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 Colorado charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Blue River 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.
Colorado does not charge sales tax on commercial cleaning services, so a Blue River cleaning quote is the whole price. Colorado taxes retail sales of tangible personal property plus a short list of enumerated services (telecom, lodging, prepared food, certain utilities).
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Blue River that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Colorado janitors and cleaners earn a median of $18.56 an hour per federal wage data, which is the labor floor under every Blue River cleaning quote - labor is roughly the whole cost structure in this trade.
Cleaning is labor, and labor is priced locally. What Colorado sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Blue River quotes than any vendor's sales pitch does.
The federal rules for cleaning contractors are thin; the expensive differences are state-level. Whether Colorado 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 Blue River quote. All three are below with official sources.

What Colorado adds to a cleaning contract
| Question | Colorado answer |
|---|---|
| Sales tax on commercial cleaning | No - not taxable - Colorado taxes retail sales of tangible personal property plus a short list of enumerated services (telecom, lodging, prepared food, certain utilities); general labor and services such as janitorial work are not among them. Separately stated labor charges are not taxed. |
| Median janitor wage (federal data) | $18.56 per hour |
| State minimum wage | $15.16 |
Colorado neither licenses cleaners at the state level nor taxes janitorial services, so the main state-driven cost variable is its annually indexed minimum wage plus higher Denver-area local floors.

Why Colorado rules move Blue River 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 Blue River buyer can verify before signing.
What this means in Blue River
'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 Blue River 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
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 '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.
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.
How much does office cleaning cost per month?
For a small office cleaned three times a week, published ranges start around $100-$250 a month at the smallest sizes and run to $250-$800 for a few thousand square feet, with larger spaces at $350-$1200 and up. Restroom count, floor type and whether consumables are included move these more than most buyers expect.
