Commercial cleaning cost guide
The short answer: there is no single defensible monthly price based on square footage alone. CORE evaluates the building and service requirement together, using a reference model informed by actual commercial cleaning relationships sustained for approximately five years or longer. That operating history provides practical evidence of a durable balance between cost and service confidence.
Commercial cleaning cost is not a single number. It is the result of measurable building characteristics — cleanable square footage, service frequency, restrooms, kitchens, flooring, layout, activity, and scope of work — combined into a required level of labor.
This guide explains what actually moves the price, why office cleaning cost per square foot is an unreliable shortcut, and how to compare janitorial proposals on value rather than price alone.
Cleanable area is the starting point for any commercial cleaning cost estimate. Cost typically does not rise in direct proportion to size, because larger buildings gain routing and staffing efficiencies. This is why a simple flat rate per square foot tends to overstate cost for large buildings and understate it for small ones.
Frequency is usually the largest single lever on monthly cost. Five-day service costs more per month than weekly service, but less-frequent service often requires more work per visit because soil, waste, and use accumulate between cleanings.
Restrooms require more labor per square foot than general office space because of sanitation standards, touchpoint disinfection, fixture work, and consumable replenishment.
Food and beverage areas add waste volume, spills, surface sanitation, and high-touch cleaning that general office areas do not require.
Carpet and hard flooring require different routine care and different periodic maintenance. The flooring mix affects both nightly labor and long-term appearance retention.
Floor count, travel paths, elevator access, and supply staging all affect productivity. Two buildings of identical square footage can require meaningfully different labor hours.
Occupancy patterns, foot traffic, and public access change how quickly a space soils and how much attention it needs between visits.
What is included — trash, restrooms, floors, glass, disinfection, periodic work, supplies — determines the labor and materials behind the price.
A per-square-foot rate assumes every square foot requires the same work. In practice, a restroom, a break room, an open carpeted office, and a hard-floor lobby each require different labor. A 10,000 square foot medical suite and a 10,000 square foot warehouse office do not carry the same cleaning requirement, and a five-night schedule does not cost five times a one-night schedule.
Cost per square foot is useful as a result to review after the fact — not as the method used to price a building.
Normalize frequency. Compare proposals at the same number of visits per week, and look at average cost per cleaning as well as monthly price.
Confirm scope. Restrooms, floors, glass, disinfection, periodic work, and supplies should be explicitly listed, not assumed.
Ask about staffing and supervision. Labor hours on site and who inspects the work explain most price differences between proposals.
Weigh service experience. Reliability, responsiveness, and issue resolution determine whether a lower price is a saving or a risk.
Benchmark before you negotiate. A reference range built from your building's characteristics gives you a defensible starting position.

Monthly commercial cleaning cost depends primarily on cleanable square footage and service frequency, then on restrooms, kitchens, flooring, layout, activity, and scope. Rather than quoting a single national figure, CleanTech Systems' calculator builds a preliminary monthly range from your building's actual profile.
Cost per square foot is an output, not an input. It falls as buildings get larger and rises with restroom density, food areas, activity, and frequency. Using a single per-square-foot rate across different buildings is the most common source of mispriced janitorial contracts.
A 5,000 square foot office cleaned five nights per week sits in a different range than the same office cleaned twice per week. Enter the building's size, restroom count, flooring, and frequency into the calculator to see a preliminary monthly range and a per-visit figure for each frequency.
It depends on occupancy, appearance expectations, sanitation requirements, and tenant or client experience. Comparing frequencies side by side — monthly investment and average cost per cleaning — usually makes the tradeoff clear.
Compare your current monthly investment against a benchmark built from your building's characteristics, then weigh that against your actual service experience. A price below benchmark is not a good deal if service is unreliable, and a price above benchmark can be justified by scope or performance.
Quotes vary because scope, frequency, staffing, supervision, insurance, supplies, and quality oversight vary. Two proposals for the same building can describe very different levels of service, so comparing price alone is misleading.
