We used Cook Electric when we lived in Placerville, CA. The company conducted projects efficiently. However, when we moved to Sacramento, we asked them to assess the electrical needs of our new home. The assessment was completed and had subsequently used Cook Electrical to install new wiring of our main "box". They also installed LED lighting in our kitchen. They were reliable and efficient but expensive. I've had no prior experience to estimate the charges. I suppose the distance between Placerville and Sacramento made a difference in Cooks reluctance to help us in Sacramento.
