Mold in Walls & Drywall in Morrow, GA

Why walls get wet in Morrow

Morrow is a Clayton County city of about 6,600 people along I-75, roughly 12 miles from Atlanta, home to Clayton State University, Southlake Mall and the Georgia Archives. Whether the home is an apartment, a townhouse or a house, the usual causes of wall mold are leaking supply lines and drains, roof leaks that run down inside framing, AC condensate overflows in hall closets, and summer humidity condensing on cool exterior walls.

Shared walls deserve a mention. In apartments and townhouses, a leak in the unit next door or upstairs can soak your side of the wall, and that source has to be fixed on the other side before your wall can stay dry. Tell the landlord or association which unit you think the water is coming from.

What to do now

1. Track the moisture to its source and stop it if you can.
2. Dry the room with fans and a dehumidifier; EPA says to dry wet materials within 24 to 48 hours.
3. Avoid tearing into the wall yourself; disturbed mold sends spores into the air.
4. Write down when it started and take photos as it changes.
5. Renters: notify the landlord in writing and keep a copy.
6. Have a company take moisture readings before cutting.

Cost factors

Angi's Atlanta cost guide reports most pros charge $12 to $29 per square foot for mold remediation and $1,174 to $3,405 for drywall repair. HomeGuide's 2026 national ranges list a small drywall section at $500 to $1,500. The price depends on how many bays are wet, whether the leak crossed into a neighboring unit, how much insulation comes out, and how much finish work is needed. The City of Morrow Planning and Economic Development office at the Morrow Municipal Complex on Morrow Road is the place to ask about permits for the rebuild.
