Why minimum attendance length matters
No contractor will roster a very short visit at distance, because the travel cannot be justified against the productive time. That produces a floor under the price which has nothing to do with your building's size. A small Camden suite needing forty minutes of work may still be quoted for a longer minimum attendance, and understanding that early prevents a fruitless search for a cheaper version of the same thing.
The useful response is to use the minimum rather than fight it. If the attendance has to be ninety minutes, decide what else is worth doing in the remaining time: internal glass on a rotation, detailed kitchen work, storeroom tidying or periodic tasks brought forward. That converts an awkward pricing floor into genuine value, and it gives the schedule content that would otherwise be squeezed out entirely.
