Local Service Area Content

At Flint Construction LLC, we help homeowners and contractors in New Underwood, SD with concrete, excavation and dirt work, and garage builds done the right way. We know projects in this part of western South Dakota need solid planning, proper site prep, and workmanship that holds up through tough weather. That is where our experience matters.

We are a small crew of two, and that works in your favor. You get direct communication, honest answers, and on-site attention from people who actually do the work. Most estimates are handled by the owner, so when we come out to look at your project, you are getting real insight from someone with hands-on experience.

Proud to serve New Underwood property owners

New Underwood gives people room to build, improve, and invest in their property. Whether you are adding a new garage, replacing a worn concrete slab, or preparing a site for construction, we understand the practical needs that come with rural and small-town properties. Good access, good grading, and a strong foundation are not extras. They are the start of a job that lasts.

We work with residential customers throughout the region, and we also earn a lot of repeat business and contractor referrals. About 30% of our work comes from other contractors who trust us to do the job right. That says a lot about the standards we keep on every project.

Construction services we offer in New Underwood

Concrete is the core of our business, and it makes up about 90% of the work we do. We focus on quality from the ground up, including proper compaction, slab thickness, rebar, vapor barriers, and the right concrete mix for the application.

  • Concrete slabs and flatwork
  • Concrete driveways and driveway replacements
  • Garage floors and shop floors
  • Patios, walkways, and approaches
  • Concrete foundations
  • Excavation and dirt work
  • Site grading and site preparation
  • Pad prep and compaction
  • Garage builds

Why homeowners in New Underwood choose us

We built Flint Construction LLC on simple values: do not cut corners, communicate clearly, and stand behind the work. A lot of concrete problems start long before the pour. If the base is not prepped correctly or the slab is not built to the right thickness, the finished job may look good at first but fail early. We take the time to get those details right.

  • Owner-led estimates on most projects
  • Honest communication from start to finish
  • Strong focus on proper site prep and compaction
  • Correct reinforcement, vapor barriers, and mix selection
  • High-quality residential construction work
  • Trusted by homeowners and other contractors alike

Our growth reflects the trust customers put in us. We did about $350K in revenue last year and are on track for around $550K this year. For a small company, that kind of steady growth comes from doing reliable work and treating people right.

A practical approach to estimates and scheduling

We keep our estimating process straightforward. In most cases, the owner handles on-site estimates personally. That means you can ask questions, talk through options, and get clear feedback based on the actual site conditions. We believe that helps projects go smoother and helps customers feel more confident before work starts.

If you are planning a new concrete project, need excavation and dirt work, or want to build a garage in New Underwood, we would be glad to take a look. Call Flint Construction LLC at (605) 441-9561 to talk through your project and schedule an estimate.

Why Homeowners Recommend Flint Construction

See what people notice most—solid work, clear communication, and results that last.

We recently hired Wylie at Flint Construction to complete a stamped concrete patio and a driveway extension at our home, and we couldn't be happier with the results. Wylie was professional, reliable, and easy to work with throughout the entire process. His attention to detail and craftsmanship really show in the finished product. The stamped patio turned out beautiful and has completely transformed our outdoor space, while the driveway extension blends seamlessly with the existing driveway. The work was completed on time, the job site was kept clean, and the quality exceeded our expectations. I would highly recommend Wylie and Flint Construction to anyone looking for high-quality concrete work.

Wylie came out, looked at the old concrete I wanted replaced, gave me an fair estimate. Arrived, tore out old material, leveled, formed up new area. Poured, finished and it is wonderful to have a nice new larger pad. He cleaned up area. I even wrangled his dog Baxter footpeint seal of approval. Highly recommend very good price, great clean up.. Very accommodating & good to work with.
