Replace a fence panel

Remove the damaged fence panel, check the posts and gravel board, then fit and secure a matching replacement panel.

FP-01Measure up and buy your new panelMeasure the width and height of the panel you're replacing, plus the gap between posts. Standard panels are 1.83m wide, in heights from 0.9m to 1.8m, but older fences can be non-standard, so measure rather than guess. If you're replacing like-for-like there's normally no issue, but if you plan to make the fence taller, check first: fences over 2m generally need planning permission, and over 1m if the fence is next to a road and forms the boundary of a driveway, front garden or public path.

KNOW THE RULES

Fences over 2m high (or over 1m next to a road) may need planning permission under permitted development rules. Replacing an existing fence at the same height is normally fine.

FP-02Check who owns the fence and let your neighbour knowIf the fence sits on a shared boundary, it's good practice to tell your neighbour you're replacing it, especially if you need brief access to their side. There's no general rule that says who owns a boundary fence — check your property deeds if you're unsure, but for a straightforward like-for-like swap this is usually just a courtesy, not a legal requirement.

FP-03Clear the area and gather your toolsClear plants, pots and debris from both sides of the fence. Wear gloves — old panels often have splinters, rusty nails or staples. Have a claw hammer, pry bar, cordless drill/driver, spirit level and a bag for waste ready before you start.

FP-04Remove the old panelIf the panel is screwed or nailed to timber posts, remove the fixings from both ends and lift the panel out. If it sits in grooved concrete posts, it usually just lifts straight up and out — get a helper to support the other end so it doesn't twist and jam. Set the old panel aside for disposal.

FP-05Check the posts and gravel boardLook at both posts for rot, cracking or movement — push each one to check it's still firm in the ground. A wobbly timber post can often be stiffened with a bolt-on post support spike rather than fully replaced. Check the gravel board (the horizontal board along the bottom) too, as it takes the most ground moisture and often needs replacing at the same time as the panel.

FP-06Trim the new panel to fit if neededIf your gap is slightly different from a standard panel size, trim the panel with a hand saw or circular saw, cutting a small amount evenly from one or both edges. Support the panel firmly on trestles while you cut, and wear eye protection.

FP-07Fit the new panelFor concrete posts, lift the panel and slide it down into the grooves on both posts. For timber posts, hold the panel in position, check it's level with a spirit level, then screw galvanised panel clips (or fence brackets) top and bottom on both sides to hold it in place.

FP-08Fix the panel securelyDrive screws through the clips or brackets into the panel frame, not just the thin slats, so the fixing holds real weight. Check the panel is square and doesn't rock in strong wind by pushing gently on both faces before you finish.

FP-09Treat cut edges and tidy upBrush a wood preservative over any freshly cut edges of the panel or gravel board to stop them rotting early. Clear off-cuts, old nails and the removed panel, and dispose of the timber at your local household waste site if it's treated wood.
