We’ve served hundreds of Nassau County properties. Here’s what sets us apart from other cleaning companies on Long Island.
We assign a dedicated team to your property so they can learn your exact preferences and standards.
Early mornings, evenings, and weekends available — we work around your business hours or family routine.
Every employee is background-checked and we carry full liability coverage for your peace of mind.
We know Mineola, Port Washington, the North Shore, and the business density of Nassau's commercial hubs inside and out.
We tried two other cleaning companies for our Garden City office and both were inconsistent. Casey's has been coming every week for over a year — the same crew, the same standard, and completely met our needs.
