Consistent, professional-grade cleaning for offices, corporate campuses, and commercial buildings across Nassau and Suffolk County — on your schedule, with no excuses.
A Clean Office Is a Productive Office — and a Competitive One.
Your office is often the first impression clients, partners, and prospective employees have of your business. A consistently clean, well-maintained workspace signals professionalism, attention to detail, and organizational discipline — the same qualities you want associated with your brand. Conversely, a dirty or inconsistently cleaned office sends the opposite message, whether you notice it or not.
At First Aid Cleaning Services LLC, we provide commercial office cleaning across Long Island that goes beyond surface-level. We clean what's visible and what isn't — the underside of workstation surfaces, the sides of filing cabinets, the grout lines in restroom floors, and the elevator buttons no one thinks to disinfect. Our teams are trained to treat your space like a facility that matters. Because it does.
We work with single-tenant professional offices, multi-suite buildings, corporate campuses, and commercial building management companies throughout Nassau County and Suffolk County. Whether you need daily cleaning, weekly maintenance, or a custom schedule aligned to your building's occupancy patterns, we build a program that works for you — and delivers it, every time.

Scheduling Options
We Work Around Your Business Hours.
Daily Cleaning
Ideal for high-traffic offices, buildings with multiple tenants, or any facility where maintaining a consistently clean appearance every day is non-negotiable. Daily service ensures your office is ready each morning — no matter what happened the day before.
Weekly or Bi-Weekly Maintenance
For smaller offices or lower-occupancy environments, weekly or bi-weekly cleaning provides a thorough reset on a predictable schedule. This option works well for professional offices with under 20 staff, suites within a larger commercial building, and offices that maintain light daily upkeep between professional cleanings.
After-Hours & Weekend Cleaning
We do not disrupt your operations. Most of our commercial office clients prefer after-hours cleaning — once your team has left for the evening — so the space is clean and ready when they return. Weekend cleaning is also available for facilities that prefer not to have cleaning staff on-site during business hours.
Custom & Event-Based Cleaning
Need cleaning before a client presentation, after an all-hands event, or following a renovation? We offer one-time and scheduled event-based cleaning services in addition to recurring programs. Just call us and tell us what you need.
