How our group of companies developed

 

It was the late 1800s. New York City required that all buildings higher than six stories be equipped with a rooftop water tower. Barrel maker William Dalton saw this as a natural opportunity to expand his business. In 1894 he hired Polish immigrant Harris Rosenwach. When Dalton died two years later, his widow sold Rosenwach Dalton's lumber, tools and goodwill for $55. As other family members came to the US to join Harris, Rosenwach Tank Company was born.

 

Through the decades, the Rosenwach family shared a vision of expanding the company to a "one stop shop" for new water technologies, historic building preservation, outdoor site furnishings, and more. They knew that offering all services under one roof would eliminate the need for subcontractors while offering clients more cost efficiency. As Rosenwach developed new businesses, Herbert Rose Building Restoration, United Tower Maintenance, AMR Mechanical, Cool Water Technologies (CWT), Sitecraft and more were received with much success.

 

In 1995, the above companies became part of the umbrella entity of Rosenwach Group. Today, the Rosenwach Group continues to grow, adding new companies and services to the synergy.
