Why mold is common in Wilmington
Wilmington sits between the Cape Fear River and the Atlantic, and its summers are long and humid. Add a housing mix that includes homes dating to the 1700s and 1800s, and mold has many places to start. Homes in and around the historic district often sit on raised foundations over crawl spaces that were never designed with a modern vapor barrier. Mid-century neighborhoods like Forest Hills and Pine Valley have their own crawl spaces and aging ductwork. Newer homes and apartments are tighter, which helps with energy bills but traps moisture when bathroom fans or AC systems aren't doing their job.
Flooding adds to it. Florence cut off the city in 2018, and neighborhoods around Hewletts Creek, Burnt Mill Creek and Greenfield Lake see stormwater flooding during heavy rain. Any time water gets into a crawl space or lower walls, mold can follow within days.
Mold in historic and older homes
Older homes call for a careful approach. Original plaster and old-growth wood framing can often be cleaned and kept rather than torn out, as long as they're structurally sound and fully dried. Ask any crew how they plan to handle original materials, and whether they've worked in older homes before.
Homes built before 1978 may have lead-based paint. Under federal EPA rules, contractors who disturb painted surfaces in pre-1978 homes for pay generally must be certified in lead-safe work practices. If mold removal will involve cutting into painted walls or trim, ask the crew about lead-safe methods before work starts.
Where mold shows up in Wilmington homes
- Crawl spaces under older and mid-century homes, especially near creeks and low-lying streets
- Behind plaster and under old wood floors after roof or plumbing leaks
- Attics under storm-damaged roofs or where bath fans vent into the attic
- HVAC systems during the long cooling season
- Ground-floor storage and garages in areas that see tidal or stormwater flooding
- Apartments and student rentals, where small leaks may go unreported
After a flood or storm in Wilmington
If water got into your home during a storm, a king tide or a heavy rain event, start drying within 24 to 48 hours, which the EPA notes usually prevents mold growth. Floodwater from creeks, the river or storm surge is considered contaminated, so carpet, insulation and drywall it touches usually have to come out. Check your crawl space after any event that flooded your street, even if no water came inside.
How mold remediation works
A crew inspects the home, finds the moisture source and maps how far the mold has spread. The work area is sealed off with plastic sheeting and HEPA air filtration, moldy porous materials are removed, salvageable surfaces are cleaned, and everything is dried before repairs begin. Fixing the moisture source is part of the job, or the mold will return.
