Harry Waldinger, a 30-year-old Austrian tinsmith, founded our company as  Capital City Tin Shop in 1906. He immigrated to the United States four years before that, having to leave his wife and young children behind. By doing furnace repairs and spouting work, he soon saved enough money to bring his family to the United States. 

TWC Services Growth / 1940 Iowa Sheet Metal Contractors BuildingThe business continued as a small family operation, changing its name to Capital City Sheet Metal in 1928. When Harry Waldinger died in 1935 at age 59, the company had four employees, including his sons Mose and Joe Waldinger. Mose handled bidding, while his older brother Joe performed and managed the work. 

In 1940, the young Waldinger brothers made a bold decision that proved to be a turning point in the company’s history. Against the advice of their banker and bonding agent, they formed a partnership to bid on a job ten times larger than anything they had done before.

The new partnership, Iowa Sheet Metal Contractors, was the successful bidder on the $150,000 barracks project located at Fort Leonard Wood, Missouri. They completed seventeen similar jobs in the Midwest over the next five years, and Iowa Sheet Metal Contractors soon became one of the largest sheet metal companies in the United States.

In 1948, our company was the successful bidder on the Mutual Benefit Life building in Omaha, Nebraska. In order to get the job done efficiently, Iowa Sheet Metal Contractors purchased Skilman Sheet Metal and employed its 25 skilled workers. This new branch was named Nebraska Sheet Metal Contractors.
