Mould Testing & Indoor Air Quality
Properties across Vancouver Island, especially in high-humidity areas like Victoria, Nanaimo, and coastal communities, are particularly susceptible to indoor mould growth. Moisture from leaky roofs, poor ventilation, plumbing issues, or past flooding can create the perfect environment for hidden mould to thrive—posing serious concerns for building safety, air quality, and long-term property damage.
Building authorities recommend annual mould inspections and professional testing to support safe living and working environments.

What Is Mould?
Mould is a type of fungus that thrives in damp, humid environments. It reproduces through microscopic spores that travel through the air and can settle on virtually any surface. Once established, mould can grow rapidly—especially in areas with moisture problems, poor ventilation, or water damage.
Mould comes in many forms, including common types like Cladosporium, Penicillium, Aspergillus, and the notorious Stachybotrys chartarum (black mould). While not all mould is harmful, some types can pose serious health risks, especially to individuals with allergies, asthma, or weakened immune systems.
Health Risks Associated with Mould Exposure
Exposure to mould spores can affect people differently depending on the type of mould, the length of exposure, and individual sensitivities. Common health effects include:
Addressing mould early can prevent these health concerns and reduce the risk of long-term structural damage to your property.
Mould on Vancouver Island
Vancouver Island’s coastal climate—marked by high rainfall, humidity, and damp conditions—creates an ideal environment for mould growth. Older buildings in cities like Victoria, Nanaimo, Courtenay, and Campbell River are particularly vulnerable, especially if they suffer from water intrusion, roof leaks, or poor ventilation.
Common Areas for Mould Growth Include:
🚿 Bathrooms and Kitchens
Frequent steam, spills, and poor ventilation make these moisture-rich areas hotspots for mould growth.🏚️ Crawl Spaces and Basements
Dark, damp, and often poorly ventilated—ideal conditions for hidden mould colonies.
🏠 Attics and Rooflines
Roof leaks and poor airflow can lead to unnoticed mould buildup in upper levels.
🪟 Windows
Condensation around windows can cause moisture accumulation and mould on sills and frames.
🚰 Plumbing Fixtures
Leaks under sinks or behind walls provide the moisture mould needed to thrive.
🌀 HVAC Systems
Ventilation ducts and AC units can harbour moisture and spread mould spores throughout the property.
Professional inspections are essential because mould can remain hidden behind walls, under flooring, or within insulation, especially if you suspect water damage. Health authorities recommend prompt testing and remediation when mould is suspected. Professional testing can identify the type and extent of mould contamination, guiding the safe removal process.
Whether you're ensuring regulatory compliance or mitigating potential risks, Phase Environmental provides:
Why Mould Inspections and Testing is Important
Inspections and testing are a reliable way to confirm the presence, type, and extent of mold contamination in a building. Early detection helps prevent serious health issues and costly property damage.
Our certified inspectors follow industry-approved protocols to collect air and surface samples, which are analyzed using laboratory methods such as spore trap analysis and culturing techniques. We provide detailed, actionable reports that meet industry standards and support compliance.
Mould Regulations and Guidelines in British Columbia
While mould is not regulated in the same manner as asbestos, WorkSafeBC and Health Canada recognize the health hazards of indoor mould exposure and have issued strict guidelines for identifying and controlling it, especially in occupational settings.
Health and Safety Regulations require employers, property managers, and contractors to assess and address indoor air quality complaints and prevent worker exposure to bioaerosols, including mould. Failure to follow these guidelines can result in stop-work orders and penalties.
Protective Measures and Recommendations
Ensure Safety & Avoid Costly Penalties
Neglecting mould risks or failing to comply with health and safety regulations can lead to the following:
⏳ Project Delays and Shutdowns
Undetected mould can halt construction, delay permits, and require additional inspections or remediation before work resumes.
⚖️ Legal Penalties and Compliance Issues
Non-compliance with WorkSafeBC guidelines may result in fines, stop-work orders, and potential liability.
💸Costly Cleanup and Remediation
Unaddressed mould issues often lead to structural damage, expensive containment, and specialized remediation costs.
