Indoor Air Quality

Important information

Phase Environmental provides certified indoor air quality (IAQ) testing across Vancouver Island. We help property owners, employers, and facility managers detect and resolve airborne hazards in homes, workplaces, schools, and public buildings.

We work closely with building managers, safety officers, contractors, and restoration teams to ensure indoor environments are safe, healthy, and compliant—whether you're responding to complaints, verifying post-remediation results, or meeting WorkSafeBC requirements.

All testing is performed using calibrated equipment and analyzed by accredited laboratories. You'll receive a detailed, defensible report with clear next steps and recommendations.

✅ What We Test For

Our indoor air quality services include:

✔️ Mould spore testing (airborne and surface swab analysis)

✔️ VOC monitoring for off-gassed chemicals like formaldehyde and benzene

✔️ Particulate matter (PM2.5, PM10) testing for dust, smoke, and debris

✔️ Carbon monoxide (CO) and carbon dioxide (CO₂) level assessments

✔️ Post-remediation clearance testing and reporting

✔️ More, ask us!

We can test for:

Mould in Air Testing and Surface Analysis

Mould thrives in damp or poorly ventilated areas like basements, attics, bathrooms, and flood-affected spaces. As it grows, it releases airborne spores that can trigger allergies, asthma, and other respiratory symptoms.

We provide:

✔️ Air testing to measure mould spore levels

✔️ Surface swab or tape-lift sampling

✔️ Reporting for insurance claims, remediation verification, and tenant concerns

Ideal for:

✔️ Initial assessments where mould is suspected

✔️ Clearance testing after remediation

✔️ Ongoing IAQ monitoring in high-risk facilities (schools, rentals, healthcare)

VOC (Volatile Organic Compounds) Testing

VOCs are airborne gases released by paints, adhesives, furnishings, and cleaning products. When ventilation is poor, VOC levels can build up and cause symptoms like headaches, fatigue, or respiratory irritation.

VOC testing is recommended for:

✔️ Renovations or new construction using synthetic materials

✔️ Occupant health complaints

✔️ Post-abatement verification

We test for compounds like formaldehyde, benzene, toluene, and xylene, helping you identify sources and take action.

Particulate Matter (PM) Testing

Particulate matter refers to airborne dust, soot, smoke, and debris. Fine particles (PM2.5 and PM10) can enter the lungs and affect breathing, especially in high-exposure environments.

We monitor PM levels during:

✔️ Construction or demolition

✔️ Dust-generating work in occupied buildings

✔️ Indoor air quality complaint investigations

Results help verify the effectiveness of dust control measures and support regulatory documentation.

Carbon Monoxide (CO) & Carbon Dioxide (CO₂) Testing

CO and CO₂ levels are key indicators of indoor air safety and ventilation. CO is a dangerous gas from fuel-burning appliances; CO₂ builds up when there’s not enough fresh air.

We assess CO and CO₂ levels in spaces like offices, schools, apartment buildings, and industrial areas to identify:

✔️ Poor ventilation

✔️ Appliance-related CO risks

✔️ Conditions that make people feel tired, dizzy, or unwell

WorkSafeBC requires indoor air quality to be evaluated if your building has had complaints, renovations, or ventilation changes.

Clear, Defensible Reporting

All findings are documented in reports that are:

✔️ WorkSafeBC-compliant

✔️ Suitable for insurance and health audits

✔️ Easy to understand and act on

✔️ Delivered quickly for peace of mind
