As with many things in life, you get what you pay for. Initially, Trex decking and railing does cost more, board for board, than timber decking and railing; however, the payoff you get over time in decreased maintenance costs and increased leisure time provides compelling value — so much so, that you’ll often see Trex decks referenced in the listings of homes for sale as an indicator of quality and value that homeowners and estate agents use when selling a home. Of course, the real value is in the time that you enjoy spending outdoors on your Trex deck.
