I guess you can review just about everything on yelp. I found these guys on google and just by luck decided to give them a call to do some small electrical projects at my house in the South Hills. I was very happy happy with the service that I received from one of the electricians named Kevin. I was very impressed at this companies ease of scheduling an appointment about a week out in the future and when the day came I received a phone call before the electrician arrived and more important to me was that he showed up on time even a little bit early. I was happy by his attention to the detail of the room as it was an older room and he was modifying some of the existing circuits as well as adding one. He made certain that I was happy with the placement of the new light switches and the fixture on the exterior of my house before he had actually installed everything. I also was happy that he was able to accurately quote me on the project before it began and was in the ballpark figure once it was complete. Once the job was complete he left no trash of his behind which was much appreciated. I'm definitely going to have Kevin come on back and do some more work in the future. If you have a job large or small, mine was relatively small, I recommend you all give KnK a try!
