Why Fences Lean and How to Fix Them

Fences serve a crucial role in our homes, providing privacy, security, and aesthetic appeal. However, over time, many fences develop a common issue – they start to lean. A leaning fence not only compromises its functionality but can also be an eyesore. In this article, we’ll explore the reasons why fences lean and provide practical solutions on how to fix them.

5 Reasons Why Fences Lean

1. Weathering and Decay: Post rot is the most common reason that a fence starts to lean. Exposure to the elements, particularly moisture, can cause wooden fence posts to rot over time. As the wood weakens, it becomes less capable of supporting the fence’s weight, resulting in a lean

2. Improper Installation: Fence installation is a skilled job, and if not done correctly, it can lead to leaning fences. Incorrect spacing between posts, inadequate bracing, or using the wrong type of fasteners can all contribute to this issue.

3. Inadequate Post Depth: Properly installed fence posts should be buried deep enough to provide stability. If the posts are not set at the appropriate depth, they may not be able to support the weight of the fence, leading to leaning.

4. Tree Roots: Nearby trees can also be a source of trouble. As tree roots grow and expand, they can disrupt the soil around fence posts, causing them to shift or become destabilized.

5. Foundation Problems: Uneven or shifting ground can cause the fence posts to become unstable. This is especially common in areas with clayey or sandy soil, which can expand and contract with changes in moisture levels.

How to Fix a Leaning Fence

Now that we understand why fences lean, let’s dive into how to fix this common problem.

  1. Assess the Damage: Begin by identifying the cause of the lean. Check for rot, loose fasteners, and the depth at which the posts are set. This will help you determine the appropriate solution.
  2. Realign the Fence: If the fence has only a slight lean, it may be possible to correct it by gently pushing or pulling the fence back into position. Use a level to ensure it’s straight, and then secure it temporarily.
  3. Replace Damaged Posts: For posts that are rotted or otherwise damaged, you’ll need to replace them. Dig out the old post, ensuring you remove any remaining fragments, and replace it with a new one set at the correct depth and concreted securely into place.
  4. Fence Bracing: Installing braces can help stabilize your fence. These braces can be diagonal supports on the leaning side of the fence. To have them support a fence in winds that switch directions these braces need to be secured to a large stake n the ground, the house, tree, or other item that is large enough and strong enough to hold the weight of the fence in the winds. Another option is to galvanized pipe, Postmaster posts, or T-posts driven into the ground attached to the fence.
  5. Tree Root Management: If tree roots are causing the problem, consider trimming or removing the offending roots, taking care not to damage the tree in the process.

Yearly Fence Maintenance

A year inspection and maintenance in the fall each year will help you prevent your fence from leaning or falling down in a winter storm. During your inspection you should look at and “feel” the fence. With your eyes you can note for repair things like missing nails, warped boards, rail rot, and leaning of the fence. To be even more preemptive you need to “feel” the fence. As you walk down the fence line push on each post with one hand. If the post moves or feels squishy, this post should be noted for further inspection and probable replacement. Fence posts should be stout and not move. By pushing on the posts you will be able to repair or replace fence posts BEFORE they start leaning and this help extend the life of your overall fence. Fixing the post issue before your fence starts leaning is much like having your car repaired when it starts to make a weird noise rather than waiting till you are broken down on the side of the road. Proper maintenance will ensure that you do not get caught with your fence down!


A leaning fence is not just an aesthetic concern but also a functional one. Fortunately, understanding the reasons behind fence leaning and knowing how to fix it can save you time and money in the long run. Whether you need to realign, replace, or reinforce your fence, addressing the issue promptly will ensure that your fence remains a reliable and attractive addition to your property. Remember, proper installation and regular maintenance are key to keeping your fence standing tall for years to come.
