There are variety of decking materials on the market. Cedar, Pressure treated, composite, or vinyl. We cover the first three. We can also help you out on your railing choices. 5/4 cedar decking comes in 1 x 4 or 1 x 6 and they look great. Stain them up once every five years and you are good to. Pressure treated has no need for stain, but can be after a year or so, until they are dried out. Pressure treated is the least expensive. Trex decking is the lowest maintenance. Just needs to be washed a couple of times a year and its fine.
