“I started working with DTE in 1980. From that point forward they have done all our excavation. Over the years, we have done many projects, some very difficult and interesting jobs that have required a lot of thought. They have treated me with the utmost respect and all work has been perfect every time. They have become not only a huge part of my construction team, but they are good trustable friends. I would recommend their service to anyone, they are very capable.”

Michael Tapani is a good listener with a focused mind. Looking back, for our money, we got what we needed and more. Instead of just fixing a problem, I know Tapani also created increased value that more than offset my costs. Every day my wife and children and I appreciate the increased beauty and usefulness of our home and our whole property.Doug Alexander, Homeowner

Working with DTE for the past 8-9 years has been a great experience. Their knowledge in dirt work is some of the best. They are prompt with service and ability to complete jobs on time.
