James from Machesney Park, IL

Our experience with Black Diamond workers, Brian, Rich and Jason, and the Bore Cat crew was very positive! Good knowledgable people that listened to us and were easy to work with! The expense of the job was matched by the quality of the work and the finished product. We will recommend Black Diamond to friends and family.
