When your home is older, you need to replace faulty wiring, or you're doing a major remodel, it's vital that you hire a licensed electrician to handle your rewiring project.

Ant and Mark did an excellent job servicing my home today. They came out to give an estimate on my issue with no power to my water heater. They found that the water heater breaker was tripping and not resetting. I provided the breaker and they replaced that for me but they noticed in the laundry room was missing a bushing and the grounding wasn’t up to par along with a loose box. They did a great job of letting me know the issues and provided options for me. I will be recommending to family and friends the great work they completed for me. I now have hot water ; and now a happy customer!

Frank arrived, assessed the situation, and gave me options for what I want completed. He explained all options and once I made the decision, he went to work like a Boss! He was pleasant to talk with and answered all questions completely. What I liked most, he enjoyed doing what he knows how to do. He deserves a bonus! Thank you Frank and staff for getting here as quick as you did to complete an urgent matter. You’re tops in my book. Mr. Sparky will be my first and only call when service is required. OUTSTANDING!

- Sam Small

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!

New update 11/7/25- I had Mister Sparky out again for new electrical tasks since my first review. Again very pleased and will continue to call them for my needs. This time I had Matthew and team and it was a big job and they were extremely professional and respectful (and did a great job) Original review: Very pleased- Art was my electrician and he was so kind and professional. He did a great job hanging a very big light fixture on a very tall ceiling.

- Victoria Rambo

Art was extremely knowledgeable and professional. He did a great job installing our new light and dimmer.My wife and I are both extremely happy with the results. I highly recommend Mr Sparky and if you are lucky maybe you will get Art.
