[5.0 Google reviews](https://search.google.com/local/reviews?placeid=ChIJjUO3M0x2mgsRkmNF4TG_1UY) - Upfront pricing > “Fair price, great service, and excellent communication.” Anthony Lau - EV charger & new circuits > “Alex took the time to debug my panels and found I had plenty of amperage for my projects, when other electricians were trying to upsell me on more amps than I needed. He was also the only one ensuring we get a permit and do everything the right way.” Ivan Llanos - Same-day service > “TopTech Electrical was incredible. Alex was very responsive and came out same day.” Kristina Rocha - Panel safety > “Outstanding service. Alex pointed out a potential electrical safety hazard in our home, an old and potentially unsafe circuit breaker box. There was absolutely no pressure, nor any false up-selling. TopTech will be my number one for electrical repairs.” Sanford Weitzner - Breaker & kitchen lighting > “Alex took the time to explain the installation process and diagnose the problem with our broken outlet. Alex and the TopTech office were great about communicating and keeping me informed.” D Mark - Emergency repair > “Within 5 minutes we had a call back. He came out later that afternoon, same day. He worked hard for three to four hours in extreme heat and small spaces and was done by 4:30 for a very reasonable price. His professionalism was unmatched.” Tammie Piveronas, Livermore - Doorbell transformer > “He quickly diagnosed that the real problem was a faulty transformer. What impressed me most was the level of care he put into the work. He spent just as much attention cleaning up afterward as he did solving the electrical issues.” Steven Du - Recessed lighting > “They installed recessed lighting quickly and did an excellent job.” Tricha Mata - Returning customer > “Alex came out to us in Brentwood just a day and a half later and provided a thorough estimate with options. We scheduled the service for the literal day after. The estimate was very reasonable, fair, and just.” Paul Soper IV, Brentwood [Leave Google Review](https://search.google.com/local/writereview?placeid=ChIJjUO3M0x2mgsRkmNF4TG_1UY)[Leave a Yelp Review](https://www.yelp.com/biz/toptech-electrical-livermore) Emergency service ## No power?
