We were looking to replace our septic system, we contacted De Jong Excavation LLC/Makron Engineering. Mark who is a Professional Engineer explained, in full detail, the whole process, from the design, permit and installation of our septic system. Since we are in an environmentally sensitive area , this was important to us. After this conversation we knew immediately that this was the company we were going with. We also loved the convenience of dealing with one individual who took care of the whole project. He arrived as stated and immediately started the project, finished in a timely manner, landscaping included. We are pleased with his job and confident that he stands by his work. Thank you Mark De Jong. read more
