We are Very happy with the work completed by Heidegger Earthworks. Very professional, work completed timely and within budget!!
Dwight's crew completed a buried cistern tank and 3 frost frees across my property ( well this summer I hope). They cleared areas for my view, created a road and pad at the end for my horse shelter, and dug perc holes.
We plan on using Dwight again for future work.

Heidegger Earthworks exceeded our expectations!
Dwight was nice enough to meet us at 2 different properties before we actually moved forward with purchasing one! He envisioned the potential of this property and we were sold on the possibilities. He got to work and made the vision come to life!
Communication is top notch. He keeps you informed of progress and price is accurate. When we decided to make changes and add additional work during the process he happily accommodated us! We love how it turned out!!!

Dwight and his team did an absolutely fabulous job on our project! Professional, timely, and creative, I am so grateful that we chose Heidegger Earthworks. My husband and I bought raw land and our project changed halfway through and Dwight was willing and able to pivot our project to achieve our lake home property goals. Highly recommend!

We are so grateful for Dwight and his team for helping us with our recent project. We had trenches dug for both power and water for a new backyard oasis.
The Heidegger crew had great communication, worked diligently to complete the job in a timely manor and cared for our whole property well as they moved the equipment around. We would absolutely hire them again for future excavation work.

Outstanding company to do business with. Heidegger Earthworks have everything they need to do a professional job. I have used them several times and will continue using them in the future. Dwight and his sons are on time, hardworking and ethical.
