  • “Very satisfied. They replaced our entire circuit breaker box. Water was getting inside-dripping in from the electric meter outside. Could have been a catastrophe. The guys were very polite and professional.” -Andrew M. Cherry Hill, NJ


  • “Great work, professional and courteous!!!” -Juan M.” South Jersey


  • “Initially we asked Cobalt Electric, LLC to fix a ceiling fan and other minor lighting problems. However, upon reviewing our 30 year old electrical panel, they noticed that it was wired improperly, was not up to current code, and could result in an electrical fire. Cobalt suggested solutions which we followed; and now our family feels much safer. We would highly recommend Cobalt, without reservation, for any residential electrical work.” –Krista & Rick, South Jersey


  • “Joe is proficient with his knowledge as others I have referred do tell me they appreciate his consultations, as well as, his performance with “emergency services” when timelines count the most!” -Rebeecca S.
