Marshalltown Company is a privately held American manufacturer of construction tools and equipment used for archaeology, asphalt, concrete, drywall, EIFS, flooring, masonry, painting, plastering, stucco, tile, and wallpaper based in Marshalltown, Iowa.

[4][5][6] The origins of Marshalltown can be traced back to the American inventor and entrepreneur Dave Lennox.

[9] Mr. Lennox, having other interests, decided to forgo the opportunity and instead, in 1890, gave his apprentice, Jesse Williams, who ran a small machine shop, the charge of making the trowels.

Following World War II, new facilities were constructed and business remained strong[17] during the postwar period.

Marshalltown tools are shipped globally and are used in such countries as Canada, Mexico, Great Britain, Australia, New Zealand, South Africa, Italy, the Netherlands, and Saudi Arabia.
