John Anthony Mahar Jr. Electrician is listed on Angi in Wareham, MA. On that profile, John describes himself as a licensed and insured journeyman electrician with 10 years of experience in the electrical industry, with work across residential, commercial and industrial sectors, and says he serves the south coast, south shore and Cape Cod areas. Angi and HomeAdvisor list licence number 62798. In a 2026 review, John was on time, texted an ETA while on his way, and installed a blade fan with a light, getting the job done in less time than anticipated. In another 2026 review, the customers expected John only to give an estimate, but he showed up ready to deal with their problems and took care of them straight away. A 2026 review says he came within 3 days and fixed all the requested items. Another says John got everything they needed done quickly and for a very fair cost, and a third says he explained the problem and how it needed to be resolved.

John was on time and texted me when he was on his way with an ETA. He was polite and efficient and got the job done in less time than anticipated. He installed a blade fan with a light.I would highly recommend using him as an electrician and have already referred him to a friend in my neighborhood.
