Attic mold in Rex usually comes from a roof leak, an attic air handler that sweats or overflows, or moist air trapped under the roof deck. Removing it means fixing that source, pulling wet insulation and cleaning or replacing the affected wood. Call the number on this page to be connected with a local mold remediation company in Rex.

What usually causes attic mold in a Rex house?
Rex is an unincorporated community of about 16,600 people in eastern Clayton County, about 13 miles from Atlanta, with a historic village center around the Rex Mill. Its homes deal with the usual metro triggers. Roof leaks begin at valleys, vent boots and chimney flashing, often after thunderstorms or long rainy spells; Clayton County was under a state of emergency during the September 2009 floods. Inside, attic air handlers and ducts run cold through humid summers, so a clogged condensate line or a poorly sealed duct can wet insulation for weeks. Fans that exhaust into the attic and soffit vents blocked by insulation trap moisture against the cool deck overnight.
Who issues permits for repairs in Rex?
Because Rex is unincorporated, building permits come from the county. Clayton County Community & Economic Development handles them from the P.K. Dixon Building on South McDonough Street in Jonesboro and offers an online permit and inspection portal. Mold cleanup itself isn't described as permitted work, but replacing decking or rafters can be. Rex sits near the Henry County line, so confirm which county your address falls under before applying. Georgia has no state mold license; for the carpentry, ask whether the company holds a Georgia residential or general contractor license and check it on GOALS Verify Now.
What does it cost, and what changes the number?
Angi's Atlanta cost guide reports $1,174 to $4,696 for attic mold remediation and about $12 to $29 per square foot for most mold jobs. HomeGuide's 2026 national ranges are $1,500 to $6,000 for a partial attic and $6,000 to $15,000 for a full one. The size of the moldy area, how much insulation must be replaced, the attic's clearance and whether any sheathing has to come off set the final price. Roof and HVAC repairs are usually billed separately.

A note for Rex renters
Clayton County Code Enforcement handles property maintenance in unincorporated areas and says it doesn't deal with mold directly, but it may act on the leaks and plumbing problems behind it. Under O.C.G.A. 44-7-13, landlords must keep rentals in repair; make your request in writing and keep a copy. This is general information, not legal advice.
