What Goes Wrong

Where rushed flood cleanups fail, and what a thorough job looks like instead

Surface-Only Cleaning

Wiping visible mold on drywall leaves moisture and spores inside the wall cavity, where regrowth starts within days.

Moisture Mapping First

Moisture readings across walls, floors, and ceilings map the full wet zone before any scope is written or work begins.

Bleach on Wet Walls

Bleach does not penetrate drywall paper or insulation batt, and it does nothing for moisture still held in the material.

Material Removal & Drying

Wet drywall, soaked insulation, and damaged subfloor sections are removed, bagged, and replaced only after meter readings confirm dryness.

Crawl Space Ignored

Storm water pools in crawl spaces and under pier foundations, and a surface-focused cleanup leaves that moisture untouched.

Separate Crawl Inspection

Crawl spaces are inspected independently, with structural drying equipment run until readings reach acceptable moisture levels.

No Containment Setup

Removing moldy material without containment barriers spreads spores into unaffected rooms through air movement and foot traffic.

Containment & HEPA Filtration

Containment barriers and HEPA air scrubbers are installed before any material is disturbed, keeping spores out of clean areas.

Post-Flood Cleanup

Flood mold hides in walls and subfloors, surface cleaning will not stop it spreading

Mold begins growing inside wet drywall and insulation within 24 to 48 hours of water intrusion.

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.

Why Choose Us

Why New Orleans Mold Remediation for flood & storm cleanup

Post-flood jobs need a process built around hidden moisture, not just visible mold, here is how our partners deliver that.

Inspection Before Any Scope

No work is booked until a technician has completed an on-site moisture inspection and written up the full scope.

Written Scope Every Time

The written scope names the containment method, removal approach, and post-remediation clearance test before work starts.

Flood & Storm Specialization

Our partners handle storm surge and heavy-rain jobs specifically, not just routine mold cleaning in dry conditions.

Historic Home Experience

Older shotgun-style homes and raised foundations require different drying approaches, our partners know the difference.

Crawl Space & Attic Coverage

Crawl spaces and attic spaces are inspected as part of the job, not treated as out-of-scope afterthoughts.

Common Questions

Questions about flood & storm mold cleanup

  • Do I need mold cleanup if I only see a little mold after flooding?

    Yes. A small amount of visible mold after flooding usually points to a larger moisture problem. Mold grows inside wall cavities, under flooring, and in insulation where it is not visible. A moisture inspection maps the full wet zone before any scope is written.

  • Can I clean flood mold myself with bleach?

    Bleach treats the surface only. It does not penetrate drywall paper or insulation batt, and it does nothing for moisture still held in the material. If porous materials stayed wet, surface cleaning will not stop regrowth.

  • What happens if I wait before arranging cleanup?

    Mold establishes inside wet drywall and insulation within 24 to 48 hours. Waiting allows it to spread from one wall cavity into adjacent rooms and framing, which increases the amount of material that needs removal and raises the overall scope of work.

  • What makes flood mold cleanup different from regular mold cleaning?

    Flood jobs involve larger wet areas, hidden moisture in wall cavities and subfloors, and damaged materials that may need removal rather than cleaning. The job typically includes containment, structural drying, and a documented clearance check, not just surface treatment.

  • Will all the drywall and flooring need to come out?

    Not always. Moisture readings determine what can be dried in place and what has been saturated long enough to require removal. The written scope specifies which materials are removed and which are dried, based on actual meter readings.
