Record what you're seeing
Note the location, when it appeared, any weather connection, how it's evolved, and past repairs—photos and basic measurements help the first conversation.
Read the local context
A few facts sharpen the assessment before anyone quotes. Establish whether the house has a crawl space, a basement or a slab, because that determines where the problem most likely sits. Find out whether anyone has actually been under the floor recently, since in this climate that space is where a long-running problem hides. Confirm that every exhaust fan discharges outside the roof line rather than into the attic void. And note any history of water on the property, which the parcel's flood record will confirm or rule out.
What disappears once the drywall goes back
What shows on the wall is only a symptom, not the full picture. A durable fix traces water entry, addresses humidity and the state of the underlying materials, keeps the work contained, and checks the result afterward. The scope should state clearly what gets tested and confirmed before finishes go back up.
Compare full scopes carefully
Read for how each scope handles protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranty, and change orders.
What official local sources add
Neither record governs remediation, so their value here is diagnostic rather than regulatory. The parcel's flood status tells you whether the property has taken water before, which changes what an assessment should look for -- contamination inside wall cavities from an earlier event rather than only what is visible now -- and because the city directs owners to current FEMA and state mapping, that history is checkable rather than anecdotal. The environmental strand of the 2045 plan matters at one remove: where correcting a moisture source means regrading near a stream corridor, that work is regulated even though the cleaning is not.

Roswell's historic district around the old mill site carries separate design-review rules from the surrounding subdivisions, and flood mapping near the Chattahoochee changes by parcel—confirm flood zone, historic-district status, and permit requirements with the City of Roswell before authorizing work.
