Do not plan maintenance as if the backlog has already gone.
You may want help with everyday household cleaning but first need attention to old grease, bathroom deposits or accumulated room dust. Those tasks can make the initial workload different from a later repeat visit. Explain them before choosing the first appointment instead of hiding a larger job under routine hours.
A one-off deep clean can be discussed as the initial work, with its own priority list. It does not automatically establish future attendance or a fixed result for every mark. The cleaner needs to know the areas requiring suitable dirt removal and anything that is damaged, restricted or inaccessible.
