Crawl space mold in Rex is removed by taking out wet or moldy insulation, cleaning the joists and subfloor, and fixing the moisture source under the house. Since Rex is unincorporated, related repair permits and code questions go to the county. Call the number on this page to be connected with a local mold remediation company in Rex.

Who handles permits for crawl space repairs in Rex?
Rex is an unincorporated community in eastern Clayton County, about 13 miles from Atlanta, centered on the historic Rex Mill village. It once had a town charter, but that was repealed in 1922, so building permits come from Clayton County Community & Economic Development at the P.K. Dixon Building in Jonesboro. Mold cleaning itself is not permit work. Replacing rotted joists, sill plates or subfloor is, and the company should tell you if your job crosses that line. If your Rex mailing address actually sits in Henry County, check with that county instead.
What makes Rex crawl spaces damp?
The usual south metro mix. Summers are long and humid, and air pulled in through foundation vents condenses on wood and ducts chilled by the air conditioning. Red clay soaks up storm water and releases it slowly. Clayton County was under a state of emergency during the September 2009 floods, a reminder of how much water heavy rain can push toward a foundation. Inside, the most common culprits are:
- A torn or absent vapor barrier over bare soil
- Gutters and downspouts emptying at the foundation
- Slow leaks from supply lines and drains
- An air conditioner condensate line ending under the house
How much should I budget?
Angi's Atlanta cost guide reports crawl space mold remediation at $587 to $2,348. HomeGuide's 2026 national range is $1,500 to $4,000, and Angi puts encapsulation from about $5,000. Square footage, crawl height, insulation removal and whether the moisture fix is included make the biggest difference. Ask each company to price the cleanup and the moisture work separately so you can see where the money goes. Georgia has no mold license, so check the company's Georgia residential or general contractor license on GOALS Verify Now if repairs are part of the work.

A note for Rex renters
Georgia law makes the landlord responsible for keeping a rental in repair (O.C.G.A. 44-7-13). Send your request in writing. Clayton County Code Enforcement says it does not deal with mold directly, but it may act on the plumbing problems and leaks behind it. This is general information, not legal advice.
