About Us

ESA, Inc. is located in Madison, WI.  While our primary project base is in Madison and surrounding areas we also service customers throughout the state.


Historically, ESA, Inc. completes anywhere from 250-350 projects throughout the course of a year, our current workload continues to reflect that trend.  The project sizes vary from under 1,000 sq. ft. to over 400,000 sq. ft.. Our ability to provide successful project completion requires exceptional project management, timely communication and as importantly, our field staff are involved in the construction process as early as possible.  This involvement process allows us to become familiar with the unique aspects of a project as well as providing an overall understanding of the design intent.  Direct communication with all related trades provides us with crucial information that enables us to effectively manage, schedule and perform our work in a timely and productive manner.  All procedures are done in accordance with the standards set by the National Environmental Balancing Bureau (NEBB).


ESA, Inc. takes full advantage of current technology to process information in a timely manner and communicate effectively.  ESA, Inc. is committed to staying abreast of and implementing new technologies to better serve our clients.
