About Mims & Son Custom Siteworks

Local. reliable. equipped for the job.

Mims & Son Custom Siteworks is a family-owned and operated excavation and land development company serving Saint George, Harleyville, Dorchester County, the Lowcountry, and surrounding South Carolina communities. We specialize in land clearing, site preparation, grading, excavation, driveway installation, and drainage solutions for residential, agricultural, recreational, and commercial properties.



As a local family business, we take personal pride in every project. Our reputation is built on doing the work the right way, communicating clearly, and treating every property as if it were our own. Whether you're preparing a homesite, improving hunting land, or developing a commercial site, we provide dependable solutions that help you move your project forward with confidence.

What We Do


We handle full-service site development from raw land to build-ready property. Our work is focused on practical solutions that improve usability, access, and long-term performance in Lowcountry conditions.


From small residential lots to large rural tracts, we tailor every project to the specific needs of your land and your goals.

Equipment, Experience & Efficiency


We are fully equipped with professional-grade machinery including a forestry mulcher, excavators, skid steer, dozer, roller and dump trucks, allowing us to complete projects efficiently and safely.


Having the right equipment matters—it allows us to clear land cleanly, grade accurately, move material efficiently, and solve drainage problems correctly the first time. In the Lowcountry, where heavy rain, soft soil, and fast regrowth are constant challenges, proper equipment and experience make the difference between a temporary fix and a long-term solution.


Local Knowledge You Can Rely On


We live and work in the same region we serve, which gives us a strong understanding of local soil conditions, drainage patterns, and property challenges common throughout the Lowcountry.


That local experience allows us to:


  • Anticipate drainage and erosion issues before they happen 


  • Design driveways and roads that hold up in wet conditions 


  • Clear and develop land without unnecessary damage to usable soil 


  • Recommend practical solutions based on real site conditions 


  • We take time to walk each property, understand your goals, and explain the best approach before work begins.

Built on Trust, Communication, and Hard Work

We believe good work speaks for itself. Our focus is simple: show up, do the job right, and leave every property better than we found it. Whether it’s a small driveway repair or a large-scale land clearing project, you can expect honest communication, reliable scheduling, and quality workmanship from start to finish. 


We're proud of the relationships we've built. Here's what our customers have to say.

James did an amazing job mapping, planning and cutting our future driveway. We cannot say enough good things about his work. Highly recommend!

Mims and Son Custom Sitework did an outstanding job for us on two different projects we had done at our house. The first job was resurrecting our old driveway and fixing a drainage issue we were having, the second project was extending our driveway, relocating our fence to accommodate the new pad that they built for our motorhome. They were efficient, showed up early and left late on both projects, we highly recommend James and his company.

This is the best sitework company I have used. James is about the most honest, fair and attention to detail minded guy I've met. Don't waste your time like I have getting estimates from the other company's. Mims and son has the best prices and without a doubt has done the best work I've had done.
