Corporate History

It all began in 1907 when Morris Korn, equipped with a sponge and pail, started the Rutherford Window Cleaning Company. He quickly began to build a clientele and a solid reputation with his quality service.

In 1950, Morris Korn’s son, Herman, joined his father in the business. Herman expanded Rutherford Window Cleaning into a full-service commercial cleaning company. In 1973, Herman’s son, David Korn brought his new vision into the company, rebranding as Delta Building Services Corporation, a full-service building services organization. David, along with the topnotch team members that he has put in place, has transitioned Delta into a dominant force in the industry, providing services to various industries, serving the tri-state area and beyond.
