How much does commercial cleaning cost?

A cleaning price is a labor estimate. It reflects how many hours a crew needs in your building each week, what those hours cover, and which supplies come with them. When the inputs are wrong, even a low bid gets expensive once the restrooms start slipping.

This guide covers what drives the cost, what published industry ranges say, and how a walkthrough produces a figure you can budget against. If you are pricing an office, see office cleaning services for the typical room list. For the nightly task list, see janitorial services.

What drives the price

Every estimate starts with square footage, but the final number usually depends on the inputs below.

• Square footage, and what it includes. Usable, rentable, and gross area are different numbers. A 20,000-square-foot figure that includes a warehouse bay, a garage, or stairwells describes a smaller office. Price the cleanable area.
• Frequency. Five nights a week costs more than three, and each room can have its own frequency. Restrooms and entries often need every visit. Private offices may need two.
• Restrooms. Fixture count matters more than restroom count. Restrooms take the most labor in most buildings and are the first place occupants notice a problem.
• Floor types. Carpet, vinyl tile, sealed concrete, and stone each need different daily care and different periodic work. Strip and refinish, scrub and recoat, burnishing, and carpet extraction are scheduled projects. See floor care for how we plan them.
• Porter hours. A public lobby, a clinic waiting room, or heavy daytime traffic may call for a porter during open hours, priced by the hour as its own line. Our day porter vs night janitor guide explains when it pays off.
• Specialty areas. Exam rooms, cafeterias, break rooms with appliances, fitness rooms, and production-adjacent spaces each add tasks.
• Supplies. A price that includes paper, soap, liners, and chemicals can't be compared with one that assumes you buy them.
• Access and timing. Badge rules, escorts, short alarm windows, and early opening times shape when and how the crew works.
• Multiple sites. Travel and supervision between addresses add time. A portfolio price should still show each site.

Published industry price ranges

Other companies publish typical ranges, which help with a rough budget check. These are third-party industry figures. They are not our rates, and they won't tell you what your building costs.

What the ranges tell you

Apply the standard office band to a 20,000-square-foot office. The low end is about $1,400 a month and the high end about $5,000. The same building can land anywhere in that spread depending on frequency, restrooms, floors, and the task list. Use the range to sanity-check a bid. It is too wide to set a budget.

Hourly rates need the same care. An hourly quote and a monthly fee only compare once both name the tasks, the frequencies, and the hours on site.

Why a walkthrough gives you a real number

A walkthrough replaces averages with your building. During the visit we count restroom fixtures, check floor types and condition, note public areas and break rooms, review access rules, and ask when the building is busiest. The result is a task list with a frequency for each area, and the price comes from that list.

The proposal you receive breaks out:

1. Each area and its tasks.
2. How often each task happens.
3. Crew hours and any porter hours.
4. Periodic floor care, with dates.
5. Who supplies consumables and equipment.
6. The cost of each line.

With each line visible, you can fit the program to a budget. Drop a floor to three nights, move carpet extraction to twice a year, or add lobby porter hours, and you can see what changes.

How to compare bids fairly

Line up every proposal against the same task list. Check that each bid covers the same areas, frequencies, periodic floor work, and supplies. A bid that is 20 percent lower because it drops weekly restroom detailing or the floor calendar is pricing less work.

Look at how quality is managed, too. Ask who your account manager will be, how supervisors inspect the work, and how a missed task gets handled. Our guide on how to hire a commercial cleaning company covers the questions to ask, and what janitorial services include explains how to read a task list.
