Had a Generac generator issue, and they came out to solve the problem the next day. Fair price and great service.

D. K. Electric is timely, knowledgeable, fair, and honest. David treats us like family and Harry, and I would recommend them to all.

Ann Batagianis

The gentleman who helped connect our attic fan and set up a new outlet in our basement bathroom was wonderful! He worked quickly, but like a perfectionist!

Tisa Murrell

David did an excellent job on re-wiring my breaker box. He even made a new cover for it when I accidentally threw mine away. I would highly recommend!!

Larry Miller Door and Glass

Nate from D&K assembled and installed a pendant light on a 17 ft ceiling in our house. He was friendly, and professional, did the work in a timely fashion, and did a great job. I would definitely recommend this company for electrical needs.

Nancy Doughty

These guys are professional and not pushy. They will tell you the truth and options that will work. Courteous and friendly. They did a great job!
