Commercial Janitorial Service Cost

Commercial janitorial service cost usually falls into a few common pricing ranges: about $0.05 to $0.20 per square foot for standard recurring office cleaning, or about $30 to $50 per hour for many jobs. For small offices, monthly cleaning often starts around $200 to $400, while larger facilities can run well above $2,000 per month depending on scope and frequency.

Typical pricing models

Most janitorial companies price work one of three ways: per square foot, per hour, or as a flat monthly contract. Per-square-foot pricing is common for recurring service, while hourly pricing is often used for one-time jobs, deep cleans, or irregular scope. Flat monthly pricing is useful when a building has a consistent cleaning schedule and a predictable workload.

Recurring service is usually cheaper than one-time cleaning because the job is easier to plan and complete efficiently. Deep cleaning, post-construction cleanup, and specialty sanitation work generally cost more because they require extra labor, equipment, and materials.

Cost by space size

A small commercial space of up to 1,000 square feet may cost about $200 to $400 per month, while a 20,000 to 40,000 square-foot facility may run about $1,250 to $1,650 or more. A 2,000-square-foot office often lands around $140 to $300 per cleaning, with an average near $220. Mid-sized offices commonly fall in the $400 to $800 monthly range depending on how often they are cleaned.

Here is a simple way to think about it:

  • 1,000 sq. ft. office: about $120 to $400 per month.

  • 4,000 to 5,000 sq. ft. office: about $370 to $550, depending on frequency and scope.

  • 10,000 sq. ft. or more: often $500+ per week or $2,000+ per month for regular service.

Cost by service type

Different facilities require different cleaning standards, and that changes the price. Office cleaning is often among the most affordable, while medical facilities, restaurants, and industrial sites usually cost more because they need more detailed sanitation and compliance. Specialized tasks like floor stripping, waxing, carpet extraction, and window cleaning are usually priced separately.

Common add-on rates include:

  • Window cleaning: about $2 to $8 per window or piece.

  • Floor stripping and waxing: about $0.30 to $0.53 per square foot.

  • Carpet shampooing or extraction: often around $0.19 to $0.40 per square foot.

  • Medical facility cleaning: often about $0.25 to $0.35 per square foot.

What affects the price

Facility size is the biggest cost driver, but it is not the only one. Cleaning frequency, building type, traffic level, and whether the job needs special chemicals or extra labor can all raise the price. A nightly office cleaning contract will usually cost less per visit than a one-time deep clean with the same square footage.

Location also matters because labor costs vary by market. Bathrooms, breakrooms, high-touch surfaces, and specialty flooring can increase the time required and therefore the final price. The more detailed the scope, the higher the quote usually becomes.

How businesses should budget

For budgeting, many companies use a monthly estimate based on square footage and frequency rather than just a single hourly rate. A small office may budget a few hundred dollars per month, while a larger or high-traffic facility may need several thousand dollars monthly. One-time cleaning and emergency service should be budgeted separately because they often carry premium pricing.

A practical rule is to ask for a scope-based quote that separates routine service from optional extras. That makes it easier to compare bids and avoid surprise charges for things like window washing, carpet cleaning, or floor care.
