Black mold, including Stachybotrys, grows in persistently damp conditions and penetrates porous materials fast. In New Orleans, flooding history means mold behind drywall or under flooring is a routine inspection finding, not an edge case. The subtropical heat accelerates colony spread, so what looks like a small patch on a baseboard often extends further into the wall cavity than the visible surface suggests.
Our partners set up negative-pressure containment before any material is disturbed. That keeps spores from migrating to adjacent rooms during removal. Affected drywall, insulation, and wood framing are extracted, bagged, and removed from the property. HEPA vacuuming follows on all exposed surfaces, and an air scrubber runs throughout the job to capture airborne particles down to 0.3 microns.
The moisture source that fed the growth is identified and documented in the written scope, without that step, regrowth is likely regardless of how thorough the removal was. Antimicrobial treatment is applied to treated framing before drying begins. A post-remediation moisture reading confirms the area is dry, closing the job with a verifiable result rather than a visual check.
Scope of Work
What black mold removal covers
From a single bathroom wall to a flood-damaged crawl space, the scope is set by what the inspection finds.
Containment & Negative-Pressure Setup
Sealed barriers and negative air pressure isolate the work area so spores stay contained during removal.
Drywall & Insulation Removal
Affected drywall and insulation are cut out, bagged, and removed, not treated in place and left behind.
Wood Framing Treatment
Exposed framing is HEPA-vacuumed and treated with antimicrobial solution before the drying phase begins.
HVAC Duct Inspection
Ductwork is checked for mold spread so spores are not recirculated through the home after remediation.
Crawl Space & Attic Remediation
Subfloor, joists, and attic decking are inspected and treated where moisture has reached structural materials.
Moisture Source Identification
The leak, condensation point, or drainage issue feeding the growth is located and documented in the written scope.
Post-Flood Mold Removal
Covers storm and flood-related mold behind walls and under flooring.
Historic Home Remediation
Adapted approach for older wood-framed homes with porous materials.
Dehumidification & Drying
Industrial dehumidifiers run until moisture readings confirm dryness.
Clearance Testing
Post-remediation testing documents the area is clear before close.
Why Choose Us
Why New Orleans Mold Remediation for black mold removal?
Every job starts with an on-site inspection and a written scope, no guesswork, no work booked without a technician seeing the property first.
Inspection Before Any Scope Is Written
A technician visits the property first. No removal is planned or priced until the moisture source and spread are confirmed on-site.
Written Scope Covers Every Stage
Containment method, removal plan, and post-remediation clearance testing are all documented before work begins.
Flood & Storm Mold Experience
Our partners handle flood and storm-related mold regularly, the kind found behind walls and under flooring after water intrusion.
Historic Home Know-How
Older wood-framed homes need a different approach. Our partners are familiar with the materials and construction common in New Orleans housing stock.
Crawl Space & Attic Coverage
The scope extends to crawl spaces and attics when the inspection finds moisture has reached structural or insulation materials there.
Verifiable Close, Not a Visual Check
Post-remediation moisture readings give a measurable sign-off, the job is not marked complete on appearance alone.
Disturbing mold without containment spreads spores to rooms that had no growth. If the affected area is larger than a few square inches, is inside a wall, or keeps coming back, a contained removal is the safer path. DIY cleanup can make the spread harder to control.
Why does black mold keep coming back after cleaning?
If the moisture source, a slow leak, poor ventilation, or residual flood damp, is still active, mold regrows even after thorough surface cleaning. The moisture source has to be identified and addressed alongside the removal, or the cycle repeats.
What happens if I delay black mold removal?
Black mold colonies spread through porous materials quickly in humid conditions. A patch on one wall can extend into adjacent cavities, insulation, and subfloor within weeks. Delay increases the volume of material that needs removal and raises the overall scope of the job.
What does the inspection check before removal starts?
The on-site inspection locates the moisture source, maps visible growth, and checks whether mold has spread into wall cavities, flooring, ductwork, or structural framing. That information sets the written scope, no work is planned without it.
Does bleach kill black mold in walls?
Bleach reaches surface growth on nonporous materials but does not penetrate drywall, insulation, or wood framing where black mold colonies live. Applying it to a porous surface can leave active mold inside the material while the surface looks clean.
Does flood damage always mean mold inside walls?
Not always, but in New Orleans it is a frequent finding. If walls or flooring stayed wet for more than 24 to 48 hours after a flood or storm, mold growth inside the cavity is likely. An inspection with a moisture meter is the only way to confirm the extent.
