Client Testimonials

"We had a fantastic experience with Shaeffer Excavating installing our new septic system. From start to finish, they made the whole process incredibly smooth. They guided us through every step of getting our new septic permit, making what could have been a stressful process feel simple and manageable.

The crew showed up early and put in full days of hard work, never cutting corners. They truly took care of everything—no detail was overlooked. Their equipment was top-notch, and it was clear they knew exactly what they were doing. The job was done in an impressively short amount of time thanks to their skill and quality tools.

What stood out the most, though, was their honesty and professionalism. You can tell they take pride in their work and genuinely care about doing things right. As a bonus, they were great with our dogs and treated them like part of the team. Highly recommend Shaeffer Excavating—five stars all around."

"Schaefer Excavating was a life saver. Put in a new drain field for me after mine failed. He took care of everything from the county to putting my sprinkler system back together. Trevon said s a super hard working young man. If I could give him 6 stars I would. "
