Greenlion was founded with one simple goal: to provide dependable building services that clients can count on. We recognized that many contractors, property managers, and facility owners struggled to find companies that communicated well, showed up when promised, and consistently delivered quality work.

What started as a commercial cleaning company has grown into a full-service building maintenance and support company serving clients throughout New York City and Long Island.

Today, we provide post-construction cleaning, janitorial services, painting, flooring, pressure washing, and other building support services, allowing our clients to work with one trusted contractor instead of managing multiple vendors.

Whether we're supporting a new construction project, maintaining an occupied facility, or helping prepare a property for turnover, our commitment remains the same to do what we say, communicate every step of the way, and deliver quality workmanship on every project.

At Greenlion, we believe strong relationships are built through reliability, accountability, and consistently exceeding our clients' expectations.
