Crawl Space & Basement Waterproofing in Columbia, SC

Crawl space and basement waterproofing in Columbia, SC

Columbia is known for heat and humidity, and that humid air ends up under a lot of houses. Older neighborhoods like Shandon, Rosewood, Earlewood and Melrose Heights have many early-1900s and mid-century homes on vented crawl spaces, often with original brick piers and little moisture protection.

Moisture problems we see in Columbia homes

Columbia sits along the Fall Line, so soils change across the city, from clay in some areas to sandier ground in others. Clay areas hold water against foundations, while low-lying lots near creeks and rivers deal with high groundwater. In both cases the result in the crawl space looks the same: condensation, fungus growth and damp wood.
