ll bring it to life! Using CAD, we can show you in 3D what your deck plans could look like. We’ll even print out a materials list on the spot.

We carry a large selection of AZEK PVC decking materials including deck railings, deck balusters, hidden fasteners and screws, and AZEK column wraps and trim boards. We also carry TimberTech ReliaBoard,and Fiberon composite decking and railings. Traditional cedar and treated deck components are available as well.

We stock AZEK Pavers®

Environmentally conscious homeowners and contractors are excited about AZEK Pavers®. Made from up to 95 percent recycled materials they retain the strength, durability and appearance of concrete; using them can help a project earn LEED certification.

Weighing in at just nine pounds per square foot, they may be used on flat roofs, walkways, driveways, patios, and other locations. Choose from several colors, each formulated to resist fading. Note that the color and finish will weather over time. Weathering is completely harmless and does not affect durability.

Visit our landscape department for information and inspiration. We’ll show you pavers and underlayment as well as share installation tips.

AZEK Pavers® colors include, from left, Redwood, Boardwalk, Olive, Waterwheel, and Village.
