Six questions in every room
The first is inventory: what is actually here, including the surfaces nobody thinks about such as skirtings, frames, switch plates and the tops of joinery. The second is decay rate, which sorts routine from periodic. The third is method, covering any surface where the wrong product or too much moisture causes damage. Those three build the positive side of the list. Most scopes fail on the first question rather than the others.
The next three build the exclusions. Reach identifies anything needing a ladder or platform. Ownership identifies surfaces covered by a base building arrangement, another contractor or the occupier's own staff. Property identifies items that will be cleaned around rather than moved. Asking all six consistently is what produces a scope that matches the building rather than a template. It also means the resulting document is shorter and more specific than a standard task list would be.
