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 Maryland charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Centreville 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.
Maryland taxes cleaning services only in part, and the split usually falls exactly where Centreville business buyers sit. 6% state rate, no local add-on.
Most states do not license commercial cleaning companies, which surprises buyers who assume a board exists to check - in Centreville that means insurance certificates, a written scope and real references do the verifying that a licence would elsewhere.
Maryland janitors and cleaners earn a median of $17.61 an hour per federal wage data, which is the labor floor under every Centreville 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 Maryland does or does not require - and what that means for verifying a Centreville contractor - is set out below, with the state's own source next to it.
Cleaning is labor, and labor is priced locally. What Maryland sets as its wage floor, and what janitors in the state actually earn at the median, explain more of the spread between Centreville quotes than any vendor's sales pitch does.

What Maryland adds to a cleaning contract
| Question | Maryland answer |
|---|---|
| Sales tax on commercial cleaning | Partly - depends on the work - 6% state rate, no local add-on. Applies to cleaning of a COMMERCIAL or INDUSTRIAL building, including floor, carpet, wall, window, ceiling and exterior cleaning and janitorial services. Residential cleaning is outside the definition and untaxed. (Md. Tax-General Sec. 11-101(m)(3)) |
| Median janitor wage (federal data) | $17.61 per hour |
| State minimum wage | $15.00 |
Maryland is one of the few states that taxes commercial janitorial work but not residential: cleaning a commercial or industrial building carries 6% sales tax, so a quote for an office is taxed while the identical house cleaning is not.

Why Maryland rules move Centreville 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 Centreville buyer can verify before signing.
What this means in Centreville
Cutting frequency looks like the obvious way to cut a Centreville cleaning bill, and it is the one that backfires: infrequent service raises the cleaning time a building needs by 60-70%, so the per-visit price climbs while the building gets dirtier between visits.

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.
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 floor stripping and waxing cost?
Strip and refinish runs about $0.30-$0.80 per square foot in 2026 pricing, and scrub-and-recoat - the lighter maintenance version - about $0.20-$0.40. Most vendors apply a minimum service fee of roughly $250-$500, which makes small jobs disproportionately expensive per square foot.
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.
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.
