Reviews

Take a look at what your neighbors are saying about us.
  • I am an electrical contractor and I have hired Stone Fox for 2 projects so far. I had them cut a trench for me down the side of a steep hill and also had them do some skid steer auger work for me. It was obvious to me as soon as I saw the owner Morris start to operate his machine that he is an expert at what he does. Its amazing the difference in efficiency and precision between a novice excavator and an experienced company like this. I will be using them for all of my excavation needs.
