What Problems Do We Fix in Wilmington?
Foundation Settlement
When part of your home drops because the soil beneath it has moved or compressed, the symptoms show up as cracks, sticking doors, and uneven floors.
What this looks likeSagging Floors
In most Carolinas homes, the cause of a floor that sags or feels bouncy is wood rot or weakened joists in a damp crawl space underneath.
What this looks likeUneven Concrete Slabs
When a driveway, patio, walkway, or garage floor sits uneven, the soil under it has usually moved.

What Soil Is Wilmington Built On?
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 ground under the footings stays steady from season to season.
- FoundationsSoil that stays wet can stay soft under a footing, and water moving through sand can carry soil out from under it. Look for a settling foundation and a sinking foundation. See foundation repair.
- Crawl spacesWater close to the surface can mean standing water and damp air in a crawl space for much of the year. Look for moisture in the crawl space and sagging floors. See crawl space repair and crawl space encapsulation.
- Floor framingWater close to the surface keeps the air under a house humid, and joists and beams that stay damp can rot and weaken. Look for broken or cracked joists, and sagging floor joists. See framing repair.
- ConcreteSlabs on ground that stays wet can settle unevenly, and water running under a slab can wash sand out from beneath it. Look for a cracked garage floor, and broken or sunken sidewalks. See concrete leveling.
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.

What Do Wilmington Homeowners Say?
Had the chance to meet Corey and Amber with HydroHelp911, and they were both great to talk with. Corey is friendly, knowledgeable, and has that genuine NC small-town feel, where you know he really cares about helping people. In Wilmington, humidity often leads to crawl space moisture and foundation issues, which are common problems in the area. It’s reassuring to have experienced professionals nearby who specialize in crawl space repair, encapsulation, and foundation repair. I recommend HydroHelp911 to other homeowners in the area.
