How Old Is the Framing Under Columbia Homes?
Based on U.S. Census Bureau survey data, the median Columbia home was built in 1977, and about 53 percent of all 58,910 housing units counted, apartments and attached homes included, were built before 1980. More of them went up in the 2000s than in any other decade, 8,736 homes.
Based on NOAA 1991 to 2020 climate normals for the Columbia weather station, about 14 miles away, the average July dew point near Columbia is about 70 degrees. Dew point is the temperature at which water condenses out of the air, so in a vented crawl space, July air can leave water on the posts, beams and joists that are cooler than about 70 degrees.
Under a home built in 1977, the original posts, beams and joists have carried the floor for about 49 years.

| 1940s | 5,329 | 9% |

The ground in Columbia
How Does Columbia Soil Affect Crawl Spaces?
The most common soil in the USDA sample inside Columbia is Pelion, a deep sandy soil over yellow sandy clay. Of the five points the USDA sampled inside Columbia, two are Pelion, one is Troup and one is Vaucluse. The fifth point falls on ground the survey does not name as a natural soil, such as urban land or water. Across Richland County as a whole, the most common soil is Nanford, covering about a tenth of the land, followed by Tawcaw, Lakeland and Georgeville. The USDA rates the sample inside Columbia low for swelling and shrinking.
Pelion is a deep soil that formed from old marine and river deposits of the Coastal Plain, usually found on Coastal Plain terraces. Its top layer is sand with a little silt and clay, and under that is yellow sandy clay. It drains a little slowly, so it can stay wet for short periods in a wet season. The USDA rates it low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
Troup is a deep soil that formed from old marine deposits of the Coastal Plain, usually found on ridges and hillsides. It is sandy for about the top four feet, and under that is yellowish red sandy clay loam. Loam is soil with a mix of sand, silt and clay. It drains quickly.
What It Means for Your Home
- What works in your favorPelion changes size very little as it wets and dries, so the piers and footings under a crawl space sit on steady ground.
- What to watchClay soaks up water slowly, so after long rains water can collect on a crawl space floor before it soaks in, and the damp ground keeps adding moisture to the air under the house. Humid air there can lead to musty odors, mold and wood rot over time.
- Signs you might noticeLook for deteriorating insulation, higher energy bills, and moisture in the crawl space.
- How we address itWhere water reaches the floor, an interior crawl space drainage system that carries it to a sump pump is part of the repair plan. For damp air, our usual recommendation is crawl space encapsulation with a dehumidifier, and where the wood has weakened, crawl space structural repair.
Soil survey: USDA NRCS Soil Data Access (SSURGO), sdmdataaccess.nrcs.usda.gov. Inside Columbia, the survey maps Pelion, Troup and Vaucluse series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 1.38 percent). Across Richland County, it maps Nanford, Tawcaw, Lakeland and Georgeville series.

Problem signs
What Are the Signs You May Need Crawl Space Repair in Columbia?

- Sagging FloorsA sagging floor has dropped below the framing around it, leaving a visible dip or a soft, bouncy feel underfoot.
- Groundwater SeepageGroundwater seepage is water entering the crawl space from the ground itself.
- Deteriorating InsulationDeteriorating insulation is crawl space insulation that has lost its ability to slow heat transfer, almost always because it has taken on moisture.
