I built my fence with Yella Wood brand lumber 13 years ago and already it had rotted through and fallen over. I used 4×6 posts for strength and longevity but bought a headache and sorrow instead. I am currently replacing/ rebuilding the fence at a great cost of labor and money. At that time I paid about 1200 dollars for materials and 1200 for labor. My total cast was approximately 2, 400 dollars. I'm saving the rotted timbers for chemical analysis and the YELLAWOOD tags I find hidden within the cement at the bottom of the posts.
