The questions that separate contractors - all askable before you sign
Cleaning companies are easy to compare on price and hard to compare on whether the work will still be done properly in month nine. These are the questions that produce different answers from different bidders in Joliet.
Two free marketplace paths: one request brings back multiple vetted cleaning contractors who know they are competing for the account.
About 37.5% of America's janitors work for contract cleaning companies rather than for the buildings they clean, so the Joliet market is a genuine contractor market - competing bids on identical scope are both realistic and the only way to price a building.
Montana does not license commercial cleaning companies, so there is no state registry for Joliet buyers to check - verification falls to insurance certificates, written scope and references, which is exactly why those three matter here.
Joliet plus 3 surrounding communities within 40 km hold about 12,523 people, enough commercial density that several cleaning contractors will bid the same building - which is the competition a single quote request is meant to create.
The cleaning industry has almost no licensing to check, which means verification falls to the buyer. For a Joliet building that means insurance certificates from the broker, a named account manager, a written scope with frequencies, and references from buildings your size.
Turnover is this industry's defining problem, and it lands on your floor as inconsistent work. Ask any Joliet bidder how they staff the account, who supervises, and what happens when the regular cleaner is out - the answer predicts month six better than the price does.

Four ways to buy cleaning, compared
| Model | Who actually does the work | Fits | Watch for |
|---|---|---|---|
| National contractor | Employees, managed through a regional account team | Multi-site buyers wanting one contract and consistent reporting | Account manager turnover; local crew quality varies by branch |
| Local independent company | Its own employees, often with the owner still involved | Single-site buildings wanting a responsive relationship | Thinner cover when staff are sick; verify insurance yourself |
| Franchise unit | A franchisee who bought the territory, under a national brand | Buyers who want a brand's standards at local-company scale | Ask who employs the cleaners and who carries the insurance |
| Hiring cleaners directly | Your own employees | Buildings large enough to justify supervision and payroll overhead | You take on payroll tax, workers' comp, cover for absences and chemical training |
Verify before any signature
- Ask the broker - not the contractor - to send the certificate of insurance directly, and have your entity named as additional insured
- Confirm general liability limits of at least $1 million per occurrence and workers' compensation in force in your state
- Ask what the bond actually covers and what triggers payment (the answer should include a criminal conviction, and that tells you its real value)
- Get the scope of work in writing with frequencies per area, not a paragraph of adjectives
- Ask for two references from buildings of similar size and type in your area, and call them
- Confirm who supervises, how often they inspect, and what the remedy is when work is missed
- Confirm the initial term, the renewal mechanism, and the exact notice window - then calendar the notice date the day you sign
- Ask whether staff are employees or subcontractors, and how they are screened and trained
Walk away when you see
- A price per square foot with no stated frequency - the two numbers are meaningless apart
- 'Bonded and insured' offered as an answer instead of an actual certificate and bond type
- A certificate of insurance forwarded by the contractor rather than issued by the broker
- An evergreen renewal clause with the notice window buried in a separate paragraph
- No named supervisor or account manager, and no answer on how absences are covered
- Routine fogging or whole-building disinfection sold as standard rather than justified
- Consumables 'included' with no monthly allowance stated - the true-up arrives later
- A bid materially below the local band with no explanation of what was scoped out
What a real commercial cleaning quote contains - and what the padded version sells
A complete quote includes
- Cleanable square footage and frequency stated together, per area
- A written scope listing what is done nightly, weekly, monthly and annually
- Specialty work priced explicitly as included or billed on top
- Insurance limits stated, with the certificate coming from the broker
- The initial term, the renewal mechanism and the exact notice window
- A named supervisor and a stated inspection frequency
Red flags in a cleaning proposal
- A per-square-foot price with no frequency attached
- 'Bonded and insured' offered instead of documents
- Consumables 'included' with no monthly allowance stated
- Auto-renewal with the notice window in a separate paragraph
- Routine whole-building disinfection sold as standard
- A bid far below the local band with no explanation of what was cut
What this means in Joliet
A certificate of insurance proves someone had coverage on the day it printed. It confers no rights on you, it does not obligate the insurer to notify you if the policy lapses, and the limits shown may already be partly consumed. Ask for the certificate from the broker, name your entity as additional insured, and re-request it at renewal.

Common questions
Do I have to pay sales tax on cleaning services?
That depends entirely on your state - most states do not tax cleaning services, but a minority do, and in those states it is a real line on a real invoice: at typical rates it adds several percent to every monthly bill. This site publishes the treatment state by state with the revenue department's own source; check your state's page.
How do I compare two very different cleaning bids?
Normalize three things before you look at price: total cleanable square footage, frequency per area, and exactly which specialty services are inside the monthly fee. Most large gaps between bids disappear once those are matched - and the ones that survive are usually explained by staffing model or supervision, which is worth paying for.
How much does commercial cleaning cost per square foot?
In 2026 industry ranges, general office space runs about $0.09-$0.17 per square foot per month, medical and healthcare $0.14-$0.29, industrial $0.08-$0.20, retail $0.07-$0.15 and schools $0.07-$0.14. Those figures assume a stated frequency - a per-square-foot price without a frequency attached tells you nothing.
Does cleaning less often save money?
Less than you would think, and sometimes not at all. Soil accumulates between visits, and industry measurement puts the additional cleaning time required by infrequent service at 60-70%. The per-visit price rises as frequency falls, so halving the schedule does not halve the bill - and the building looks worse in between.
Is it cheaper to pay hourly or per square foot?
Neither is inherently cheaper; they suit different jobs. Hourly pricing runs $25-$75 per worker per hour and fits small or irregular scopes. Square-foot pricing fits predictable routine work and makes budgeting easier. The only fair comparison is to ask every bidder for the all-in monthly total on identical scope and frequency, then divide.
