Most business owners know the importance of keeping their office space clean, but it’s easy to assume that a quick vacuum and some light dusting are enough to get by. The truth is, surface-level cleaning doesn’t tackle the bigger issues—like allergens, bacteria, and wear-and-tear building up quietly over time.
Deep cleaning is what helps maintain a healthier, safer, and more professional space. But how often should it actually be done? The answer isn’t the same for everyone. It depends on the nature of your business, how much foot traffic you get, the layout of your space, and a few other practical details.
Let’s take a closer look at what deep cleaning includes, when it’s needed, and how a tailored schedule can save you both time and money.
What Deep Cleaning Really Means
Deep cleaning goes beyond daily or weekly janitorial tasks. While routine office cleaning focuses on visible surfaces and immediate messes, deep cleaning involves areas that are often overlooked but can accumulate the most germs and dust over time.
This includes things like sanitizing behind and under furniture, cleaning baseboards, steam cleaning carpets and upholstery, disinfecting shared electronics, and getting into vents and air ducts. In kitchens and washrooms, it’s a much more intensive process—scrubbing grout, clearing build-up from drains, and cleaning inside appliances.
It’s not about over-cleaning or wasting resources—it’s about being thorough where it counts. Arelli’s team offers customized cleaning services for offices, medical buildings, and other commercial spaces, designed to match the scale and specific layout of your workplace.
How Often is Enough?
There’s no universal rule, but there are some clear guidelines depending on your type of workplace.
In general:
- Medical clinics, daycares, and food services benefit from weekly or bi-weekly deep cleaning because of health and safety regulations.
- Busy offices with shared workspaces and high foot traffic often schedule deep cleaning monthly or quarterly.
- Depending on conditions, professional spaces like law firms, real estate offices, or low-traffic corporate spaces might only need a full deep clean two to four times a year.
What matters most is consistency. According to ServiceMaster Clean, even low-traffic spaces should be deep cleaned at least twice per year to eliminate dust and bacteria that daily cleaning won’t touch.
If you’ve recently renovated your office, gone through flu season, or had more foot traffic than usual, it’s a good time to reassess your schedule.
Signs Your Space is Due for One
Even with regular cleaning, some indicators suggest it’s time to book a deeper service:
- Lingering odors, especially in enclosed spaces like kitchens or conference rooms
- Stained or worn-looking carpets
- Allergy symptoms among staff (sneezing, coughing, itchy eyes)
- Dust buildup on vents, blinds, or electronics
- Persistent clutter in hard-to-reach places
These are often the result of areas being cleaned quickly but not thoroughly. Over time, this leads to diminished air quality, worn furnishings, and a workplace that just doesn’t feel as fresh as it should.
The Real Cost of Skipping It
It’s tempting to push deep cleaning down the list of priorities, especially when budgets are tight. But there’s a hidden cost in not doing it.
Employees are more likely to get sick when bacteria and allergens are allowed to build up, and absenteeism can add up fast. According to Vanguard Cleaning Systems, a dirty workplace can significantly lower morale and increase turnover - two things no business wants.
There’s also the issue of how your space presents to others. Clients and customers will notice a stale-smelling waiting room or a grimy washroom. First impressions can reinforce your brand—or quietly undermine it.
