Grease Trap Cleaning In Maryland.
76 Years In Maryland.

A.J. McDonald Sr. started cleaning septic tanks & grease traps in Baltimore MD in 1941. The Baltimore Yellow Pages created a listing for septic tank cleaning for my grandfather. We were the only one in the book for a while. This generated so much work that my Grandfather was literally giving work to the competition. Eventually they figured it out and now everyone is in the book.

A.J. McDonald Jr. took over the business in the 70’s. A.J. Jr. was at his daughter's wedding reception in the 80’s when a call came that one of our customer's tanks was overflowing. So imagine the customer's surprise when he saw my father get out of the septic truck in a full tuxedo. That customer realized then that we offer customer service like no one else! In the fall of 2010, A.J. Jr. retired and left the business to his two sons, Jim and Mike, who passed it down to 3rd and 4th generation owners Jim & son Jim McDonald. Because of determination to take care of our customers, we have operated for 76 years now without a single formal complaint ever filed against us.
