Mould remediation: Understanding the process

While a mould removal specialist is conducting mould remediation, facilities managers should understand the process to minimise disruption and assist in planning to ensure existing operations remain uninterrupted.

Determine the degree of contamination. The first step for a mold remediation specialist may be determining the extent of the mould damage and test for contamination within the facility. Because spores and other contaminants invisible to the eye spread through the building affecting other areas, the specialists may collect sample for analysis from affected as well as unaffected areas of the building. Once this step in the inspection process is complete, the mould removal specialist begins the remediation process to return the facility to it’s original condition.

Set up and verify containment. To ensure mould contamination does not spread, isolation barriers will be set up to prevent contamination. Once the containment is verified, the removal process can begin.

Remove unsalvageable and damaged materials. Porous materials and items that cannot be restored or cleaned effectively must be carefully discarded. Unsalvageable items include but are not limited to drywall, insulation, and other items with visible mould growth.

Cleaning surfaces with a high-attention to detail. A thorough vacuuming of contaminated areas using a HEPA vacuum with a high-efficiency filter to catch mould spores is the first step taken by specialists

Verify remediation. Once cleaning is complete, a verification of the remediation process is one of the final steps. The area must be returned to the dry standard and should be visually dust free with no mould odours. In addition, separate checks may be performed on surface or air sampling as part of the verification that the area is back to normal fungal ecology.
