Installing Wood Fencing Panels with Existing Wood Fence Posts

Quck answer

To install wood fencing panels using existing wood fence posts, follow these steps:

1. Measure the length of the existing fence posts and purchase wood fencing panels of the same size.

2. Remove any old panels or damaged sections from the existing fence.

3. Attach the new wood fencing panels to the existing fence posts using nails or screws. Make sure they are securely fastened.

4. Check that the panels are level and adjust as necessary.

5. Repeat the process for each panel until the entire fence is covered.

6. Optional: Stain or paint the new panels to match the existing fence for a cohesive look.

By following these steps, you can easily install wood fencing panels using existing wood fence posts.


Prefabricated fencing panels provide a convenient and effortless way to construct a fence. These panels are available in various materials such as wood, vinyl, composites, and even metal (although metal panels are best suited for metal posts). Attaching them to wooden posts that are already set in concrete is a simple process. The most challenging part of the job is setting the posts. However, if you have removed old fencing and want to reuse the posts, this task becomes easier.

However, there is a small issue. The posts need to be spaced accurately for the panels to fit correctly. Typically, panels are available in lengths of 6 and 8 feet, so the post spacing should match this measurement. If the spacing is wider than the panels, you can potentially adjust the posts by using shims. However, if the spacing is narrower and you cannot move the posts, you will need to modify the panels, create your own panels, or consider using a different type of fencing.

Straight and Sturdy Posts are Essential

Fencing panels tend to be heavy, often heavier than the previous fencing material. Additionally, they act as effective windbreaks. Hence, the fence posts must be strong enough to support them. Moreover, the posts need to be straight because any deviation will result in gaps along the sides of the panels. If your existing posts meet the criteria of being strong, straight, and accurately spaced, then you are ready to proceed. However, it is likely that your existing posts will not meet these requirements.

If the posts are set in concrete and some are leaning while others are unstable, and the spacing is slightly off, it may be better to construct a slat-and-rail fence rather than attempting to install panels. This way, you can cut the rails to fit accordingly. However, if the posts are set in soil, you can remove them and dig a hole for each post using a post-hole digger or an auger. Each hole should have a diameter of approximately 12 inches and be deep enough to sink the post by at least one-third of its length. This may result in shorter posts than before, but they can still be utilized.

Set Posts Individually During Panel Installation

Posts should be set in concrete to provide support for the fencing panels against wind. Start the installation process by setting the first corner post vertically and level in concrete. Allow the concrete to set. Measure the width of the first panel, and then place the next post in its hole with its facing edge precisely at the same distance from the edge of the first post. Secure the post in place using braces, install the panel, and proceed to the next post, repeating the same steps. Do not backfill any additional posts at this stage.

Once you have completed the line of fencing up to the opposite corner, return and fill each hole with concrete. Before pouring the concrete, double-check the level of each post to ensure the fence is not leaning backward or forward. This method guarantees the correct post spacing and allows for panels of different widths.

How to Connect the Fencing Panels

To securely attach wooden fencing panels to posts, the most convenient method is to use screws. Begin by cutting two small pieces of scrap wood to serve as supports. Screw these supports to the bottom facing edges of adjacent posts. Next, stretch a line level between the supports and ensure that the bubble is centered. If the ground is uneven, the supports may be at different heights on the posts. Place the panel on top of the supports and use 2 1/2-inch exterior screws to fasten the panel to the posts.

If you are installing vinyl or composite panels, they will typically come with brackets for attaching them to the posts. If not, you can purchase the brackets separately. Each panel has a top and bottom rail, and some may have a middle rail as well. Therefore, you will need two or three brackets per panel per post. Space the brackets evenly apart, aligning them with the rails. Use a line level to ensure that all brackets are at the same height as the corresponding ones on the adjacent post. Screw the brackets securely to the posts. Finally, place the panel in the brackets and drive screws through the holes in the brackets to secure it in place.
