To freshen up your outdoor space, you can replace your old damaged fence. Damaged wire mesh or a weathered fence can not only detract from the appearance of your property, but also compromise your security and privacy. Replacing a garden fence is a project that is accessible even to occasional DIYers, provided you follow a few essential steps.
The current condition of your fence
While some damage can be repaired without requiring a full replacement, replacement is sometimes necessary.
First check the posts, which form the load-bearing structure of your fence: if they are in good condition, you may be able to keep them and simply replace the wire mesh or panels.
If the foundations are unstable or the posts are rusty or rotten, a full replacement is required. This initial assessment will allow you to set a more accurate budget and determine the scope of the work to be carried out.
Choose the type of fence that suits your needs
The market now offers a wide range of options for marking out your garden, each with its own specific advantages:
- Simple wire mesh: affordable and easy to install, ideal for marking boundaries without blocking the view
- Rigid panels: sturdy and durable, available in different heights
- Wooden fence: attractive and natural, requiring regular maintenance
- Privacy screens and screening: perfect for preserving privacy
- Composite fence: combining aesthetics and strength, with minimal maintenance
Consider the environment of your garden, local regulatory constraints, and your specific security and privacy needs to make the best choice.
Take accurate measurements for your new installation
Accurate measurements are crucial to the success of your project. Measure the total length to be fenced and determine the number of posts required based on the recommended spacing for the type of fence chosen. Do not forget to plan the location of any gates and pedestrian gates.
If you keep the old posts, check their spacing and make sure it is compatible with your new fencing system. For sloping ground, plan specific adjustments such as stepped panels or a stair-step installation.
Prepare the ground before installation
Ground preparation is a key step in ensuring your fence lasts. Start by completely removing the old installation if necessary. Thoroughly clear the work area by removing roots, stones, and other obstacles that could hinder installation.
For new posts, dig holes at least 40 cm deep (more in windy regions). The ideal diameter generally corresponds to three times that of the post. This depth will ensure optimal stability in bad weather and prevent future settling.
Install the posts correctly, the key element of your fence
The posts are the backbone of your installation, and their placement determines the overall strength. Use a spirit level to ensure they are perfectly vertical. For optimal fixing, pour concrete into the holes and let it dry for at least 48 hours before continuing the installation.
Post alignment is essential: stretch a string between the first and the last to maintain a perfectly straight line. For corners, use specific posts that will allow a clean, solid connection. This careful step will determine the final look of your fence.
Install the wire mesh or panels between the posts
Once the posts are fully stabilised, you can proceed with the installation of the wire mesh or panels. For flexible wire mesh, use tension wires and strainers to achieve a well-tensioned surface. Fix it to the posts using fasteners suited to the material.
For rigid panels or slatted screens, follow the manufacturer’s specific instructions regarding fixings. Generally, they are attached using clamps or slot directly into grooves provided on the posts. Regularly check the horizontal alignment of the panels for a professional finish.
