About Primary Contractors
Founded in 2004 by William Boehm, Primary Contractors was built on a strong foundation of hard work, industry knowledge, and a commitment to getting the job done right. William began his career as a Journeyman Lineman with the local power company, gaining valuable experience in utility infrastructure, electrical systems, and field operations.

From excavation and septic installation to utility infrastructure, drainage systems, demolition, and site development, Primary Contractors has earned a reputation for finding a way to get the job done safely and efficiently.
The company is especially recognized throughout the region for pond construction, pond development, and ongoing pond maintenance. Whether building a new pond, restoring an existing one, improving drainage, or preparing a site for development, our team brings the knowledge, equipment, and experience needed to complete projects of all sizes.
