Most businesses call a cleaning company and say they need ‘janitorial service.’ Then they are surprised when the vendor shows up for a routine sweep and does not touch the carpet, the windows, or the grout.
The problem is that ‘janitorial service’ is not one thing. It is a category with multiple types underneath it — each with a different scope, frequency, price, and purpose.
Here is every major type of janitorial service explained clearly, so you know exactly what to ask for and what to expect.
1. Routine Janitorial Service
The most common type. A cleaning crew visits your facility on a scheduled basis — daily, several times a week, or weekly — to handle the standard upkeep that keeps a commercial space functional and presentable. This is what most people mean when they say ‘we have a cleaning company.’
Best for: Offices, schools, retail stores, gyms, government buildings — any space with regular foot traffic
Frequency: Daily, 3–5x per week, or weekly depending on facility size and use
Typical cost: $0.08 to $0.15 per sq ft per visit for standard offices
What it typically covers:
- Trash removal and liner replacement
- Vacuuming and mopping all floor surfaces
- Restroom sanitizing and supply restocking
- Wiping down desks, counters, and high-touch surfaces
- Cleaning breakrooms and common areas
- Spot-cleaning interior glass
💡 Pro Tip
Routine janitorial service keeps a space consistently clean — but it does not replace periodic deep cleaning. Most facilities need both, layered together on a schedule.
2. Deep Cleaning Service
A thorough, intensive clean that goes beyond the scope of routine janitorial work. Deep cleaning addresses the buildup, grime, and neglected areas that regular visits do not reach — behind equipment, inside appliances, grout lines, baseboards, vents, and more.
Best for: Any commercial space that needs a reset — before a new tenant moves in, after a seasonal closure, or when routine cleaning has fallen behind
Frequency: Quarterly, semi-annually, or as needed — not a recurring weekly service
Typical cost: $0.15 to $0.30 per sq ft depending on facility type and condition
What it typically covers beyond routine cleaning:
- Scrubbing grout lines and tile surfaces
- Cleaning inside and behind appliances
- Washing walls and baseboards
- Detailed cleaning of vents and light fixtures
- Sanitizing inside cabinets and storage areas
- Full restroom descaling and deep disinfection
⚠️ Warning
Do not confuse deep cleaning with routine service. If you hire a routine janitorial vendor expecting a deep clean, you will be disappointed — and they will be underpaid for work that takes significantly longer and requires different products.
3. Floor Care and Maintenance
Specialized floor cleaning that goes beyond routine mopping. Different floor types require different methods — carpet extraction, hard floor stripping and waxing, buffing and burnishing, tile scrubbing, and concrete sealing all fall under floor care. This is almost always a separate service from routine janitorial.
Best for: Any commercial facility with carpeted areas, VCT tile, polished concrete, natural stone, or high-traffic hard floors
Frequency: Monthly for buffing and maintenance, quarterly for extraction and deep scrubbing, annually for stripping and recoating
Typical cost: $0.05 to $0.20 per sq ft depending on floor type and service
Common floor care services:
- Carpet extraction and hot water extraction
- VCT floor stripping and waxing
- Hard floor buffing and burnishing
- Concrete grinding, sealing, and polishing
- Natural stone care and restoration
- Grout cleaning and sealing
💡 Pro Tip
Floors are often the most visible indicator of a clean facility. Scheduling quarterly carpet extraction and periodic hard floor maintenance separately from your routine janitorial contract keeps them looking professional year-round.
4. Window Cleaning
Professional cleaning of interior and exterior glass surfaces. Interior window spot-cleaning is sometimes included in routine janitorial contracts, but full interior and exterior window washing is almost always a separate, specialized service requiring different equipment and safety protocols.
Best for: Office buildings, retail storefronts, medical facilities, and any building where clean, clear glass matters for first impressions
Frequency: Monthly for interior, quarterly or semi-annually for exterior
Typical cost: $2 to $7 per pane for standard commercial windows; larger or high-rise glass priced differently
What professional window cleaning covers:
- Interior glass surfaces — full cleaning, not just spot-wiping
- Exterior glass — requires appropriate equipment for building height
- Window frames, tracks, and sills
- Glass entry doors and lobby partitions
- Skylights and atrium glass where accessible
⚠️ Warning
Exterior window cleaning above ground level requires licensed operators with proper safety equipment and liability insurance. Never hire an uncertified vendor for elevated window work — the liability exposure is significant.
5. Restroom Sanitization Service
A dedicated, high-frequency service focused specifically on commercial restrooms. While restroom cleaning is included in routine janitorial service, some high-traffic facilities need standalone restroom sanitization performed multiple times daily — separate from the regular cleaning schedule.
Best for: High-traffic retail locations, event venues, airports, transit facilities, food service operations, and medical facilities
Frequency: Multiple times daily for high-traffic facilities, or as a standalone daily service
Typical cost: Priced per restroom visit — typically $15 to $40 per restroom per dedicated visit
What dedicated restroom sanitization includes:
- Full sanitization of all fixtures between routine cleaning visits
- Supply restocking — paper, soap, air freshener
- Floor spot-cleaning and disinfection
- Mirror and surface wiping
- Odor control and ventilation check
6. Post-Construction Cleaning
A specialized one-time or phased clean performed after construction, renovation, or buildout work. Construction sites leave behind fine dust, debris, adhesive residue, paint overspray, and materials that standard cleaning crews are not equipped to handle. Post-construction cleaning requires specific products, equipment, and often multiple visits.
Best for: Any commercial space after construction, renovation, tenant improvement, or major equipment installation
Frequency: One-time or phased — typically two to three rounds: rough clean, final clean, and touch-up before occupancy
Typical cost: $0.15 to $0.50 per sq ft depending on scope and level of construction
What post-construction cleaning typically includes:
- Removal of construction dust from all surfaces, including above ceiling tiles
- Cleaning and polishing new fixtures, appliances, and cabinetry
- Removing adhesive residue, paint overspray, and protective film
- Floor cleaning and preparation — vacuuming, scrubbing, and polishing
- Window and glass cleaning — inside and outside
- Final touch-up clean before client walkthrough
💡 Pro Tip
Schedule your post-construction clean in phases, not all at once. A rough clean before trades are finished, a detailed clean after, and a final touch-up the day before occupancy produces far better results than one big clean at the end.
7. Green and Eco-Friendly Cleaning
Janitorial service that uses EPA-registered, low-VOC, biodegradable, and environmentally certified cleaning products and methods. Green cleaning reduces chemical exposure for building occupants, supports sustainability goals, and is increasingly required for LEED-certified buildings and corporate sustainability programs.
Best for: LEED-certified buildings, corporate offices with ESG commitments, schools and childcare facilities, healthcare environments, and any business with documented sustainability requirements
Frequency: Same frequency as routine janitorial service — daily, weekly, or as needed
Typical cost: Typically 10–20% premium over standard janitorial rates due to certified product costs
What distinguishes green cleaning from standard service:
- EPA Safer Choice or Green Seal certified cleaning products only
- Microfiber systems that reduce chemical usage and water consumption
- HEPA-filter vacuums that capture fine particles instead of recirculating them
- Documented product ingredient transparency for compliance reporting
- Reduced or eliminated use of bleach and harsh chemical disinfectants
💡 Pro Tip
If your building is LEED-certified or pursuing certification, green cleaning is not optional — it is part of maintaining that certification. Confirm your vendor can provide documented product compliance before signing any contract.
8. Medical and Healthcare Facility Cleaning
Specialized janitorial service designed specifically for clinical and healthcare environments. This is not standard commercial cleaning with a different name — it requires EPA-registered hospital-grade disinfectants, strict protocols for infection prevention, documented compliance with OSHA and CDC guidelines, and trained staff who understand the difference between cleaning, sanitizing, and disinfecting in a clinical context.
Best for: Medical offices, dental practices, outpatient clinics, urgent care centers, laboratories, physical therapy facilities, and any space where clinical care is delivered
Frequency: Daily at minimum — often multiple times daily for procedure rooms and high-contact areas
Typical cost: $0.15 to $0.35 per sq ft per visit — significantly higher than standard office cleaning
What medical cleaning requires that standard janitorial does not:
- EPA-registered hospital-grade disinfectants with documented dwell times
- Separate color-coded cleaning tools for different zones — exam rooms, restrooms, common areas
- Trained staff who understand isolation precautions and biohazard protocols
- Documented cleaning logs for compliance and infection control audits
- Background-checked employees — often required by facility compliance standards
⚠️ Warning
Never hire a standard janitorial company for a medical facility without confirming they have specific healthcare cleaning training and protocols. The compliance and liability risks of using unqualified vendors in clinical environments are significant.
9. Disinfection and Sanitization Service
A targeted service focused specifically on killing pathogens on surfaces — not general cleaning. Disinfection services use EPA-registered products with documented kill claims for specific organisms, applied to high-touch surfaces throughout a facility. This became standard in many industries after 2020 and remains a regular service for healthcare, food service, childcare, and high-density office environments.
Best for: Healthcare facilities, schools, childcare centers, food service operations, gyms, and any high-traffic space with elevated infection risk
Frequency: Daily for high-risk environments, weekly or as-needed for standard commercial spaces
Typical cost: $0.05 to $0.15 per sq ft for surface disinfection — electrostatic spraying priced per sq ft of coverage
Disinfection methods used in commercial settings:
- Manual application with EPA-registered disinfectant and microfiber — most common, most controlled
- Electrostatic spraying — charges disinfectant particles to wrap around surfaces for more complete coverage
- UV-C light disinfection — used in healthcare settings for surface and air pathogen reduction
- Fogging — aerosolized disinfectant for large area coverage, requires full evacuation
💡 Pro Tip
Disinfection is not the same as cleaning. Surfaces must be cleaned first — removing dirt and organic matter — before disinfectants can work effectively. A vendor offering disinfection without cleaning first is skipping a critical step.
Which Type of Janitorial Service Does Your Business Actually Need?
Most commercial spaces need more than one type — but not all at the same frequency or from the same vendor. Here is a simple way to think about it:
▪️Standard office, retail, or warehouse: Routine janitorial service as your foundation, with floor care added quarterly and a deep clean once or twice a year.
▪️Medical or dental office: Healthcare facility cleaning with daily service, EPA-registered disinfectants, and documented compliance — not standard janitorial with a price markup.
▪️After a renovation or buildout: Post-construction cleaning before any other service begins. Routine janitorial starts after the space is clean and occupied.
▪️LEED-certified or sustainability-focused building: Green cleaning with certified products and documented compliance reporting.
▪️High-traffic public-facing space: Routine janitorial plus dedicated restroom sanitization at higher frequency, especially during peak hours.

CONCLUSION
Janitorial service is not one size fits all. The right type depends on your facility, your industry, your foot traffic, and what your clients, tenants, or patients expect when they walk through the door.
Know what each type covers before you call a vendor — and you will get a far more accurate quote, a better contract, and a cleaner result.
