What Commercial Office Cleaning Services Include
Every CNS office cleaning engagement is scoped during a walkthrough before the first crew arrives. The scope is built around your facility, your hours, and your standards.
Standard scope includes:
- Vacuuming and mopping all floor surfaces
- Dusting desks, shelves, light fixtures, and electronics
- Restroom cleaning, disinfection, and restocking
- Trash and recycling removal
- High-touch surface disinfection: door handles, elevator buttons, light switches, shared equipment, and keyboards
- Breakroom and kitchen cleaning
- Surface wipe-downs across all common areas
Frequency runs from five nights per week up to full seven-day coverage for facilities with round-the-clock operations. The walkthrough confirms the right schedule before the first crew arrives. If your needs change, one call to your account manager adjusts the scope.
Many office cleaning clients add commercial floor care, carpet cleaning, window cleaning, and upholstery cleaning to their program. For facilities that need daytime coverage, CNS also provides day porter services.
Why Facility Managers Switch to CNS
The complaint we hear most from managers who have tried other vendors: “The crew changes every time. Nobody knows the building.
The complaints we hear most often:
- The crew keeps changing. Nobody knows the building.
- Quality was great the first month. Then it slipped.
- I leave voicemails. Nobody calls back.
- We're locked in for two years and they know it.
CNS Cleaning Company was built to answer each of these directly.
The same cleaning team is assigned to your facility and stays there. No rotating pool. No strangers each week. Your crew knows where everything is, what gets inspected, and what your standards are.
We answer the phone live, 24 hours a day, 7 days a week, 365 days a year. Three rings or less. If there is an issue after a visit, call us. We fix it within 24 hours at no charge. That is the guarantee.
No long-term contracts. We keep your business through the quality of the work.
Each account also gets a named point of contact on our side. You are not calling a general line and hoping someone knows your building. Your contact knows your scope, your standards, and your schedule.

Frequently Asked Questions
How often should a commercial office be cleaned?
Most offices run well with nightly service five days a week. High-traffic facilities need six or seven-day coverage. This includes corporate lobbies, open floor plans with 50 or more employees, and medical offices. CNS scopes the right frequency during the walkthrough based on headcount, facility size, and traffic.
Does CNS send the same crew every visit?
Yes. CNS assigns a consistent crew to your facility. The same people show up each time. They know the layout, your inspection standards, and which areas need extra attention. This is one of the main differences between CNS and franchise cleaning companies, which rotate crews by availability.
Do we need to sign a long-term contract?
No. CNS runs on month-to-month agreements. If the service does not meet your standards, you are not locked in.
What happens if a visit does not meet our standards?
Call 215-985-1830. We answer live, 24 hours a day. Our 24-hour guarantee means we return and fix the issue at no charge. You do not pay for a problem we did not correct.
