Who We Are

Wellnitz & Sarow Builders is a family business serving south-central Wisconsin and the surrounding counties. We've been building homes for our friends and neighbors for more than 30 years and would love to build your new home.

Our experience in the home-building trade is exemplified in quality homes we build. The ability to build consistently high-quality homes comes from our employees and subcontractors— some of the most skilled and creative in southern Wisconsin.

Tom Wellnitz
Tom began in the home building trade as a framer at the age of 13, later moved into sales and is now co-owner of Wellnitz & Sarow Builders. He's on the Board of Directors for the South Central Wisconsin Builders Association (SCWBA) and an active member. Tom is also on the Total Quality & Management Council, the Janesville, WI City Council and a licensed real estate broker.
Bob Sarow
Bob, who has been with us since 1977, is the other co-owner of Wellnitz & Sarow Builders and is also on the Board of Directors for the South Central Wisconsin Builders Association (SCWBA). In addition to being a licensed real estate broker and a Wisconsin certified building inspector, Bob was the 2002 President of SCWBA, the 2001 & 2003 SCWBA "Builder of the Year" and a member of the National Association of Home Builders (NAHB).
Employees & Subcontractors
Many of the skilled tradesmen (and women) with whom we work have been a part of our "extended family" for many years. These long-term relationships contribute to a greater efficiency and level of workmanship when building your home. If you would like more information on any of our subcontractors, please contact us for details.
