Once we establish the connection, we can customize your new generator so it provides power only to the parts of your home or building that you want to have electricity in the event of a power outage.

I had a really good experience working with Richard Cummings, Jr., an electrician from Mister Sparky. He arrived early, was professional and personable, and took the time to explain what he was doing and why. He clearly walked me through the pricing, the recommended repairs, and which items were higher priority versus things that could wait, which I appreciated. Richard wasn’t pushy at all, answered my questions patiently, and made me feel comfortable and safe having the work done in my home. He completed the job efficiently, cleaned up afterward, and made sure everything was in good working order before leaving. Overall, the experience felt transparent and respectful, and I appreciated how clearly everything was explained from start to finish.

I can’t complain I lost power to my efficiency apartment on New Year’s Eve at night Mister sparky tech Frank Ramirez came out to look at the problem and of course my electricity was the original from when the home was built 1950. Frank Thoroughly explained the problems I was having. Frank, David and Jason took care of the problem. Keep in mind the reviews helped me to choose a Reliable company. I have no regrets yes a little costly but so worth it! Thank you guys you all did an amazing job and no mess to clean up afterwards. Frank did go above and beyond to make sure everything was done correctly. Photos from old to new and added.

Thank you Luciano for scheduling my mounting quote appointment promptly and efficiently. Kevin showed up and did an amazing job with the inspection he provided for our new home. Kevin was very knowledgeable and really seemed passionate about his work. I appreciate the great service!
Erica Williams-Simmons
Kevin was great!! Very informative and professional. I would highly recommend him to any family and friends. He would also be our go to electrician if any other issues were to arise at our home. We were very pleased with his work.

My experience with The Mister Sparky team was great. I had an urgent issue with my outdoor panel following an home inspection and Timothy was on scene a couple of hours later. He took diagnostics and made sure all my questions were answered. The second day Keith and Matthew arrived and worked together to resolve issues in both our house panels. They were both professional and responsive and took their time afterwards to review their work with me.
