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 Montana charges in sales tax, whether it licenses cleaning companies at all, and what its wage floor does to Darby 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.
Montana does not charge sales tax on commercial cleaning services, so a Darby cleaning quote is the whole price - Montana has no general statewide sales tax, so commercial cleaning invoices carry no sales tax. Only selective/local-option taxes (e.g. resort area and lodging taxes) exist, none of which target janitorial services..
Montana does not license commercial cleaning companies, so there is no state registry for Darby buyers to check - verification falls to insurance certificates, written scope and references, which is exactly why those three matter here.
Montana janitors and cleaners earn a median of $17.84 an hour per federal wage data, which is the labor floor under every Darby 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 Montana 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 Darby 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 Montana does or does not require - and what that means for verifying a Darby contractor - is set out below, with the state's own source next to it.

What Montana adds to a cleaning contract
| Question | Montana answer |
|---|---|
| Sales tax on commercial cleaning | No - not taxable - Montana has no general statewide sales tax, so commercial cleaning invoices carry no sales tax. Only selective/local-option taxes (e.g. resort area and lodging taxes) exist, none of which target janitorial services. |
| Licence or registration required | No state licence for cleaning companies - No statewide general business license and no cleaning/janitorial-specific state license. MT Dept of Commerce: local city and county offices provide all business licensing; the state issues professional licenses. Register the entity with the MT Secretary of State. |
| Median janitor wage (federal data) | $17.84 per hour |
| State minimum wage | $10.85 |
Montana charges no state sales tax on cleaning contracts, so the whole invoice is labor and materials - but its minimum wage is re-indexed to inflation every January, so bids drift upward yearly.

Why Montana rules move Darby 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 Darby buyer can verify before signing.
What this means in Darby
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
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.
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.
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.
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.
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.
