Our Main office is in Chatham, New Jersey and our state certified Master Electricians and technicians cover a great deal of territory throughout the state.  Officially Chambon is open Monday through Friday from 8:00 am to 5:00 pm, but we are well aware that emergencies do not always happen conveniently during those hours.  That is why we are always available for emergency work 24 hours a day, 365 days a year.   Our response time is next to none!
