Our basement flood cleanup process begins with rapid water extraction using truck-mounted pumps, followed by industrial dehumidification and structural drying over 48-72 hours. We then treat all affected surfaces with antimicrobial agents to prevent mold growth. To prevent recurrence, we recommend dehumidifier installation and may suggest drainage improvements specific to your property.

We collect air samples from multiple locations throughout your home and send them to an accredited laboratory for analysis. The lab tests for mold spore concentrations, volatile organic compounds (VOCs), and other airborne contaminants. You receive a detailed report within approximately 5 business days with clear recommendations for any remediation needed.

In many cases, hoarding cleanup is covered by insurance, particularly for estate cleanouts and situations where health or safety hazards are present. We work directly with insurance adjusters to document conditions and submit proper claims on your behalf. Contact us for a confidential consultation to determine your coverage options.

DIY mold removal carries significant risks, including spreading spores to unaffected areas and incomplete removal that allows regrowth. Professional remediation uses containment barriers, negative air pressure, and HEPA filtration to prevent cross-contamination during the process. We also perform post-remediation clearance testing to verify that mold levels have returned to safe thresholds.

O'Fallon's hot, humid summers create ideal conditions for mold growth, especially in poorly ventilated attics and basements. Common triggers include plumbing leaks, roof damage, condensation on cold surfaces, and inadequate drainage around foundations. Homes in newer subdivisions can also experience moisture issues from construction materials that haven't fully dried out.

Most mold remediation projects in O'Fallon take between 3 and 7 days to complete, depending on the extent of contamination and the areas affected. Our containment-first approach helps speed the process by isolating affected zones and allowing work to proceed efficiently. Larger projects involving structural repairs or multiple rooms may require additional time.

Yes, we stand behind our work with a clearance testing guarantee. After remediation is complete, we conduct independent third-party air quality testing to confirm mold levels are within safe limits. If clearance testing does not pass, we return at no additional charge to address remaining issues until your home meets safe standards.

Mold can begin colonizing within 24 to 48 hours of water exposure, making immediate response critical. Even minor leaks or standing water that goes unaddressed can lead to significant mold infestations behind walls, under flooring, and in ceiling cavities. If you experience any water damage, call us immediately to begin mitigation before mold has a chance to take hold.

ERMI (Environmental Relative Moldiness Index) is an EPA-developed testing method that uses DNA-based analysis to identify and quantify mold species in dust samples from your home. It provides a highly accurate moldiness score by comparing your results against a national database of reference homes. ERMI testing is especially useful for identifying hidden mold problems that standard air sampling may miss.
