The Diagnostic Guys are our go to for anything electrical. They have done great work updating our light fixtures, adding new lighting (indoor and outdoor) and adding outlets. They are always courteous, prompt and meticulous about the details. Couldn’t be happier with the services they’ve provided for us!

We couldn’t find the trip outlet to reset some of the upstairs outlets . Isaiah found it in the basement buried behind insulation. Our master bath shower had no light, so Isaiah installed a recessed light for it. The garage only had the one bulb, Isaiah installed two florescent light fixtures. All of the work the Diagnostic Guys do is reliable, on time and priced below their competitors. I will definitely use them again!
