Mold Inspection & Testing Calgary

A CHI mold inspection follows the process recommended by Canada Mortgage and Housing Corporation (CMHC). We start with a background investigation — history of flooding, roof or plumbing leaks, and any occupant health symptoms. We then conduct a full visual inspection for visible mold, moisture staining, and musty odours. Where mold is suspected but not visible, we collect air samples using professional equipment and send them to an accredited local laboratory for analysis. You receive a written report with findings, lab results where applicable, and recommended next steps.

A standard home inspection looks for visible signs of moisture damage and conditions that could lead to mold — but it is not a dedicated mold inspection. At CHI, we include thermal imaging on every standard inspection which helps identify hidden moisture that may indicate mold risk. If mold is suspected during a standard inspection, we recommend booking a dedicated mold investigation with air sampling for definitive results.

You should consider a mold inspection if you notice musty or earthy odours in any area of your home, visible dark staining on walls, ceilings, or grout, unexplained allergy or respiratory symptoms in occupants, a history of water damage, flooding, or roof leaks, or if you are buying or selling a home and want documented confirmation of mold-free air quality. Calgary’s climate — with significant freeze-thaw cycles and ice damming — creates specific moisture risks that make mold more common here than in milder regions.

A home inspection does not pass or fail a property — it identifies and documents conditions. If significant mold growth is found during a home inspection or dedicated mold investigation, it will be documented in the report with photos and context. What you do with that information — negotiate a price reduction, request remediation, or walk away — is your decision. The report gives you the evidence to act from a position of knowledge rather than uncertainty.

A typical mold inspection takes 1 to 3+ hours on-site depending on the size of the property and the extent of suspected mold activity. Larger homes, finished basements, and properties with a history of water damage require more time. Air samples are collected during the visit and sent to an accredited laboratory — lab results typically take 3 to 5 business days. Your written report with findings and lab results is delivered once analysis is complete.
