Quick answer: Commercial cleaning is professional cleaning for businesses, institutions and commercial buildings, such as offices, medical practices, shops and schools. Compared with home cleaning, it covers larger spaces, more foot traffic and stricter rules, and it usually runs on a written scope, a set schedule and hours outside the working day.

If you run an office or a small business, you have probably seen “commercial cleaning” on quotes and service pages without a clear explanation of what you are actually buying. Is it the same as janitorial service? Does it include floors and windows? How is it different from the cleaner who does your home?

This guide answers what is commercial cleaning in plain terms: what it covers, the main types, how it differs from residential and janitorial work, how a service is set up and what it costs. We are Lucy’s Cleaning Home, and we have cleaned homes, offices and small business spaces across Haverhill, the Merrimack Valley and southern New Hampshire for more than 16 years.

What is commercial cleaning?

Commercial cleaning is the professional cleaning of spaces used for business rather than for living. ISSA, the worldwide cleaning industry association, defines it as professional cleaning services provided to businesses, institutions and commercial buildings, and notes that it handles more complex tasks than home cleaning because of larger spaces, higher foot traffic and strict industry regulations (ISSA, What is Commercial Cleaning?).

In practice, commercial cleaning means a company cleans a workplace on a schedule, following a written list of tasks that the business agrees to in advance. The typical buildings include:

• Offices and coworking spaces
• Medical, dental and healthcare facilities
• Retail stores and showrooms
• Schools and childcare centers
• Industrial sites and warehouses

It is a large industry. ISSA, citing U.S. Bureau of Labor Statistics data from 2023, reports more than 3 million janitors and building cleaners working in more than 1.2 million businesses, with industry revenue forecast to exceed $108 billion in 2025.

What does commercial cleaning include?

Commercial cleaning includes routine cleaning, floor care, specialty cleaning and disinfection. Here is a practical commercial cleaning list of services, grouped the way most companies quote them:

1. Routine cleaning. Trash and recycling, dusting, wiping desks and surfaces, cleaning break rooms and kitchens, and vacuuming and mopping.
2. Restroom care. Cleaning and disinfecting fixtures, restocking soap, towels and paper, and mopping floors.
3. High-touch disinfection. Door handles, light switches, elevator buttons, shared phones and keyboards.
4. Floor care. Periodic carpet cleaning and hard-floor scrubbing or refinishing, usually quoted separately.
5. Specialty cleaning. Window washing and post-construction cleanup, often handled by specialist crews.
6. Deep cleaning. A periodic reset of the whole space, beyond the routine list.

Not every company offers every item. The written scope, often a checklist, is what tells you which of these your contract covers. Our commercial cleaning checklist by zone shows what that list looks like for an office, task by task.

Commercial cleaning vs residential cleaning

The difference between commercial and residential cleaning is scale, rules and scheduling. Residential cleaning follows one household’s rooms and routine. Commercial cleaning follows a business: many users, shared spaces, and standards that come from the workplace, not from a family.

Can the same company do both? Yes. Many local companies clean homes and small offices, and office and commercial cleaning often sits alongside residential work in a smaller business. What changes is the setup: a business needs a written scope, a sign-off after each visit and access outside working hours. For the home side of the comparison, our guide to deep cleaning vs regular cleaning explains how residential cleaning is usually split.

Commercial cleaning vs janitorial services

Janitorial service is one part of commercial cleaning, not a different thing. ISSA lists routine janitorial services as one category inside commercial cleaning, alongside floor care, specialty cleaning and disinfection.

In everyday use, people mean slightly different jobs by each word:

• Janitorial usually means the routine daily or nightly work: trash, restrooms, surfaces and floors, often with some on-site maintenance tasks.
• Commercial cleaning is the wider umbrella, which also covers periodic deep cleaning, floor care and specialty jobs.

When you compare offers for commercial cleaning and janitorial work, look past the label and read the scope. Two quotes with different names can describe the same visit, and two with the same name can be very different.

What are the main types of commercial cleaning?

The main types of commercial cleaning follow the type of building, because each one has different traffic, surfaces and rules.

• Office cleaning. Workstations, restrooms, break rooms, conference rooms and floors, usually after hours.
• Medical and dental cleaning. Infection-control protocols set by the practice and its regulators, with stricter disinfection.
• Retail cleaning. Floors, glass, fitting rooms and customer restrooms, often before opening.
• School and childcare cleaning. Classrooms, cafeterias and restrooms, with extra attention to surfaces children touch.
• Industrial cleaning. Warehouses and production areas, often with specialized equipment.

For most small businesses, office cleaning is the core of the contract, and restrooms are its most demanding zone. Our restroom cleaning checklist for offices breaks down that part on its own.

How often do businesses need commercial cleaning?

Most offices need restrooms, trash and high-touch surfaces cleaned daily, with detailed dusting and floor work weekly and a deeper reset monthly or quarterly. A small office with few people can often work with two or three visits a week, as long as the restroom and break room are covered each time.

The right frequency depends on headcount, visitors and the type of work. A dental practice, a retail floor and a three-person accounting office will not need the same schedule, even at the same size.

How does a commercial cleaning service work?

A commercial cleaning service works from a written scope and a fixed schedule. The usual steps are:

1. Walk-through. The company visits the space and notes every zone, floor type and special surface.
2. Scope and checklist. Each task is marked daily, weekly, monthly or quarterly.
3. Schedule and access. Visits are set for times that do not disrupt the business, often evenings.
4. Cleaning and sign-off. The crew follows the checklist and confirms what was completed.
5. Review. After the first month, frequencies are adjusted to how the space is really used.

What should a business check before hiring? Ask whether the company is insured, whether cleaners are background-checked, whether you get the same team each visit, and whether the scope is in writing. Ask what is billed as an extra, such as floor refinishing or window washing, so the quote you compare is the full picture.

What does commercial cleaning cost?

Commercial cleaning is usually priced per visit, per hour, per square foot or as a monthly contract. As a benchmark, ISSA puts general office cleaning at about $0.09 to $0.17 per square foot. For how those models compare and what changes the price, see our guide to commercial office cleaning cost in 2026.

How Lucy’s Cleaning Home handles commercial cleaning

We clean offices and small business spaces, and we are honest about where our work ends. We handle routine office cleaning, restrooms, break rooms, floors and periodic deep cleaning. We do not do window washing or post-construction cleanup, which are specialist jobs.

We are insured, our cleaners are background-checked, and the same team comes back each visit with the same checklist. We schedule office work outside business hours when needed, so nobody loses a working day. Send us your square footage, the number of restrooms and how often you want us, and we will reply with a firm quote the same business day.

Conclusion

So, what is commercial cleaning? It is professional cleaning built around a business: a written scope, a set schedule, a focus on shared spaces and high-touch points, and a crew that works around your hours. It differs from home cleaning in scale and rules, and janitorial service is one part of it, not a separate thing. When you compare offers, read the scope, not the label.
