Recently obtained the Services of McGaha Electric Co in Knoxville, TN. I requested that some electrical work be done at my home. Last week they sent a Service Tech out to look over the problems that I mentioned, we scheduled a time for the Service Call for the repairs. About 1 week later, on the day that we scheduled the repair, Christian & Austin showed up to begin the repairs. They worked quickly and were able to make the repairs that I requested. The Lights and Electrical are working well. Thank you for the Quick, Affective and honest service.

I called for a quote to have a L2 EV charger installed and got an estimate. They scheduled me 2 weeks out. I called multiple times to ask questions about the install and they were always courteous. They called 30 minutes before they arrived at my home, got the install done quickly and came in at half of what they had estimated originally.

I have known the McGahas for years, and as a general contractor used them many times on my projects. Now in retirement I called on them to assist with our kitchen renovation. David, Drew, Tony and Mason did a fantastic job at listening and thoughtfully executing the necessary work. Trust is king when you need the expertise of a professional. Awesome job McGaha!
