Crawl Space Repair in Charlotte
What Causes Crawl Space Moisture in Charlotte Homes?
Moisture in a crawl space typically comes from one or more sources: ground moisture vapor, outdoor humidity, condensation, or drainage intrusion. In Charlotte, NOAA 1991 to 2020 climate normals for Charlotte Douglas Airport put yearly precipitation at 43.6 inches and the average July dew point at about 68 degrees, so both the ground and the summer air can carry water under a home. We assess every one of these sources before recommending a repair, and Charlotte visits are scheduled out of our Matthews office.

How Old Is the Framing Under Charlotte Homes?
Based on U.S. Census Bureau survey data, the median Charlotte home was built in 1993, and about 30 percent of all 383,380 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, 82,503 homes.
Based on NOAA 1991 to 2020 climate normals for Charlotte Douglas Airport, about 7 miles away, the average July dew point near Charlotte is about 68 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 68 degrees.
Under a home built in 1993, the original posts, beams and joists have carried the floor for about 33 years.

| 1940s | 9,467 | 2% |

The ground in Charlotte
How Does Charlotte Soil Affect Crawl Spaces?
All five points the USDA sampled inside Charlotte are Cecil soil, a deep red clay. Across Mecklenburg County, Cecil covers more than a third of the land, with Wilkes, Enon and Monacan the next most common. The USDA rates the sample inside Charlotte low for swelling and shrinking.
Cecil is a deep soil that formed in place as pale rock such as granite and gneiss beneath it weathered, usually found on ridges and hillsides. Its top layer is sandy loam, and under that is red clay. Loam is soil with a mix of sand, silt and clay. It drains well, and the USDA rates it low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
What It Means for Your Home
- What works in your favorCecil drains well, so rain usually soaks away instead of collecting on the crawl space floor. It also changes size very little as it wets and dries, so the piers and footings under a crawl space sit on steady ground.
- What to watchEven soil that drains well can stay wet where roof runoff collects or the ground slopes toward the house, and that water can reach a crawl space floor. The ground under a house also gives off moisture, and with humid summer air through open vents, the air there can stay damp, which can lead to musty odors, mold and wood rot over time.
- Signs you might noticeLook for sagging floors, deteriorating insulation, and higher energy bills.
- 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 Charlotte, the survey maps Cecil series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 1.5 percent). Across Mecklenburg County, it maps Cecil, Wilkes, Enon and Monacan series. Series descriptions: USDA NRCS Official Series Descriptions for Cecil.

Problem signs
What Are the Signs You May Need Crawl Space Repair in Charlotte?
- 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.
