Indoor Air Quality Testing in Ottawa & Eastern Ontario

The air inside your Ottawa home can be significantly more polluted than the air outside — and unlike outdoor air quality, it's something you have direct control over. Indoor air quality issues are linked to respiratory problems, allergies, headaches, fatigue, and in serious cases, long-term health consequences.

Property Inspection Network's certified inspectors provide comprehensive indoor air quality assessments for Ottawa homes and properties throughout Eastern Ontario. Whether you're concerned about mold, VOCs, or general air quality, we give you the data and the answers you need.

What We Test For

Mold & Mold Spores

Mold releases microscopic spores into the air that can cause or worsen respiratory conditions, allergies, and asthma. Air sampling detects elevated spore counts even before visible mold appears. We compare indoor samples to an outdoor baseline to identify whether your home has an abnormal mold burden.

Volatile Organic Compounds (VOCs)

VOCs are chemicals emitted by paints, adhesives, flooring, cleaning products, furniture, and building materials. In poorly ventilated homes, VOC levels can build up to concentrations that cause headaches, dizziness, and irritation. New construction and recently renovated homes are particularly susceptible.

Carbon Monoxide (CO)

Carbon monoxide is an odourless, colourless gas produced by combustion appliances — furnaces, water heaters, fireplaces, and attached garages. Our inspection includes a CO assessment as part of a comprehensive air quality review.

Humidity & Moisture Levels

Excessive indoor humidity (above 50–60%) creates conditions that support mold growth, dust mite populations, and structural moisture damage. We measure relative humidity throughout the home and identify areas where moisture control is needed.

Signs of an Indoor Air Quality Problem

Musty or chemical odours that linger regardless of cleaning
Family members experiencing frequent headaches, fatigue, or eye/nose/throat irritation
Worsening allergies or asthma symptoms when at home
Condensation on windows or visible moisture on walls

Visible mold growth anywhere in the home
Home was recently renovated, new carpet installed, or new furniture added
Older home with unknown insulation or building materials (asbestos risk era: pre-1990)
Furnace or water heater has not been serviced recently

Indoor Air Quality Testing for Home Buyers

Air quality is increasingly on the radar of Ottawa home buyers — particularly for homes with basements, older HVAC systems, or evidence of past water damage. A pre-purchase air quality test gives you objective data about what you're breathing before you commit to the purchase.

Our inspectors can perform air quality testing as a standalone service or as an add-on to your home inspection, with results included in a single comprehensive report.

Indoor Air Quality Testing for Homeowners

You don't need to be buying or selling to benefit from air quality testing. If you or a family member has unexplained health symptoms, if you've recently made significant renovations, or if your home simply smells off, a professional air quality assessment is the fastest way to identify and address the issue.

Many Ottawa homeowners also test after mold remediation to confirm the work was effective and spore levels have returned to normal.

Ottawa's Unique Air Quality Considerations

Ottawa's climate and housing stock create specific indoor air quality risks:

Older homes

Many Ottawa homes built before 1980 may contain asbestos-containing materials (insulation, floor tiles, ceiling texture) that release fibres if disturbed

Basements

Ottawa's clay-heavy soil creates high hydrostatic pressure and basement moisture, which drives mold growth

Winter airtightness

Ottawa's cold winters mean homes are sealed tight for 4–6 months per year, allowing pollutants to accumulate

New construction

Off-gassing from building materials, adhesives, and finishes can affect air quality in newly built or recently renovated homes

What to Expect During Your Air Quality Inspection

Your inspector will conduct a thorough walk-through of the home, collecting measurements and observations across all major areas. Air samples are sent to an accredited laboratory for analysis (where applicable), and you receive a written report with all results, interpretation, and recommended next steps.

Timeline: most air quality reports are delivered within 3–5 business days of the inspection. Rush turnaround is available for real estate transactions.

A mold inspection focuses on identifying visible mold and moisture sources. Air quality testing is broader — it uses air sampling to detect airborne contaminants including mold spores, even before visible mold appears.
We recommend it when: buying an older home with basement concerns, after water damage or mold remediation, when family members experience unexplained health symptoms, or before taking occupancy of a newly renovated space.
