What Our Customers Have to Say

"Would highly recommend Dave and the guys at Allied Septic. We rent all our potties from them and have had nothing but a good experience. Communication is great! Always on time with delivery/pick up and the potties are always clean."

Brian C.

Customer Testimonial

"I recently had the pleasure of working with Allied for the cleaning/pump of my septic system, and I can’t express enough how impressed I am with their service. As a first-time homeowner, (with bad experience from a different well known septic company) I was a bit anxious about the whole process, but the team at Allied made everything so easy and straightforward."
