Kansas City Master Companies, Inc. is a construction firm based in Grandview, Missouri, with roots tracing to the founding of Master Mudjackers in 1985 by Joseph L. Frey, Sr. and his son, David L. Frey. The organization emerged from the development of a mudjacking system that enabled controlled lifting from inside a settled structure, distinguishing it from earlier approaches and positioning it as a specialized solution in foundation repair and concrete leveling. The company integrates multiple related services under a single umbrella, expanding from mudjacking to include a broader range of foundation-related products and solutions, and it established a significant presence in the Kansas City market early on, eventually growing into the largest combined services contractor in its field in the area at that time.

 Located in Grandview, the business operates within the construction industry, serving clients who require structural stabilization and concrete leveling. The firm’s history reflects a focus on practical, on-site repair methods and internal material management, enabling safer and cleaner lifting within affected structures. Over the years, the organization evolved from its initial operations in Overland Park and a central Grandview campus to become a multi-brand entity incorporating related service offerings under the Kansas City Master Companies name, signaling a broader service footprint in the regional market.
