How can you prevent mold from spreading during remediation?

To take care of a mold problem, you must remove the mold and mold spores. You must also fix the water problem. When removing mold, it is important to prevent spores from spreading to unaffected areas. To do this, the remediator will block vents, doors, and any other openings through which spores could reach clean areas. Negative pressurization is established in the sealed area. The remediator creates low air pressure inside so that spores cannot leave.
