We invite you to read some of what our customers have to say about Block Electric on our Testimonials Page. >>






Two brothers, Frank and John Block founded Block Electric Company in 1920. The company was started as an electrical contracting company serving Northern Illinois. Our small family business grew steadily though its first three decades and was incorporated in 1948.

Initially, we specialized in commercial and institutional (hospital) projects in the Chicago area. In recent years we have recognized a large part of our dramatic growth was from industrial accounts. We made a strategic decision to pursue this rapidly growing industrial market while still maintaining our valued commercial and institutional clients.

Because of our size and our distinguished customer base, the company is recognized as one of the largest electrical contractors in the Chicagoland area. We are, in fact, in the top ten percent in the country.

We embrace growth and progress and envision continued success through team building and encouraging our company, partners and clients to expect, and deliver, nothing short of excellent work.
