Personalized Service and Expertise When working with Blacktop Service Company, you’ll get to know us and we’ll know you and your project. Y
By 1970, Blacktop Service acquired a small chip seal company and began chip sealing. The same year, we purchased our 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 Northwest Limestone, an existing quarry in Fort Dodge, Iowa, and expanded into limestone crushing, wet sand dredging and redi-mix concrete.

What Blacktop Service Company is registered to do
The State classifies Blacktop Service Company as highway/street and bridge construction. That classification comes from the registration itself, not from us — it describes the work the business registered to perform, and it is not an assessment of skill or a limit on what they may quote for.
