Ask three suppliers to quote your office and you will get one proposal for "commercial cleaning", one for "janitorial services" and one for "office cleaning" — at three different prices, for what you assumed was the same work. The prices differ because the words do, and the industry has never agreed on them.
This is not a distinction worth learning for its own sake. It is worth learning because it is the single most common reason a commercial cleaning arrangement disappoints: two parties used the same word and meant different things by it.
The honest answer: the terms overlap
There is no certification, license or industry body that defines these words. Any supplier can describe their work as either. What you can rely on is the usage pattern behind them, which is reasonably consistent even though the definitions are not.
"Janitorial" usually implies an ongoing program with a broader remit — the cleaning plus a degree of building upkeep, often at higher frequency, sometimes with someone on site. "Office cleaning" and "commercial cleaning" usually mean the cleaning itself, on a schedule, by a team that arrives, works the scope and leaves.
Neither is better. They are different amounts of building, and you should buy the one that matches how much building you have.
What people usually mean by janitorial
When a supplier uses "janitorial", they are typically describing a program sized for a building rather than a suite. The tell is what sits alongside the cleaning.
Things that usually travel under the janitorial heading:
- Daily or near-daily attendance rather than a weekly visit
- Consumables supply and restocking as part of the contract
- Waste and recycling handling across a whole building
- Light maintenance — replacing bulbs, resetting fixtures, reporting faults
- Floor care programs: stripping, sealing, burnishing, carpet extraction on a cycle
- Sometimes a day porter, on site through business hours
What people usually mean by office cleaning
Office cleaning describes the cleaning work itself, scoped to a premises and run to a schedule. It is what most single-tenant suites and small-to-mid offices actually need, and it is what Hygiene Maids does.
The scope is defined by area and task rather than by building system: workstations, reception, meeting rooms, the breakroom, the restrooms, floors and touchpoints. Some tasks happen every visit, others rotate. Nobody is on site between visits.
Which one your premises actually needs
The deciding factor is rarely floor area. It is how much of the building you are responsible for and how many people pass through it.
A suite with your own front door, your own restrooms and thirty people in it needs office cleaning at a frequency that keeps the restrooms and kitchen ahead of the traffic. A multi-tenant building with shared lobbies, corridors, elevators and public restrooms needs something closer to a janitorial program, because the work never stops during the day and somebody has to be responsible for it when it does not.
If you are somewhere in between — a growing office in a shared building, say — the useful move is to scope the part you control and be explicit about where your responsibility ends and the landlord’s begins.
Comparing quotes that use different words
Once you accept that the labels do not mean anything fixed, comparing proposals gets much easier. Ignore the heading and read for four things.
- 01Frequency — how many attendances a week, and what happens on each
- 02The every-visit list versus the rotating list, in writing
- 03Who supplies consumables, and whether that cost sits inside or outside the price
- 04What is explicitly excluded, particularly floor-care programs and anything at height
