The short answer: janitorial services are the recurring, day-to-day upkeep of a building — the same tasks, in the same rooms, on a set schedule. Commercial cleaning is the wider category that includes that recurring work plus the periodic and project jobs around it, like post-construction cleanup, deep floor care or a move-out. Every janitorial contract is commercial cleaning. Not every commercial cleaning job is janitorial.
In practice the two terms get used interchangeably, and that is exactly where quotes stop matching each other. If you are comparing three proposals for the same building and the numbers are wildly apart, this is usually why.
What Janitorial Services Actually Cover
Janitorial work is defined by repetition. It is the list that happens every night, or three times a week, or every Saturday — whatever frequency the building needs — and it does not change from visit to visit.
In a typical commercial building that means:
- Restrooms: fixtures, floors, mirrors, restocking consumables
- Break rooms and kitchens: counters, sinks, tables, appliance exteriors
- Trash and recycling collection
- Floors: vacuuming carpet, dust mopping and damp mopping hard surfaces
- Glass: entry doors, interior partitions, the panes people actually touch
- High-touch surfaces: door handles, light switches, elevator buttons, handrails
- Entries and lobbies, including matting
The defining feature is not the task list, though. It is the frequency attached to each line. A restroom in an occupied office generally needs daily attention; open-floor vacuuming often works at three times a week; storage and back areas can go weekly. Running the whole building on one setting means you are overpaying somewhere and underdelivering somewhere else.
What Commercial Cleaning Covers
Commercial cleaning is the umbrella. It includes everything above, and it also includes the work that happens on a cycle measured in months, or that happens once.
- Floor care cycles: stripping, waxing, burnishing, machine scrubbing
- Carpet extraction, as opposed to vacuuming
- High dusting: structure, beams, vents, light fixtures, the tops of partitions
- Post-construction cleaning after a build-out or renovation
- Move-in and move-out cleaning
- Specialised work by building type — racking in a warehouse, a defined order of operations in a medical practice, front-of-house turnaround in a restaurant
None of that belongs in a nightly visit. It belongs on the same document, with its own frequency, priced separately.
Janitorial vs. Commercial Cleaning, Side by Side
| Janitorial services | Commercial cleaning | |
|---|---|---|
| What it is | Recurring upkeep | The whole category: recurring + periodic + project |
| Frequency | Daily to weekly, fixed | Ranges from nightly to once |
| Typical tasks | Restrooms, trash, floors, glass, touchpoints | All of that, plus floor cycles, extraction, high dusting, post-construction |
| How it is priced | A monthly figure for a repeating scope | Recurring monthly figure, plus project work quoted per job |
| What it is for | Keeping a building presentable between deep cleans | Everything a commercial building needs, on one plan |
Why the Difference Matters When You Compare Quotes
Two contractors can walk the same building and hand you numbers that are hundreds of dollars apart every month, both of them honest. The gap is almost never the hourly rate. It is what each of them assumed was included.
One priced a nightly janitorial scope. The other priced a nightly scope plus quarterly floor care and twice-a-year carpet extraction. The second number is bigger and also more complete. If you sign the first one and then ask why the lobby tile looks dull in month eight, the honest answer is that nobody ever agreed to strip and wax it.
This is the practical reason to ask for the scope in writing before you ask for the price. A written scope names the task, the area it applies to, how often it happens, and what is deliberately excluded. Once you have that from every bidder, the numbers become comparable — and usually the cheapest quote stops looking cheap.
Three Questions That Expose the Gap
- What is on the periodic list, and how often? If the answer is “we handle that as needed”, it is not on the plan and it will not be budgeted.
- What is explicitly not included? A contractor who cannot answer this has not thought about your building. Kitchen hoods, grease traps, regulated medical waste and process machinery all need specialists.
- What happens when something gets missed? Listen for whether the answer is a process or a promise.
What About “Custodial”, “Porter” and “Facility Services”?
Those show up in proposals too, and they are not synonyms for each other. Knowing which one you are being sold saves a round of confusion:
- Custodial services — effectively the same work as janitorial. The word is more common in schools, government buildings and institutions, where the custodian is often on staff rather than contracted.
- Porter or day porter services — a person on site during business hours, handling restrooms, entries, spills and common areas as they happen. This is not the same as a nightly janitorial visit; it is coverage while the building is occupied. High-traffic lobbies, medical waiting rooms and busy retail often need both.
- Matron or attendant services — restroom-specific coverage during operating hours, usually in venues with heavy public traffic.
- Facility services or facility maintenance — the widest term of all. It typically bundles cleaning with things that are not cleaning: light bulb changes, filter swaps, minor repairs, landscaping, snow removal. If a proposal uses this phrase, read carefully for what is actually cleaning and what is a separate trade.
The practical point is the same one as before: the label on the proposal tells you very little. The frequency table inside it tells you everything.
Which One Does Your Building Need?
Most commercial buildings need both, on one document. The useful question is not “janitorial or commercial cleaning” — it is what belongs on the recurring list and what belongs on the periodic one.
A rough guide by building type:
- Offices — heavy recurring load, light periodic. Restrooms and break rooms drive the schedule. See office cleaning.
- Warehouses — lighter recurring load spread over more square footage, heavy periodic: racking, high dusting, floor scrubbing.
- Medical practices — recurring work that has to follow a defined order of operations, with a hard boundary around clinical waste.
- Apartment buildings — common areas only, with a seasonal spike at the entry from December through March. See apartment building cleaning.
- Restaurants — daily front-of-house turnaround before opening; the kitchen is a separate contract with a certified specialist.
Frequently Asked Questions
Is janitorial cleaning the same as commercial cleaning?
Not quite. Janitorial describes the recurring, day-to-day portion. Commercial cleaning is the broader category that also covers periodic and project work. Every janitorial contract is commercial cleaning; not every commercial cleaning job is janitorial.
Which one is cheaper?
That is the wrong comparison, and it is how buildings end up underserviced. A janitorial-only quote is smaller because it covers less. The question worth asking is what each quote includes and excludes, at what frequency — then compare.
Do I need both?
Most commercial buildings do. What changes is the balance: an office is mostly recurring, a warehouse leans periodic. The walkthrough is what settles it for your building.
What is a “written scope”?
A document listing every task, the area it applies to, how often it happens, and what is not included. It is what your facility manager checks the invoice against, and what makes a change of crew not a change in quality.
How often should a commercial building be cleaned?
It varies by area, not by building. Restrooms and break rooms in an occupied building generally need daily service; open floors often work at three times a week; storage and back areas can go weekly. That is the whole reason frequency belongs on the scope, line by line.

The Practical Takeaway
Do not shop for a label. Shop for a document. Whether the proposal on your desk says “janitorial” or “commercial cleaning” at the top matters far less than whether it names every task, every area, every frequency, and everything it leaves out.
If you want to see what that looks like for your building, our janitorial services page has the full recurring scope, and the walkthrough that produces the document is free and takes about thirty minutes.
