Composite decking is an alternative option to wood or plastic decking materials. Composite decking is an engineered product that is a mix of wood fibers and plastic material. Often the plastic comes from recycled or reclaimed sources. NW Surface Cleaner offers deck installation with composite products from either Trex or TimberTech. A composite deck generally lasts for at least 25 – 30 years, with some estimates up to 50 years.
