What Is Janitorial Cleaning and Why Businesses Rely On It

That building with the clean lobby, shiny floors, and conference rooms that smell fresh is probably something you've seen before. Or maybe you've had the opposite experience: elevator buttons that stick, trash cans that are too full, and that smell that makes people turn around at the door.

‍

What makes them different? Cleaning service for businesses. Not just a quick wipe-down or weekend sweep, but a full system that keeps commercial buildings running smoothly.

‍

If you own or manage a building or property in Los Angeles County, whether it's in West Hollywood, Santa Monica, El Segundo, or Pasadena, you have a valuable asset. It needs protection, just like any other investment. That's exactly what office janitorial services do, which is why 89.8% of businesses hire outside companies to do their cleaning.

‍

The Real Meaning of Janitorial Cleaning (It's More Than You Think)

Let's get something straight right away. Cleaning the office isn't just someone pushing a mop around after hours.

‍

It's a specialized service that includes regular upkeep of business buildings. Think of it as medicine that keeps your property healthy. The International Sanitary Supply Association (ISSA) says that professional cleaning services include:

‍

• Cleaning every day: Taking out the trash, cleaning the surfaces, and cleaning the bathrooms
• Cleaning programs for floors include vacuuming, mopping, stripping, waxing, and polishing.
• Cleaning that requires special tools, like washing windows, pulling up carpets, and pressure washing
• Sanitation rules: disinfecting surfaces that are touched a lot and controlling germs
• Building upkeep: changing light bulbs, making small repairs, and reporting on inspections

‍

The global market for janitorial services was worth $288.76 billion in 2024 and is expected to grow to $367.48 billion by 2030. Why is this market growing so quickly? Because building managers like you have figured out something very important: hiring professionals to clean isn't an expense; it's part of the building's infrastructure.

‍

Why Your Building Actually Needs Professional Office Janitorial Services

‍

Most property management classes won't tell you this: your building is always under attack. Not from vandals or the weather (though those are important too), but from everyday use that lowers the value of your asset.

‍

The Unseen Cost of Cleaning by Hand

Let's talk about numbers. Depending on the size of the building, about 400 to 600 people go through it every day. Every year, each person brings in:

‍

• 0.5 pounds of dirt and dust on their shoes.
• A lot of bacteria from outside surfaces
• Things that cause allergies, pollution, and contamination

‍

This buildup becomes a bigger problem if it isn't cleaned properly by a janitor. According to research from the Cleaning Industry Research Institute, buildings that don't get professional maintenance lose 5–10% of their value in the first three years because they wear out faster.

You're not just dealing with cosmetics. You're dealing with:

Health effects: The Environmental Protection Agency says that bad indoor air quality costs U.S. businesses between $20 and $60 billion a year in lost productivity. When your tenants' workers are sick, they don't stay with you as long.

‍

Risk of liability: The most common reason for commercial property insurance claims is slip-and-fall accidents. By taking care of floors regularly and cleaning up spills right away, professional janitorial services cut down on these problems by 30 to 40%.

‍

Property damage: That dirt that builds up in elevator tracks? Not only is it ugly, but it also speeds up mechanical failure. The same goes for dirty HVAC vents, carpets that haven't been cleaned, and hard floors that haven't been cared for.

‍

What Landlords Should Learn from Building Managers

I've worked with property managers all over Los Angeles County, and the ones who are good at their jobs all know one thing: cleaning is a way to manage risk.

‍

Think about this situation: You want to rent 5,000 square feet to a tech startup. They walk through your building in Santa Monica and compare it to a property in El Segundo. The two are in similar places and have similar prices. What's the difference? Your competitor's building is spotless all year long thanks to their office cleaning services, which keep it looking like a "new building."

‍

Your property? It looks old. Your competitor signs the startup.

‍

That's $15,000 to $20,000 a month in rent that you won't get because you didn't take care of the property. Professional cleaning would have stopped this from happening.

‍

The Science Behind Good Cleaning Services

When professional office janitors clean, they don't just guess what to do. The industry has changed a lot, especially after 2020, when everyone in the building was worried about their health.

Cleaning protocols that really work in the modern world

‍

A 2024 study by the International Executive Housekeepers Association found that the "Four-Tiered Cleaning Approach" is the best way to run a cleaning program.

‍

Tier 1: Daily High-Touch Cleaning: The handles on doors, the buttons in elevators, the reception desks, the light switches, and the handrails. These surfaces get dirty in just a few minutes, so they need to be cleaned several times a day. Employees take 30% fewer sick days when buildings follow the right rules.

‍

Tier 2: Deep cleaning regularly. It's not about making things look clean; it's about getting rid of germs and dirt on porous surfaces. Without proper extraction cleaning, carpets, upholstery, and textured floors can have up to 200,000 bacteria per square inch.

‍

Tier 3: Specialized Maintenance The lobbies, elevators, and stairwells in your building get a lot more wear and tear than other areas. These areas need special products and methods that keep things clean while also protecting the materials.

‍

Tier 4: Preventive Systems: This is where professional services stand out from amateur ones. Taking care of your floors ahead of time (sealing, protecting, and maintaining) can make them last three times longer. Cleaning your ducts regularly can make your HVAC system work 20–30% better.

‍

The Green Cleaning Movement

You can't ignore this trend: The U.S. Green Building Council says that 73% of business tenants now think about how their office space affects the environment when they choose it.

‍

• Modern office cleaning services use products that are biodegradable and safe for the environment.
• Doesn't have any harsh chemicals that can hurt surfaces
• Better for the air inside.
• In line with LEED certification requirements

‍

Properties that use green cleaning programs save an average of 11% on operating costs because they are more efficient and use fewer chemicals.

‍

What Really Happens When You Hire a Professional Janitor

Let's go over what you can expect when you work with real office cleaning services. Cheap contractors promise things that good contractors don't actually deliver.

‍

The Methodical Approach

Professional cleaning companies work on set schedules that include:

‍

Daily Operations (scheduled or after hours):

‍

• Taking out the trash and recycling, and replacing the liner
• Cleaning the bathroom (toilets, urinals, sinks, mirrors, and floors)
• Cleaning and sanitizing the break room
• Disinfecting surfaces that get a lot of touch
• Cleaning the entrance mat and sweeping or mopping the floor
• Setting up and cleaning the conference room
• Cleaning the surfaces of cubicles and workstations

‍

Tasks for the week:

‍

• Thorough vacuuming of all carpeted areas
• Taking care of hard floors (scrubbing them with a machine when necessary)
• Cleaning the glass and partitions inside
• Cleaning kitchen appliances
• Cleaning the trash can
• Deep Clean Once a Month Services:
• Cleaning blinds and vents
• Cleaning furniture in detail
• Dusting high places like ceiling corners and light fixtures
• Cleaning the baseboards and spots on the walls

‍

Quarterly Specialized Care:

‍

• Cleaning and removing stains from carpets
• Stripping, sealing, and refinishing hard floors
• Deep cleaning of upholstery
• Cleaning the outside of windows

This methodical way of doing things is why commercial properties that hire professionals keep their value. You're not just paying for work; you're also paying for knowledge, tools, and a system that works.

What makes buildings in Los Angeles different from others

Taking care of property in Los Angeles County is different from taking care of buildings in other places. Our environment presents certain problems that need to be dealt with by professionals.

‍

The southern part of California Factor

‍

Problems with air quality: Los Angeles has some of the worst particulate pollution in the country. This means that filters need to be changed more often, dusting needs to be done more often, and air quality needs to be kept up, especially.

‍

Climate factors: The weather in coastal areas like Santa Monica and El Segundo makes mold and mildew problems different from other places. Professional services know about these microclimates and change their procedures as needed.

‍

Customers have high expectations: Because LA's commercial market is so competitive, tenants have options. Not only do buildings in West Hollywood and Pasadena compete on location and price, but they also compete on how good the environment is. The cleanliness of your building has a direct effect on tenant satisfaction surveys.

‍

Following the rules: California has tough rules about the environment and safety at work. Professional office cleaning services keep up with OSHA rules, Cal/OSHA rules, and local laws that amateur cleaners often don't follow.

‍

How to Rate Office Cleaning Services (What Really Matters)

Dozens of janitorial companies will try to sell you their services. They will all promise great service at prices that are fair. This is how to tell the good providers from the bad ones.

‍

The Things That Can't Be Changed

‍

• Insurance and bonding: Your janitorial service should have at least $2 million in liability insurance and workers' compensation insurance. Don't try to bargain on this; if an uninsured worker gets hurt on your property, you could be held responsible.
• Training and getting a license: Check to see if they have CIMS-GB (Cleaning Industry Management Standard - Green Building) certification. This shows that the business follows the best practices and environmental standards in its field.
• Systems for checking quality: How do they make sure the work is done? Time tracking with GPS? Inspections by the supervisor? Portals for clients? You need to be able to see what you're paying for.
• Owning specialized equipment: Companies that own their own equipment instead of renting it show that they are committed and financially stable. You want partners, not businesses that come and go.
• Screening and keeping employees: How often do they leave? How do they check out their workers? The safety of your building depends on who has the keys.

‍

Red Flags That Should Stop Negotiations

‍

• Prices that are much lower than those of competitors (you get what you pay for)
• Not being able to give current client references
• No written rules or guidelines for cleaning
• No procedures for responding to emergencies
• "One-size-fits-all" plans that don't take into account the needs of each building

‍

The Future of Office Janitorial Services

The business of cleaning is changing quickly. Innovation is speeding up because the global market is growing by 5.3% every year until 2032.

‍

Technology Integration

Modern office janitorial services now incorporate:

• IoT sensors: Monitoring soap dispensers, paper products, and high-traffic areas to optimize cleaning schedules
• Robotic floor care: Autonomous machines handle repetitive tasks while human technicians focus on detailed work
• Data analytics: Usage patterns inform cleaning frequency and resource allocation
• AI-powered scheduling: Optimizing team deployment based on building occupancy

‍

Health-Focused Protocols

Post-pandemic awareness hasn't faded—it's intensified. Commercial buildings now require:

• Enhanced disinfection protocols for high-risk areas
• Indoor air quality monitoring and improvement
• Pathogen-specific cleaning for flu, cold, and virus prevention
• Documented sanitization records for tenant assurance

‍

Making the Right Choice for Your Property

You have choices. You could keep going with the person who is cleaning your building right now. You could choose the person who bids the least. Or you could make a smart investment in professional office cleaning services that will protect your property and give you an edge over your competitors.

The choice seems obvious when you look at the data:

• By 2027, the janitorial services market will be worth $441.54 billion because building managers see how useful they are.
• Commercial applications make up 90.1% of market revenue because professionals know how to get a good return on investment.
• Cleaning companies offer janitorial services 79% of the time, but only a small number of them do it well.

Your building deserves better than "good enough." Your tenants expect better. And your investment requires better.

‍

Take Action: Protect Your Building Investment Today

Professional cleaning services for offices aren't just nice to have for high-end buildings; they're necessary for any business property that wants to stay competitive.

‍

Every day you put off updating your cleaning schedule is a day your building loses value, your tenants question whether they should renew their leases, and your position in the market gets weaker.

‍

Here is what you should do next: Hire a qualified janitorial service to do a full inspection of your building. This isn't a sales pitch; it's a real look at what your property needs, what it's getting now, and how much the gap is costing you.
