I would NOT use Timbertech. Have the floorizon from them. Less than a year old and it is already warping. It covers with mold every time it rains. I'm in the northwest and had alot of trees close to the house.

My Mom & Brother have Trex and less trouble. It cleans easier and doesn't mold after every rain. Even when it hasn't been cleaned for a couple years, it doesn't have the mold the Timbertech does.
