Under-House Mold
Mold-free joists, dry framing, and a written scope before any work begins, for good.
What Goes Wrong
The failure is almost always in what gets skipped, not what gets cleaned.
Wiping visible mold off joists without a moisture reading leaves the damp conditions intact, so regrowth starts within weeks.
A calibrated moisture reading across joists and subfloor locates the source before any treatment begins.
Working without containment pulls spores into the living area through floor gaps and HVAC returns during the cleanup itself.
Containment barriers are installed to the affected zone before any disturbing or removal work starts.
Saturated insulation holds moisture against wood framing long after the visible mold is treated, feeding regrowth from inside the batt.
Wet insulation and failed vapor barriers are pulled out and disposed of so no moisture reservoir remains against the wood.
Treating wood framing in a crawl space that still runs above 60% relative humidity means the mold returns on the same surfaces within a season.
A replacement vapor barrier, encapsulation coating, or dehumidifier is installed to keep humidity at a stable, mold-resistant level.
Scope of Work
Every job addresses the full crawl-space environment, not just the visible mold on the surface.
Calibrated moisture readings across joists, subfloor, and vapor barrier identify every damp zone before the scope is written.
Barrier containment isolates the work area so spores cannot travel into the living space through floor gaps during removal.
HEPA vacuuming followed by antimicrobial application rated for porous wood surfaces treats joists and subfloor thoroughly.
Saturated insulation and failed vapor barriers are removed and disposed of, eliminating the moisture reservoir against the framing.
A replacement vapor barrier or encapsulation coating is installed to seal ground moisture away from wood framing permanently.
A dehumidifier sized for the crawl space holds relative humidity below 60%, the threshold above which mold regrowth accelerates.
Confirms the space meets clearance standards before the job closes.
Checks ductwork in the crawl space for mold contact.
Louisiana-required documents provided before work starts.
Why Choose Us
Crawl-space work has specific risks, here is what makes the difference on this type of job.
You receive a documented plan covering containment, removal method, and clearance testing before a single tool is picked up.
Every job starts with calibrated moisture readings, not a visual guess, so the source is confirmed before treatment begins.
Written contracts and consumer disclosures required by Louisiana law are prepared and provided on every job, without exception.
Clearance testing after treatment confirms the crawl space meets the required standard, not just that it looks clean.
Partners handle crawl spaces alongside water-intrusion damage, so related moisture problems are scoped in the same visit.
Vetted independent local partners serve the Baton Rouge area and understand the humidity and housing conditions here.
How It Works
01
Submit your details and a local technician is arranged to visit, take moisture readings, and assess the full crawl-space condition.
02
You receive a written contract covering containment method, materials to be removed, treatment approach, and post-remediation clearance testing.
03
The technician completes containment, treatment, material removal, and moisture correction, then clearance testing confirms the space is clean.
