Why New Hampshire rules move Somersworth 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 Somersworth buyer can verify before signing.
What this means in Somersworth
'Bonded' sounds like protection and functions like credit: the bond pays only after an employee is criminally convicted, and the cleaning company repays the surety afterward. If theft protection is what a Somersworth buyer actually wants, the thing to verify is the contractor's own crime coverage and hiring screening, not the word 'bonded' on a flyer.

Common questions
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.
Are commercial cleaning companies licensed?
In most states there is no cleaning-specific license to check, which surprises buyers who expect a board to verify. A few states do license or register cleaning contractors, and many cities require a general business license. Where there is no license, verification falls to insurance certificates, references and written scope - not to a registry.
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.
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 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.
