When we did restoration work on the fragile stone foundation at the Conrad Mansion, we knew exactly who to call to make sure that difficult excavation went smoothly. Trent’s talents with his machinery and the incredible integrity shown on everything he has done for us makes it easy to recommend Trent for any type of excavation, utility, or site-work, or helical pier project you might have.
