What is certain is that rot is a big threat to the posts. We have the experience and the products to offer you the best post protection on the market today.

Let’s take a closer look at how to prevent fence post rot.

How does the rot get into the fence posts?

To know how to prevent fence post rot, you must know how it strikes in the first place. The crucial ground-line level is where all the action happens. This is the area about eight inches into the dirt, where rot likes to work.

The ground-line level is where your fence posts are most vulnerable to attack.

Moisture seeps into the post below ground from the dirt. The wood expands and contracts. Oxygen in the soil combines with other elements, making it perfect for rot to take an interest. The soft wood attracts all the bad guys, and soon the rot is eating away at your post. All the action happens where you can’t see it…until it is too late.

You need post protection, and the ground-line level is where it goes.

Applying the rot barrier

Knowing how to prevent fence post rot is half the battle. Doing the work wins the war.

The rot barrier Postsaver® Sleeves come in several sizes to fit all posts. You can buy them in single units, packs of ten, or in rolls for larger jobs. They work on fence posts, mail posts, deck posts, and any other ones you may use around the yard.

They are easy to apply.

You measure and mark where the rot barrier goes on the posts. When ready, slide the sleeve into place and angle the fence post to keep it steady. Run a heat gun gently over the rot barrier sleeves until the bitumen melts and seals to the wood. Use a roller to get out any wrinkles or air bubbles on square posts.

When it dries, you can get to work burying the fence posts in the dirt.
