Tom was great! Very kind, considerate, understanding, and made sure when he came in and out of my home that my cats didn’t get out! He admitted that he’s more used to doing Ring doorbells, but was very respectful when we explained why we didn’t want that. Thanks Tom!

Outstanding service. Jim was on time and explained the work and equipment choices. He was cheerful and left everything in order. Calls to the office were answered quickly and Renee was knowledgeable. Mr. Sparky is my new go to service.

- Carol Pertchik

Jim was assigned to replace an outlet which had a prong stuck in it and place a new plug on my wall AC unit. He came early with his own shoe covers and completed the job quickly. He was professional, tidy, had a pleasant demeanor, and patiently answered all of my questions. 10/10, would recommend Mr. Sparky!

I had the pleasure of working with Jim, from Mister Sparky, and I couldn’t be more impressed with his professionalism and expertise. From the moment he arrived, he was thorough, friendly, and incredibly knowledgeable, making even complex electrical issues easy to understand. Jim took the time to answer every question I had, ensuring I felt confident in his recommendations. He didn’t rush the job or take shortcuts—he carefully diagnosed my issue, provided clear and logical explanations, and offered practical solutions that made sense. His ability to break down difficult concepts into easy-to-follow advice was truly appreciated. If you’re looking for an honest, skilled, and customer-focused electrician, Jim is the one to call! Highly recommended. ⭐⭐⭐⭐⭐
