Crawl Space Repair in Wilmington
What Keeps Wilmington Crawl Spaces Damp?
Near the coast, a high water table and saturated sandy soil can keep the ground under a Wilmington home wet for long stretches, and NOAA 1991 to 2020 climate normals put Wilmington International Airport at about 60.2 inches of precipitation a year. Wet ground gives off moisture vapor, which is one of four sources we check, along with humid outdoor air, condensation and water that drains in. Wilmington crawl space inspections are free and are scheduled from our Metro Circle office.

How Old Is the Framing Under Wilmington Homes?
Based on U.S. Census Bureau survey data, the median Wilmington home was built in 1987, and about 40 percent of all 59,406 housing units counted, apartments and attached homes included, were built before 1980. More of them went up in the 1990s than in any other decade, 9,756 homes.
Under a home built in 1987, the original posts, beams and joists have carried the floor for about 39 years.
| Built | Homes | Share |
|---|---|---|
| Before 1940 | 5,506 | 9% |
| 1940s | 3,476 | 6% |
| 1950s | 3,978 | 7% |
| 1960s | 4,078 | 7% |

The ground in Wilmington
How Does Wilmington Soil Affect Crawl Spaces?
The most common soil in the USDA sample inside Wilmington is Seagate, a deep sandy soil over light gray clay loam. The USDA sampled five points inside Wilmington: two are Seagate, one is Leon, one is Baymeade and one is Lynn Haven. The wider county survey for New Hanover County leads with Murville, at more than a tenth of the land, then Leon, Kureb and Bohicket. The USDA rates the sample inside Wilmington low for swelling and shrinking.
Seagate is a deep soil that formed from old marine deposits of the Coastal Plain, usually found on Coastal Plain terraces. It is sandy for about the top three feet, and under that is light gray clay loam. Loam is soil with a mix of sand, silt and clay. It drains somewhat slowly, and it can stay wet near the surface for part of the year. The USDA rates it low for swelling and shrinking, which means it changes size very little as it gets wet and dries out.
Leon is a deep soil that formed from old marine deposits of the Coastal Plain, usually found on low, flat ground. It is sand from the top layer down. It drains poorly to very poorly, and it can hold water at or near the surface for much of the year.
What It Means for Your Home
- What works in your favorSeagate changes size very little as it wets and dries, so the piers and footings under a crawl space sit on steady ground.
- What to watchWater stays close to the surface in this ground for much of the year, so a crawl space can see standing water and damp air, and that moisture can reach the wood framing above. Humid air under a house can lead to musty odors, mold and wood rot over time. Near the coast, a high water table and saturated ground add to it.
- Signs you might noticeLook for moisture in the crawl space, sagging floors, and groundwater seeping into 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 Wilmington, the survey maps Seagate, Leon and Baymeade series. USDA rates the soil low for swelling and shrinking (weighted linear extensibility 2.7 percent). Across New Hanover County, it maps Murville, Leon, Kureb and Bohicket series. Series descriptions: USDA NRCS Official Series Descriptions for Seagate and Leon.
Our approach
How Do We Approach Crawl Space Repair in Wilmington?

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