Identify how many palings are affected and where they have detached. Refixing may be possible when the boards and rails remain sound. A moving fence section needs a wider assessment rather than simply adding more screws through the visible boards.
A timber repair and a coating job are separate parts of the scope. Ask whether any finish preparation is included and follow material guidance. Repeated deterioration should prompt a review of exposure and support rather than repeated cosmetic replacement alone.
The board fixing relies on the rail behind it. Soft timber, large splits or failed joints can make a local reattachment unsuitable. Include accessible support photos without dismantling the fence, and identify any uncertainty about the underlying condition.
The agreed service covers suitable local paling reattachment/replacement and compatible fixing review. Exclusions: Post repair (existing intent), major panel/fence replacement, retaining structures, boundary disputes, pool barriers, unstable supports.
