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.
