About Us

H.B. Frazer Company was founded in Philadelphia in 1906, which makes us the oldest electrical contractor in the Philadelphia area. We are now in our fourth generation. We specialize in commercial, institutional, industrial, utility line, and communications work, employing over two hundred tradesmen. Our office staff consists of over 40 men and women who are responsible for the estimating, engineering, accounting, transportation, and management functions of the business. We believe that the quality of the work is more important than the quantity and as a result have limited our coverage area to the Delaware Valley and southeastern Pennsylvania. Over the last three years our annual volume has grown to over $60 million. We have always taken pride in our ability to manage projects, especially with regard to cost control and scheduling. In addition, we have in-house graduate and professional engineers to provide any technical support that may be required.
