“I had an excellent experience with Cornerstone Electrical installing the charger for my Ford Mustang Mach-E. The installation was done professionally, everything was neat and well organized, and the entire process was smooth from start to finish. The electrician was incredibly friendly, knowledgeable, and took the time to answer all of my questions. It’s clear they take pride in their work. I highly recommend Cornerstone Electrical to anyone looking for a reliable EV charger installation. Five stars all the way!”
