Composite decking is an alternative option to wood. Composite decking is an engineered product that is a mix of wood fibers and recycled plastic material. These products are a low maintenance option for those who don’t want the hassle of having to stain their wood deck every few years. NW Surface Cleaner offers deck installation with composite products from either Trex or TimberTech. A composite deck generally lasts for 20-30 years and comes with a fade, stain and physical integrity warranty.
