Sparks Fly Between Us and Our Customers
We needed a ceiling fan added to a room and the chandelier from that room moved to our kitchen area. Nathan did an amazing job checking for safety and did a thorough diagnostic review and gave us a complete picture of the electrical health of our home. He gave us amazing recommendations which we will follow. Nathan’s customer service was so amazing he went above and beyond the call! He even wiped down the light fixture which hadn’t been done ever. He was very kind and professional. We very happy!

Read MoreI am very satisfied with my experience with Mister Sparky. I got to personally work with Caleb and he exceeded my expectations. We recently got an EV and needed to install an at home charger. He did a complete walkthrough of our home and gave several options. The install was exactly what I wanted and is working out great! Highly recommend this company. They are thorough, professional, personable, and not pushy like some of the other companies out there. Will definitely work with them in the future.
