Trusted local crews for concrete, excavation, and garage builds done right in and around New Underwood, SD.
Services
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.
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.
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.
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.
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.
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.
