Safe Mold Removal for Properties in Greater St. Louis
Disturbing affected materials can send dust and mold spores into clean rooms, making containment important.
Hidden Materials Can Stay Damp
Your insulation, subfloor or framing could still be wet despite a surface appearing dry. Moisture readings help establish your affected area.
Some People Face More Risk
Mold may bring on symptoms of allergies and asthma for some people. According to the CDC, higher risk applies to people with asthma, lung disease or weakened immune systems.
Color Does Not Measure Risk
People use black mold and toxic mold as search terms. According to the CDC, mold color cannot tell you the level of risk.
Mold Spores Can Spread
Drywall cutting and carpet pulling can send particles into the air. HEPA filtration with negative air pressure helps restrict movement.
Selecting Your O Fallon Mold Remediation Company
Use Independent Clearance Testing
If post-remediation verification is needed, an independent assessor avoids having the removal company check its own work.

Find out how condensation, leaks or excess humidity will be located and fixed.
The Mold Remediation Process Across Greater St. Louis
Follow mold remediation steps in sequence: assess, set up containment, remove damaged material, clean and dry, verify results, and finally dismantle containment.
Mold Inspection and Moisture Mapping
To trace affected materials and the moisture source, use a moisture meter and, where helpful, a thermal imaging camera.
Containment and Air Filtration
A containment barrier is made using poly sheeting. A HEPA air scrubber is an air filtration device that, with negative air pressure, limits particle movement into clean rooms.
Removal of Damaged Materials
Protective equipment is used by workers. You may need drywall removal or demolition of other porous materials damaged by mold.
Surface Cleaning and Drying
For non-porous surfaces left in place, cleaning uses a HEPA vacuum plus damp wiping. Drying relies on a dehumidifier, air movers and moisture readings.
Final Cleaning and Verification
Post-remediation verification can involve clearance testing, a visual examination or air sampling, carried out by an independent assessor.

Common Questions About Mold Removal in 63366
How can mold cleanup be contained inside a condo or apartment?
The work area can be isolated with plastic sheeting and negative air pressure. Access to shared walls, ventilation or plumbing may have to be arranged by a property manager.
