I built a large deck using Timbertech (
www.timbertech.com), and while expensive initially I couldn't recommend it more.After a hard winter, with a dog running all over it with muddy paws, a quick hose down and it looks like new. It will never need paint or stain. If the right hardware and materials are used it will last a lifetime.The key question would be, what is your time worth? The cost is quickly justified when you factor in the low maintenance of the product.Good composite looks better than natural wood.
