    | by Holly Wood

    If you find yourself in a situation where you need to increase the height of your existing fence, whether for added privacy, security, or aesthetic reasons, you’re in the right place.

    Extending the height of your fence can be a relatively straightforward DIY project, and there are several creative ways to achieve it.

    In this comprehensive guide, we will explore various methods and techniques to extend your fence height successfully.

    Assessing the Need to Extend Fence Height

    Before you start planning and executing your fence height extension project, it’s essential to assess why you want to extend your fence.

    Understanding your goals will help you choose the most suitable method and materials for the job.

    Enhancing Privacy and Security

    Adding height to your fencing can provide a greater sense of privacy and security for your property.

    It can help deter prying eyes and unwanted intruders while creating a more secluded and comfortable outdoor space.

    Meeting Height Restrictions and Planning Permission

    In some areas, there may be height restrictions for fences. Make sure to check local regulations and obtain any necessary planning permission before embarking on your fence extension project. Failure to do so could result in legal issues and fines.

    Aesthetic Improvements

    Making your fence taller can also be purely for aesthetic purposes. It can enhance the overall look of your property, create a backdrop for garden features, or simply update the appearance of your yard.

    Methods for Extending Fence Height

    Now that you’ve determined your reasons for extending your fence height, let’s explore various methods to achieve this goal.

    Using Fence Toppers

    Fence toppers, also known as fence extensions, are pre-made fence panel components designed to attach to the top of your existing fence.

    They are available in various materials, including wood, metal, and plastic, and can easily increase your fence height by 1 to 2 feet.

    To install a fence topper, you’ll typically need screws or brackets and a drill.

    Adding Trellis Panels

    Trellis panels are an excellent choice if you want to combine increased height with an opportunity for climbing plants to grow.

    You can attach trellis panels to your existing fence using screws or nails. Attaching trellis panel not only adds height but also creates a visually appealing living fence when covered with climbing plants.

    Installing Post Extensions

    If you have concrete posts supporting your existing fence, you can extend the height by attaching post extensions.

    These post extenders fit securely over the top of your existing posts and provide a platform for attaching taller fence panels or other materials.

    Ensure the extensions are securely fastened to maintain stability.

    Replacing Existing Boards with Taller Ones

    For fences made of wooden panels or boards, you can simply replace the existing boards with taller ones.

    This method is relatively straightforward but may require some woodworking skills. Ensure the new boards are securely attached to the fence frame.

    Utilising Concrete Posts

    If you have concrete posts, you can attach taller fence panels directly to them using screws or brackets.

    This method provides a sturdy and long-lasting solution for extending your fence height. Just make sure the panels are well-anchored to the posts.

    Creating a Living Fence

    Another creative way to extend your fence height is by planting climbing plants along the fence line.

    While this won’t add instant height, over time, these plants can grow and create a natural screen for added privacy and aesthetics.

    Materials and Tools You’ll Need

    Depending on the method you choose, you’ll require different materials and tools for your fence height extension project. Here’s a general list of what you may need:

    • Fence toppers or trellis panels
    • Post extensions or taller fence panels
    • Screws, nails, or brackets
    • Drill or screwdriver
    • Saw (if replacing boards)
    • Climbing plants (if creating a living fence)
    • Concrete mix (if using concrete posts)

    Steps to Extend Your Fence Height

    Now that you have chosen a method and gathered your materials, let’s outline the general steps to extend your fence height:

    1. Prepare Your Existing Fence: Inspect your existing fence to ensure it is in good condition and that it can support the additional height. Make any necessary repairs before starting the extension.
    2. Measure and Plan: Measure the desired height extension and mark it on your existing fence. Plan the placement of fence toppers, trellis panels, or post extensions to ensure even spacing.
    3. Attach the Extensions: Depending on your chosen method, attach the fence toppers, trellis panels, or post extensions using screws, nails, or brackets. Ensure they are securely fastened to prevent wobbling or falling.
    4. Plant Climbing Plants (if applicable): If you’re creating a living fence with climbing plants, plant them at the base of the fence and provide proper support for them to grow.
    5. Finishing Touches: After extending the fence height, you may want to paint or stain the new components to match the existing fence for a cohesive look.
    6. Maintain Your Fence: Regular maintenance, such as painting, staining, and trimming climbing plants, will help keep your extended fence in good condition and looking its best.

    Considerations and Tips

    • Always check local regulations and obtain any necessary planning permission before extending your fence height.
    • Ensure the extended fence is structurally sound and securely anchored to prevent safety hazards.
    • Choose materials that match the style and design of your existing fence for a seamless appearance.
    • If you’re not comfortable with DIY projects, consider hiring a professional to ensure the job is done correctly.
    • Communicate with your neighbours if the extended fence may affect their views or property.


    Extending the height of your fence can be a rewarding project that enhances your property’s privacy, security, and aesthetics.

    Whether you opt for fence toppers, trellis panels, post extensions, or a combination of methods, careful planning and proper execution will ensure a successful outcome.

    Remember to follow local regulations, maintain your fencing, and enjoy the benefits of your taller, more impressive fence. With the right materials and a bit of effort, you can transform your yard into a haven of privacy, shade, and beauty.
