A. Alessi

Mike at Hinds Septic was incredibly helpful, knowledgeable, and responsive when we learned our home may need a new septic system/leach field. He went above and beyond and provided sound advice / design services, as well as recommendations to other contractors we would need (septic inspector, installer) to make the process so much easier. He was also cost conscious reviewing options and I never felt like he was trying to sell us something we did not need.
Years ago my parents used Hind Septic to design a complicated new septic system/leach field for a lakefront home. My dad was a civil engineer and very knowledgeable about septic systems in his own right. He had high standards for a design team and Deb Hinds delivered. It was a pleasure to work with her son, Mike, more recently and I can not recommend them highly enough.

With little success finding a local firm to conduct septic-related services, I widened my search a few miles and found Hinds. They provided a level of professionalism I hadn’t seen in a while…like “answering the phone (and yes it was actually a real human)” and then “answered my questions (that’s when I could easily tell they were extremely experienced and knowledgeable)” and then they actually “negotiated a workable schedule” in spite of how crazy busy they were, then “showed up/did the project/finished when they actually said they would.” Nice to see the Covid-lazy mentality hasn’t infected all businesses out there. Class act and real people. Two thumbs up from us. Shout out to Deb and Mike!
