What does warehouse cleaning cost?
Warehouse and industrial janitorial runs roughly $0.03–0.12 per square foot per month in Northern New Jersey at weekly service, and floor care — the auto-scrubbing pass itself — is quoted separately at $0.02–0.07 per square foot per session. They are two different products, and quoting one blended rate for both is how these bids get won or lost by accident.
Warehouse is the cheapest commercial space to clean per square foot and one of the largest contracts by total value, which is why the two figures above look so different from each other. Most confusion about warehouse pricing comes from quoting one number when the work is really two products.

The two products inside one quote
A warehouse contract is usually basic janitorial plus floor care, and they are priced on different bases. Basic janitorial covers restrooms, break rooms, offices and trash across the whole building footprint, and is quoted per square foot per month. Floor care is the auto-scrubbing pass over the open floor, quoted per square foot per session.
Quoting a single blended rate for “warehouse cleaning” is how bids get lost, or won by accident. A 100,000 sq ft distribution centre wanting nightly restrooms and a weekly scrub is buying two schedules, and a contractor who prices it as one is guessing at which.
| Scope | Rate | Basis |
|---|---|---|
| Janitorial, New Jersey | $0.03–0.12 | per sq ft / month |
| Janitorial, national | $0.08–0.15 | per sq ft, routine |
| Deep clean | $0.15–0.25 | per sq ft |
| Auto-scrubbing concrete | $0.02–0.07 | per sq ft / session |
| Standard industrial labour | $30–50 | per worker / hour |
| Hazmat, confined space | $50–75+ | per worker / hour |
Why it is cheap per square foot and not cheap per contract
Production rate. ISSA 612 puts warehouse and industrial at 5,000–7,000 sq ft per cleaner-hour against 1,800–2,500 for a medical facility, and a ride-on auto-scrubber lifts that far higher again on open floor. The same low rate over four times the area is a different business.
That is also why total contract value is high. A 100,000 sq ft unit at the middle of the range is around $6,000 a month — several times what a dental practice pays — while costing less per square foot than any other commercial type.
What actually moves the number
Racking density and obstruction, more than floor area. Two 100,000 sq ft units can differ twofold: open floor scrubs fast, and aisles between full racking do not. Anyone quoting industrial floor care from a square footage alone is quoting a building they have not seen.
Shift access. Work that has to happen around a running operation, or inside a narrow window between shifts, costs more than a building handed over empty for the night.
Compliance. OSHA training, PPE documentation and site-specific safety credentials add 25–50% to regulated industrial work. A distribution centre is not a food plant, and should not be priced as one.
Equipment. Ride-on auto-scrubbers, industrial sweepers, HEPA-filtered vacuums, pressure washers and aerial lifts are the baseline kit. A ride-on scrubber alone is $15,000–40,000, which a contractor either owns and amortises or hires and bills.
Questions people actually ask.
Is warehouse cleaning cheaper than office cleaning?
Per square foot, considerably — $0.03–0.12 a month against $0.10–0.18 for offices in the same market. Per contract it is usually far more, because warehouses are ten to twenty times the floor area.
How often should a warehouse floor be scrubbed?
Most contracts run floor care weekly or twice weekly and restrooms and break areas nightly. Scrubbing 100,000 sq ft every night is rare and is almost never what a quote assumes, so check which schedule a per-month figure is built on.
Why do warehouse quotes vary so much for the same size building?
Racking, obstruction and shift access. Those three change the cleanable area and the pace far more than total square footage does, which is why a credible industrial quote follows a walkthrough rather than a phone call.
Price a workplace
Three answers and a real figure, before anyone visits. Industrial floor care is the one type we quote only after walking it, for the reasons above.
