About Us

In 2007 Denny’s Electric & Motor Repair, Inc. began Directional Drilling, focusing primarily on underground Gas and Electric Utilities. 

Experience Matters

After years of experience, the directional drilling demand grew.  From the valuable feedback from our customers we continued to expand to meet the needs of our customers.  In 2017 the boring division was separated and Extreme Underground HDD, LLC was created as a unique and independent company. 

With the advent of more sophisticated equipment and software to provide even more accurate drills, Extreme Underground became one of the leaders in the field of Directional Drilling and is sought out by contractors, engineers and owners across the region. We continually upgrade our equipment and technology to provide the quality of service our customers have come to expect.

We have dedicated teams of employees that ensures we meet the customer’s expectations. We have years of experience installing Gas and Electric Utility Lines, Oil and Gas gathering Lines, Water Mains, Sanitary Sewer Lines, Force Mains and Storm Water Lines and Fiber Optic.
