Overview
A broken fence panel compromises privacy and security. This guide covers repairing or replacing a damaged fence panel.
Step-by-Step Fix
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Inspect the fence to determine the extent of the damage. Check the posts, rails, and panels. If only the panel is damaged the posts may be fine. If the posts are also damaged they will need to be replaced. Place a bucket or tarp under the area to catch debris.
- If the panel is broken but the posts are sound remove the damaged panel. Use a pry bar to carefully remove any nails or screws holding the panel to the posts. Lift the panel out and set it aside.
- Check the fence posts for rot or damage. Push the posts to test for movement. If a post is loose dig around the base and add concrete to secure it. If the post is rotted it must be replaced. Dig out the old post and set a new one in concrete.
- Purchase a replacement fence panel of the same size and style. Fence panels come in standard sizes. Measure the gap between the posts to determine the correct panel size. If you cannot find an exact match you may need to trim the panel.
- Position the new panel between the posts. Check that it is level and sits flush against the posts. If the panel is slightly too large plane or sand the edges to fit. Do not force the panel into place as this can crack the wood.
- Secure the panel to the posts using galvanised fence panel brackets or screws. Drive screws through the panel into the posts at the top, middle, and bottom. Use two screws at each point for stability.
- If the fence rails are also damaged replace them. Rails are the horizontal pieces that support the panel. Remove the old rails and install new ones. Secure them to the posts with screws.
- Apply a wood preservative or fence paint to the new panel and any exposed wood. This protects the wood from rot and weather damage. Allow the preservative to dry completely before exposing to rain.
- Test the fence by pushing on the panel. It should feel solid and not move. If the panel is still loose add more screws or brackets. Check that the panel is straight and level.
- To prevent future damage check the fence annually for signs of rot or loose fixings. Tighten any loose screws and replace damaged panels promptly. Applying preservative every two to three years extends the life of the fence.
Common Symptoms & Diagnostic Resolutions
Review the common error codes and operating symptoms below to quickly identify the root cause of the fault before ordering replacement parts.

| Post is rotted | Wood rot from ground contact | Replace the post. Set the new post in concrete to prevent rot. |
| Panel does not fit | Wrong size panel | Measure the gap between posts. Buy a panel that matches or trim the panel to fit. |
| Fence leans | Posts not secure or ground movement | Dig around the posts and add concrete. Check that posts are set deep enough. |
