When it comes to maintaining a productive and healthy workplace, keeping the office clean is non-negotiable. But while daily tidying keeps things presentable, there comes a time when a deeper clean is necessary. Whether it’s tackling built-up grime, refreshing neglected corners, or ensuring every surface sparkles, a deep clean can transform your office. The big question most business owners or facility managers ask is: How long does it take to deep clean an office? The answer isn’t one-size-fits-all—it depends on several factors like office size, condition, and the scope of the job. Let’s break it down so you can plan accordingly.
What Is a Deep Clean, Anyway?
Before diving into timelines, let’s clarify what “deep cleaning” means. Unlike a standard cleaning—think vacuuming, wiping desks, and emptying trash—a deep clean goes beyond the surface. It’s a thorough, top-to-bottom scrub that tackles areas often overlooked in routine maintenance. This might include shampooing carpets, scrubbing baseboards, disinfecting high-touch areas, cleaning inside appliances, and even dusting ceiling fixtures. It’s the kind of cleaning that leaves no stone unturned, ensuring your office isn’t just tidy but truly sanitized and refreshed.
Because of its comprehensive nature, deep cleaning takes more time and effort than a quick spruce-up. So, how long should you expect it to take? Let’s explore the key factors that influence the timeline.
Factor 1: Office Size
The most obvious variable is the size of your office. A small office with 1,000 square feet will naturally take less time than a sprawling 10,000-square-foot corporate space. As a general rule of thumb, professional cleaners can deep clean about 200 to 400 square feet per hour, depending on the complexity of the job.
For example:
- A 1,000-square-foot office might take 3 to 5 hours.
- A 5,000-square-foot office could range from 12 to 25 hours.
- A 10,000-square-foot space? You’re looking at 25 to 50 hours or more.
These estimates assume a single cleaner. If you hire a team, the time shrinks significantly—more on that later.
Factor 2: Office Layout and Features
Size isn’t the only thing that matters; the layout plays a huge role too. An open-plan office with minimal furniture might be quicker to clean than a space packed with cubicles, conference rooms, and break areas. Features like carpeted floors (which may need shampooing), large windows (requiring washing), or a kitchenette (with appliances to scrub) add time to the process.
For instance, cleaning a kitchen area might tack on an extra hour or two, especially if the fridge needs defrosting or the microwave is caked with last month’s spills. High ceilings with light fixtures that need dusting? Add another hour. The more “extras” your office has, the longer the deep clean will take.
Factor 3: Condition of the Space
How long has it been since your last deep clean? An office that’s been neglected for years will take longer than one that gets a thorough overhaul every six months. Dust bunnies under desks, sticky floors, or stained upholstery slow things down as cleaners spend extra time restoring the space to pristine condition.
If your office is in decent shape, the process might stay on the shorter end of the estimate. But if it’s a “we-haven’t-deep-cleaned-since-the-pandemic” situation, expect the upper range—or more.
Factor 4: Team Size and Efficiency
Are you relying on your in-house staff, or hiring a professional cleaning crew? A solo cleaner will take longer than a team of three or four. Professional services often bring multiple workers, specialized equipment, and streamlined processes, cutting the time in half (or more). For example, that 5,000-square-foot office might take one person 20 hours but a team of four just 5 to 7 hours. Efficiency matters too—pros know how to prioritize tasks and avoid wasting time.
Typical Timelines for Deep Cleaning
Let’s put it all together with some real-world examples:
- Small Office (1,000–2,000 sq ft): 3–8 hours with one cleaner; 2–4 hours with a team.
- Medium Office (3,000–5,000 sq ft): 10–25 hours solo; 5–10 hours with a team.
- Large Office (10,000+ sq ft): 25–50+ hours solo; 10–20 hours with a team.
These are rough estimates. A cluttered office with lots of furniture or heavy foot traffic areas might push the timeline higher, while a minimalist space could come in under.
Planning the Deep Clean
Timing is everything. Most businesses schedule deep cleans outside regular hours—think evenings, weekends, or holidays—to avoid disrupting work. A small office might be done overnight, while a larger space could require a full weekend. If downtime isn’t an option, some cleaning companies offer phased services, tackling one section at a time over several days.
Pro tip: Get a quote from a cleaning service ahead of time. They’ll assess your space, ask about your needs, and give you a more precise estimate. Plus, they can flag any areas (like that mystery stain in the break room) that might need extra attention.
Why Deep Cleaning Is Worth the Time
You might wonder if it’s worth dedicating hours—or even days—to a deep clean. The answer? Absolutely. A spotless office boosts employee morale, impresses clients, and reduces the spread of germs. Studies show clean workspaces can even improve productivity. Plus, regular deep cleaning extends the life of carpets, furniture, and fixtures, saving you money in the long run.
So, while the time investment varies, the payoff is a healthier, happier office that reflects your business in the best light.
5 FAQs About Deep Cleaning an Office
1. How often should an office be deep cleaned?
It depends on usage, but most experts recommend every 6–12 months for a full deep clean. High-traffic offices or those with lots of employees might need it quarterly. Pair it with daily or weekly maintenance to keep things manageable.
2. Can employees deep clean the office themselves?
They can, but it’s not always the best idea. Employees aren’t trained cleaners, and they might miss spots or take longer than pros. Plus, it pulls them away from their actual jobs. Hiring professionals is usually more efficient and effective.
3. What’s the difference between deep cleaning and regular cleaning?
Regular cleaning handles day-to-day upkeep: vacuuming, dusting, trash removal. Deep cleaning digs into the nitty-gritty—think scrubbing grout, washing windows, or disinfecting every doorknob. It’s more intensive and less frequent.
4. How much does it cost to deep clean an office?
Costs vary by location and scope, but expect $0.10–$0.50 per square foot. A 2,000-square-foot office might run $200–$1,000. Get a few quotes for accuracy, as extras like carpet cleaning or upholstery can increase the price.
5. Will a deep clean disrupt office hours?
It doesn’t have to. Many companies schedule deep cleans after hours or during low-activity periods like weekends. For larger offices, you can break it into phases—cleaning one area at a time—to minimize disruption.
