JW Lafrenier Sons

Company Overview

Septic system planning, setup, repairs, and support.

We offer systems tailored for tough sites.
J. W. LaFrenier Sons was founded in the 1930s. The company was created by my grandfather, father, and two uncles. In 1988, the family business was purchased by Len and Lynn LaFrenier.

As new technologies emerge in the on-site industry, we participate in training to provide solutions for current building codes.
Len has been part of J. W. LaFrenier Sons since his high school days. During his time at UW Marathon and UW Madison, he dedicated his summers and weekends to the family business.
When not working, Len loves scuba diving, hiking, taking photos, and exploring astronomy.
