Client Testimonials
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."
