Mold Remediation Process
Mold can be a serious health and comfort problem in indoor environments. It can exacerbate asthma and other respiratory problems and harm the health of the young and elderly. Air Care & Restoration takes a long term, professional, evidence based approach to resolving mold problems and has designed the following 12-step mold remediation process Of course, each instance of mold occurrence is unique, and the most effective solution varies from case to case; however, the major steps are similar.
The most critical step in mold remediation is thorough inspection and testing of the property by an experienced and certified indoor environmentalist (CIE) to determine the root cause of mold growth. Mold spores are present everywhere in indoor and outdoor environments; however, mold growth indoors is atypical and is nearly always caused by excessive moisture. In Mold Abatement, visible mold is removed. In-Mold Remediation as practiced by Air Care & Restoration, the root causes of mold growth is found and corrected in addition to removing all traces of mold. We also test for mold spores before and after remediation to ensure that remediation has been successful and issue a CIE-signed Certificates of Completion.
The first step is to minimize the spread of mold spores to adjoining areas by erecting a physical barrier, usually consisting of 4-mil polyethylene film sealed to the existing structure. This containment is provided with negative air pressure high efficiency particle air filtration (HEPA filtration) and sealable openings to allow entering and leaving.
Floors and belongings that cannot be easily cleaned are covered with tarps or film to minimize opportunity for damage or contamination.
Personal items and surfaces that will not be disturbed during demolition are carefully HEPA vacuumed to remove mold spores and minimize contamination of clean areas. Personal items that have been cleaned are generally removed from the containment area.
Mold contaminated or wet building materials such as carpeting, trim, dry wall, subflooring, and insulation are carefully removed within the containment, sealed in plastic bags and removed from the building.
An antimicrobial agent is applied to remaining porous building surfaces such as subflooring, floor joists, studs, roof rafters, exterior sheathing etc to ensure that mold is killed and does not return.
A common cause of mold in basements or crawl spaces is excessive weeping of concrete, cinder block, or stone walls. Air Care & Restoration treats masonry walls with a sealant designed to resist hydraulic pressure and minimize weeping of ground water into the building.
Visible surface mold is scrubbed using antimicrobial cleanser to minimize the opportunity for regrowth of mold on contaminated surfaces. Heavily mold contaminated clothing, cloth furniture, bedding, and carpeting generally must be disposed of as it cannot be reliably decontaminated.
Porous surfaces are covered with an antimicrobial coating to prevent future mold growth.
Dust, debris, and mold spores are completely removed via HEPA vacuuming.
HEPA equipped air washers are used to remove the last traces of airborne mold spores and testing is carried out after 1-3 days of recirculation.
When testing shows that mold levels have been reduced to an acceptable level, a Certificate of Completion is issued.
If desired, Air Care & Restoration can restore dry wall, trim, flooring and other building materials allowing complete restoration of the indoor space.
