Hanahan is a Berkeley County city of about 21,452 residents (ACS 2024 5-year estimate). Its median home was built in 1986, sixteen years older than the Berkeley County median of 2002. That means at least half of Hanahan's occupied homes were standing before Hurricane Hugo made landfall at Sullivan's Island in September 1989, and many have been through decades of Lowcountry summers, storms and repairs since.
Age matters for mold in specific ways. A house built in the mid-1980s may still have original ductwork, older windows and flashing, and plumbing that has been patched more than once. Past water damage that was painted over rather than dried and replaced can leave mold behind walls or under floors. If you are buying an older home, a disclosure of earlier leaks or flood repairs is worth asking about, and an inspection can be money well spent.
About 68.1% of Hanahan's 8,009 occupied homes are owner-occupied, so most residents will arrange and pay for any repairs themselves. Add the region's climate, with about 52.51 inches of rain a year and August humidity averaging 79% (NOAA normals and the SC State Climatology Office), and small leaks in an older house have plenty of help turning into mold.
Getting free quotes in Hanahan

In an older home, a remediation company will typically trace the moisture source first, then contain the area, remove damaged materials, and dry and clean what remains. If your home has a crawl space, ask whether the quote includes the subfloor, joists and vapor barrier, and whether a dehumidifier or encapsulation is being recommended and why.
South Carolina has no mold-specific license. Ask about training, certifications and insurance, and about the SC contractor license or registration for drywall, insulation or HVAC rebuild work; specialty registration is required above $500 under SC Code §40-59-20.

Learn moreHanahan mold FAQ
Are older Hanahan homes more likely to have mold?
Age alone does not cause mold, but it raises the odds of the moisture problems that do. Hanahan's median home was built in 1986, so many houses have aging roofs, windows, plumbing and ductwork, plus decades of past repairs. Any of those can let water in slowly. The fix is finding and stopping the moisture, then removing what grew.
I'm buying an older home in Hanahan. Should I get a mold inspection?
It can be worth it, especially if you notice a musty smell, stains, or signs of past water damage such as new paint on one ceiling patch. Ask the seller about previous leaks or flood repairs. Cost guides put a mold inspection at about $450–$800. The EPA notes that if mold is visible, sampling is usually unnecessary.
Should I encapsulate my crawl space or just remediate the mold?
They solve different problems. Remediation removes mold that is already there; encapsulation seals the crawl space to control future moisture. Cost guides put crawl space mold remediation at about $500–$2,000 and encapsulation at about $1,500–$15,000. Ask each company to explain why it recommends one, both, or neither for your house, and get that in writing.
Who do I contact about permits for repairs in Hanahan?
Hanahan is in Berkeley County. Mold cleanup has no state license in South Carolina, but drywall, insulation, HVAC and building work can require local permits and an SC contractor license or registration. Ask the company you hire who pulls the permit and which office handles your address. This is general information, not legal advice.
