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 Elsah 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.
Whether a cleaning invoice carries sales tax depends entirely on the state, and a minority of states do tax cleaning services - in those states it adds several percent to every monthly bill a Elsah business pays, which is why the contract price is not the whole price.
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Elsah 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 Elsah 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 Elsah 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 Elsah quotes than any vendor's sales pitch does.
Put a compliance check out to competing bids before comparing prices
Two free marketplace paths: one request brings back multiple vetted cleaning contractors who know they are competing for the account. Competing bids on identical scope are the only reliable way to learn what your building actually prices at.

Why Illinois rules move Elsah 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 Elsah buyer can verify before signing.
What this means in Elsah
'Bonded' sounds like protection and functions like credit: the bond pays only after an employee is criminally convicted, and the cleaning company repays the surety afterward. If theft protection is what a Elsah buyer actually wants, the thing to verify is the contractor's own crime coverage and hiring screening, not the word 'bonded' on a flyer.

Common questions
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.
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.
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.
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.
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.
