MoldHelpUSAWhy mold is common in Wilmington
Wilmington International Airport averages about 60 inches of precipitation a year under NOAA's 1991–2020 normals, and August and September each bring more than 8 inches, right in hurricane season. Florence in 2018 showed the extreme: the airport recorded about 23 inches from the storm, floodwater cut the city off from the rest of the state for days, and 2018 ended as Wilmington's wettest year on record, according to the State Climate Office of North Carolina.
Homes that sat wet after a storm, with power out and no air conditioning, are where many Wilmington mold problems began. About 38% of the city's homes were built before 1980, according to the Census Bureau, including houses in the historic district and Carolina Heights with crawl spaces, original windows, and plaster. Coastal humidity keeps those crawl spaces damp in a normal summer, too.
The EPA's advice, to dry materials within a day or two, is hard to follow after a hurricane, which is why a moisture check afterward matters.

Mold services in Wilmington
What mold work costs in New Hanover County
| Service | Typical range |
|---|---|
| Mold inspection, national range | $300–$1,000 |
| Lab sample, per sample (national) | $50–$350 |
| Typical remediation job (national) | $1,100–$3,400 |
These are national figures from Angi and HomeGuide, since no Wilmington survey meets our standard. After a hurricane, jobs that include flood cuts and crawl space work cost more, and rebuilding is priced on its own. See the remediation cost guide.
North Carolina mold licensing: what to check
North Carolina does not license mold work, and the general contractor license only applies from $40,000, so after a storm, Wilmington homeowners do their own vetting. Crews arrive from out of town after big hurricanes; ask for liability insurance, local references, and a written scope before signing. Exterior repairs in the historic district may need city review. See the North Carolina page.
Will insurance cover it?
Florence taught Wilmington the difference between wind and water. Rain driven through a roof damaged by hurricane winds is usually a homeowners claim, often with a separate hurricane deductible and a mold limit. Water that rose from rivers, creeks, or surge is flood damage, covered only by a flood policy. Start drying right away and keep every fan, dehumidifier, and generator receipt. The state Department of Insurance can help if a hurricane claim stalls. See does insurance cover mold.
