Mold-resistant paint and surface sprays slow growth on dry surfaces, but they do not address the moisture that feeds it. In New Orleans, indoor humidity regularly climbs above 60 percent after summer storms, and older homes with aging drywall and wood framing absorb that moisture quickly. If the source, a leaking roof flashing, a clogged HVAC drain pan, or a crawl space without a vapor barrier, is not corrected first, any surface treatment is temporary.
Our partners arrange an on-site assessment that covers the specific components most likely to introduce or trap moisture: bathroom exhaust fans sized for the room’s volume, crawl space venting and vapor barriers, HVAC drain pan condition, exterior gutter drainage, and roof penetrations. Humidity readings are taken in affected rooms to establish a baseline. The written plan that follows targets each identified gap, not a generic checklist.
A target indoor humidity of 30 to 50 percent is the practical benchmark for discouraging mold growth in most home environments. Reaching and holding that range in a New Orleans home typically requires a combination of mechanical dehumidification, adequate exhaust ventilation, and sealed crawl space conditions, not a single product. The assessment identifies which of those components is missing or underperforming before any work is arranged.
