Should a Wood Fence Have a Space at the Bottom?

A wooden fence is a popular choice for homeowners who value privacy, security, and aesthetic appeal. However, one important question arises when it comes to installing a wood fence: should it have a space at the bottom? While it may seem like a minor detail, the decision to leave a gap between the bottom of the fence and the ground can have significant implications for the longevity and functionality of the fence. In general, it’s recommended that a wood fence be mounted at least two inches off the ground, with only the posts and rot boards (if you choose to install them) making contact with the ground. This practice helps to prevent moisture absorption, insect infestations, and premature decay of the wood. By understanding the reasons behind this recommendation, homeowners can make an informed decision about whether or not to leave a space at the bottom of their wood fence.

Should There Be a Gap Under Wood Fence?

Additionally, having a gap under your wood fence can also prevent water damage and rot. When the bottom of the fence is in direct contact with the ground, it can absorb moisture, leading to rot and decay over time. By keeping a small space between the fence and the ground, air can circulate freely, allowing the wood to dry out more quickly and reducing the risk of moisture damage.

Moreover, a gap under the fence can help prevent pests from entering your yard. Rats, mice, and other small animals can use the ground as a pathway to access your property. By creating a barrier at the bottom of the fence, you can deter these unwanted visitors and keep your yard and home pest-free.

When the fence panels are in direct contact with the ground, they’re more susceptible to damage from moisture, insects, and rot.

Uneven terrain or settlement over time can cause a fence to become uneven or warped. By allowing for some movement and flexibility at the bottom of the fence through a small gap, you can reduce the risk of damage and ensure that your fence remains upright and level.

How to Create a Gap Under a Wood Fence

Creating a gap under a wood fence can help prevent moisture buildup, improve airflow, and reduce the risk of rot. To create a gap, start by removing the soil near the fence line to the desired depth. Next, place a two-by-four or another suitable sized object along the bottom of the fence, ensuring it’s level. Insert shims if needed to adjust the height. Finally, backfill the gap with gravel or another porous material to allow for drainage. Remember to check your local building codes and regulations before making any modifications to your fence.

There are several effective methods to safeguard the base of a wooden fence and prevent potential issues such as weed growth and termite infestations. By implementing preventive measures like filling the surrounding area with sand, gravel, or mulch, you can effectively deter new growth each season, reducing the need for regular trimming. Additionally, protecting your fence from termite damage can be achieved through various prevention techniques, ensuring the longevity of your fence posts.

How Do You Protect the Bottom of a Wooden Fence?

One way to protect the bottom of a wooden fence is by preventing grass and weeds from growing around it. This can be achieved by first digging out the soil around the fence and then placing a layer of sand, gravel, or mulch. This barrier will help prevent new growth each season, eliminating the need for constant trimming and maintenance.

Another important consideration when protecting the bottom of a wooden fence is to safeguard against termites. These pests can pose a significant threat to fence posts, as they’ve a fondness for devouring newly installed wood. To mitigate this risk, it’s advisable to use termite-resistant materials or treat the wood with a protective solution. Additionally, regularly inspecting the fence for signs of termite infestation, such as small holes or chew marks, can help catch any potential issues early on.

In addition to weeds and termites, moisture can also be a concern for wooden fences. Excessive moisture can cause the wood to rot or warp over time, compromising it’s structural integrity. To prevent this, it’s crucial to ensure that proper drainage is in place. This can include making sure the fence is installed on elevated ground, utilizing gravel or crushed stone below the fence line to improve drainage, or providing adequate spacing between the bottom of the fence and the ground to allow for air circulation.

Furthermore, regular maintenance is key to protecting the bottom of a wooden fence. Periodically inspecting the area around the fence for any signs of damage or wear and tear is essential. Rotting or damaged wood should be replaced promptly to prevent further deterioration. Applying a protective sealant or stain to the wood can also help prolong it’s lifespan by adding an extra layer of defense against moisture, sunlight, and other environmental factors.

Choosing the Right Type of Wood for a Wooden Fence

When it comes to choosing the right type of wood for a wooden fence, it’s important to consider several factors. One of the key considerations is the type of wood that’s most suitable for outdoor use. Common options include cedar, redwood, pine, and cypress.

Cedar and redwood are popular choices due to their natural resistance to rot and insect damage. They also have a beautiful appearance that can enhance the overall aesthetic of your property. Pine is a more affordable option, but it requires regular maintenance and treatment to protect it from decay.

Cypress is another durable wood that’s commonly used for fences. It’s natural oils that make it resistant to rot and decay. However, cypress tends to be more expensive compared to other types of wood.

Regardless of the type of wood you choose, it’s important to select high-quality, pressure-treated lumber that’s specifically designed for outdoor use. This will help ensure the longevity and durability of your wooden fence.

In addition to pressure-treated timber posts, there are several other measures you can take to prevent the bottom of your wood fence from rotting. This includes applying wood preservatives, using a gravel board to create a barrier between the soil and the wood, ensuring proper drainage, and regular maintenance and inspections to identify and address any signs of rot or damage. By implementing these preventative measures, you can extend the lifespan of your wood fence and maintain it’s aesthetic appeal.

How Do I Keep the Bottom of My Wood Fence From Rotting?

One way to prevent the bottom of a wood fence from rotting is to use pressure-treated timber for the posts. Pressure-treated timber undergoes a process where preservatives are forced into the wood, making it resistant to rot caused by soil damage, insects, and other factors. This treatment prolongs the lifespan of the wood, ensuring that the fence remains healthy and sturdy for a much longer period of time.

In addition to using pressure-treated timber posts, it’s also helpful to install gravel boards and concrete foundations. Gravel boards act as a barrier between the soil and the bottom of the fence, preventing moisture from seeping into the wood and causing rot. Concrete foundations, on the other hand, provide a solid base for the fence, keeping it stable and further protecting it from ground-level damage.

Combining these measures creates a strong, durable, and attractive fence that will truly last.

Regularly inspecting the fence for any signs of damage or rot and addressing them promptly can further prevent issues with the bottom of the fence. Applying a protective sealant or stain to the wood can also help to keep it in good condition.

Proper Fence Maintenance and Cleaning Techniques

  • Regularly inspect the fence for any signs of damage or wear.
  • Remove any debris or leaves that may accumulate near the fence.
  • Clean the fence with a mild detergent and water solution.
  • Rinse off the detergent thoroughly with water.
  • For wooden fences, apply a protective sealant or stain after cleaning.
  • Trim any vegetation that may be growing too close to the fence.
  • Check the stability of the posts and repair any loose or leaning sections.
  • Apply a rust-resistant paint or coating to metal fences.
  • Consider using a power washer for stubborn stains, but be cautious not to damage the fence.
  • Regularly maintain the fence to prolong it’s lifespan and enhance it’s appearance.


By keeping a space at the bottom of a wood fence, you can ensure better drainage and avoid contact with moist soil, which can accelerate rotting and decay. This spacing allows for proper air circulation, preventing moisture accumulation and potential damage to the wooden pickets.
