What is Mould

Mould is all around us. It is a natural part of our planet. Mould has many benefits to our ecosystem as well as our food source. However, there are certain mould species that can be extremely harmful and should not exists in significant concentration in our indoor environment.

Mould growth also produce mould spores. Mould spores are easily aerosolized and are a natural part of the air outdoors as well as indoors. However, a mould growth issue indoors can result in an un-natural or elevated concentration of mould spores in our breathable air. If the mould spore species contains toxins (mycotoxins) then negative health reaction are possible. Moulds like this include black mould which we commonly remove from Toronto homes all the time. These health issues can be minor and temporary to serious and life altering depending on the type or species of mould and concentration.

Cellulose building materials such as the paper on drywall, wood framing, certain flooring materials, even decorating materials and contents can grow mould. The crucial factor or catalyst is moisture.

A water leak, plumbing issue, appliance overflow, condensation and any kind of elevated humidity or basement leak, window leak roof leak or flood can introduce unwanted moisture into a building.

Should a moisture issue be present for several days…your run the risk of mould growth.

Mould Needs 4 things to grow:

Mould spores

(there are all around us and already in the air indoors and outdoors)

Cellulose material

(most buildings contain cellulose materials)

Moisture

(flood, leak, spill, condensation, high humidity)

Time

(if areas remain wet for more than 5 days, mould will grow)
