Home  >  Services >  Microbial Contamination (Mould)

One of the most common indoor air biological contaminants is microbial contamination, which is largely attributed to fungal growth or bacteria on building materials.

Some building materials such as Gypsum Board, Wood, Plywood, Roof sheathing, Acoustic ceiling tiles and Oriented Strand Board (OSB) are very susceptible to mould growth due to their organic cellulose properties.  Other non-building related materials can also be source for concern including; boxes, papers, books, fabrics, garments, etc. These materials are present within most indoor environments.


The presence of microbial contamination (i.e. fungi, bacterial, etc.) in a building can present a health hazard to occupants of the building or to construction workers during renovation or demolition. Microbial contamination, although not specifically regulated, is a topic that is seriously addressed by most regulatory bodies and routinely enforced by Health Departments and Ministries of Labour.
