Why the bottom board fails first
The lowest part of any fence meets damp soil, wet turf, mower spray and general knocks. It is no surprise that this is where timber rots first. A gravel board is designed for that job, and when it reaches the end of its life, the panel above is often still perfectly sound. If you are unsure which parts are sound, press the timber with a screwdriver tip and note where it feels soft.
If the fence has no gravel board, the bottom of the panel itself takes the abuse. Then the panel may be soft along the base while the top half looks fine. In both cases, it is worth looking closely before deciding what has to be replaced, because a small repair can save a large job. Be wary of a quick fix that hides rot, because moisture will carry on spreading underneath.
How a board is swapped on its own
With a fence built to take them, gravel boards sit between the posts, held in slots or fixed with cleats. The panel rests on top. To change one, the panel is lifted slightly or supported, the old board is removed, and a new one is fitted. In many cases no digging is needed.
This depends on how the fence was built and on the state of the posts and panel. If the panel has rotted down into the board, or the posts are loose, a simple swap may not be enough. A fencer can usually tell from a photo or a quick look which of these you have. It is worth taking a photo before and after, so you can see how the fence is holding up.
Keeping the lawn edge tidy afterwards
Once the new board is in, keep soil and turf away from the panel. Cut a clean line along the lawn and keep any soil lower than the top of the board. Wet ground and long grass against it will shorten the life of even a good board. Sharing those findings makes it much quicker for a fencer to say what can stay.
For gardens in terraces and newer developments, where space is tight, mow and trim along the board in the same way each time. A neat edge is easier to maintain than a rough one, and it makes any future problem simple to spot early. Small, regular checks along the fence save larger jobs later on.
Quick tips
- Look at the bottom of the panel as well as the gravel board before deciding what to replace.
- Ask whether the existing panel can be kept. Often only the board at the base needs changing.
- Keep turf and soil below the top of the gravel board so the panel above stays dry.
- If posts are loose or leaning, mention it, because a new board will not fix a failing post.
