Most mildew in Johns Creek homes can be scrubbed off hard surfaces once you bring indoor humidity down, and the EPA says patches under about 10 square feet are usually a homeowner job. If it is on drywall, keeps returning or covers a larger area, have it looked at. Call the number on this page to be connected with a local mold remediation company in Johns Creek.

A quick local picture
Johns Creek is a northeast Fulton city about 22 miles from Atlanta, formed in 2006 from crossroads communities such as Newtown, Ocee and Warsaw. The Chattahoochee forms its southern edge, and the creek the city is named for feeds into it. Many homes here have finished basements, and low rooms near the river corridor hold summer humidity longer than upper floors.
What to do now
- Measure. Put a hygrometer in the problem room for a day. The EPA recommends keeping indoor humidity below 60 percent, ideally 30 to 50.
- Find the water. Check for a weak bath fan, a sweating cold-water pipe, a dripping AC drain line or a damp basement wall.
- Protect yourself. Wear gloves and eye protection, and an N-95 respirator if you will be close to the growth for a while.
- Clean hard surfaces. Scrub tile, glass, metal and sealed wood with detergent and water, then dry them completely.
- Decide on soft materials. Carpet, ceiling tile and fabric that stay musty after cleaning may need to go, the EPA notes.
- Watch for two weeks. If the film comes back in the same place, the moisture source is still there.

Signs and what they usually mean
| What you see | Likely cause |
|---|---|
| Gray film on shower grout and ceiling | Bathroom fan too weak or not run long enough |
| White fuzz on stored boxes in the basement | High humidity in a below-grade room |
| Dark spots at the bottom of a finished basement wall | Moisture wicking through the foundation |
| Musty smell from supply vents | Condensation in ductwork or a clogged drain pan |
| Spotting on sills every morning in winter | Condensation on cold glass |
What affects the cost
A bathroom cleanup is the smaller end; Angi's Atlanta cost guide reports bathroom mold work at roughly $587 to $1,174 and basement work from about $587 to $3,522. Price climbs when drywall or carpet has to be removed. Johns Creek requires a building permit for interior alterations that include drywall or framing, so rebuild work after removal goes through Community Development's Building and Permitting office (678-512-3250). Ask the company whether it holds a Georgia residential or general contractor license if it will do that work, and check it on GOALS Verify Now.
