In the Beginning

Blacktop Service Company is a family owned and operated heavy highway Construction Company headquartered in northcentral Iowa. Founded in 1967 by brothers, Frank and John Wagner, and cousin, Ed Redding, the company began humbly, operating primarily out of their pick-ups and homes. With just a handful of employees, they performed commercial and private asphalt paving in north central Iowa.





By 1970, Blacktop Service acquired a small chip seal company and began chip sealing. The same year, they purchased their first asphalt plant located near Algona, Iowa. In 1971, property was purchased in Humboldt and a shop and office was built, establishing a home base for the company. By 1976, the company purchased an existing quarry in Fort Dodge, Iowa, Northwest Limestone, and expanded into limestone crushing, wet sand dredging, and redi-mix concrete.


The second asphalt plant was acquired in 1985 in Humboldt, Iowa along with an expansion to Phoenix, Arizona. The company continued to experience growth and increased volumes but recognized greater potential in the asphalt market. In 1990, the redi-mix operations were divested and the Company began focusing solely on asphalt related operations. By 1995, a third asphalt plant was purchased and placed in southern Iowa. Three years later, the original Algona plant was deconstructed and replaced with a larger asphalt plant in Whittemore, Iowa. In 2001, a fourth asphalt plant was purchased and placed in Aurelia, Iowa. In 2008, the fifth asphalt plant, in Allison, Iowa, was purchased.



In 2009, the Arizona operations were closed and all resources were relocated to Iowa. Shortly thereafter, Steffes Construction, a chip seal company in eastern Iowa, was acquired to expand the company’s chip seal operations. Blacktop Service now works statewide performing asphalt paving, chip sealing, milling, crack filling, and base work. The company employs over 80 people and continues to be owned and operated by the Wagner family.
