Janitorial vs. Commercial Cleaning: What’s the Difference?

Facility managers ask us this almost every week: what is the difference between janitorial services and commercial cleaning? The two terms get used interchangeably, and many contractors offer both, but they describe different work with different schedules, crews and pricing. Knowing which one you need keeps your proposal accurate and your building properly maintained.

The Short Answer

Janitorial services are the routine, recurring tasks that keep a building clean day to day: restrooms, trash, floors, break rooms and common areas, usually performed daily or several times a week. Commercial cleaning is the broader category of professional cleaning for business properties, and in practice it refers to the deeper, less frequent or specialty work: floor stripping and waxing, carpet extraction, high dusting, post-construction cleanup and industrial cleaning. Most facilities need both, and the best arrangement is usually one contractor who handles the daily upkeep and schedules the periodic work around it.

What Janitorial Services Include

Janitorial work is about consistency. A janitorial crew follows a fixed scope on a fixed schedule so the building looks and smells the same every morning. A typical janitorial scope covers:

• Restroom cleaning, disinfecting and restocking of paper, soap and liners
• Trash and recycling removal from offices, work areas and break rooms
• Sweeping, vacuuming and damp mopping of floors in traffic areas
• Wiping high-touch surfaces such as door handles, light switches, railings and elevator buttons
• Break room and kitchen cleanup, including counters, sinks, tables and appliance exteriors
• Dusting of desks, ledges, partitions and reachable horizontal surfaces
• Entrance and lobby upkeep, including glass doors and walk-off mats
• Day porter coverage in larger buildings, with a crew member on site during business hours

Janitorial contracts are normally priced as a monthly fee based on square footage, frequency and the number of restrooms and fixtures. Learn more about our janitorial services and office cleaning programs.

What Commercial Cleaning Includes

Commercial cleaning covers the heavier, project-based work that a nightly crew is not equipped or scheduled to do. It calls for different machines, different chemicals and often a different crew. Common commercial cleaning services include:

• Floor stripping, sealing, waxing and burnishing of VCT, tile and sealed concrete
• Carpet shampooing and hot water extraction
• Machine scrubbing of warehouse and plant floors with ride-on or walk-behind scrubbers
• High dusting of racking, beams, ductwork, light fixtures and pipes
• Post-construction cleaning after a build-out or renovation
• Loading dock, cold storage and refrigerated warehouse cleaning
• GMP and controlled-environment cleaning for life sciences and pharmaceutical facilities
• Window washing, pressure washing and other exterior work

These services are usually quoted per project or added to a janitorial contract on a monthly, quarterly or annual schedule. See our commercial cleaning services for the full list.

Which One Does Your Facility Need?

The answer depends on the type of building, how many people move through it and what the surfaces are made of. Here is how it usually breaks down.

Offices and Corporate Buildings

Offices rely on janitorial service for nightly cleaning, then add commercial cleaning for carpet extraction and hard floor refinishing a few times a year. If your lobby floors have lost their shine or the carpet shows traffic lanes no matter how often it is vacuumed, that is periodic commercial cleaning that is overdue, not a janitorial problem.

Warehouses and Distribution Centers

Large distribution centers need both at a bigger scale. Janitorial crews handle restrooms, break rooms and office areas every shift, while commercial cleaning covers machine scrubbing of concrete floors, dock cleaning and high dusting of racking. OSHA’s walking-working surfaces standard (29 CFR 1910.22) requires that floors be kept clean, orderly and free of hazards, which is why floor care in a warehouse is a safety program as much as a cleaning task. Our supply chain cleaning team cleans facilities up to 1.2 million square feet every day.

Manufacturing Plants

Plants add production-area requirements: cleaning around equipment, following lockout rules and working inside maintenance windows. The janitorial side keeps shared areas sanitary for every shift. The commercial side handles floor scrubbing, dust control and periodic deep cleans that would otherwise interrupt production. Read how we approach industrial and manufacturing cleaning.

Life Sciences and Pharmaceutical Facilities

Biotech and pharma sites need documented procedures, approved chemicals and trained staff for controlled areas. This is specialty commercial cleaning rather than routine janitorial work, even when it happens daily. See our biotechnology and life sciences cleaning page for how GMP cleaning differs.

Can One Contractor Do Both?

Yes, and for most facilities it is the better option. One contractor means one point of contact, one insurance certificate, one set of background-checked employees who know your building and one proposal that lists the daily scope and the periodic work side by side. The periodic work also gets done on time, because the same supervisor who walks the building every week is the one scheduling it.

ProClean USA has provided both janitorial and commercial cleaning since 1996. We are veteran-owned, SBA 8(a) certified, an NMSDC certified minority business enterprise and an ISNetworld member contractor, and every crew member is background-checked and trained to follow each site’s PPE and safety rules. Every contract starts with a walkthrough and a written proposal that spells out scope, frequency and cost, so there is no confusion about which tasks are routine and which are scheduled projects.

Questions to Ask Before You Sign

• Does the proposal separate the recurring janitorial scope from periodic commercial cleaning, with a frequency for each?
• Who owns and maintains the floor machines and extraction equipment?
• Are employees background-checked, and will the same crew service the building?
• What are the general liability and workers’ compensation limits, and can you see the certificate before work starts?
• How are quality inspections done, and how quickly are missed items corrected?

Frequently Asked Questions

Is janitorial the same as custodial?

Mostly, yes. Both describe routine building upkeep. “Custodial” is more common in schools, government and institutional settings, while “janitorial” is the usual term in commercial and industrial buildings.

Is commercial cleaning more expensive than janitorial services?

Per visit, usually, because it involves machines, more labor hours and specialty chemicals. Over a year, janitorial service is the larger line item because it happens every day. Bundling both with one contractor typically lowers the combined cost.

How often should commercial deep cleaning be scheduled?

It depends on traffic and flooring. Many offices refinish hard floors and extract carpet two to four times a year. Warehouses with forklift traffic often need floor scrubbing weekly or even nightly, with high dusting on a quarterly or semi-annual cycle.

Do you offer green cleaning for both?

Yes. ProClean USA is Green Clean Institute certified and can use products that meet programs such as EPA Safer Choice for routine janitorial work as well as periodic floor and carpet care. See our green cleaning services.
