Decks, screened porches, and outdoor kitchens, from Bethesda to Silver Spring to Bowie

Long lasting and low maintenance

Living in Northern Virginia and Maryland, we spend a lot of time outside.  That means having an exterior living space that’s durable, low maintenance, yet unique to your home and style.  Consider TimberTech for your composite decking. With some of the most realistic wood looks on the market,TimberTech endures without fading, staining, splintering, peeling, or cracking. And with over 20 finish options and multiple collections, there are plenty of options in which to choose from.
