Practical points for boundary work in Haldens
Replacing a fence on the same line as before
Replacing a fence exactly where the old one stood is generally the lowest-risk approach from a boundary perspective, since it maintains a position both neighbours have already implicitly accepted for years.
It's still worth flagging the planned replacement to a neighbour beforehand, particularly if the new fence will be a different height, material or style to what's there now.
Where the old fence's exact line is unclear because it has leant or shifted over time, marking out the intended new line and briefly confirming it with the neighbour avoids later disagreement.
Ground clearance for airflow
Leaving a consistent gap, typically 50-75mm, between the underside of a fence panel or gate and the ground lets air circulate around the bottom rail, which is usually the first part of a timber fence to rot.
That clearance also stops the panel wicking moisture directly from wet grass or standing puddles after rain, something ground contact makes almost unavoidable over time.
On sites with soft or uneven ground, a gravel board fitted below the panel achieves the same protection while keeping the panel itself off the soil entirely.
Covenants restricting side and rear fence height
Some estates carry covenants limiting side or rear boundary fence height below the normal 2m permitted development figure, often to preserve sightlines or a particular street character.
These restrictions are private and enforced separately from planning law, meaning a fence could comply fully with planning rules and still breach the estate's covenant.
It's worth checking the title register for this kind of restriction on any estate where neighbouring gardens seem to share an unusually consistent boundary height.
Checking a panel is square before final fixing
A panel that's racked slightly out of square, even by a small amount, becomes obvious once several are fitted in a row and the tops don't line up evenly.
Measuring both diagonals of the panel frame before fixing, the same check used on gate openings, confirms it's true and worth doing before the first fixing goes in rather than after, when the panel is harder to shift.
A panel forced square against an out-of-true post rather than corrected itself tends to spring back out of shape once the fixings are removed for any future repair, so it's worth addressing the actual cause rather than just clamping it straight.
Sloped gardens and retaining
A sloping plot usually rules out a single level run of panel fencing — the choice is between stepping the fence in even drops between posts, or raking the panels to follow the slope continuously.
Stepped runs look tidier on a steeper gradient and are simpler to repair panel-by-panel; raked runs suit a gentler, more even slope and avoid the small triangular gaps a stepped fence leaves underneath.
Where the drop is severe enough to need a retaining structure rather than just a stepped fence, that's a different job with its own drainage and engineering requirements, not something to bolt onto a fencing quote as an afterthought.
Arris rail mortice joints as a water trap
The mortice joint where an arris rail meets a post is a natural place for water to collect, since the joint interrupts the smooth run of both timbers and can hold moisture in the gap even after the surrounding wood has dried.
This is a common early failure point on older featherboard fencing, where the rail can rot through at the joint while the rest of the rail well away from the post remains sound.
Modern galvanised joist-hanger-style brackets used instead of a traditional mortice avoid this trap entirely, which is why many newer close-boarded fences use bracket fixings even where the visual style still resembles a traditional arris rail panel.
