Janitorial services Phoenix AZ: desert dust, a vast low-rise footprint and summers that move the work at night

What the companies publish

Specifying for dust and distance

1. Ask where the crew is based before you ask the rate. Travel across this metro is a real cost and it lands somewhere. A contractor with a crew near your building will usually beat a cheaper hourly rate travelling an hour each way, and they will be able to respond when something happens. It is rarely on a tender form and it is the first thing worth asking.
2. Treat dust as a standing line, not a nuisance. Fine dust arrives continuously on shoes, on vehicles and through every opening, and it settles on glass, horizontal surfaces and high level. Barrier matting does more here than in almost any other climate, and high dusting comes round faster than a national interval would suggest.
3. Say what happens in summer. Extreme summer heat moves outdoor and semi-outdoor work to the night and changes how long a crew can sustain it. Where any part of your scope is outside conditioned space, the season belongs in the schedule rather than in an assumption.
4. Split low-rise office from industrial and warehouse. Phoenix holds a very large distribution and light-industrial base alongside its offices. Those are machine work and crew hours respectively, not per-square-foot jobs, and a blended rate across both hides where the money goes.

Common questions

Why does crew base matter so much?

Because the metro is large and flat. Two contractors quoting the same specification from different sides of it are quoting different amounts of driving.

Does the dust shorten intervals?

On entrances, glass and high level it does, measurably enough that buildings here schedule high dusting more often than a national specification would.

Do the published figures help?

As a band for conventional office space. Distribution and light-industrial space is not what any of them measured.
