New Orleans sits below sea level, and ground-floor units, crawl spaces, and raised-foundation subfloors are the first places to hold water after heavy rain or storm surge. Older shotgun-style homes with wood subfloors and pier foundations trap moisture in ways that are not visible from inside the living space. By the time a musty odor is noticeable, mold is typically already established inside wall cavities and under flooring, not just on surfaces.
Bleach applied to a wet wall treats the surface only; it does not penetrate drywall paper or insulation batt, and it does nothing for the moisture still present in the material. Our partners take moisture readings across affected walls, floors, and ceilings to map the full wet zone before the scope is written. Containment barriers and HEPA air scrubbers are installed, then wet drywall, soaked insulation, and damaged subfloor sections are removed and bagged for disposal.
Dehumidifiers and structural drying equipment run until meter readings confirm materials have reached acceptable moisture levels. Crawl spaces are inspected separately, storm water pools there and is frequently overlooked in a surface-focused cleanup. The job closes with a final moisture check across all previously affected areas, giving you a documented baseline rather than a visual estimate of whether the space is dry.
