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.
Post movement or failure belongs to a different assessment and may exceed a small repair. Describe leaning or movement in the whole section. Paling work is bounded to local boards on suitable support, not a way to conceal an unstable fence.
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 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.
