how to prevent wood fence rot


First, the bad news. Since wooden fences are exposed to weather and elements, all of them eventually rot. And rot affects both the beauty and strength of a fence..

Now for the good news!

When you understand what causes wood fence rot, you can use the tips outlined below to install a fence that will remain beautiful and strong for a long, long time.

So, let’s get started!

What Causes Wood Fence Rot:


Dry Rot

When a wooden fence loses the natural oils on its surface, dry rot occurs. This loss of oils is inevitable due to continuous exposure to sun and wind. As the protective oils begin to disappear, wooden fences become brittle and break easily. Dry rot is especially troublesome in harsh, dry climates.

Wet Rot

Wet rot happens when wooden fences are in continual contact with moisture due to rainfall, snow, or lawn sprinklers. As they succumb to wet rot, the wood becomes cracked and soft. This can lead to fungal growth and a damp smell may be present.


How To Prevent Wood Fence Rot:

Use Proper Wood

Choose quality fence materials that are resistant to decay. Hard woods like cedar, cypress, oak, and redwood are all good choices. On the other hand, softer woods like Douglas fir, tamarack or pine won’t provide long-term prevention of decay. Softer woods may cost less, but in the long run they’ll add more expense if rotted posts or even an entire fence needs replacing.


Use Pressure-Treated Materials

When wood is pressure-treated, chemicals are forced into the wood to create a protective barrier against insects and decay. Fence posts should be pressure-treated and labeled for ground use.

Install Properly

A DIY fence may save you money in the short run, but if the posts are not properly installed you’ll end up with a fence more prone to rot. Make sure you know how to install the posts so they don’t have contact with soil. Or, better yet, hire a professional fence installer.


Protect With Stain

A wood fence needs a coat of protective stain. Since a wooden fence is made from what at one time was a living tree, it will naturally absorb moisture that it once needed to stay alive. In a sense, the wood is like a natural sponge. When stain is applied, the porous texture of the wood is sealed, thereby reducing the amount of moisture absorbed into the wood.

Stain should be re-applied as needed, every one to three years. To test the wood, sprinkle water on the fence and see if it beads up. If the water doesn’t bead up, it’s time to re-apply a protective coat of stain.


Keep The Fence Clean

Keep the fence clean.It’s important to keep a fence clean. For instance, leaves should be raked from the base of the fence and vegetation should be trimmed back. Fungus should be cleaned off.  Also, insect infestations should be removed or treated to prevent damage. Some insects (like termites) will eat wood, and others (like carpenter ants) will build tunnels that weaken the fence.

A wooden fence can be cleaned with a pressure washer on low setting or with a hose and a solution of bleach and water. Although cleaning a fence is never fun, it’s a perfect time to inspect for rot, fungus, or insect infestation. Clean a wood fence annually or as needed.


Replace Rotted Wood

Replace rotted fence posts or boards as soon as possible. Wooden posts or panels that have begun to rot are not only unattractive, but they may reduce the strength of the fence. Also, if rot is caused by fungus, then it’s important to replace the wood to help prevent the rot from spreading.

Although wood fence rot is inevitable over time, with proper installation and maintenance you can have a fence that will bring beauty and functionality to your home for years to come.
