Mold Remediation Services
in St. Louis, MO

Black mold produces mycotoxins that can cause respiratory problems, fatigue, and serious health issues — especially dangerous for children, elderly, and those with asthma. Stachybotrys chartarum thrives in areas with prolonged moisture exposure: basement walls, bathroom ceilings, HVAC ducts, and drywall behind leaky pipes. Our black mold removal process follows full IICRC S520 protocols: • Physical containment with 6-mil poly barriers and negative air pressure • HEPA-filtered air scrubbers running throughout the job • Complete removal of contaminated porous materials (drywall, insulation, wood) • HEPA vacuuming and antimicrobial treatment of all remaining surfaces • Post-clearance air sampling — third-party lab verified We do not use bleach as a primary treatment. Bleach kills surface mold but does not penetrate porous materials — the mycelia remain embedded and regrow. We use EPA-registered antimicrobial solutions designed for deep penetration.

St. Louis basements are the #1 location for mold growth — and the #1 call we get. The combination of high water table, clay-heavy soil that retains moisture, and finished basements with drywall and carpet creates ideal mold conditions. Common basement mold scenarios we handle: • Concrete block and poured wall efflorescence + mold • Wood framing and joists with mold growth from chronic moisture • Finished drywall ceilings and walls after water intrusion • Carpet padding and subfloor mold after flooding or slow leaks • Sump pump pit and floor drain surroundings Our basement remediation always includes identification and documentation of the moisture source — a crack in the foundation, failed waterproofing, HVAC condensate, or inadequate grading outside. Remediating without fixing the source is just delaying the same call.

Attics are one of the most overlooked mold locations — and one of the most common issues we find during pre-listing inspections. The cause is almost always a ventilation problem: insufficient soffit or ridge vents, blocked ventilation from insulation, or bathroom exhaust fans venting into the attic instead of outside. Our attic mold remediation: • Dry ice blasting or media blasting to remove mold from rafters and sheathing • HEPA vacuum all loose debris • EPA-registered antimicrobial treatment • Identify and document the ventilation deficiency We do not recommend painting over attic mold. Encapsulant coatings do not fix the underlying moisture problem — they just hide it temporarily. We fix the source, then treat the surfaces.
