Moisture, mould and water intrusion: begin with evidence, not assumptions.
A stain, odour or deteriorated material confirms that a condition deserves attention. It does not always reveal origin, extent or current activity by itself.
A useful recommendation addresses the moisture source and the extent of affected materials. Cleaning a surface without correcting water or vapour entry often leads to recurrence.
Three essential questions
What is the possible source: rain, plumbing, ground moisture, condensation or a past event?
Does the condition appear active at the time of inspection?
Which materials and spaces may be affected beyond what is visible?
Measure without overinterpreting
A moisture meter compares materials and helps locate areas requiring attention. Readings depend on material, instrument and conditions. A dry reading today does not erase evidence of a previous event.
Visible mould or odour
Health Canada recommends correcting moisture sources and cleaning affected surfaces according to extent and material. Significant, recurring or concealed contamination may require a qualified resource.
When to open or test
A general inspection is non-destructive. Exploratory openings, sampling or specialist investigation are appropriate when potential consequences and observed evidence exceed what can be concluded visually.
