Why Most Commercial Cleaning Happens Before You Open

The first question a facilities manager asks is what it costs. The second, which usually matters more to the outcome, is when it can happen.

Out of hours working carries a premium of roughly a quarter. Almost every commercial buyer takes it anyway, and they are right to.

What you are actually paying the premium for

Not unsociable hours, though that is part of it. You are paying for an empty site.

An empty car park can be worked in continuous passes. A car park with forty cars in it gets worked in fragments: cone off a run, wash it, wait for someone to move, come back. The same area takes half again as long and the finish is worse, because the boundary between a washed section and an unwashed one is visible until the whole thing is done and even then the joins can show.

An empty forecourt can be rinsed properly without water running into an open doorway or across the feet of someone waiting to be served.

So the quarter premium buys back most of its own cost in efficiency, and the rest of it comes back in the trade you did not lose.

The arithmetic nobody does

A pub that closes its frontage for four hours on a Saturday lunchtime to have it cleaned has lost considerably more than the difference between a weekday price and a Sunday morning one.

An office car park closed for a day means people parking on the residential streets around you, which is a conversation with neighbours you do not want to be having.

A warehouse apron closed during delivery slots means either missed collections or vehicles queuing on the road outside.

In each case the premium is the smaller number by a wide margin, which is why it is barely ever refused once it is set out this way.

What early starts do not fix

Drying time. This is the one that catches people out.

Concrete in shade in November takes hours to dry, not minutes. If you have a six o’clock wash and an eight o’clock opening, the surface will be damp when your first customers walk on it. That is fine on a car park and less fine on a smooth tiled entrance where damp equals slippery. On those surfaces the answer is either a wet vac, or scheduling the visit for a day when you open later.

Lighting is the other one. Washing in the dark is possible with site lighting or a work lamp, and I would rather not do detailed work like gum removal that way. Broad surface washing in the dark is fine. Anything that needs judging by eye wants first light.

And noise. A petrol machine at six in the morning next to residential flats is a complaint waiting to happen. Where a site is surrounded by housing, an early Sunday start is usually worse than a Tuesday one. That is a survey conversation, not something to discover on the day.

How I plan it

Tell me your quietest window and your noise constraints, and I will build the visit around both rather than picking the cheapest slot for me.

On most sites the answer lands in one of three places: before opening on a weekday, after closing on a weekday, or Sunday morning. For farms and industrial units it is different again, and that comes down to season and delivery pattern rather than time of day.
