Mold removal and Clearance Tests

So you’ve seen mold and called a mold removal contractor. You may even have interviewed several mold remediation companies and chosen the one you thought was best for the job. The work was done. The contractor was polite, on time and appears to have removed the mold as promised. The visible mold growth is gone, the odour appears to have decreased or even gone away completely. Why a Clearance Test?

Even the best mold remediation contractor, following all the proper guidelines and mold remediation protocols will not know if airborne mold spores are an issue without a proper Clearance Test.

Mould growth has basically two main issues. There is the actual growth that is affecting the building material that sustained the water damage, and then there are the mold spores which can travel to other areas of the building and lead to health issues.

In most cases when mold growth is disturbed through, cleaning, cutting, wiping or any other activity, mold spores are disturbed which become airborne. This is why in most cases mold remediation is performed under containment or inside a plastic enclosure. Even lightly misting mold growth with water or air flow over an area of mold growth can lead to mold spores being disturbed.

Mold spores that are disturbed will become airborne and travel to other areas of the building. These spores can lead to additional mold growth in other areas of the building should they land on damp or wet areas. In addition, it is the mold spore that carries the mycotoxin that can lead to allergic reactions or health issues depending on the species of the mold spore.

This is what a mold remediation clearance test is for. It is to determine, if the mold remediation was successful in not only removing all of the mold growth, but also to ensure mold spores were also not aerosolized or spread to other areas.

A clearance test also provides independent proof or documentation to all parties involved that the work was completed properly and successfully. The homeowner is assured that the mold was removed without spreading spores and the contractor has proof they performed the work fully. Should mold growth re-occur, then it is not part of this water or mold issue but of a separate event.

It is important that the mold remediation contractor who performed the work, does not perform the clearance test. A clearance test should only be performed by an independent consultant using an independent laboratory. It is an obvious conflict of interest for a mold contractor who removed the mold to perform the clearance test. A contractor will be motivated to find in his own favour as opposed to providing an independent review of the work performed.

Did you know?

Using biocides or bleach to kill mould does not have any advantages. Dead mould is just as toxic as mould that is alive. Cleaning or removing mould without protecting the rest of the building or unaffected areas can in some cases spread the mould contamination. In some cases the mould becomes harder and more expensive to clean up. Some mould inspection companies lack the equipment or experience to properly assess you mould issue. They are cheaper...but are they worth it?
