Custodial services vs janitorial services vs facility services: what is the difference?
One solicitation asks for custodial services, a second vendor quotes janitorial services, and a third offers facility services. Before you compare them, you need to know whether they describe the same work.
National Cleaning Group ·
Custodial services and janitorial services are two names for the same job: recurring cleaning of a building. The difference is mostly who is speaking. Schools and government say custodial. Offices and property managers say janitorial. Facility services is the one that actually means something broader, because it adds maintenance and building operations to the cleaning.
Below: plain definitions, a comparison table, the duties that hide behind the word "custodian", and the scope lines that matter more than any of the three labels.
What custodial services means
Custodial services are the routine cleaning and care of a building, done on a set schedule. A custodian keeps the building in its everyday condition: trash out, restrooms clean and stocked, floors swept, mopped, and vacuumed, surfaces dusted.
The word comes from "custody", the idea of looking after a place. That is why it shows up in public institutions. School districts employ custodians. Universities run custodial departments. Federal, state, and city solicitations commonly ask for custodial services, even when the work described is identical to an office janitorial contract.
What janitorial services means
Janitorial services are the same recurring cleaning, bought as a contract by a private company or property manager. The word is standard in commercial real estate and in the cleaning industry itself. The federal industry code for the work, NAICS 561720, is titled Janitorial Services, and "custodial" solicitations commonly use the same code.
A janitorial contract usually covers nightly cleaning, periodic floor work, and sometimes a day porter during open hours. Our page on what janitorial services include lists the base tasks and the common add-ons.
Custodial vs janitorial vs facility services, side by side
The first two columns describe nearly the same work. The third is a different kind of contract.
| Custodial services | Janitorial services | Facility services | |
|---|---|---|---|
| Who usually says it | Schools, universities, government agencies | Private offices, property managers, retail, medical offices | Large campuses, portfolios, corporate real estate |
| Core work | Recurring cleaning: trash, restrooms, dusting, floors | Recurring cleaning: trash, restrooms, dusting, floors | Cleaning plus maintenance and building operations |
| Common extras | Room setups, unlocking, daytime spill response (if written) | Day porter, floor care, disinfection | Repairs, HVAC oversight, security, landscaping, mailroom |
| Typical staff | In-house custodians or a contractor | Contractor crews | Mix of self-performed staff and subcontractors |
| How it is bought | Solicitation or bid, often with a set scope | RFP or proposal after a walkthrough | Larger RFP, sometimes a managed contract |
If you are comparing a custodial bid with a janitorial bid, compare the scopes, not the titles. If one vendor offers facility services, ask which parts they perform with their own staff and which they subcontract.
How a custodial solicitation differs from a janitorial RFP
The work is the same, but the paperwork usually is not. A public custodial solicitation and a private janitorial RFP tend to differ in four places, and knowing them helps whichever side of the desk you sit on.
The scope is fixed. A school district or agency typically publishes the scope and frequencies and asks bidders to price exactly that. A private buyer more often invites each vendor to walk the building and propose a scope. Fixed scopes compare more easily. They also carry every old mistake forward, so read the last contract's scope before you reissue it.
Wages may be set for you. Many public contracts carry wage rules. Federal service contracts, for example, generally fall under the Service Contract Act and come with a wage determination for the area. Bidders price to those rates, which narrows the spread between bids and makes labor hours the main thing to compare.
The calendar drives the schedule. Schools have breaks, testing weeks, and summer, and the heavy floor work lands in those windows. A private office runs the same five nights all year.
Award rules are formal. Lowest responsive bid, best value scoring, required forms, and a mandatory site visit are common. Miss a form and a good bid is out.
If you are writing a private RFP, borrow the best part of the public model: one scope, priced the same way by every bidder. Our janitorial RFP guide shows how.
What facility services adds
Facility services is the umbrella term for keeping a building operating, not just clean. Cleaning is one piece. Maintenance, repairs, and building systems are the rest.
Most buyers do not need the whole umbrella from one vendor. What many do want is the overlap: the small maintenance items that crews walk past every night, like a dead lamp, a stained ceiling tile, or a loose dispenser, handled by the same company that cleans. That is light facility maintenance, and it sits on the same contract as the cleaning. Bigger work (electrical, plumbing, HVAC) stays with licensed trades.
If a vendor pitches the full umbrella, ask who actually turns up for each piece. Which services do their own employees perform, and which go to subcontractors? Who do you call when the cleaning is fine but the restroom faucet is not? And does one person answer for both, or do you get a second contact for maintenance? The answers tell you whether you are buying one company or a switchboard.
What the title "custodian" hides
This is the part every definition skips, and it is the one that causes trouble. An in-house custodian, especially in a school or public building, often does far more than clean. Over years the job collects duties nobody wrote down. When the building moves to a contractor, or when a contract is rebid, those duties do not transfer on their own.
Before you write the scope, ask your current custodial staff or building manager what they do in a normal week that is not cleaning. Typical answers:
- Unlocking and locking doors, and arming or disarming alarms.
- Setting up and resetting rooms for meetings, events, or testing.
- Responding to daytime spills, sick-student cleanups, and restroom problems.
- Accepting deliveries and moving supplies.
- Changing lamps, swapping ceiling tiles, and reporting leaks.
- Checking doors, windows, and lights at close.
- Salting or clearing the steps at the door before anyone arrives.
Each of these needs a decision: add it to the cleaning scope, put it on a light maintenance line, cover it with daytime porter hours, or keep it with your own staff. Leaving it unassigned is how a building ends up with no one to call when a room needs setting up at 7 a.m.
Put this in the scope, whatever the word
The label on the contract decides nothing. These lines decide what you get:
- Every area by type (offices, classrooms, restrooms, corridors, break rooms), with cleanable square feet.
- Tasks for each area with frequency: nightly, weekly, monthly, quarterly.
- Service nights per week and the hours the crew can be in the building.
- Daytime coverage: porter or day custodian hours as clock times.
- Periodic floor work as dated lines: burnish, scrub and recoat, strip, carpet extraction.
- Light maintenance items the contractor handles, and what it only reports.
- The non-cleaning duties from the list above, each assigned.
- Who supplies paper, soap, liners, and chemicals.
- How quality is inspected and how you see the results.
- Insurance requirements and key and alarm control.

Frequently asked questions
What does custodial services mean?
Custodial services means the routine cleaning and care of a building: emptying trash, cleaning restrooms, dusting, vacuuming and mopping, restocking supplies, and keeping floors maintained. The word is most common in schools, universities, and government buildings, where the staff who do it are called custodians. In practice it covers the same work a private company would call janitorial services.
Is custodial the same as janitorial?
For buying purposes, yes. Both describe recurring building cleaning. Some people use custodial to suggest broader care of a building, including small tasks like unlocking doors or setting up rooms, but there is no standard definition that makes those duties automatic. If you want them, list them in the scope, whichever word the contract uses.
What does a maintenance custodian do?
A maintenance custodian is usually an in-house role that combines cleaning with small repairs: changing lamps, replacing ceiling tiles, tightening hardware, clearing simple clogs, and reporting bigger problems to licensed trades. When a building moves to a contractor, that mix is often split between the cleaning contract and a light maintenance line, so each task still has an owner.
What are facility services?
Facility services is the broad term for the work that keeps a building running: cleaning, maintenance, repairs, and sometimes security, landscaping, mailroom, or HVAC management. A facility services provider may self-perform all of it or manage subcontractors. Buyers often use the term when they want cleaning and maintenance handled under one contract with one point of contact.
How many hours do custodial crews work?
Contract custodial and janitorial crews most often work evening or night shifts after the building empties, commonly a few hours per service night depending on the building size and scope. Daytime coverage, for restrooms, spills, and lobbies, is handled by a day porter or day custodian on set hours. The hours should appear in the proposal as labor hours per night.
