By the time you see mold on a wall in St. Louis, the colony behind it is usually ten times larger. Mold needs moisture, warmth, and organic material — MO's climate provides two for free. 24/7 Water Damage does remediation the right way: containment, HEPA filtration, safe removal, antimicrobial treatment, and third-party air testing.

Our Mold Remediation Process

1

Mold Inspection

Visual inspection plus moisture mapping identifies the scope. We recommend a third-party air test before remediation starts — independent testing keeps the process honest.

2

Seal & Contain

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.

3

Removal & Treatment

Mold-colonized materials are removed through the containment seal and bagged for disposal. Remaining structural surfaces get HEPA-vacuumed and treated with professional antimicrobials.

4

Clearance Testing

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?

Independent Verification

We recommend third-party air testing before and after remediation. We don't test our own work. Independent clearance testing proves the job was done right.

AMRT Certified

Our mold techs hold IICRC AMRT (Applied Microbial Remediation Technician) certification. They know the science behind mold growth and the proper methods for safe removal.

Liability Coverage

We carry $2M in general liability insurance and workers comp. Mold remediation involves hazardous materials — make sure your contractor is properly insured.

Full Containment

Negative air pressure containment with 6-mil poly and HEPA air scrubbers. Mold spores stay in the work zone. Your clean rooms stay clean.

Mold Remediation FAQ

Small surface mold on non-porous materials (tile, glass) — maybe. But anything behind walls, in HVAC systems, or covering more than about 10 square feet should be handled by certified professionals with proper containment. The EPA recommends professional remediation for anything over 10 sq ft.

Some mold species produce mycotoxins that can cause respiratory issues, allergic reactions, and other health problems. Stachybotrys (black mold) is the one people worry about most, but any significant mold growth should be professionally addressed.

We do free visual assessments, but we recommend independent mold testing by a third-party industrial hygienist. Hiring one company to test and remediate is a conflict of interest. We'll refer you to qualified testers in St. Louis.

About Our St. Louis Mold Remediation Services

We follow IICRC S520 and ANSI/IICRC R520 standards on every mold job in St. Louis. Documented containment, HEPA filtration, controlled removal, approved antimicrobials, and post-remediation clearance testing by an independent hygienist — not by us. Hiring one company for testing and removal is a conflict of interest.

Mold remediation in St. Louis 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.
