Moulds are found in nature and are necessary for the breakdown of vegetation.  Moulds can be present within buildings from the infiltration of spores of the outdoor air or can grow on interior surfaces because of the presence of moisture from flooding, plumbing and roof leaks and excessive humidity conditions.

The key to addressing mould problems in buildings is to control moisture.  Mould can grow almost everywhere on any surface providing moisture is present.  

Christopher Collett and Associates Ltd. works with our clients to investigate, assess, manage and remediate mould related concerns.  Our services include:

A useful document which provides guidance to owners and building managers when they are addressing mould issues is the Canadian Construction Association's Mould Guidelines.
