Mould FAQs

What is mould?

Moulds are microorganisms that multiply as they grow producing thousands of tiny particles called spores. Actively growing moulds are typically colourful with a fuzzy or slippery surfaces and can appear in many colors including red, blue, brown, green, white, or black. When disturbed, moulds release their spores into the air and can form other colonies of mould in different locations. 

Mould requires moisture to grow and remain active. Inactive mould is typically dry and powdery and, if disturbed, can become airborne and be deposited in various locations. Add moisture to that inactive mould and it will be activated and begin to grow producing spores.

Poorly ventilated buildings can produce excessive humidity, and buildings sustaining water damage from leaks from plumbing, roofs, windows or walls or from flooding are all breeding grounds for mould.  Mould is toxic to people living or working in those buildings.

Remediating water damage as soon as it occurs with proper and adequate drying will drastically decrease the chances of mould growth

Where is mould found?

Mould can be found wherever moisture is present and especially in areas with low lighting and poor air circulation. Mould spores attach themselves to any damp surface breaking down the material as it grows. When there is a fire or flood event, moisture needs to be dealt with right away to deter the growth of mould.

How quickly does mould grow?

Mould begins to grow as soon as its spores attach to a surface and colonize in 1 to 12 days often becoming a problem before it is visible. Mould is difficult to destroy and may return if appropriate remediation is not implemented.

How do I know if mould is present in my home or business?

Mould may be present if the following occurs or are detected:

  • Fire

  • Flood

  • Plumbing leaks

  • Roof leaks

  • Flooring/walls swollen

  • Ceiling stains 

  • Black spots on surfaces 

Where does mould like to grow?

Mould can grow on almost any material that has been exposed to moist conditions and poor air circulation and can continue to exist even when the moisture problem has been rectified by going into a dormant state. Mould feeds on wood fibre and fabric materials such as wood, wall board, ceiling tiles, wallpaper, fabric and carpet, and even adhesives and paint products.
