affected by moisture, becoming a food source once again. Remediation on the smallest level can involve a homeowner washing a wall or windowsill with a detergent and water solution to remove superficial mould. In this scenario, if the mould grows back, it may be time to remove the materials to further assess moisture sources. The use of biocide solutions, such as bleach or other specialty “mould killers” is not regarded as the best treatment but it can sometimes work. The problem is that a dead mould spore has the same allergenic or health effect as a live (viable) spore. Furthermore, exposure to biocides can pose a greater health risk and can be more harmful to your body than the spore exposure itself. Technically, an area of less than 10 SF can be remediated by a homeowner. However, this is complicated. Firstly, an area thought to be 2 to 5 SF can end up being 20 – 30 SF once the remediation begins. Secondly, it requires specialty PPE. Thirdly, for homes built before 1990, asbestos testing may be required before the removal of materials.
