John Anthony Mahar Jr. Electrician works out of Wareham, on Massachusetts' South Coast, handling the kind of small residential electrical jobs a homeowner calls in when something needs fixing now — a ceiling fan, a bathroom exhaust fan, a panel upgrade, a bad outlet. Every review on file, five of them posted on HomeAdvisor and mirrored on Angi over July and August 2026, rates the work 5 stars, and the details line up across them: customers mention getting a text with an ETA before John arrived, being seen within a few days of calling, and having the actual problem — not just an estimate — handled on the spot. One reviewer said he installed a ceiling fan with a light faster than expected; another called the price fair and said they'd already referred a neighbor. HomeAdvisor and Angi both carry an Approved badge and list a trade license, number 62798, expiring July 2028 — that's the directories' own record rather than a state verification, so it's worth confirming directly. The review history itself is still short: five ratings show a consistent pattern of promptness and follow-through, but it isn't yet a long track record. For a straightforward electrical fix — fans, panels, outlets — the early reviews point to someone who shows up when he says he will and finishes in one visit.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from John Anthony Mahar Jr. Electrician. Use it to sanity-check bids, then get the real number in writing.
Standard receptacle swaps — a new dedicated circuit is a bigger job ($350–$750).
Flush mounts, pendants, chandeliers — hung on existing boxes.
Estimated range
$530 – $1,100
Typical electrical project around $820
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.
Came within 3 days fixed all the requested items
Very friendly and professional. Explain the problem and how it needed to be resolved. I appreciate his work.
John showed up on time to look at our job we expected he was going to give us an estimate but he showed ready to deal with our problems and took care of them straight away. I'd highly recommend John if you have electrical work
John got everything we needed done quickly and for a very fair cost. Would hire him again in the future when needed
