About Us


It was the late 1980’s in New York City. The corporate style was selling the “bigger is better” mentality; the family business was out and mergers, acquisitions, & consolidations were in. Joseph Collins was working in this industry, and saw things differently. He believed that the time was right for a new type of facilities services firm. Joe started that ifrm, put his name on it, and neverlookedback.Together with a team of his most trusted colleagues, he took his message to potential clients.

Collins Building Services, Inc. was founded in October of 1988 with the philosophy that has made the company successful: top quality service and a commitment to each customer’s individual needs.

From Day 1, Collins Building Services has believed in personally-provided quality. With this guiding vision, the firm quickly gained a reputation as the company where leadership was personally involved with each account. In fact, all levels of management can be found onsite on a regular basis, ensuring day to day operations are being performed above expected standards.

Collins Building Services is based in transparency of operations, working with clients to develop individual methods and strategies for each and every location, but we also believe in initiative. From cutting-edge janitorial equipment, to our proprietary online quality assurance programs, to our comprehensive green cleaning program, CBS teams are constantly seeking out the newest, most effective processes to serve our clients.

Today, Collins Building Services is one of the largest facilities management firms in the New York City metro area, serving many of the region’s premier building owners & managers, corporations, and institutions. With 3,000 employees and over 100 million square feet in our portfolio, you get more than just a facilities management solution. You get The CBS Advantage. We believe this will outlast any market trend.

Ask Joe Collins about his success, and he will still recount the principle that has made this company’s history –“Never forget where you come from, and always take care of those that got you here.”
