If you are comparing bids for commercial cleaning cost per square foot in Chicago suburbs, you have probably noticed that no two quotes look the same. One company quotes a flat monthly rate, another prices by square footage, and a third asks for a walkthrough before giving any number at all. Here is how pricing actually works across Schaumburg, Des Plaines, Hanover Park, Glendale Heights, Bloomingdale, and the rest of Cook County — and what to ask before you sign.
Commercial Cleaning Cost Per Square Foot in Chicago: How Quotes Work
Most janitorial companies in the suburbs quote per square foot per cleaning, then multiply by your frequency to get a monthly rate. The per-square-foot number is not a published list price — it is built from your building. Two 5,000-square-foot offices can land on very different numbers, which is why any honest company will want to walk your space before quoting.
That walkthrough is the single most important step. It is also the fastest way to spot a quote that is too good to be true: a bid built without seeing your restrooms, breakroom, floors, and trash load is a bid that will either miss work or come back with add-ons later.
What Moves Your Quote Up or Down
- Frequency. Nightly service costs more per month than weekly, but the per-visit rate drops. Weekly or bi-weekly routes are the sweet spot for most small and mid-size offices.
- Building type. Offices are the baseline. Medical facilities, restaurants, and buildings with heavy public traffic run higher because of disinfection standards, grease, and extra restroom traffic.
- Restrooms and breakrooms. These are the labor-heavy rooms. More fixtures and more traffic mean more time on every visit.
- Floor types. Carpet, VCT, tile, and polished concrete each clean differently. VCT that needs periodic strip and wax is a separate line from routine service — ask whether the quote includes it or not.
- Scope extras. Trash handling, window interiors, dusting height, lobby detailing, and consumable restocking can be in or out. The cheapest bid often just leaves the most out.
- Labor market. Cook County rates reflect real staffing costs. A bid far below the pack usually means corner-cutting — rushed crews, no supervision, or constant turnover.
How to Compare Bids Apples to Apples
Ask every company for the same four things: the full scope in writing (every room, every task, every frequency), whether the quote came from an on-site walkthrough, who supervises the crew and how problems get reported, and what is not included that might be billed later. The company that answers those questions clearly — with a real person you can reach — is worth more than the company that shaves a few dollars off the monthly number.
