How to Clean Up an Indoor Mold Problem
The EPA suggests that indoor mold growth less than ten square feet can be considered a small problem. If the growth covers a larger area, it is a good idea to contract a professional mold remediator. (EPA Mold Clean Up) The following guidelines should be used when performing a mold remediation:
1. Before beginning remediation activities, contain the contaminated area from non-contaminated areas and establish a negative-pressure work zone. This can be done utilizing a HEPA air filtration device (AFD) and exhausting to outside air. HEPA air filtration should run 24 hours minimum after completion of remediation activities. Where possible, heating, ventilation, and air conditioning should be turned off during the remediation.
2. Once remediation activities begin, airborne mold concentrations can increase many times. Workers should utilize a half-mask respirator with HEPA filtration when remediation activities commence. (What to Wear)
3. Remove and dispose of porous, organic, non-structural materials that show signs of mold growth or water damage. (Clean Up Guidelines)
4. Once mold-contaminated materials have been removed, HEPA vacuum entire the area then thoroughly clean all areas with an EPA-registered biocide solution or similar product.
5. Porous materials, such as wood, that are structural in nature and show signs of water damage or mold staining after cleaning, may be encapsulated with a sealant that inhibits mold growth.
6. Once remediation activities are completed, a final inspection should be performed.
