About Us

We are a small, family owned building supply store in beautiful downtown Castle Rock, Washington. Castle Rock Building Supply has been serving Cowlitz and southern Lewis counties since the 1930s. Owner Ken Campbell has been serving the area since the 1960s and has been providing the building material you need since 2005. Customer service is our business, and we are able to provide it on a personal level that you can't get at larger stores.
