If your O'Fallon home had water damage — even a minor leak — and wasn't properly dried within 48 hours, there's a good chance mold is growing somewhere. Our IICRC AMRT-certified technicians use moisture meters, thermal imaging, and visual inspection to find it, then contain, remove, and treat with professional antimicrobials.
Our Mold Remediation Process
Mold Inspection
Our IICRC-certified techs inspect your O'Fallon property, find the moisture source feeding the mold, and map the affected area. Independent testing gives you proof of what we're dealing with.
Containment & HEPA Filtration
Full containment with negative air pressure prevents mold spores from reaching clean areas. HEPA scrubbers run continuously. Our crew enters and exits through sealed openings only.
Removal & Treatment
We cut out affected drywall, insulation, and other materials safely. Structural wood and concrete get antimicrobial treatment. Everything is done inside containment with HEPA filtration running.
Verification & Sign-Off
Third-party air testing confirms remediation was successful. We don't release containment until clearance testing passes. Your results come from an independent lab, not from us.

Why Choose 24/7 Water Damage for Mold Remediation?
Find the Source
Killing mold without fixing the moisture source is a waste of money — it grows back. We find the leak, the condensation issue, or the ventilation problem and fix it as part of the job.
IICRC S520 Protocol
We follow IICRC S520 mold remediation standards on every job — containment, HEPA filtration, safe removal, antimicrobial treatment. Not a simplified version. The real protocol.

Containment is the most important step and the one most companies cut corners on. We build a full chamber with 6-mil poly and negative air pressure — air flows in, not out. HEPA scrubbers filter continuously. Techs wear respirators and Tyvek suits. After removal, every surface gets HEPA-vacuumed and antimicrobial treatment.
Mold remediation in O'Fallon typically runs $1,500 to $8,000 depending on scope. Insurance may cover it if the mold resulted from a covered water event. We handle documentation and claims coordination. Call (866) 993-3605 for a free assessment.
