"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."

"This was the first time I used D-Tech Systems. I needed an electrician to reinstall a chandelier. Daniel Malachowski (with D-Tech Systems) was polite, extremely efficient, very conscientious about keeping the work area clean, and did a professional job in a short timeframe. During that same visit, he was able to resolve a couple of other electrical items and showed me how I could fix a simple item myself. I will use D-Tech Systems in the future and would definitely recommend them and, in particular, Daniel M."

"They came in real quick and fixed everything for us. We had them install a toilet for us about a year ago too, and since they'd done such a good job, we hired them now to fix our situation."

"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."
