How to Fix a Fence Panel

Assessing the Damage

Before starting, assess: is the panel itself damaged (cracked, rotten, or broken slats), or has the post failed (snapped, leaned, or the concrete base has lifted)? Panel replacement is straightforward. Post replacement requires concrete removal and is more involved.

Replacing a Fence Panel

Standard UK fence panels are 6ft wide. Panels slot into U-shaped metal clips or channels in the fence posts. To remove a damaged panel: lift it up and out of the bottom channel, then angle it out of the top.

Fitting a New Panel

Fit the new panel in reverse: angle the top into the upper channel first, then lower the bottom into the lower channel. The panel should fit snugly. Use a rubber mallet to tap into place if needed.

Fixing a Leaning Post

A leaning post has usually lost its concrete base due to rot at ground level. Dig around the base to expose the concrete. If concrete is still solid, repack with dry postcrete and brace straight until set (24-48 hours).

Replacing a Fence Post

Dig out the old post and concrete. Posts should be set at least 600mm deep. Fit a new pressure-treated post, check for plumb, add dry postcrete around the base, water it in, and brace straight for 48 hours while it sets.

Preventing Future Damage

Use pressure-treated timber for all repairs. Fit post caps to prevent water ingress. Check and replace any rotten gravel boards. Treat all cut timber ends with end-grain preservative.
