Hear From Our Clients



“Expertise & care”

Emily & Chad R.

We worked with Thoreson Excavating on the excavation, grading, foundation prep and utility services for a new cabin on the Oregon Coast. Even though our project was on the small side, Thoreson extended every professional courtesy to us. The company provided detailed cost estimates in advance of the project, communicated well throughout the course of the project, and executed the work with expertise and care. Troy Thoreson was easy to work with, and we valued the experience he brought to the table working in the area. Troy went above and beyond what we expected in order to inform neighbors about the work being done on the project, and was also very helpful in navigating existing utility locations in the street and coordinating with city agencies on the work to be done. Working with Thoreson was a great way to kick off our project, and allowed for the rest of the construction work to proceed smoothly! We had a great experience working with Thoreson Excavating and would highly recommend them to anyone looking for excavation work.


“Honest, knowledgeable, forthright and hardworking!”

Tom Misner

I have known Troy for 20+ years, he is honest, knowledgeable, forthright and hardworking! Troy is an artist with his machines and the best operator I have ever seen!


“An artist when it comes to excavating"

Peggy M.

After 20 years of watching him work on various jobs I have found Troy to be an artist when it comes to his excacavating. It is incredible how accurate he can be with his machines.
