A repair may depend on reaching the fixing side of the fence. Explain available access and any neighbour or property-manager permission required. Do not assume entry to another property is included merely because the damaged board faces your garden.
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.
Measure the visible width and thickness where safe and show the board profile. Replacement timber can differ from weathered material in colour and texture. Discuss finish expectations before assuming a new paling will immediately blend with the older fence.
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.
