What homeowners are saying
Real reviews from real customers on Google.
“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!”
“Great service and communication. I emailed them for a quote. I got a quick response back. I needed a EV charger installed and some breaker change in my panels. The job was quick and everything looks good and professional. I would definitely recommend them.”
“Excellent service / top-notch job completion. Was on time and completed the necessary work in a professional manner. Was very polite and great to work with. Would absolutely recommend.”
“Okay, not only was he very personable but he really went out of his way to get to my house on the same day that I called him for work. Yes, it was something I messed up and he fixed it with a smile on his face. The end price was exceedingly fair and I would highly recommend Owen for any electrical work that you need, I know that I’ve found the guy I’m going to call when I need work done.”
“Owen installed roof heating cables for us, and did an exceptional job. We thoroughly recommend.”
