Under-Floor Mold
Stop the musty smell and protect your joists, moisture controlled, wood treated, scope in writing before work starts.
What Goes Wrong
The confined, damp conditions under a house punish shortcuts that would go unnoticed in other parts of the home.
Wiping visible mold off joists without a moisture meter leaves active dampness in the wood, and growth returns within one season.
A technician reads moisture levels in the joists and subfloor before any treatment begins, following IICRC S520 assessment standards.
Opening a crawl space without containment barriers pulls disturbed spores into living areas through gaps in the subfloor and HVAC ducts.
Containment is set at the access point and HEPA-filtered equipment runs throughout removal, keeping spores out of the rest of the home.
Treating wood without reducing ambient humidity means ground vapor reactivates mold growth on the same joists within a few months.
A dehumidifier is placed after antifungal treatment to hold humidity at a stable level and prevent the conditions that caused growth from returning.
Insulation batts that have absorbed moisture and mold spores cannot be treated in place, they hold dampness and re-seed the wood above them.
Affected insulation is bagged and removed before antifungal treatment is applied to the structural wood framing that remains in place.
Scope of Work
The work addresses every material and condition that sustains mold growth under the floor, not just what is visible at the access hatch.
A technician checks joist and subfloor readings with a moisture meter before the scope is written, so no hidden dampness is missed.
Barriers seal the access point and HEPA-filtered equipment runs during removal, keeping disturbed spores from reaching living spaces above.
Saturated or mold-affected insulation batts are bagged and removed to expose the structural wood framing for direct treatment.
Antifungal solution is applied directly to joists, subfloor, and other wood framing surfaces that remain in place after insulation is cleared.
A dehumidifier is set after treatment to bring crawl-space humidity to a stable level and hold it there through the drying period.
Check existing barrier condition and coverage gaps.
Identify blocked or inadequate vents driving moisture buildup.
Testing confirms treated area is clean before job closes.
Why Choose Us
Crawl-space jobs require specific accountability at every stage, from the moisture reading before work starts to the clearance test that closes it.
Every job starts with an on-site inspection and a written scope covering containment, removal method, and clearance testing.
Work follows IICRC S520 assessment and remediation standards, the industry benchmark Louisiana does not mandate but partners use.
A moisture meter reading in the joists and subfloor is documented before treatment, so the root cause is on record, not just the visible mold.
Clearance testing after treatment confirms the crawl space is clean before the job is closed and the technician leaves the site.
Partners handle mold tied to storm flooding and rain intrusion, common across the Northshore after Gulf Coast weather events.
The Process
01
Submit your details and we arrange a local technician to visit, check moisture levels, and document what is affected under the floor.
02
You receive a written scope covering containment setup, removal method, antifungal treatment, and post-remediation clearance before any work is booked.
03
The technician completes containment, HEPA-filtered removal, wood treatment, and drying, then clearance testing confirms the crawl space is clean.
