The remediation specialist will inspect all areas noticeably affected by mold damage and determine the condition of mold contamination (1, 2, or 3). He will perform moisture checks in drywall, flooring, structural cavities, and any other potentially damaged materials to help determine the extent of the damage. Pre-remediation laboratory air analysis will be performed at this time, and a scope of work from a licensed mold assessor may be requested. We will note any personal items that have been damaged and those which need to be removed from the affected area. Before work begins, personal items will be removed from all contaminated areas. We can also recommend contractors for the re-build process.
Five basic principles should be followed on all mold removal jobs. These principles are meant as guidelines, and every job is different.
Mold contamination can lead to a number of health problems, both for those residing in the structure and for anyone working to remove the problem. Anyone involved in the mold remediation process should protect themselves using Tyvek suits, respirators, goggles, gloves, and other personal protection equipment any time they are in the affected areas.
Testing for mold contamination on surfaces and in the air should be performed both before and after remediation. This helps determine the type of mold containment, the severity of the problem, and how successful remediation has been once complete.
It is extremely important to contain the work area with negative air pressure to prevent the mold spores from spreading to other areas of the structure. We use temporary wall systems, block HVAC vents, and create negative air pressure with HEPA filtered air scrubbers to achieve this. These air scrubbers are placed inside the containment area and vented outside the structure to create negative air pressure to remove contaminated air. Without proper containment, mold spores can spread to unaffected areas of the home, causing additional damage.
Removal & Decontamination
Bleach alone does not kill mold and attempts to isolate mold or remove visble signs from the surface are not adequate. Porous contaminated materials including drywall, furnishings, cabinets, and other items must be physically removed from the structure to remove mold. Soda blasting, sanding, or other removal methods may be used for studs and other structural materials. Decontamination should be accomplished to the extent possible by cleaning. Cleaning removes contaminants, microorganisms, and their food sources from an environment. All surfaces in the work area are vacuumed using a HEPA filtered vacuum and wiped down with an antimicrobial. ULV fogging, sealing of studs and other areas with a mold blocker, and additonal cleaning may also be performed.
To limit future contamination or recontamination, moisture problems such as leaks or high humidity problems must be identified, located, and corrected or controlled as soon as possible. Mold growth is inevitable if moisture is not controlled.
