What Affects Foundation Repair Costs in South Carolina?
South Carolina's diverse soil conditions create distinct foundation challenges across the state, with the Upstate around Greenville and Spartanburg featuring the same expansive red clay that plagues neighboring Georgia and North Carolina, causing differential settlement in slab foundations. The Lowcountry region around Charleston has sandy soils with extremely high water tables that allow moisture to constantly saturate soil beneath foundations, leading to settlement and erosion. Hurricane seasons bring storm surge and flooding that can wash away supporting soils beneath coastal foundations, requiring emergency piering and stabilization. Most South Carolina homes are built on slab-on-grade or pier-and-beam foundations, with mudjacking, helical piers, and crawl space jack installation being the most common repair services. Labor costs remain affordable, keeping foundation repair below the national average.
