Updated September 2026 by Kunz Janitorial, Inc., Phoenix, Arizona. Commercial cleaning since 1971.
How commercial cleaning is priced
Most Phoenix janitorial companies price one of three ways: per square foot per visit, per hour of labor, or as a flat monthly fee for a defined scope. The flat monthly fee is the most common for recurring service because it is easiest to budget. Underneath it, the company is still estimating labor hours from square footage, task list, and frequency.
Typical ranges (industry, not Kunz rates)
| Facility type | Typical range, per sq ft per visit | Notes |
|---|---|---|
| General office, 3 to 5 nights a week | $0.08 to $0.18 | Restrooms, trash, floors, breakroom, dusting |
| Professional or class-A office, nightly | $0.12 to $0.25 | Higher finish, glass, conference rooms |
| Medical or dental office | $0.15 to $0.35 | Disinfection protocols, exam rooms, waiting areas |
| School or church | $0.10 to $0.25 | High-touch surfaces, restrooms, gyms, kitchens |
| Retail or showroom | $0.10 to $0.22 | Entry glass, floors, customer restrooms |
| Day porter (hourly) | $25 to $45 per hour | On-site daytime staff, usually 4 to 8 hours a day |
These are published ranges for the commercial cleaning industry in metro markets like Phoenix and are shown so a buyer can sanity-check a quote. They are not Kunz Janitorial rates. Small buildings often carry a monthly minimum because the drive, setup, and supplies cost the same whether the space is 1,500 or 4,000 square feet.
What pushes the price up
- More frequent service (nightly vs. weekly) lowers the per-visit rate but raises the monthly total
- Medical, dental, and lab space with disinfection protocols
- High restroom count relative to square footage
- Hard floors that need regular machine scrubbing or burnishing
- Daytime cleaning around occupied space, which is slower
- Consumables included (paper, soap, liners) versus supplied by the building
What brings the price down
- Consistent access and alarm procedures so crews are not waiting
- A realistic scope: not every area needs nightly attention
- Longer commitments, since crews stay assigned and learn the building
- Bundling day porter and nightly service under one vendor
How Kunz quotes
Kunz walks the building first, writes a scope by area and frequency, and quotes against that scope. The quote is transparent: no hidden fees or surprise charges, and the scope is the document both sides work from. Kunz has priced commercial cleaning in Phoenix since 1971 and is locally owned and owner-operated.
