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 Connecticut charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Norwich 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.
Connecticut charges sales tax on commercial cleaning services, so every Norwich cleaning invoice carries tax on top of the contract price - Janitorial services are expressly enumerated as taxable services, at Connecticut's 6.35% general sales and use tax rate, and apply to both residential and commercial customers. Connecticut has no local sales tax add-ons..
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Norwich that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Connecticut janitors and cleaners earn a median of $18.25 an hour per federal wage data, which is the labor floor under every Norwich 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 Connecticut does or does not require - and what that means for verifying a Norwich contractor - is set out below, with the state's own source next to it.
Cleaning is labor, and labor is priced locally. What Connecticut sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Norwich quotes than any vendor's sales pitch does.

What Connecticut adds to a cleaning contract
| Question | Connecticut answer |
|---|---|
| Sales tax on commercial cleaning | Yes - taxable - Janitorial services are expressly enumerated as taxable services, at Connecticut's 6.35% general sales and use tax rate, and apply to both residential and commercial customers. Connecticut has no local sales tax add-ons. (Conn. Gen. Stat. sec. 12-407) |
| Median janitor wage (federal data) | $18.25 per hour |
| State minimum wage | $16.94 |
Connecticut charges 6.35% sales tax on the janitorial invoice itself, so a commercial cleaning contract there costs measurably more than the same scope of work across the border in Massachusetts.

Why Connecticut rules move Norwich 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 Norwich buyer can verify before signing.
What this means in Norwich
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 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.
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.
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.
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.
Am I liable for the cleaning company's employees?
Usually not, but the boundary matters. Joint-employer liability, where it exists, is joint and several - meaning each employer can be responsible for the full amount of wages owed. Federal labor regulators have proposed guidance indicating that giving routine instructions, monitoring quality, or even asking for a worker to be replaced does not by itself create that status; directly scheduling workers, keeping their time records and controlling hiring and firing points the other way. This is a fact-specific area - ask counsel about your own arrangement.
