Your mold removal work involves containment of the affected area, identifying the moisture source, removing uncleanable material and drying whatever can stay.

What to Do Before Calling Mold Removal Professionals in St. Louis County
Stop the water if it is safe, avoid disturbing growth and preserve useful records.
Call (844) 352-3560- Stop the water safely. Turn the leaking fixture off, or get a repair arranged. Stay away from standing water and wet electrical equipment.
- Limit access. Close the door when possible. Children and pets should stay clear of growth you can see.
- Avoid spreading particles. Containment is needed before you brush, scrape or sand mold. Stop running HVAC equipment when mold may be inside.
- Photograph the damage. Document the leak and damage to items, including visible growth, before moving anything. Ask the insurer which records it needs.
Stages of Mold Remediation
Assessment comes first in these mold remediation steps, then containment, damaged material removal, cleaning, drying, work verification and, last, removal of 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
Use poly sheeting to create a containment barrier. Clean rooms receive fewer migrating particles with negative air pressure and an air filtration device, the HEPA air scrubber.
Removal of Damaged Materials
Workers wear protective equipment. Drywall removal or other demolition of damaged porous materials may be needed.
Surface Cleaning and Drying
Clean remaining non-porous surfaces through damp wiping and use of a HEPA vacuum. Use moisture readings, a dehumidifier and air movers to guide drying.
Final Cleaning and Verification
Post-remediation verification may include a visual check, clearance testing or air sampling by an independent assessor.

Mold Cleanup: Questions and Answers
How much time should you allow for mold remediation?
Consider your affected area, the moisture source correction, drying and material removal when asking how long it takes. Request the planned order before work begins.
Is mold able to return following removal?
Mold can return if a leak, condensation or humidity problem remains. Include identification of the moisture source and an explanation of drying and moisture control in the remediation plan.
Does the process change for black mold?
Color alone does not show how risky mold is. Plan removal around materials, the affected area, containment requirements and the moisture source.
When does your situation call for professional mold removal?
EPA guidance suggests professional help when your HVAC system is affected, water damage is extensive, areas exceed about 10 square feet, or water involves sewage or contaminated water.
What is involved in checking for mold in your house?
Check around roofs, plumbing, HVAC equipment and windows for moisture signs, visible growth and a musty odor. You can trace damp material with a mold inspection. Mold testing is not required in every case with clear growth and an evident water source.
