Principles of Mold Remediation

There are six general principles used in the remediation of mold-contaminated structures and materials. These six principles of mold remediation are:

Provide for the health and safety of workers and occupants.

A mold-contaminated buildings and its contents are associated with a wide range of health problems. Occupants and remediation workers must be protected from exposure through a combination of engineering controls and specialized work practices, such as controlled demolition, containment and air pressure control, and use of appropriate respiratory protection and other personal protective equipment (PPE). If remediation is performed in an uncontrolled manner, the process may result in a significant increase in the level of airborne mold contaminants inside and outside the contained work areas.

Document the conditions and work processes.

An effective mold remediation plan cannot be developed without first determining the extent of contamination to be removed. Contaminated areas can be located using sensory (visual, olfactory) investigative techniques, although it may be difficult or impossible to locate all growth without use of intrusive or destructive techniques. Baseline contamination testing is conducted by air sampling and tape lifts to identify the type, level and location of contamination. A remediation plan is then prepared based upon the test results. To ensure that remediation work has been performed properly post remediation testing is conducted to assure that contaminates were returned to safe levels.

Control the contaminant at its source.

During the remediation process mold contamination is controlled as close to its source as possible. When mold spores are aerosolized, they become much more difficult to capture. It is important to prevent aerosolization. Control of the contaminant is accomplished by the use of source containment. During remediation, control of contaminant and dust generation is accomplished with the use of engineering controls, vacuum assisted demolition tools and locating an air filtration device as close to the work area as possible.

Physically remove the contamination (source removal).

The source of mold contamination is physically removed, attempts to kill or encapsulate mold are not adequate to solve the problem. The area is sealed off and abatement is performed by certified professionals.

Correct the moisture problem to prevent recontamination.

Since mold spores are present at background levels in a normal fungal ecology, mold growth is virtually inevitable if moisture is not controlled. To prevent this, moisture problems must be identified, located and corrected or controlled as soon as possible. Reconstruction shall not begin until moisture is controlled, mold remediation is complete and materials are dry. Structural drying will be considered completed when the moisture count of the sub flooring and framing reach 8-12% WME (wood moisture equivalent).

Provide a Post Remediation Validation Test (PRVT)

This is the final step in any Mold Remediation project. This test is accomplished to assure that the Environmental Health of the property has been returned to acceptable conditions. This test and evaluation demonstrats the success or failure of the Remediation Project and no Remediation Project is complete without one.

MOLD REMEDIES GUARANTEE

We guarantee that, based on the scope of the workspace areas treated, that these workspaces will pass Post Remediation Validation Testing (PRVT) or we shall re-clean & re-treat for FREE!
