This will be a short description as composite decking is a overpriced and failed product. Composite decking severely fades in its first year; many of the fastening systems for composite decking are top screws which degrade the beauty and longevity of the product from the first day. As a deck contractor for many years we have found cases of Composite decks in the Kansas City area to deteriorate from the inside out. Wood and glue is the common components of composite and in our climate that spells trouble. Although if directed, we will install composite, we will not warranty any aspect of the product. Ask to watch our 3 year case study video during your in home consultation. This test was performed on pressure treated, composite, and PVC decking products.
