Heller Lumber Co. offers full lines in decking and railing  from traditional treated and cedar decking and posts to today’s top-of-the-line composite decking and railing products. Whether you choose traditional decking from sustainable forests or composite decking that is almost maintenance-free, we have the best of both options.

At Heller Lumber Co. you’ll find decking products from composite industry leaders along with the railing components that add safety and style to compliment your new deck.

Whether it’s composite decking, pressure treated, or cedar decking material at Heller Lumber Co., we have the material you need.  We are here to help you with our deck design services or you can contact us for a estimate today!


TimberTech composite decking and railing is a revolutionary alternative to traditional wood that doesn’t rot, warp or splinter — and never needs staining or sealing.

Imagine a beautiful backyard oasis that looks like new year after year. A stunning pool deck that makes entertaining a joy. Or a carefree boat dock that defies the elements, day in and day out.

Easy to install and easier to maintain, TimberTech offers you more colors, more options, more possibilities — and promises you less worry than wood or other composites. Because, finally, your ultimate outdoor living space is for living, not working.
