Mould Investigation and Remediation

Mould may germinate and flourish on any organic substrate (paper, wood, cardboard, dust, textiles etc.) if the correct conditions exist.

The right conditions for mould growth include the absence of UV light, high moisture, and the lack of ventilation. Many moulds will grow over a wide temperature range while others prefer either hot or cold environments. Most of the moulds encountered in residential and commercial sites flourish at temperatures within the human comfort range.

When mould is disturbed, spores become airborne and spread in the immediate environment. These spores can lay dormant until ideal situations as mentioned above occur in which case they can germinate and grow. Some harmless but others can be potentially hazardous to people with immunity susceptibilities caused by an existing medical illness such as cancers or respiratory weaknesses, as well as the elderly and expectant mothers. Regardless of the degree of hazard, all moulds are considered allergenic and will affect each person differently.

Because of the ease with which mould spores spread and the possible health implications mould should only be removed using approved widely accepted removal technics under the guidance of a Qualified Mould Remediation Consultant. Pario’s team has remediated hundreds of residential and commercial sites with the co-operation of numerous independent remediation contractors.

Whether the mould growth is a result of a covered Insurance loss or just occurring due to the existence of the right circumstances, Pario can provide the following services:

  • Inspect and provide opinions based on visual observations
  • Sample the affected areas to identify the types of moulds present
  • When excessive mould presence is confirmed, provide recommendations for abatement procedures for remediation
  • Provide supervision to ensure that appropriate abatement protocols are engaged and followed
  • Provide visual and air clearance inspection and sampling, and surface sampling (if necessary) to confirm that the mould has been affectively remediated

Designated Substance Surveys and Remediation

Throughout Canada, many provincial regulatory occupational health and safety departments require before beginning a renovation/restoration project, the owner shall determine whether any hazardous substances are present at the project site and shall prepare a list of all designated substances that are present at the site. The presence and handling of designated substances may pose an increased health risk to workers and these substances may require special treatment if they are to be disturbed during work at a site.

Designated hazardous substances could include but not limited to:
1. Acrylonitrile
2. Arsenic
3. Asbestos
4. Benzene
5. Coke oven emissions
6. Ethylene oxide
7. Isocyanates
8. Lead
9. Mercury
10. Silica
11. Vinyl Chloride

Some provinces may refer to designated substances by other names such as toxic substances, hazardous substances or chemical/biological substances. In addition, different areas may include other hazardous materials such as PCB’s and CFCs and mould.

Pario can assist clients with designated material concerns by:

  • Locating and identifying hazardous substances
  • Sampling suspect materials
  • Evaluating the hazard and level of risk
  • Developing a management or remedial plan to control the risk
