What Our Clients Say

  • "Nate cleared some land and built a retaining wall on the west side of my house. He is the first person I've had to perform a project to this extent, and I wouldn't have anyone else in the future. He was easy to work with and did a great job. Nate is knowledgeable from his years of experience in the construction industry; he has great ideas and understands how to complete the project correctly and on time. He is efficient and a great communicator, and his work is outstanding. If you're looking for a reliable company, he is the first I would recommend."

    —Brian M., Homeowner

  • “Nate has worked many jobs as one of our company’s subcontractors. He is honest and hardworking, and he always gets the job done early or on time. He does the work of an entire crew by himself. He is professional, courteous, and very experienced with all aspects of site work, both commercial and residential. I have not witnessed a better operator than him. When he walks away from a site, it is always clean, and everything has been done correctly. I would highly recommend Nate’s company to anyone needing site development, infrastructure, or municipal work.”

    —Mike U., Elk Horn Land Development

  • “I have been in the construction industry for 48 years, and you learn to appreciate quality people. Nate is that guy. He did a site development project at my lake house, including grading, infiltration trenches, block walls, landscaping, paver pathways, a 360ft driveway, and a sewer grinder system. Nate was amazing from start to finish and nailed it. Even my neighbors hired him to complete a job after they saw he never stopped working. When I refer Nate, I know he will take care of the customer. I will only hire him for projects because of his professional conduct, work ethic, and industry experience.”

    —Carl B., Homeowner

  • “I worked with Nate on a commercial project and highly recommend him. His communication skills, outgoing personality, and positive attitude make him a pleasure to be around. If you’re looking for someone who is reliable, hardworking, and demonstrates meticulous attention to detail, Nate is your guy.”

    —Dave W., Miles Resources, LLC

  • “For years, we have worked with Nate on countless projects for clients, friends, and ourselves, ranging from new construction projects to small landscape work. He is honest, fair, and reliable. His transparent communication and fantastic problem-solving set him apart. I recommend Nate for any project, as he is a true craftsman at his work.”

    —Lauren M., Aloe Built
