How To Raise The Height Of A Vinyl Fence

If you want to increase the height of your vinyl fence, you can do it yourself without too much difficulty. However, for taller or heavier fences, it’s recommended to have a friend assist you with the lifting. Raising a vinyl fence is typically cheaper, easier, and quicker than replacing the entire fence.

The good news is that you usually don’t need to demolish your existing fence to increase its height. Vinyl fences are typically made up of sections called panels that are attached to posts. By using lattice panels or similar materials along with u-channels, you can effectively raise the height of your vinyl fence. There are three main methods to achieve this, and the necessary materials can be found at most hardware stores, specialized fence suppliers, or online retailers.

In most cases, the first step in raising a vinyl fence is to extend the posts, as they provide the necessary support and stability for the panels. This step should be done carefully, as failing to properly support the fence panels can lead to a short-lived fence.

One option is to install the new extended fence panel directly on top of the existing fence, creating additional height. This method allows for creativity in choosing the materials for the extension, as the original lower section will consist of the factory-made vinyl fence panels, which serve as the base for the new upper section.

There are various fence kits available that can cater to your specific needs, whether you’re looking to increase privacy, keep your dog in the yard, or prevent deer from entering your property.

We’ll explore several methods and techniques for raising the height of a vinyl fence, allowing you to choose the one that best suits your requirements.

Fence Kits for Extending Vinyl Fence Height

Adding height to your vinyl fence is a simple and cost-effective process with the help of fence kits. These kits typically include all the necessary components, except for the tools, making the installation process straightforward for homeowners with basic power tools.

Reasons for Raising a Vinyl Fence

There are various reasons why you might want to increase the height of your vinyl fence. However, it’s crucial to choose a kit that aligns with your specific goals. For example, fence-raising kits designed to keep deer out differ from those meant to enhance privacy. Selecting the wrong kit may result in a taller fence that fails to serve its intended purpose.

Choosing the Right Kit

Once you’ve identified the appropriate vinyl fence-raising kit for your project, carefully read the instructions provided. While most kits are user-friendly, some may have specific installation requirements. Assembling fence extensions is generally as simple as putting together furniture, but working with taller fences can be more challenging. If you need to use a ladder, be sure to follow proper safety guidelines.

When selecting a fence kit, consider factors such as color, material, and style. The goal is to ensure that the extension is both functional and aesthetically pleasing. As the fence height increases, the top portion becomes more noticeable, so it’s important to choose a kit that complements your existing fence. Avoid extensions that look like an afterthought; instead, opt for colors and styles that seamlessly blend with your current fence for a more natural appearance.

Where to Find Fence Kits

Home Depot offers a wide variety of vinyl fence products, making it an excellent starting point for your search[4]. If you’re looking for something specific, you can also explore online retailers that specialize in fencing materials[1][5].

By following these guidelines and carefully selecting the right fence kit, you can successfully increase the height of your vinyl fence while maintaining its aesthetic appeal and functionality.


Post Extensions for Raising Vinyl Fence Height

Using post extensions is an excellent way to increase the height of your vinyl fence.

Types of Post Extensions

Fence post extensions are available as individual units or as part of a kit. It’s crucial to choose an extension that matches your existing posts in terms of size, style, and color. Vinyl fence posts typically come in widths of 4, 5, or 6 inches[14]. Post extension kits are also available in various lengths, as some areas of your fence may require a foot of additional height, while others may only need six inches[2].

Adjustable Height

Many fence post extension kits allow you to adjust the height according to your specific requirements[2].

Additional Components

In addition to extending the fence posts, you’ll also need to fill in the new height with an extended fence panel. This can be achieved by using materials like vinyl lattice along the length of the fence[2][17].

Installation Process

  1. Determine the number of post extensions needed for your project. Not every post may require an extension, depending on your specific goals. For example, you might want a higher fence in your backyard compared to your front yard[2].
  2. Extend the post extensions to the desired height, following the instructions provided with the kit[2].
  3. Install the vinyl lattice or other chosen material over the existing fence panels, using the rails of the post extensions[2][17].

Choosing the Right Kit

When selecting a fence post extension kit, consider factors such as color, material, and style to ensure that the final result is both functional and aesthetically pleasing. As the fence height increases, the top portion becomes more noticeable, so it’s important to choose a kit that complements your existing fence[2]. Aim for a seamless, natural appearance rather than an obvious add-on.

Where to Find Post Extensions

Many home improvement stores, such as Home Depot[16] and Lowe’s[12], offer a wide range of vinyl fence products, including post extensions. You can also explore online retailers that specialize in fencing supplies[1][4][10].

By carefully selecting the appropriate post extension kit and following the installation guidelines, you can successfully raise the height of your vinyl fence while maintaining its structural integrity and visual appeal.


U-Channel To Add Lattice To Existing Fence

The U-channel is a u-shaped piece of material that is typically used in a range of outdoor situations. Plastic, vinyl, or metal are usually used to make them – but mostly galvanized steel is used. It is recommended that you buy the type that corresponds to the material of your fence. You can use this approach as a cheap and easy way to extend the height you want on your existing vinyl fence.

Door frames, windows, and other places around the home can also be wrapped with U-channel. So if you’re shopping at Home Depot or Lowe’s, you might find it on the doors or siding aisles, not in the fence aisles.

If you’ve ever worked with siding then you’ll be familiar with how u-channel works. Similar to the J-channel you buy for windows and doors. The only difference is that lattice or some other fence material will be used instead of siding slipping into the channel.

U-channel is primarily used to build a frame around materials like lattice. Plastic sheets or Azek sheets also work well. U-channels are used to create a stronger frame around these flimsy materials.

To support each lattice section, you’ll need four pieces of u-channel cut to the correct size. A 6-inch raise of an 8-foot vinyl fence will require 4 pieces of u channel. There are two 8-foot pieces and two 6-inch pieces. The u-channel frame also needs a piece of lattice measuring 6 inches by 8 feet.

Some glue and screws should be used to secure the pieces of u-channel together. A very strong bond is formed when the glue dries.

When you have constructed your u-channel frame and attached your lattice or other material, you can secure it to your fence posts. An exterior grade screw or stainless steel screw is recommended. Rust-prone materials should not be used.

Here are some tips on extending a vinyl fence’s height with u-channel:

  1. Measuring vinyl fences with u-channel is always the first step I take. Due to its flimsy nature, u-channels need to be measured.
  2. The u-channel needs to be cut and secured with the appropriate tools. You will need different tools depending on what type of U-channel you are using.
  3. The fence sheet can be framed with u-channel easily.
  4. The panel should be placed between the rails and posts after the sheet is framed with u-channel.
  5. Attach the panel to the railing and support post by screwing through the channel.
  6. Stainless steel or exterior grade screws are recommended.
  7. Measure and cut the u-channel carefully. All the weight of the lattice will be supported by the frame you build.

The U-channel approach is a great way to raise a vinyl fence, but the lattice is also required to fill in the area. The U-channel is used as the mechanism to hold the flimsy lattice firmly in place.

Vinyl Fence Boards

It is possible to secure vinyl boards to the top of a fence by cutting them to length. Due to the lack of large panels, this option requires a lot of work. Hand-cutting and hand-securing are the only ways to secure each piece. It allows you to get creative since it is a very customized option.

First, build a frame using fence boards as with u-channel. Using the example above, if you are raising a vinyl fence section 6 inches, then you should build a frame 6 inches x 8 feet first. The void can be filled with any design after the frame has been constructed. We need to be creative here.

In order to install the frame and panel section on top of your fence, you must build them on the ground first. You should always work on the ground as much as possible – it makes it much easier.

Azek is an excellent material for building the inside panels. As a panel material, it’s great because it’s easy to cut and shape, but not for frames because it is flimsy.

The frame can be made from vinyl boards. Panels can be supported by them because they are stronger.

Ensure the frame is securely attached to the fence and posts. Screws made of stainless steel or exterior grade should be used. You could lose your new fence panel if you don’t secure the connection to the original fence properly.

Raising your vinyl fence: More options

Vinyl fences can be raised in a variety of ways. Be creative and use your imagination. Many people do not find it the most practical solution to purchase a fence-raising kit and match the existing fence.

More unconventional ways to do it follow.

More Ideas:

  • Trellis. It is also possible to raise a fence using a trellis. Plants are supported by trellises, which are wooden frames with bars. Climbing plants look great on top of fences. This helps hide the appearance of a high vinyl fence and makes it blend in with the surrounding landscaping. A huge benefit of climbing plants is that they require little or no maintenance.
  • Trees or hedges. Adding trees or hedge plants will keep your vinyl fence from looking too high if you are planning to raise it for privacy reasons. The same effect as a high fence can be achieved by planting trees or a fast-growing hedge without raising the fence.


The good news is that you don’t have to worry about extending the height of your vinyl fence if you know what you’re doing. You can do it yourself, and it isn’t difficult at all. However, if your fence is high or heavy, it is best to do it with a friend. You can raise a vinyl fence much more easily, cheaply, and quickly than you can replace it. It usually doesn’t involve demolition. Posts are usually anchored into the ground to attach sections of vinyl fence, called panels. Adding post extensions or lattice or some other similar material to u-channels is one way to raise the height of a vinyl fence. It is usually possible to purchase all three methods at any hardware store, fence supply house, or online.

Vinyl fences are usually raised by raising the posts first. Supporting the panels and giving a fence its strength are fence posts. Taking your time is a good idea here. It’s possible to build an attractive fence panel, but if you don’t support it, it won’t last.

By installing the new fence panel over the old one, more height is created. Because it allows for creativity, it can produce a beautiful fence. Factory-made vinyl fence lower sections will be available as your existing base to work from. There is no restriction on what you can do with this new upper area – be creative and find material that works in your situation.

You can probably find a fence kit that fits your needs, whether you want to gain more privacy, keep your dog in the yard, or keep those pesky deer out. But you can also do more of it yourself using the U-channel approach for a more custom solution.
