Brad Krotzer

Meet the Owner, Brad Krotzer

Brad Krotzer, owner of Custom Septic, Inc., started installing septic systems with his father when he was 11 years old. In 1996, Brad founded his own septic inspection and installation company after attending classes at the University of Minnesota.

Brad is licensed and certified with the Minnesota Pollution Control Agency (MPCA). As a septic contractor, Brad has completed various projects in northern Minnesota, including septic installations in St. Michael and Buffalo, as well as septic design projects in Elk River.

Brad’s pledge is to provide his personal expertise and excellent service to each of his clients. He understands how important your home is and personally works on your septic system from start to finish. Brad takes pride in his work and encourages you to contact his references to confirm his dedication and the trust he has earned throughout Minnesota.

One of the things that sets custom septic apart from some of the other installers is that he (Brad) is one of the installers on the job. He is the one at the job doing the work–not like some septic installers that that have hired help and you never see them. Brad will be onsite working and running the project giving it his personal attention.
