The week your office closes for the holidays is the best office deep cleaning window of the year. The building is empty, so machines can run in every room, carpet can dry with nobody walking on it, and the crew can reach the areas a nightly visit never touches. The catch is the calendar: providers book that week early, so plan in November, not on December 20.
This guide is for office and facility managers planning a year-end deep clean. The office cleaning frequency guide covers the periodic layer of the schedule; this post is about using the shutdown to clear that layer in one go. Below: which tasks to book, a booking timeline, and how to prepare the space before the crew arrives.
Why the shutdown week suits office deep cleaning
Most deep cleaning tasks need two things a working office cannot give: open floor space and drying time. Carpet extraction leaves fibres damp for hours. Floor machines are loud and need rooms cleared. High dusting puts a lift or ladder in the middle of a corridor. On a normal night the crew works around all of this. During a shutdown, none of it is in the way.
There is also a planning advantage. One empty week lets several tasks run back to back with a single round of access arrangements, instead of four separate after-hours bookings spread across the winter. If your office never fully closes, the same logic applies to a long weekend or a quiet week between projects.
What to include in a year-end office deep cleaning
Treat the list below as a menu, not a package. Pick by traffic and by what your building skipped this year.
| Task | Why the shutdown week works |
|---|---|
| Carpet extraction | Carpet dries undisturbed, with no boots crossing it the next morning |
| Hard-floor scrub and recoat, or strip and wax | Finish needs rooms closed to traffic while it dries and hardens |
| High-level dusting | Vents, ledges and fixtures need clear floors for ladders or lifts |
| Interior glass and partitions | Meeting rooms and glass walls are free all day, not between bookings |
| Upholstery and office chairs | Fabric dries overnight with nobody sitting down |
| Kitchen deep clean and fridge clear-out | The fridge can be emptied, and appliances cleaned inside and out |
| Washroom detail work | Grout, partitions and fixture bases get time a nightly visit lacks |
None of this is part of the regular nightly route. What commercial cleaning includes explains the line between nightly work and extras, so you can check what your current agreement already covers before booking more.
A booking timeline for a year-end deep clean
- Early November: walk the office and list what needs deep work. Get a written quote per task, with dates.
- Mid November: confirm the booking, the access plan and the alarm arrangements. Tell building management, and ask about freight elevator and parking for equipment.
- Last week before the shutdown: prepare the space with your staff, using the checklist below.
- Shutdown week: the work runs. Agree beforehand who is reachable if the crew finds a problem, such as a leak behind a fridge.
- First day back: walk the office against the task list before everyone settles in. The commercial cleaning inspection guide gives a route and a simple way to score what you find.
A winter caveat on floor work
Salt season complicates floor refinishing. Entrance areas take salt and grit all winter, so the best time to refinish them is before the salt arrives, as the guide to winter floor care for commercial buildings explains. Interior zones away from the doors are a different story: they can be scrubbed, recoated or refinished during the shutdown, provided the heat stays on while the building is closed, because finish dries slowly in a cold room.
Ask two questions before booking floor work for the closure: what temperature the building holds over the holidays, and whether the job is a full strip or a lighter recoat. The guide to when to strip and wax and when to recoat helps you tell the difference before the quote arrives.

How to prepare the office before the deep clean
A prepared office gets more out of the same booked hours. In the last week before the shutdown, ask staff to:
- Clear desks and take personal items home, so surfaces and chairs can actually be cleaned
- Lift boxes and cables off the floor in any room booked for carpet or floor work
- Empty or label everything in the fridge, and agree that unlabelled items go out
- Take plants off window sills and filing cabinets that are due for dusting
- Leave IT equipment plugged in, and tell the provider the crew should not unplug anything
Then settle access: who holds keys and alarm codes, which doors the crew uses, and the name and number of one contact on each side. Put the task list, the dates and the access plan in one email so there is a single record.
What does a year-end office deep cleaning cost?
Each task is priced on its own, mostly from labour hours, equipment and floor area, so the total depends on your menu rather than on a flat rate. Booking several tasks into one empty week often costs less than spreading the same work across separate after-hours visits, because the crew sets up once. The factors behind the numbers are covered in what affects an office cleaning quote. Ask for the quote per task, so you can trim the menu instead of accepting or rejecting one bundled price.
Frequently asked questions
Is a deep clean included in my regular cleaning contract?
Usually not. Nightly service covers recurring work, and deep cleaning tasks are booked as extras on their own dates. Check your scope of work first, then quote the year-end list separately.
Can office deep cleaning go ahead if some staff work through the holidays?
Yes, with zoning. Give the provider a list of occupied rooms and dates, and sequence the work so loud or wet tasks happen away from anyone working. A skeleton crew in one corner rarely blocks the rest of the building.
How long does the office need to stay empty?
It depends on the menu. Extraction and upholstery usually need overnight drying, while floor finish needs longer, especially in a cool building. Ask the provider for a day-by-day plan so you know which rooms are usable when.
We never close. When should we book deep cleaning instead?
Use the quietest block you have: a long weekend, a statutory holiday or a slow week. The tasks split across several nights if they must; the shutdown week is simply the cheapest and easiest version of the same plan.
Book the empty week before it fills
If you tell us your floor types, rooms and shutdown dates, we can walk the space, write the task list and hold the dates. See our deep cleaning service, or request a free estimate and ask for a year-end office deep cleaning quote.
