Their Tech Chris came out to service and clean my septic system. What ideal workmanship he demonstrated in the work he preformed, his impressive attitude, and a very professional and personable demeanor. I got to hand it to him, for the work he does everyday and still has a smile on his face and answered all my typical resident questions. He was very difinitively and explained how this system worked and how to extend the life of these components for my benefit. I can't recommend him enough.

This review is long overdue! Herr put in our mound system a year ago and I can not recommend them enough! We had an issue with our septic system this week but they were on it and got us back up and running in no time! Ive had extensive communication with Todd before and during the installation process and have had great communication with Kelly regarding our issue this week! All of the guys that have come to work on the septic have been awesome as well! Herr is the place to call if you need anything regarding your septic system done! Theyre the best!

We hired Herr to install a new holding tank on our property and they were very responsive and professional when it came to letting us know our options and what we should do. The cost was straight forward and there were no hidden fees later once the job was done. We ran into some abandoned utility lines and other things on our property once they started digging and they did a great job of calling in the power company to figure out what everything was. Highly recommend Herr for your septic/holding tank needs.
