It is with great confidence I would recomend Grabau Construction. On a recent project for the Boone County Hospital Foundation, a cohesive design was very important. Their commitment to a high quality outcome was apparent and they helped us to meet the financial, functional and aesthetic goals of the project.
— Sara Behn, Director of Boone County Hospital Foundation
We have utilized Grabau Construction for both outdoor and indoor projects, this includes our most recent project which was the complete renovation of our high school gym in the summer of 2012. The organization skills, attention to details, accurate timetable of the work project, and the over-all professional service for this project was outstanding. Eric Hammer and his talented crew were a pleasure to work with from start to finish.
— Larry Moklestad, Athletic Director of Boone High School
Throughout the project, Grabau's promptly returned phone calls, offered suggestions, and listened to my needs. It was great working with a company where you could deal with the person who could make the necessary decisions and make those decisions happen.

I am writing this letter to thank you for the wonderful job your company did this past year on the construction of the new James H. Andrew Railroad Museum & History Center at the Boone & Scenic Valley Railroad.

The whole experience from design to completion was handled very professionally and the construction was very good. The subcontractors were all very good to work with as was the project superintendent.

I would be happy to recommend your company to anyone.

Grabau's held many progress meetings, both on site and at their office. These meetings provided good communication between all, which led to great cooperation between the trades and the owners. The contractors were able to look back and see how important it was to have Grabau Construction orchestrate a project from start to finish.
— Gary Nystrom, Pritchard Brothers Heating and Plumbing
Grabau's always brings reliability and quality to the job.

During the winter of 2012, Grabau Construction performed a façade renovation of the Boone Police Department Façade. This façade renovation was the result of countless hours of effort  by Grabau Construction. This company was relentless in their efforts to produce a quality project for the city of Boone. Physical construction of the façade was only one component of the efforts put forth by Grabau Construction.

Earlier during the summer of 2012 the staff of Grabau Construction took time to learn about the Police Department Façade Project. They spoke with city staff in an effort to understand the needs of the city. This company understood the complexities of a city project yet they were consistently up to the challenge. Later that fall, Grabau staff created several plans for the façade renovation. The concepts were presented to the City Council whereby minor adjustments were requested. Knowing that pending weather could be an issue, Grabau Construction put our project on the fast-track. That rapid response continued during construction.

Thanks to Grabau Construction and their partners (including Tony Franklin), the project was substantially completed prior to the onset of severe weather. We now have a weather safe façade that is already creating a whirlwind of favorable comments from citizens and downtown business owners.

A tremendous “thank you” goes out to Grabau Construction and all of those subcontractors that helped make this project a success.

I strongly recommend Grabau Construction for both design and construction projects. I am also willing to answer any inquiries about their company and their abilities to perform satisfactorily.

— Luke Nelson, City Administrator and Clerk
Grabau Construction is great to work with.
