East Islip Lumber specializes in decking! Whether you want the classic beauty and lower initial cost of wood, or the durability and low-maintenance of a man-made materials, East Islip Lumber can help you find the right product to achieve the look you dream of. 



The beauty and natural look of wood is unsurpassed. Among the types of wood decking we stock: Treated Yellow Pine, Common and Clear Cedar, Mahogany, and IPE.  Also readily available are Alaskan Yellow Cedar, Cumaru, Garapa, Massaranduba, and Thermory (Ash).



Composite decking is a modern, low-maintenance solution to decking.  Easier to care for than wood, it resists mildew, warping, and insects, and maintains its beauty and color for years without the need to paint, seal, or stain. While there are many brands of composite decking on the market, East Islip Lumber stocks brands known for quality durability, and customer service.

Trex Decking

The originator of composite decking, Trex offers exceptional style in a broad range of colors and finishes. Trex decking is comprised of 95% recycled materials—namely, recycled wood, sawdust and plastic film. And now that same low-maintenance innovation is available in Trex railing and trim, and outdoor lighting.


Available in a large variety of colors and styles, there is a TimberTech decking option designed to fit your life and design preferences. TimberTech composite decking and railings are capped on all 4 sides, unlike other brands on the market; so mold, insects, rot & water cannot access the inner core, causing damage and the need for replacement. TimberTech’s mission is building America’s most enduring, durable, and enjoyable outdoor living spaces for you and your family to enjoy for many years to come.
