Over the past 120 years we have grown to become one of the largest mechanical contractors in the United States. With annual sales exceeding $100 million, Danforth has the financial strength and stability to continue meeting the needs of our customers for many years to come. Our mission is to be the premier provider of mechanical services. We advise our clients in making the best decisions and we will maximize their successes in the execution of their decisions.

While the majority of projects that we have worked on have been in the Upstate New York and Northwestern Pennsylvania areas, we have been involved in major projects throughout the Eastern United States in recent years including Tennessee, Ohio, Rhode Island, New York, and Pennsylvania.

Our permanent staff consists of 100 experts in their line backed by an IBM System 400 computer and several Quick-Pens together used for estimating, cost control, and accounting functions. Our Project Management methods, evolving from many years of experience, leave nothing to chance. The Purchasing Division is most responsive to the needs of the field personnel, while at the same time being cost conscious. Our purchasing division’s ability to get needed material on site at the correct time and within pricing limitation is unmatched.

Our work force on jobs utilizes 250 to 500 tradesmen, most of which have been on our payroll for many years. Included are a substantial number of qualified general foremen.
