It is important to determine the extent of the mould problem in your home to help you decide on the clean-up procedure. An area of mould is considered small if it covers one square metre or less. There should be no more than three patches of mould, with the total area staying within one square metre. Many small patches of mould in one area or throughout your home are a sign of moisture problems that need to be investigated and corrected right away.

If ignored, small mould areas may become larger over time, so it is important to clean them up before the problem gets bigger. A small amount of mould may be cleaned up using proper procedures and protective equipment.

The area of mould is considered medium if there are more than three patches of mould , but the total area is less than three square metres. In this case, assessment by a qualified professional is recommended but in most cases a medium amount of mould may be cleaned up using proper procedures and protective equipment .

An area of mould is considered large if a single patch of mould is larger than three square metres. Health Canada does not recommend that an unqualified person clean up large areas of mould. You may need a professional assessment to determine why the mould is there in the first place and how to clean it up.
