Our Vision

Over our 127 year history, Quasius has expanded from a company specializing in residential construction to include commercial, educational, government, municipal, healthcare, industrial, religious, and retail construction. Our craftsmanship can be seen throughout Wisconsin in buildings such as the Sheboygan Police Department, Village of Fredonia Fire Station, and Lakeshore Technical College amongst many others.

About
Our vision

Building from the ground up or remodeling from the top down, Quasius brings experience and expertise to the forefront of your project.

"I think we had the best masons and carpenters possible for the job; I think they did a fantastic job."
