What People Are Saying

Very happy to recommend Jim to anyone with septic issues or just a scheduled clean-out. Very Professional and Knowledgeable service. Jim is the only one I will call in the future for septic needs

Steven P.

Highly recommend this company. I recently moved into a house with a septic system. I knew nothing about having a septic system until now. They explained everything to me in great detail (even drawing pictures) as to how the system works and how to take care of it. I will use this company in the future!

Juan G.

Working with A.J McDonald was a great experience. As a first time home owner with a septic, he answered all my questions with ease and professionalism. I would recommend using this company to anyone.

Kara R.

Jim McDonald is what I would call a personal professional. He was upfront and informative explaining the process and procedures that he was implementing with the services that he provided. He also pointed out keys to look for and how to remedy problems that could arise at a later time. He arrived on time and updated me with his ETA, he stayed until he knew I was satisfied with the job. I would recommend A.J. McDonald Co to everyone.

Richard H.
