Keith Casida, the owner of K-CO Electric, instills confidence as soon as you meet him, and he doesn’t disappoint! He, along with staff member Tony installed underground wiring between my house and garage, all the while responding quickly because of the approaching winter and also adhering to the existing code that it had to be buried almost 2 feet deep. Besides being a more experienced electrician willing to take on more difficult jobs, he is a friendly guy that you will enjoy working with. I would definitely recommend Keith and K-CO Electric to anyone!

Suspecting that I needed a new electrical panel, I found K-CO through the BBB. Keith responded promptly to my inquiry and was great to work with. He and his team were knowledgeable, friendly and professional. This was a big job, and Keith took care of coordinating with the power company, pulling the necessary permit, and managing the City inspection. Would definitely use K-CO again, and happily recommend this company to others!

I had wire issues on the outside of my house, so Keith came out and explained all my options with fair pricing. I decided it was best to just upgrade my service now. Keith and his team were professional and did a great job. The whole process went quickly and smoothly thanks to Keith. Highly recommend.

I was interested in putting under the cabinet lighting in our old house. I didn't even know where to start. I Googled electricians in my area and found a few but they were not able to come out for a few days. One was able to come out but gave me an extremely high quote. Then I called K-Co and Sandy answered the phone. She was so pleasant to talk to and told me Keith would be calling me back. Keith did in fact call me back within a very short time. He told me he was about 10 minutes away and ask if he could come out to discuss the project. Who does that! He was professional, kind and went through every detail of the projected. Even showing me pictures, to ease my nervous mind about what the lighting would look like in my house. I quickly decided that K-Co would be the company I would use to install the lighting.
Keith and Jim showed up on time. They worked together very well and cleaned up afterwards. What a wonderful experience this whole project was from beginning to end and the lighting is absolutely beautiful! I would highly recommend K-Co Electrical, you will not be disappointed.
