The EC Difference

Nix Companies has a strong heritage that began in the late 1800’s when Charles Nix settled in Poseyville, Indiana. Charles operated a blacksmith shop shoeing horses and forming iron. At the conclusion of Charles’ career, his two eldest sons ran the business for several years before turning the business over to the youngest son Carl. Carl operated out of a small dirt floor building for several years before moving across town to its current location at 129 West Fletchall avenue in Poseyville. Carl and his only son, Carl Jr. (Sonny) constructed the building at its current location in 1957. This father and son team formed Carl A. Nix Welding Service, Inc. In 1975, the fourth-generation was added when Charles William Nix (Bill), son of Sonny, joined the team. The three worked together until Carl Sr. passed away in 1982. In recent years, the fifth-generation was added when Matthew Nix and Adam Nix, sons of Charles William, joined the family business. In the past decade our company has seen growth in various areas including new equipment, larger buildings and infrastructure, and a growing staff. These changes have come about to both adapt with the ages and meet the ever growing demand for our services. As we continue to adapt and grow there is much emphasis on remaining the same. We will always strive to meet the same level of quality and customer service set forth by the generations before us.

EC Buildings is part of the NIX family of businesses. Our fifth generation family business has been around over 115 years. This can be attributed to our humble and hardworking business practices, our quality craftsmanship, and above all, our commitment to integrity in both people and our products. Our staff is friendly, knowledgable, and easy to work with.
