Company History: A Century of Family Service

The story began in 1913. Charles Fennig started his plumbing business in the basement of his father's funeral home at 5th and Lincoln in Milwaukee. For most of the 20th century, the shop was on Milwaukee's southside. In 1990, they moved to a West Allis location on 68th and Mitchell, with a home office in New Berlin, WI. Today, third-generation owner Louie Fennig runs the operation, maintaining the family's hands-on tradition.
