timbertech_logoTimberTech composite decking and railing products add beauty to homes, businesses and resorts. What’s more, TimberTech is low maintenance, safe, durable, and can even help to increase the value of your home.

TimberTech maintains its color and beauty for years without the work of annual painting or staining. And, because it resists mildew, warping and insects, there’s no need to replace rotting, uneven or termite-damaged boards. This saves time and money over the life of your deck. Caring for TimberTech is easier than wood and will allow you to focus on maximum enjoyment instead of maximum maintenance.

TimberTech’s warranty offers 25-years of coverage. And our warranty can be transferred to a second homeowner – a great selling feature when you’re ready to relocate. So the first, and second, TimberTech product owners can have peace of mind that their outdoor oasis will look beautiful year after year. In addition to the already great warranty coverage, the Earthwood Evolutions product line is covered by a 25-year fade and stain warranty. For commercial applications, TimberTech also offers a 10-year limited warranty. And in the unlikely event that you’ll have to contact us for warranty assistance, we separate ourselves from the competition by placing high priority on top-notch customer care after the sale.

What goes better with your new deck from Interstate than the perfect railing? Our railings will complement any decking you put down. From composite to aluminum, your guests will wow at the beauty and elegance of your back yard. See what we have to offer.
