History

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. 

The 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.

In 1959, the company moved its operations to Bell Avenue in Des Moines, and two years later, expanded its capabilities by adding a piping division. Then in 1969, to honor its roots, the company changed its name to The Waldinger Corporation, and subsequently, TWC Services.

Since opening the first two service branches in 1987, TWC Services has grown to a network of 32 service branches with coverage across nine states including Florida, Georgia, Alabama, North Carolina, South Carolina, Tennessee, Arkansas, Kansas, and Texas. In 2023 we added our first branch in Houston, Texas, before further expanding our footprint in the state with the addition of our Canyon Lake branch. With these two acquisitions we are now able to serve major Texas Markets like Houston, San Antonio, and Austin.

As of 2024 our team has grown to over 4,000 professionals, of which 2,900 are trade, and achieved over $1 billion in annual revenue.
