Every facility gets cleaned by someone. The question is whose payroll that person is on.
Some companies hire their own janitorial staff. Others bring in a commercial cleaning service. Both models can work, and both can fail. What separates them rarely shows up in a wage comparison: who covers a call-off, who checks the work, and who carries the risk when something goes wrong.
We covered the warning signs in Is It Time to Rethink In-House Cleaning? This post puts the two models next to each other so you can compare them on the points that affect your budget and your building.
In-House vs. Outsourced Cleaning at a Glance
| In-house cleaning staff | Commercial cleaning service | |
|---|---|---|
| Cost | Wages plus taxes, benefits, equipment, supplies, and overtime | One contracted monthly price |
| Call-offs and vacancies | Your team finds coverage or the work waits | Provider sends trained backup |
| Supervision | Falls to a facility or office manager | Provider’s managers inspect and report |
| Equipment and supplies | You buy, store, and repair | Included in the service |
| Injury and chemical risk | Your workers’ comp policy and your training records | Provider’s insurance and training program |
| Scaling up or down | Hire, cut hours, or lay off | Adjust the scope of work |
| Your time | Recruiting, scheduling, payroll, and reviews | One point of contact |
What In-House Cleaning Really Costs
The usual comparison sets an hourly wage against a contract price. That is not a fair comparison, because the wage is only part of what an employee costs.
Across private industry, benefits make up 30 percent of what employers spend on compensation, according to the U.S. Bureau of Labor Statistics. Your number may be higher or lower, but it is never zero.
To get a real in-house figure, add up everything the cleaning program touches in a year:
- Wages, including overtime during call-offs and vacancies
- Payroll taxes, workers’ compensation, benefits, and paid time off
- Recruiting, background checks, and onboarding for every replacement hire
- Equipment: vacuums, floor machines, carts, and the repairs that come with them
- Chemicals, liners, and other cleaning supplies
- Training time, including required safety training
- The hours a manager spends scheduling, supervising, and inspecting
Then compare that total to a quote. When you review the quote, ask what is included. Labor, supervision, equipment, and chemicals usually are.
An outsourced contract will not always be the lower number. It will be the more predictable one, and it moves most of the line items above off your books.
Coverage: What Happens When Someone Calls Off
This is where the two models differ most in daily practice.
An in-house team is usually small. One cleaner out sick can mean half the building goes untouched that night. A resignation can mean weeks of gaps while you post the job, interview, and train. In the meantime, the work lands on whoever is left, or on employees who were not hired to clean.
A commercial cleaning service spreads that risk across a larger workforce. At NSG, every account is backed by a Flex Team: experienced cleaners who are cross-trained and onboarded at your site before they are ever needed, at no added cost. When someone calls off, the replacement already knows your building and your standards. We go deeper on that model in how NSG hires and trains reliable cleaning teams.
One caution if you are comparing providers: ask who will actually be in your building. Some companies sell the contract and hand the work to another firm. That changes the accountability picture, which we explain in The Truth About Subcontracted Cleaning Services.
Oversight: Who Checks the Work
Cleaning quality does not usually fail all at once. It drifts. A restroom gets a quick pass instead of a full clean. Corners get skipped. Nobody notices until a tenant or a visitor does.
In most in-house setups, nobody’s job is to catch that drift. The cleaner reports to a facility manager or office manager who has a full workload and no time to walk the building every week. Cleaning gets attention when there is a complaint.
A good commercial cleaning service builds inspection into the job. At NSG that means:
- Job cards for each role, so the scope is written down and not left to memory
- Timekeeping that confirms the crew was on site for the contracted hours
- Inspections logged through web and mobile tools
- An operations manager who visits your site every week
The weekly visit matters most. It puts a manager in your building on a schedule, looking at the work and available to you in person. For more on why structure beats good intentions, see The System Behind Consistent Commercial Cleaning.
Liability and Compliance: Who Carries the Risk
When cleaners are your employees, you are their employer in every legal sense. Cleaning is physical work. A strained back from lifting or a fall on a wet floor becomes a claim on your workers’ compensation policy.
Chemical safety is yours as well. Under OSHA’s Hazard Communication Standard, employers must keep a safety data sheet for each hazardous chemical in use, label containers, maintain a written program, and train employees at initial assignment and whenever a new chemical hazard is introduced. Commercial cleaning chemicals usually fall under that standard, even when the cleaning staff is two people.
With a commercial cleaning service, the provider is the employer. Their workers’ compensation covers their people. Their training program and safety data sheets cover the products they bring into your building. Ask for a certificate of insurance before you sign, and confirm it is current each year.
Outsourcing does not remove every responsibility. You still own or manage the building and the conditions in it. But the employer obligations for the cleaning crew sit with the company that employs them.
The stakes rise in regulated settings. Healthcare is the clearest example, and we cover what to ask for in Medical Office Cleaning in Cincinnati: What to Look For.
When In-House Cleaning Still Makes Sense
Outsourcing is not the right answer for every building. Keeping cleaning in-house can work well when:
- The space is small and one reliable person can cover it
- You already have a facilities supervisor with time to manage and inspect the work
- The environment needs a full-time employee with site-specific clearances or specialized process knowledge
- You have a long-tenured cleaner and a real plan for the days they are out
If none of those describe your facility, or if they used to and no longer do, the comparison above usually favors a commercial cleaning service.
What to Ask Before You Outsource
Outsourcing only fixes the problems above if the provider is built to fix them. A few questions separate the companies that are from the ones that are not:
- Are the cleaners your employees, or do you subcontract?
- Who covers a call-off, and have they been trained in my building?
- How often will a manager be on site, and will I see inspection results?
- What exactly is in the monthly price, and what is billed separately?
- Can I see a current certificate of insurance?
- What does the first 30 days look like?
That last question matters more than most people expect. A rough handoff is the main reason facility managers put off a change.

The Bottom Line

In-house cleaning gives you direct control. It also gives you the hiring, the coverage gaps, the supervision, the equipment, and the risk. A commercial cleaning service takes those on for a set monthly price, provided you choose one with the staffing and oversight to deliver.
NSG has cleaned offices, medical facilities, schools, warehouses, and industrial sites across Greater Cincinnati, Northern Kentucky, and Dayton since 1988. We are locally owned, our cleaners are trained in your building, and an operations manager is on your site every week.
