Air Quality Analyses

Our analytical laboratories are the only laboratories accredited for all areas of microbiological air quality testing by the Centre d’expertise en analyse environnementale du Québec (CEAEQ) for the Ministry of Sustainable Development, Environment and the Fight against Climate Change (MDDELCC) .

Headaches, fatigue, concentration problems, colds and flu, asthma, otitis, pneumonia, respiratory tract irritations and many skin problems can be linked, one way or another, to the air quality in your home. Children, people suffering from asthma, pregnant women, the elderly and those with an immune system deficiency are particularly vulnerable to poor air quality. Likewise, our homes contain irritants and several chemical substances from materials that are harmful and even hazardous for your health, such as moulds and vermiculite, to name a few.

This is why it is important to pay special attention to the quality of the air that circulates in our homes, by conducting analyses to identify these irritants and find solutions to make sure that the air in your home is healthy and not harmful for you and your family. All the samples collected are analyzed in our laboratories and approved by microbiologists specializing in air microbiology; our technicians comply with guidelines issued by the Canada Mortgage and Housing Corporation (CMHC).

The overall air quality analysis procedure is conducted as follows:

Assessment Procedure:

  • Use of assessment checklists
  • Overall appearance of the house/building
  • Odours detected upon arrival
  • Assessment of general- and specific-purpose rooms
  • Geographical location and drainage
  • Assessment of the characteristics of contaminants and sampling (air or surface)
  • Type of ventilation (air exchanger, VRC, etc.)
  • Assessment of biological (bacteria, mould, yeast), chemical (hydrocarbon, etc.) and physical (structure, humidity, etc.) contaminants
  • Photographs

Report and Recommendations of Improvement Measures :

  • A list of improvement measures where applicable
  • A summary of all the details noted
  • Tables of detailed results
  • Interpretation of results for the samples and analyses conducted
  • Assessment of the characteristics of contaminants and sampling (air or surface)
  • Assessment of health risks

Matrices and Equipment Used to Collect Mould and Bacteria Samples:
