"Less than a year ago Leading Edge installed an electric car charging port installed in my garage. They showed up at the appointment time, did the work in just a couple of hours and I was pleased with everything. Earlier this week, the circuit for all the bathrooms in my house stopped working. After checking the circuit breaker, I eventually decided it might be a bad GFCI receptacle. I replaced the GFCI receptacle and it still didn't work. So I called Leading Edge. Michelle communicated her arrival date/time and after arriving, quickly got to work checking the main circuits. After less than 10 minutes, she determined I likely hooked up the new GFCI receptacle incorrectly. She switched the wires and everything started working. And she didn't charge me for her professional help. I would definitely hire Leading Edge for my future electrical work."

"I needed my panel upgraded to install an EV charger. Drew was easy to book and came to the house and explained what needed to be done. He installed the new outlet and was able to change out a light switch the same day. The price was reasonable and the job was completed in no time. We are remodeling and updating our house so I have used this company at least three times for all my electrical needs. Its nice to have a reliable electrician. "
