When Mold Testing May Be Needed

Mold is a common term used to describe fungal growth that may appear on building materials, finishes, or other surfaces when moisture is present. It may appear as staining, spotting, discoloration, visible growth, or may be associated with a musty odour.

Mold concerns should be evaluated carefully because visible staining does not always confirm the type or extent of contamination. Laboratory testing can help identify whether mold spores or fungal growth are present in collected samples.

Common moisture sources that may contribute to mold growth include water infiltration, roof leaks, plumbing leaks, high indoor humidity, condensation and poor ventilation.

Mold may develop on or behind building materials such as drywall, wood, carpets, window areas, kitchens, bathrooms, laundry rooms, basements and other damp areas. If mold is suspected, professional evaluation and laboratory testing can help determine whether further action by a qualified remediation contractor may be required.

What Mold Testing May Identify

Mold testing may help identify fungal particles or mold spores in collected air or surface samples. The results can provide useful information when investigating suspected indoor air quality concerns, visible staining, musty odours or moisture-related conditions.
