With an experienced and skilled workforce, we self-perform most of our work.

Ennis Electric owns a full complement of heavy equipment, tools and innovative technologies to deliver quality work efficiently and safely. With an experienced and skilled workforce, we self-perform most of our work. Our warehouse in Manassas, VA specializes in assembly prefabrication and logistics planning. By identifying prefabrication and staging solutions up front, we are able to meet challenging project schedules and logistics. Prefabricated assemblies are designed, built and packaged in our facility, empowering us to utilize LEAN manufacturing principles, which ensure materials are chosen carefully and assembled in a safe, controlled environment where the highest quality can be achieved.

Ennis Electric takes great pride in our quality assurance. Our company trains and educates our employees, subcontractors and suppliers to improve quality performance. We maintain quality control to ensure all elements of our work—including documentation, procurement, handling, fabrication, installation and testing—meet the project’s requirements.
