Who We Are
Who We Are

Our expertly trained staff and excellent performance speak for themselves, attracting the attention of Fortune 500 companies, corporate offices, industrial facilities and homes across Long Island.

Established in 1992, Deluca Cleaning we still retain many of our original clients from our first year of operation—these 25 year relationships speak for themselves. Ask us for client references, including references from Fortune 500 companies. Approximately 70% of our business comes from repeat customers and referrals.

Deluca Cleaning maintains a staff of over 200 cleaning professionals and we are always ready to respond quickly to your needs. As one of the top-rated Long Island office cleaning services, we offer a wide range of comprehensive cleaning services that fit your budget. Our deep expertise across many areas means we are able to self-perform most of the services our clients need, rather than relying on subcontractors—and these savings get passed on to our customers.

We take great care and pride in listening to the needs and concerns of our customers. We understand that you require a cleaning company that can meet the particular needs of your establishment. From presenting a thoroughly clean business environment in lobbies, hallways, boardrooms, offices and reception areas, to disinfecting bathrooms, gathering and removing trash, and even ensuring that stairways and elevators are pristine, Deluca Cleaning does it all while exceeding your expectations.
