What the state adds to the price, and what it lets you verify
Federal rules for cleaning contractors are thin; the expensive differences are state-level. What Illinois charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Northlake labor cost are below with official sources.
Two free marketplace paths: one request brings back multiple vetted cleaning contractors who know they are competing for the account.
Illinois does not charge sales tax on commercial cleaning services, so a Northlake cleaning quote is the whole price. Illinois does not tax sales of service, so a charge for janitorial or building-cleaning labor is not subject to Illinois sales tax; residential and commercial customers are treated the same.
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Northlake that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Illinois janitors and cleaners earn a median of $18.18 an hour per federal wage data, which is the labor floor under every Northlake cleaning quote - labor is roughly the whole cost structure in this trade.
Most states do not license commercial cleaning companies, which surprises buyers who assume there is a board to check. What Illinois does or does not require - and what that means for verifying a Northlake contractor - is set out below, with the state's own source next to it.
Cleaning is labor, and labor is priced locally. What Illinois sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Northlake quotes than any vendor's sales pitch does.

What Illinois adds to a cleaning contract
| Question | Illinois answer |
|---|---|
| Sales tax on commercial cleaning | No - not taxable - Illinois does not tax sales of service, so a charge for janitorial or building-cleaning labor is not subject to Illinois sales tax; residential and commercial customers are treated the same. Illinois does impose the Service Occupation Tax on items of tangible personal property transferred as an incident to a sale of service, so property handed over to the customer as part of the job can still be taxed. (86 Ill. Adm. Code Part 140 (Service Occupation Tax)) |
| Median janitor wage (federal data) | $18.18 per hour |
| State minimum wage | $15.00 |

Why Illinois rules move Northlake quotes
Two of the three state variables land directly on your invoice. Sales tax, where a state charges it on cleaning services, is added to every monthly bill - on a mid-size contract that is real money over a year. The wage floor sets the labor cost every bid is built on, which is why identical buildings in different states get materially different quotes. Licensing is the third and it works differently: it does not change the price, it changes what a Northlake buyer can verify before signing.
What this means in Northlake
The most expensive cleaning contract is the one that renews itself. The common evergreen clause continues the agreement for successive twelve-month periods with no 'unless you give notice' language attached - so a Northlake building that misses the 30-day window has bought another full year at whatever the new rate is.

Common questions
What does 'bonded and insured' actually mean?
They are two different things and only one behaves like protection. Insurance - general liability, typically $1 million per occurrence, plus workers' compensation - responds to covered claims. A janitorial surety bond covers employee theft but pays only after the employee is criminally convicted, and the cleaning company must reimburse the surety afterward. It is closer to a credit guarantee than to insurance.
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.
What does floor stripping and waxing cost?
Strip and refinish runs about $0.30-$0.80 per square foot in 2026 pricing, and scrub-and-recoat - the lighter maintenance version - about $0.20-$0.40. Most vendors apply a minimum service fee of roughly $250-$500, which makes small jobs disproportionately expensive per square foot.
Is a certificate of insurance enough proof?
It is a starting point, not proof. The standard certificate states in its own header that it confers no rights upon the certificate holder - it is a snapshot of what was in force the day it was issued, with limits that may already be partly consumed by other claims. Ask the broker to send it directly, have your entity named as additional insured, and re-request it at renewal.
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.
