In a comfortable home with slight humidity variations through the seasons, plastic wood for decks responds by expanding and contracting. These changes may be noticeable. During warm, humid weather, plastic wood expands. During dry weather, plastic wood contracts. This seasonal movement is a normal characteristic of plastic wood for decks, and it never stops, regardless of the age of the wood. One of the best ways to ensure that plastic wood for decks will give the performance homeowners expect is to install humidity controls and ensure that they are functioning before the flooring is installed.
A homeowner who chooses plastic wood for decks is making an investment in a floor that will last 40 years or more, and he or she should protect that investment by installing humidity controls–a tool that helps the floor maintain a beautiful, trouble-free appearance.

Basic composite decks require periodic cleaning and care should be taken not to scratch or stain them.
