This is a western red cedar deck with a light brown oil applied to it. I have been maintaining this deck from 2004. This deck was a major restoration being that it was around 20 years old back in 2004. There is also a tree overhanging it which causes moisture problems, plus the tree debris clogs up the spacing in between the boards restricting drainage and airflow. Through my restoration and yearly maintenance program this deck has reached over 30+ years of age.
