"CD Electric was fantastic. They added electrical outlets to the interior and exterior of my home and installed an exterior light. Chase was very thorough with the estimate he provided me and completed the job in the time he said it would take. I would definitely hire them again for any future jobs and I highly recommend them to anyone else."

"I had a great experience with them. Their bid was right in the middle where it should have been. The guy who showed up had estimated for 5-6 hours worth of work, and he ended up staying here for almost 9 hours, but they didn't charge me extra for it, and I was happy about that. He was able to run the wiring where I wanted it to run. There weren't all the cables showing and he was able to stick it through my wall, and that is why he ended up staying here for so long. I was really happy with the service. My biggest thing was that the guy stayed until the work was done, he didn't say he would come tomorrow even if it meant working overtime."

"We hired Bi-State Electric to run a 20 amp circuit from our house to our new garden shed. This required Scott to hand dig a trench about 25 feet long between the house and shed. He installed a small porch light on the shed and a ceiling fan/light inside with switches to operate both. He also installed a total of 5 outlets at various locations inside the shed. As an added service, Scott installed a Whole House Surge Protector to our electrical panel and provided a safety inspection of the panel at no additional cost above his quoted price. Once the work was completed, the County Inspector came out and gave his stamp of approval."
