Quality workmanship completed by experienced and dedicated employees has established Alterman as one of the top leading electrical contractors in Texas. Superior installations, completed on time, provide our clients with lasting results that minimize life-cycle costs. Alterman’s success can be attributed to the professional attitudes and exceptional skills and expertise of our managers, supervisors, electricians, technicians and support personnel.
Our corporate office is located in the city of San Antonio where we have been serving commercial and industrial clients since 1923. Alterman currently has expanded into Austin through the acquisition of Hill Electric, which has provided quality workmanship and cost-effective service to the city of Austin and surrounding areas since 1968.
Today, our capabilities include not only electrical construction and pre-construction management but also design and installation of voice and data communications systems, video cabling, access controls, security and surveillance systems, electrical service, preventive maintenance and 24-hour emergency service.
