Mildew in Newnan homes appears on bathroom surfaces, plaster and painted walls, closets and around older windows during humid months.

Why Newnan homes get it
Newnan is the Coweta County seat, a city of about 42,500 people roughly 34 miles southwest of Atlanta, known for antebellum and early 20th-century homes that were largely spared in the Civil War. Older houses often have plaster walls, original windows and crawl spaces, all of which can hold or pass moisture in humid weather. Newer subdivisions face the same summers, with mildew showing up most often in bathrooms and closets.
An EF4 tornado struck Newnan on March 26, 2021, damaging structures including in the historic downtown. Storm damage that lets rain into walls or attics is a common route to mold if materials are not dried within 24 to 48 hours, as EPA advises.
In older homes, a crawl space under the original part of the house often feeds the musty smell in rooms above, so look there first.

Cost factors
Angi's Atlanta cost guide reports bathroom mold work at about $587 to $1,174, with larger jobs at roughly $12 to $29 per square foot. In older homes, careful work around plaster, trim or original materials can add time. Removal of drywall, insulation or carpet, containment and any repair of the moisture source also raise the total. The City of Newnan Building Department issues permits, including minor repair permits, within city limits if walls or framing have to be replaced.
What happens when you call
You will be connected with an independent local company and asked where the growth is, what material it is on and whether there has been a leak. On site, the company should take moisture readings, check windows, plumbing and ventilation, and give a written plan. Georgia law defines a residential contractor by work over $2,500, so for larger repairs ask whether the company holds a Georgia residential or general contractor license, check it on GOALS Verify Now and confirm current rules with the state licensing board.
