Electrical Construction

Diefenderfer has been serving the electrical needs of our customers for almost a century. We continue to work for small local businesses as well as the region’s largest institutions. In many instances, we have been with customers from their beginning and have served them through tremendous growth periods. Our experience allows us to bring state-of-the-art ideas and installations to all our customers, ensuring a high-quality, cost-efficient job.


  • Design Build Services: Our in house design team uses proven cost efficient methods, eliminating the need to compromise your design because of overdesign and budget restraints.

  • Plan Spec bidding: with each of our 15 estimators offering unique expertise, we are able to offer timely competitive pricing for any size project.

  • Value Engineering: We identify items in a design that might have alternative methods or materials and offer the associated savings to a customer without compromising the quality of the installation.

  • Time and Material: We work hand in hand with the customer with an open book relationship, tracking material and labor costs as it is spent on the project. We often give a maximum price associated with the project, where the customer only pays for services he uses and recognizes any savings for money spent under the quoted price.

  • Emergency Calls: With a fleet of 25 service trucks, we are prepared to respond to your needs 24 hours a day. We are able to draw from our in house expertise to address your specific problem in a timely fashion.
