How Old Is the Framing Under Asheville Homes?
Based on U.S. Census Bureau survey data, the median Asheville home was built in 1979, and about 51 percent of all 48,302 housing units counted, apartments and attached homes included, were built before 1980. More of them went up before 1940 than in any other decade, 8,603 homes.
Based on NOAA 1991 to 2020 climate normals for Asheville Regional Airport, about 10 miles away, the average July dew point near Asheville is about 65 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 65 degrees.
Under a home built in 1979, the original posts, beams and joists have carried the floor for about 47 years.
| Built | Homes | Share |
|---|---|---|
| Before 1940 | 8,603 | 18% |
| 1940s | 2,423 | 5% |
| 1950s | 3,961 | 8% |

The ground in Asheville
How Does Asheville Soil Affect Crawl Spaces?
The most common soil in the USDA sample inside Asheville is Tate, a deep yellowish brown clay loam. In a USDA sample of five points inside Asheville, two are Tate and one is Clifton. The other two points fall on ground the survey does not name as a natural soil, such as urban land or water. Across Buncombe County as a whole, the most common soil is Evard, covering more than a tenth of the land, followed by Clifton, Edneyville and Cowee. The USDA rates the sample inside Asheville low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
Tate is a deep soil that formed from soil and rock that moved down the slopes above, usually found at the foot of mountain slopes. Its top layer is loam, and under that is yellowish brown clay loam. Loam is soil with a mix of sand, silt and clay. It drains well.
Clifton is a deep soil that formed in place as darker rock rich in iron and magnesium beneath it weathered, usually found on ridges and hillsides. Its top layer is loam, and under that is red clay. It drains well.
What It Means for Your Home
- What works in your favorTate drains well, so rain usually soaks away instead of collecting on the crawl space floor.
- What to watchOn a hillside lot, rain running down from the uphill side collects against the house, so the ground there can stay wet even where the soil drains well, and that water can seep into a crawl space. With humid summer air through open vents, the air under the house can stay damp, which 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 Asheville, the survey maps Tate and Clifton series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 2.47 percent). Across Buncombe County, it maps Evard, Clifton, Edneyville and Cowee series. Series descriptions: USDA NRCS Official Series Descriptions for Tate and Clifton.

Problem signs
What Are the Signs You May Need Crawl Space Repair in Asheville?
- Moisture in Crawl SpaceMoisture in a crawl space is any sustained dampness in the air, on the framing, or on the ground beneath your home.
- 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.
- High Energy BillsHigh energy bills are often a comfort and efficiency symptom, and in a Carolinas home the crawl space is a common, overlooked source.

I couldn’t recommend them enough!!
