The metro holds 9,434,123 people across 13 counties in Illinois and Indiana. Population has held steady, and most work happens in existing buildings with real wear. Health care leads employment, and the region counts 100 hospitals, with medical office buildings in nearly every submarket. Manufacturing still employs hundreds of thousands, concentrated in Will, Lake, and DuPage counties, where floor care and break-room sanitation drive the work. Salt and slush tracked into lobbies each winter call for entry matting, extra mopping, and floor refinishing on a seasonal plan. Office corridors in Schaumburg, Naperville, and Downers Grove also run on different hours than downtown. Janitors earn a median of $17.99 an hour. Request a free facility assessment.

What this means when you scope a building

  • Plan winter floor care from November through March. Salt residue damages hard floors and carpet fast. Budget for extra entry mopping and a spring scrub-and-recoat.
  • Downtown towers often need porters during business hours, while suburban offices in Schaumburg or Naperville can usually be cleaned entirely after close.
  • With 13 counties across two states, sites in Lake County, Indiana and Kane County, Illinois run as separate routes from Loop buildings.
  • Manufacturing employs 370,871 people here. Plants and warehouses need scrubber work on production floors, with offices and locker rooms on their own schedule.

Which parts of the Chicago area do you serve?

We take assessment requests throughout the metro, including Cook, DuPage, Lake, Will, Kane, and McHenry counties in Illinois and Lake and Porter counties in Indiana.

What drives commercial cleaning prices in Chicago?

Labor is the biggest input, and BLS reports a median janitor wage of $17.99 an hour in the metro. Your quote is built from the walkthrough: square footage, floor types, traffic, restroom counts, and how often each area is serviced. Seasonal floor care for winter is priced as its own line.

How do you handle winter salt and slush in Chicago buildings?

We add entrance matting checks, more frequent lobby mopping during storms, and neutral cleaners that lift salt film from hard floors. We schedule a scrub and recoat in spring, once the salt season ends.
