How long does composite wood decking last?
You can expect composite wood decking to last 20 to 30 years, with an average of 25 years. Here’s a graph that compares composite decking life expectancy to other deck/patio materials.
Composite deck boards need minimal maintenance and does not splinter like wood, but the surface gets much hotter than wood on a sunny day. They are composed of equal parts of recycled polyethylene plastic and wood fibers, such as sawdust, and come in multiple wood-like colors embossed with a wood grain pattern.
