Assessing the Damage to Your Fence Post
Before beginning any work, a thorough assessment of the leaning fence post is crucial. Understanding the root cause of the problem will guide your repair strategy. The most common culprit is often found below the ground.
Inspect the base of the fence post where it meets the ground. Look for signs of wood rot, which you can test by probing the wood with a screwdriver; if the wood is soft and spongy, rot has set in. Also, consider environmental factors like soil erosion or frost heave, where the ground freezes and thaws, pushing the post and its concrete footing upwards and out of alignment.
Check the connection between the leaning post and the adjacent fence panels. Are the screws or nails loose, rusted, or broken? A compromised connection can contribute to the fence leaning and will need to be addressed during the repair. If you’re unsure about the extent of the damage, Richboro Fence offers professional inspections to determine whether a single post repair is enough or if a larger section needs work.
Is It an Isolated Problem?
Look at the other fence posts along the line. If you have multiple leaning fence posts, this could indicate a systemic issue with the original installation, such as posts not being set deep enough or an inadequate concrete footing for your soil type. In some cases, pressure from a failing retaining wall nearby can cause the ground to shift, impacting the stability of your entire fence.
On community forums like the Home Improvement Stack Exchange, homeowners often discuss whether to fix one post or address the entire fence. If more than a quarter of your posts are unstable, a full replacement might be more cost-effective in the long run. Analyzing the scope of the fence repair now will save you time and frustration later—and if the project feels too big to tackle, Richboro Fence can provide a full installation or targeted repairs to get your fence straight and secure again.

Choosing the Right Concrete Mix
The type of concrete mix you choose can impact the durability and speed of your fence repair. For this job, a quick-setting concrete mix is often recommended because it hardens rapidly, allowing you to complete the project in a single afternoon. Standard concrete mix is another option; it is typically stronger but requires a longer curing time, often 24–48 hours, before it can bear any weight.
Before you pour concrete mix, carefully read the manufacturer’s instructions. Different products have specific water-to-mix ratios and setting times. Getting this right is fundamental for a stable and long-lasting repair.
Removing the Old Post and Footing
This is often the most labor-intensive part of the repair. Start by carefully detaching the fence panels from the leaning fence post. Use a drill or the back of a hammer to remove the fasteners, and gently set the panels aside where they will not be damaged.
Next, begin digging around the base of the post to expose the old concrete footing. You will need to create a hole wide enough to work in, typically about twice the diameter of the footing itself. Continue digging until the entire concrete block is exposed.
Once excavated, you can attempt to wiggle the post and footing out of the hole. If it is too heavy, you may need to break up the old concrete with a sledgehammer or digging bar. If the wood post is rotted but the footing is stable, an alternative is to cut the post flush with the concrete and install a metal post mender, though removing the old footing is the better long-term solution for a fence lean problem.
Preparing the Hole for the New Post
A properly prepared hole is the foundation of a stable fence post. The general rule is that one-third of the post’s length should be buried in the ground. For example, a 6-foot tall fence section should have posts that are 9 feet long, with 3 feet set into the ground.
The hole’s diameter should be about three times the width of the fence post. This provides ample room for the concrete mix to surround the post, creating a solid anchor. If the old hole is not deep or wide enough, now is the time to expand it with your post-hole digger.
Pour a 6-inch layer of gravel at the bottom of the hole. This improves drainage, preventing water from pooling around the base of the wooden fence post, which is a primary cause of wood rot. Tamp the gravel down firmly to create a solid base.
Repositioning and Bracing the Post
Place the new or salvaged fence post into the center of the prepared hole. Use your post level on two adjacent sides of the post to ensure it is perfectly plumb, meaning it is perfectly vertical. A critical level check at this stage prevents you from setting a crooked post in fresh concrete.
To keep the post steady while the concrete sets, you must brace it. Drive two wooden stakes into the ground a few feet away from the hole on opposite sides. Use 2x4s to connect the stakes to the fence post, screwing them in place temporarily.
Adjust the braces as needed until the post is perfectly straight and cannot wobble. Many DIY enthusiasts on forums share tips on bracing, but if you want it done quickly and precisely, Richboro Fence’s experienced team can ensure perfect alignment before the concrete is poured.
Mixing and Pouring the Concrete
Now it is time to pour concrete. Follow the directions on the bag of your chosen concrete mix, adding water to the dry powder in a wheelbarrow or bucket. Stir thoroughly until you achieve a consistent, lump-free mixture, similar to thick oatmeal. Carefully shovel or pour the wet concrete into the hole around the post. Fill the hole completely, but stop about 3–4 inches from the ground surface. As you fill the hole, use a stick or trowel to poke the concrete, which helps to remove any trapped air pockets that could weaken the footing.
Once the hole is filled, shape the top of the concrete with your trowel to create a slight dome or slope that directs water away from the wood fence post. This technique, known as crowning, is an important step in preventing future moisture damage.
A Note on Sharing Your Work
Many find it helpful to document their projects. If you’re creating a guide for a blog or sharing your success online, clear photos of each step are invaluable. You might even find that sharing your answer activity earns you recognition on some platforms.
Finishing Touches and Curing
Let the concrete cure according to the package instructions. Quick-setting concrete may be firm enough to support the post in a few hours, but it takes a full day or more to reach maximum strength. Do not remove the braces or reattach fence panels until the concrete is fully set.
Once the concrete has hardened, you can remove the 2×4 braces. Fill the remaining space at the top of the hole with soil and compact it firmly. Now you can reattach the fence panels to the newly secured post, using new exterior-grade screws for a strong connection.
Finally, give your entire fence a once-over. Check that everything is level and secure. This fence post repair should leave your fence looking straight and sturdy, ready to stand strong for years to come.
Maintaining Your Repaired Fence Post
Proper maintenance will extend the life of your repair and prevent future issues with leaning fence posts. Regularly inspect the base of the post, especially after heavy rain or winter thaws. Ensure that soil and debris are not piling up against the wood, as this can trap moisture.
Apply a quality wood preservative or sealant to your wooden fence every two to three years. This protects the wood from moisture, UV rays, and insect damage. For a cedar fence, using a specific cedar-friendly stain will help maintain its natural color and resilience. Richboro Fence also offers maintenance services to keep your fence in top shape year-round.
If you see new signs of a fence leaning, address them immediately. A small adjustment is much easier to handle than a major post repair. A proactive approach is the best way to keep your entire fence in great condition.
When to Call a Professional
While fixing a single leaning fence post is a manageable DIY project, some situations are better left to professionals. If your entire fence is leaning or you have multiple damaged posts, it could signal a larger structural problem. Pros have the heavy-duty equipment and experience to handle complex repairs efficiently.
You should also consider calling an expert if your fence is located on a steep slope or is adjacent to a large retaining wall. These scenarios require specialized knowledge to ensure a safe and lasting solution. Additionally, if the fence marks a property line, involving a professional can help avoid disputes with your neighbors. Richboro Fence has experience with both residential and commercial fencing challenges, making them a reliable choice for tricky repairs or complete replacements.
