For the longest time, wood fences have been built using wood posts. - Redwood Posts - Pressure Treated Posts - Cedar Posts But they all have one MAJOR flaw: they will rot and will break or fall down over time! No matter what you coat the wood post with to try and prevent it from rotting, it will always rot because it's a natural product. Check out a really cool alternative if you still want the look of wood but want more durability: The Metal T-Post. (There is also a brand called Postmaster+). We'll have a video coming out in the future showing exactly how we replaced a rotted wood post with one of these Metal T-Posts on a cedar fence and how it turned out. (The original cedar post we removed was only 3-5 years old!) See for yourself in the video below how an untreated post rotted in our backyard after only 3 years!
