Every office has a job the cleaning crew walks past every night, and the crew is right to.
A standard office cleaning scope covers the nightly routine: trash, restrooms, vacuuming, floors, desks, break room, interior glass. What office cleaning does not include is a set of about a dozen jobs that need a license the crew doesn’t hold, an insurance policy they don’t carry, equipment they don’t bring, or that belong to your own staff.
Exterior windows above the first floor, duct cleaning, pest control, biohazard cleanup, mold, water damage, and building repairs are all on that list, and each one has a specific trade that handles it.
Two of those jobs get handed to the crew anyway because they look like cleaning, and for one of them the reason the crew should refuse is written into a federal rule.
What Office Cleaning Does Not Include, and Why
Start with what’s in. The routine scope is the list you’d expect, and what office cleaning includes rarely changes from one company to the next: empty the trash, disinfect the restrooms, vacuum the carpet, sweep and mop the hard floors, wipe the desks and counters, reset the break room, clean the glass you can reach.
On a first floor office that usually includes the outside of the windows too. Above the first floor it doesn’t.
Everything outside that list is outside it for one of four reasons:
- Needs a license: pesticides, refrigerant, electrical work.
- Needs a different insurance policy: blood cleanup, mold, work at height.
- Needs equipment the crew doesn’t bring nightly: duct vacuums, lifts, extraction units, dehumidifiers.
- Belongs to your own people: dishes, desk paper, the fridge.
Once you know which reason applies, you know who to call. That’s the whole trick, and it’s why the list below isn’t as long as it looks.
The Exclusion List, With Who You Call
| Job | Why it’s outside the scope | Who you call |
|---|---|---|
| Exterior windows above the first floor | Work at height, ladders, lifts or rope systems, separate insurance | A window cleaning company |
| Air duct and vent cleaning | Needs duct vacuums and HVAC access; the crew only wipes the grille faces | An HVAC or duct cleaning contractor |
| Pest control | Pesticide application needs a state license | A licensed pest control company |
| Blood, bodily fluids, sharps | Needs bloodborne pathogen training, an exposure control plan, and regulated waste disposal | A biohazard remediation company |
| Mold beyond a small surface patch | Remediation needs containment and moisture repair | A mold remediation contractor |
| Water damage, flooding, sewage backup | Needs extraction, drying equipment, and speed (24 to 48 hours) | A restoration company |
| Burnt out lights, ballasts, fluorescent tubes | Electrical work; fluorescent tubes contain mercury and go out as universal waste | An electrician or your maintenance contractor |
| Clogged drains, leaks, running toilets | Plumbing | A plumber |
| Snow, ice, parking lot, dumpster pad | Exterior grounds | A snow and landscape contractor |
| Post construction dust and debris | A one time project with its own equipment and pricing | A post construction cleaning quote, separate from the contract |
| Carpet extraction, strip and wax, high dusting | Periodic work, priced as add ons, not nightly | Your cleaner, on a separate line |
| Dishes, desk paperwork, personal items, the fridge | Other people’s property and liability | Your own staff, with a house rule |
Almost nothing on that table is something a good cleaner wouldn’t know how to do. It’s that the job needs a piece of paper, a policy, or a machine that the nightly contract doesn’t carry, and the add ons most office cleaning quotes leave out are the ones your cleaner can still do, just on their own line.
The Four Calls Worth Getting Right
The four the map of complaints always comes back to are windows, ducts, pests, and blood. Each one has a reason the crew stops, and a trade that starts.
Exterior windows above the first floor
Ground floor glass gets cleaned from the sidewalk with a pole and a squeegee, which is why it sits inside most office scopes.
One floor up, the job changes. It takes a water fed pole on a low building, a lift on a mid rise, and rope descent gear on anything tall.
That last case comes with a duty for you, not the cleaner. Under OSHA’s walking working surfaces rule (29 CFR 1910.27), before anyone uses a rope descent system on your building, the owner has to certify in writing that each roof anchorage has been tested and maintained to hold 5,000 pounds, based on an annual inspection and a full certification at least every ten years.
A window cleaning company will ask for that letter. A janitorial crew has no reason to have ever heard of it.
Who you call: a window cleaning company. Ask them how they reach each floor before they quote.
Duct and vent cleaning
Your nightly crew will dust the face of a supply grille and wipe a return cover. They won’t open the duct. Cleaning what’s inside takes negative pressure duct vacuums and agitation tools, plus HVAC access, and it’s a separate trade.
It’s also a job you probably need less often than the mailer says. The EPA’s guidance on duct cleaning says to consider it when there’s substantial visible mold inside hard surface ducts or on the heating and cooling components, when ducts are infested, or when they’re clogged enough to release dust into the rooms.
It also says wet or moldy duct insulation can’t be cleaned and has to be replaced, and that mold comes back if the moisture problem isn’t fixed. So the right first call is often the HVAC contractor who can look inside, not a duct cleaner selling a package.
Who you call: an HVAC contractor or a dedicated duct cleaning company. Ask them to show you what they found before they clean it.
Pest control
Mice in the break room ceiling, ants at the coffee station, a wasp nest over the back door. The cleaner can tell you about it, and a good one will, because they see the building empty at night. They can also remove the food sources that keep pests coming. What they can’t do is treat.
In Pennsylvania, applying pesticides for hire requires an individual applicator license and a pesticide business license from the state Department of Agriculture under the Pennsylvania Pesticide Control Act, with training, exams, and minimum liability insurance behind both.
A cleaner who sprays your baseboards with something from the hardware store is working outside their license and their insurance, and so are you if you asked.
Who you call: a licensed pest control company. Have the cleaner keep a sightings log for them; it shortens the first visit.
Blood, bodily fluids, and sharps
Someone cuts a hand in the kitchen, a nosebleed hits the carpet, a needle turns up in a restroom. It looks like cleaning, and it’s the job most likely to get handed to the crew on the spot.
The reason they should decline is OSHA’s bloodborne pathogens standard, 29 CFR 1910.1030. OSHA’s own interpretation letters say janitorial staff in non healthcare buildings are generally not considered to have occupational exposure, which sounds like good news until you follow it through.
It means an office cleaning crew has usually never been given the exposure control plan, the training, the hepatitis B vaccination offer, or the protective gear the standard requires for anyone who’s expected to clean up blood. The job doesn’t belong to them because nothing behind them was built for it.
Who you call: a biohazard remediation company, the same trade that handles trauma scenes and sewage. For an office, the visit is small and quick. Bag nothing yourself, close the room, and call.
The Jobs That Belong to Your Own People
The other half of the friction comes from the sink, and it has nothing to do with specialty work.
Cleaning contracts have excluded personal property for decades, and the language is nearly the same everywhere: the crew doesn’t wash, polish, or handle your furniture, files, cabinets, or personal items. In practice that means three things:
- Dishes: the crew wipes the counter and the sink. They don’t wash what’s in it. A sink full of mugs at 6 pm is still a sink full of mugs at 7 am, and that’s the contract working as written.
- Desk paper: cleaners wipe around what’s on a desk and never move it. A file that got dusted is a file that got touched, and nobody wants that liability.
- The fridge: nobody’s crew throws out other people’s food. That’s a house rule for your team, usually a Friday purge.
You can add any of these to a scope. A weekly fridge clear out or a dish run is a small line item. But it’s a line item, agreed in writing, and until then the sink is yours.

How to Draw the Line on a Job That Is Not on the List
Something will come up that isn’t in the table. Check it against three things, in order.
- A license or a permit: pesticides, electrical, refrigerant, anything with a certification behind it. If it needs one, call the trade.
- Equipment the crew doesn’t bring: lifts, extractors, dehumidifiers, duct vacuums. If it needs some, ask your cleaner first. Some of it, like carpet extraction and floor care, is theirs as an add on. The rest they’ll point you to.
- Something that belongs to a person: their desk, their dishes, their food. If it does, it’s a house rule, not a cleaning task.
Then ask your cleaning company for their exclusion list in writing, and ask them to put a name or a trade beside every line.
A company that has been in offices long enough already knows the window cleaner, the pest company, and the restoration outfit it would call. A medical office scope does this by design, because there the trades and the training are spelled out. An ordinary office deserves the same list, and the crew that’s in your building every night is the right one to write it.
Frequently Asked Questions
Do office cleaners clean windows?
Interior glass, yes, and on a first floor office usually the exterior too, from the sidewalk with a pole. Above the first floor, exterior windows are a separate trade with lifts or rope gear and their own insurance, so they’re excluded from a standard office scope and handled by a window cleaning company.
Do office cleaners clean air vents?
They dust the faces of grilles and return covers as part of high touch and high dusting work. They don’t open or clean inside the ducts. That takes duct vacuums and HVAC access, and the EPA says it’s mainly worth doing when there’s visible mold, pests, or dust actually blowing into the rooms.
Will the cleaning crew do the dishes?
Not unless it’s written into the scope. The crew wipes the counter and the sink, but dishes are personal property and nearly every cleaning contract excludes them. You can add a dish or fridge line as a small add on, or set a house rule for your team.
Who cleans up blood in an office?
A biohazard remediation company, not the nightly cleaning crew. Under OSHA’s bloodborne pathogens standard, office janitorial staff generally aren’t classed as having occupational exposure, so they haven’t been given the training, exposure control plan, or protective gear the job requires. Close the room and call a remediation company.
Do commercial cleaners do pest control?
No. In Pennsylvania, applying pesticides for hire requires a state applicator license and a business license from the Department of Agriculture. Cleaners can report sightings and remove food sources, but treatment belongs to a licensed pest control company.
