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 Walsh 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 Walsh 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); general labor and services such as janitorial work are not among them..
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Walsh 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 Walsh cleaning quote - labor is roughly the whole cost structure in this trade.
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 Walsh quote. All three are below with official sources.
Most states do not license commercial cleaning companies, which surprises buyers who assume there is a board to check. What Colorado does or does not require - and what that means for verifying a Walsh contractor - is set out below, with the state's own source next to it.

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 Walsh 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 Walsh buyer can verify before signing.
What this means in Walsh
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
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.
Do I still need pandemic-level disinfection?
Federal guidance now tells buyers to determine whether disinfecting is necessary at all before purchasing disinfectants, and notes that disinfectants - which EPA regulates as pesticides - are more hazardous than plain cleaners. Routine whole-building fogging sold as standard is worth questioning; targeted disinfection of high-touch surfaces where circumstances warrant it is a different conversation.
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 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.
