Mould & Moisture Diagnostics

Professional assessment of mould presence, moisture intrusion, and conditions conducive to fungal growth in residential and commercial buildings.

Understanding Mould in Buildings

Mould is ubiquitous in the environment, but active mould growth indoors indicates moisture problems requiring attention. Mould colonies release spores and metabolic byproducts (including mycotoxins in some species) that can affect indoor air quality and occupant health, particularly for sensitized individuals.

Mould requires moisture to grow—relative humidity above 70% or direct water contact enables colonization of building materials. The key to mould management is moisture control. Our diagnostics focus on identifying moisture sources and pathways, not just visible mould growth.

Moisture: The Root Cause

Mould growth is always a moisture problem. Whether from roof leaks, plumbing failures, condensation, rising damp, or inadequate ventilation—identifying and eliminating the moisture source is essential. Cleaning mould without addressing moisture ensures recurrence.

Our Assessment Includes

Visual inspection for mould growth and water damage
Moisture mapping with professional meters
Thermal imaging to detect hidden moisture
Relative humidity and dew point analysis
Identification of moisture sources
Assessment of HVAC and ventilation
Building envelope evaluation
Recommendations for remediation

Health Considerations

Mould exposure can cause a range of health effects, primarily in sensitized individuals. While mould affects people differently, common symptoms associated with mould exposure include:

Allergic reactions (sneezing, runny nose, red eyes)
Asthma attacks and respiratory symptoms
Chronic sinusitis
Skin irritation
Fatigue and cognitive effects
Immune system impacts
Mycotoxin exposure concerns
Sensitivity development over time

Remediation Guidance

We provide diagnostic assessment and recommendations—we do not perform mould remediation. This separation ensures our assessments remain objective. We can recommend qualified remediation contractors and provide post-remediation verification if required.
