Garden fencing is one of those tasks that seems straightforward but has more decisions in it than most homeowners initially expect. The choice of material, height, post type and finish all affect how long the fence stands, how it looks over the years, and how much maintenance it needs. Getting these decisions right at installation saves a job that would otherwise recur every few years.
Feather-edge or close-board fencing – vertical overlapping boards on horizontal rails – is the standard for domestic garden boundaries in the UK. It provides full privacy, is reasonably economical, and if put together properly lasts fifteen to twenty years. The critical detail is the posts. Concrete posts and gravel boards with wooden feather-edge panels last significantly longer than fully-timber constructions, because the wood is kept off the ground where rot starts. A concrete post-and-gravel-board system with timber panels between is the sweet spot for cost and longevity in most Bournemouth gardens.
Panel fencing – the pre-made panels of horizontal or diagonal timber slats – are cheaper and quicker to install but shorter-lived. A typical overlap panel lasts eight to twelve years before starting to fail, particularly in coastal locations where salt and wind take their toll. They also look their age quickly, whereas well-built close-board fencing greys evenly and continues to look intentional. For a temporary boundary, panels are fine; for a fence intended to last, close-board is worth the extra investment.
Post choice is the single most important decision. Concrete posts are the modern standard because they do not rot, they take a heavy panel securely, and they can be sourced with slotted faces that accept panels without further fixing. Timber posts, whether tanalised softwood or hardwood, will eventually rot at the ground line no matter how well they are treated – it is a matter of when, not if. Steel post supports set in concrete offer a middle ground where the timber post is held above ground level, but they add cost and can look industrial if not disguised.
Height is a matter of what the fence is for and what the planning rules allow. Two metres is the general permitted development limit at a rear boundary; higher fences typically need planning permission unless behind a hedge or wall. A fence at the maximum permitted height gives full privacy but can dominate a small Garden maintenance visually. In many cases a lower fence topped with a trellis, or a lower fence with a properly-established hedge behind it, gives better privacy over the long term because the planting softens the boundary and grows over the top.
How the timber is treated determines how long the fence lasts. Pressure-treated timber – properly tanalised or Tanalith-treated – resists rot for many years and is the minimum standard for anything intended to last. Untreated timber painted with a wood stain does not achieve the same durability, because the stain is on the surface only. Some suppliers offer double-pressure-treated timber for external use, and where budget allows, it is worth specifying. Redwood is preferable to whitewood because it takes preservative better.
Composite fencing – the plastic-and-wood-fibre composite panels increasingly available in the UK – is a newer option that has genuine advantages. It does not rot, does not need staining or painting, does not warp, and typically comes with warranties of twenty to twenty-five years. The initial cost is roughly twice that of a good timber fence, but the total cost of ownership over twenty years is often lower because the maintenance is essentially nil. Composite fencing looks slightly less natural than well-weathered timber but the gap has narrowed considerably.
Gates deserve more thought than they usually get. A gate takes more punishment than any fence panel because it is being opened, closed and slammed multiple times a day, and the hinges and latch have to withstand that use. Cheap gates from a general fencing supplier tend to sag within a few years because the frame is undersized for the weight of the boarding. A properly braced gate with heavy-duty hinges and a substantial post to hang it from is worth spending on. Getting the gate right on installation saves the annoying job of replacing it before the rest of the fence needs work.
Any garden company fitting fences in Bournemouth worth using will discuss these choices honestly rather than defaulting to whatever they have in the yard. A ten-minute conversation before ordering materials is worth it.
