The floor is the largest cost and the first thing to inspect
A provider should walk the floor rather than viewing it from the dock. They are looking at the sealant condition, the pattern of soiling, where tyre marks concentrate, whether any area is permanently obstructed, and how much of the surface a machine can genuinely reach. Those observations determine the equipment, the hours and the realistic frequency, which together make up most of the figure they will quote.
Watch whether they ask about the floor's history. Whether it has been scrubbed before, what product was used, whether any coating has been applied, and whether there are areas subject to spills. A provider gathering that information is planning a programme. One who glances at the floor and moves on will be pricing from area alone, which is the least reliable basis available for a surface of that size.
