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 Missouri charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Granby 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 Granby 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 Granby that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Missouri janitors and cleaners earn a median of $17.26 an hour per federal wage data, which is the labor floor under every Granby cleaning quote - labor is roughly the whole cost structure in this trade.
Cleaning is labor, and labor is priced locally. What Missouri sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Granby quotes than any vendor's sales pitch does.
The federal rules for cleaning contractors are thin; the expensive differences are state-level. Whether Missouri charges sales tax on cleaning services, whether it licenses cleaning contractors at all, and what its wage floor does to labor cost are the three that show up in a Granby quote. All three are below with official sources.
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.

What Missouri adds to a cleaning contract
| Question | Missouri answer |
|---|---|
| Median janitor wage (federal data) | $17.26 per hour |
| State minimum wage | $15.00 |
Missouri's voter-approved wage schedule pushed the state floor to $15.00 by 2026, more than double neighboring Mississippi's and Louisiana's federal $7.25, making janitorial labor cost swing sharply across state lines in the same region.

Why Missouri rules move Granby 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 Granby buyer can verify before signing.
What this means in Granby
'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 Granby 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 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.
Are commercial cleaning companies licensed?
In most states there is no cleaning-specific license to check, which surprises buyers who expect a board to verify. A few states do license or register cleaning contractors, and many cities require a general business license. Where there is no license, verification falls to insurance certificates, references and written scope - not to a registry.
How long are commercial cleaning contracts?
Twelve months is the private-sector norm, and automatic renewal is close to universal. The common evergreen wording continues the agreement for successive twelve-month periods without an 'unless you give notice' qualifier, so the exit depends entirely on a separate notice clause - commonly 30 days before the term ends. Calendar that date the day you sign.
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.
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.
