About Kotze Construction

Kotze Construction Co. has been laying a foundation for Milwaukee for over 90 years, when George Kotze began offering general construction work to a blossoming Milwaukee. Since then, Kotze Construction has been providing quality construction services to the city and solving Milwaukee's toughest construction problems.

At Kotze, we are all about making sure your construction needs are met with enthusiasm and success. We provide an unparalleled commitment to our customers and that can be seen in our work and our history.

The size of Kotze does not reflect an inability to handle tough jobs. In fact it is the opposite. As a smaller firm, we have more control over our projects, and with that control comes an attention to detail and quality that can't be found anywhere else. Our commitment to your satisfaction lies in understanding a project's goals and challenges, and then applying our unique expertise to follow through.
