Timber fence posts rot from the bottom up. The section buried in the ground sits in constant contact with moisture and soil, and in the absence of proper preservative treatment, this section fails first. The post may look sound above ground while being completely compromised at the base. Once the timber loses structural strength at the footing, the post will begin to lean under the lateral load of the fence panels — especially in wind.
A fence post should be buried to at least a third of its overall length. For a standard 1.8m fence, that means a post at least 600mm into the ground — and in clay soils or exposed positions, deeper is better. Posts that were installed too shallow, or set directly into soil without concrete, will never hold long-term. This is one of the most common causes of fence failure we see on site across Worcestershire and the Cotswolds.
Across Worcestershire, Gloucestershire, and the Vale of Evesham, clay soil is the dominant ground type. Clay expands when it absorbs water and contracts when it dries out. This continual movement applies force to fence post bases, gradually working them loose from their concrete setting. Posts that were installed correctly can still begin to fail after ten to fifteen years simply because the ground has moved enough times to fracture the concrete footing.
Even correctly installed posts can be loosened by repeated exposure to high wind. Fence panels act as sails, and in an exposed garden in Worcestershire or the Cotswolds, winter storms apply substantial lateral force to the entire fence line. Posts that have started to loosen for any reason will fail quickly in a storm.
