 Trustindex verifies that the original source of the review is Google. All of the electrical outlets in my kitchen stopped working overnight. I called Lewis Electric and someone came out the next day to look at it and it was fixed within the hour for less than $200. The guys were professional and neat, and they saved my day! Great experience all around!

 Trustindex verifies that the original source of the review is Google. I had 3 outlets go out in my little A  cemesto house over the weekend so no tv or internet and Monday was a new year holiday.  Lewis Electric came out this afternoon and spent several hours tracing & fixing the issue and fixed me up.  I wish I had gotten the guys name who came out because he was wonderful!
And I thought the price was very reasonable for the amount of time and work required.
I highly recommend them!
