Pictured above is a beautiful and sturdy cedar post and rail fence. This 100% northern white cedar round post and with dowelled rail fence was installed recently in Fair Haven, NJ at Knollwood School. This fence was designed to replace an old fence of the same kid that had seen better days. Cedar is a low maintenance option for fencing and can be left in its natural state without staining. However, cedar can be stained, painted or sealed with a clear sealant to extend its life and protect it against the elements. The lifespan of a cedar fence can range from 15 to 20 years and up.
