"I am updating my rating for CA Electrical (Unfortunately Angi will not allow me to edit, so I am posting this as a new review). After posting my original review I was contacted by CA Electrical. The supervisor assured me that my experience was not their normal practice and that they normally made sure to call if there was a change of plans. I felt that they were earnest in trying to make things right, so I agreed to give them another chance. I ultimately decided to select them for my project to replace sub panel and install outlets. The crew was excellent and professional. They showed up on time, were professional and friendly, took extra care to ensure work spaces were left clean. Their workmanship was excellent and they did a great job of cleaning up some messy electrical wiring that had been there before. As an electrical engineer, I also appreciated the crews knowledge of code and ability to explain the technical side of the installation. I would use them again."

"Single Line Electric came to my house to view my need. 2 other companies I called wanted me to send a video of my home showing them my yard from the electrical box to my pool. They obviously didn't want the job. Nery came out and did a thorough assessment of my needs. His quote was reasonable and the project began soon after. I am very pleased with with Single Line Electric"

"Iâ m very pleased with the work Raja did to install my Tesla wall connector. He was very patient and responsive while was in contact with him through text. When he arrived for the installation, he explained the process in details and took time to clear any concerns or questions I had. His work was very clean and professional. The job was completed within the promised time. After the installation, he gave a thorough explanation about the connector. I would absolutely recommend Raja to my friends and I plan to contact him for any other electric work."
