Mould and Bacteria Assessment

Download the brochure (French only) (.pdf)

Microbiological contamination assessments are performed to determine whether or not mould or bacteria growth is present, as these can affect occupant health. When contamination problems occur, Le Groupe Gesfor makes recommendations and offers project management services to ensure that appropriate corrective measures are taken. We can also provide specialized services for your construction and hospital maintenance work. In addition, all the laboratories that we collaborate with have the required accreditation (through the American Industrial Hygiene Association's EMPAT Program), thereby ensuring that our clients' mould and bacteria assessment results are as accurate as possible.

Here are some of the services we can provide:

• Assessment of the presence of mould- or bacteria-contaminated materials:
  1. History of water infiltrations
  2. Visual inspection of the building
  3. Intrusive inspection
