Who we are


A-1 Concrete Leveling, Inc.

History of A1 Concrete Leveling

A-1 Concrete Leveling has grown from a small independent start-up to become America’s Largest Concrete Leveler.

Our patented technology and proven system have benefited not only from the expertise of Grover Miller, but also from the comments and suggestions offered by franchises of the system since 1992.

As a result of our continuing search and development, A-1 has expanded its focus, offering structural repair and reinforcement, chimney realignment, and straightening of bowed walls in addition to the concrete leveling work which is the foundation of our success.
