Composite decking has its pitfalls. It isn't as durable as other materials, and it is more expensive than some. It also doesn't look completely natural. Compared to pressure treated wood, a composite deck can cost 15 to 20% more. However, it requires less maintenance. With a composite deck you will need to sweep leaves and dirt off regularly, as you do with most outdoor surfaces. You will also have to wash them down every once in a while. Using a hose is a good option for both of these problems. Lastly, you'll have to "comparison shop." This means looking at all your options. There are so many different composite manufacturers and types of composite decking. You'll have to compare prices, appearances, and durability, as well as look for warranties.
