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 Kentucky charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Science Hill 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.
Kentucky charges sales tax on commercial cleaning services, so every Science Hill cleaning invoice carries tax on top of the contract price - 6% state rate, no local sales tax. Covers residential AND commercial cleaning plus carpet, upholstery and window cleaning. DOR also treats power/pressure washing of real property as taxable janitorial service..
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Science Hill that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Kentucky janitors and cleaners earn a median of $15.54 an hour per federal wage data, which is the labor floor under every Science Hill cleaning quote - labor is roughly the whole cost structure in this trade.
Cleaning is labor, and labor is priced locally. What Kentucky sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Science Hill quotes than any vendor's sales pitch does.
The federal rules for cleaning contractors are thin; the expensive differences are state-level. Whether Kentucky 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 Science Hill quote. All three are below with official sources.

What Kentucky adds to a cleaning contract
| Question | Kentucky answer |
|---|---|
| Sales tax on commercial cleaning | Yes - taxable - 6% state rate, no local sales tax. Covers residential AND commercial cleaning plus carpet, upholstery and window cleaning. DOR also treats power/pressure washing of real property as taxable janitorial service. A $12,000/yr small-seller gross receipts exemption applies from 1/1/2025 (was $6,000). (KRS 139.200(2)(h); KY dor taxanswers Janitorial Services FAQ) |
| Median janitor wage (federal data) | $15.54 per hour |
| State minimum wage | $7.25 |
Kentucky is unusual in taxing cleaning at 6% for both homes and offices, and it stretches the janitorial category to cover power washing of sidewalks, siding and patios.

Why Kentucky rules move Science Hill 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 Science Hill buyer can verify before signing.
What this means in Science Hill
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
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.
Can I get out of a cleaning contract that renewed automatically?
It depends on your state and the contract. Some states regulate automatic renewal of service contracts - New York, for example, makes an auto-renewal clause unenforceable against the customer unless the contractor gave written reminder notice by certified mail 15-30 days before the deadline. Check your state's rule and the contract's own notice mechanics, and get counsel involved before assuming you are locked in.
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 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.
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.
