Excavation Contractor backed by 12+ years of local experience

Cronin Contracting, LLC started in 2014 with a clear focus: trucking and contracting work right here in Siouxland. We built the business from the ground up, taking on the jobs that required real skill, reliable equipment, and crews who showed up ready to work. That foundation shaped everything we do today.

Over the years, we grew into a licensed and bonded underground utility contractor. That growth wasn't accidental. It came from doing the work well, earning repeat calls from homeowners and commercial clients, and expanding our crew's capabilities to meet more of what the region needs. Today we run multiple crews handling a wide range of services across the tri-state area.

Our services cover a lot of ground, literally. We handle landscape and hardscape design, excavation, dirtwork and finish grade, concrete flat work, and epoxy flooring. We install and repair septic systems, remove trees, and take care of lawncare for residential clients. For commercial properties, we provide year-round lawn maintenance and snow removal so your site stays clean and safe no matter the season.

We serve communities across a wide stretch of the Siouxland region, including Sioux City, LeMars, and Hinton in Iowa; North Sioux City, Jefferson, Vermillion, and Yankton in South Dakota; and South Sioux City and Dakota City in Nebraska. Whether you're a homeowner in LeMars needing a new septic install or a commercial property manager in Sioux City looking for reliable snow removal, we have a crew that can get there and get it done.

We're family owned and operated, and that's not just a tagline. It means you talk to people who care about the outcome, not just the invoice. We're active in our community, and we take pride in the work we leave behind because we live and work in the same towns you do.

Ready to get started? Call us at (712) 490-1108 or email Andrew@cronincontracting.net. We're available Monday through Saturday, 7am to 7pm, and we'd be glad to talk through your project.
