A leaning fence is one of the most common problems homeowners encounter, and the causes can vary widely. In many cases, the issue starts with the fence posts. Timber posts, especially older ones, can rot at ground level over time, leaving them unable to support the weight of the panels. When the base of a post fails, the fence begins to lean, often quite suddenly after a spell of wet or windy weather. Soil movement is another common factor. Heavy rain, poor drainage or recently disturbed ground can cause soil to shift or soften, making posts unstable and allowing the fence to tilt.

On sloping or uneven gardens, fences can also lean if they were not installed with appropriate support. Incorrect post spacing, posts that were not set deep enough or insufficient concrete around the base can all lead to gradual movement. Tree roots can also be a hidden culprit, pushing against posts or undermining the soil beneath them.

Whether the fence can be straightened depends on the extent of the damage. If the panels are in good condition and the lean is caused by one or two failing posts, repair spurs or post replacement can often correct the issue without replacing the entire fence line. A concrete repair spur set alongside the weakened post can restore vertical support, while new concrete footings can stabilise posts that have been undermined by soil movement.

However, if several posts have failed, if the panels or rails are warped or if the entire run appears to be drifting, a full replacement may be the safest and most reliable option. Trying to straighten a severely weakened fence may only provide a temporary fix.

During our assessment we check the alignment, post condition, ground stability and panel structure to determine whether straightening is feasible. We always recommend the most cost effective and long lasting option to ensure your boundary remains safe and secure for years to come.
