Indoor Air Pollutants That Affect GTA Homes
Many dangerous indoor air pollutants are invisible and odourless. Professional testing is the only way to accurately measure exposure levels and protect your family's health.
Mold Spores
Invisible mold spores circulate through HVAC systems and cause respiratory issues, allergic reactions, and asthma attacks. Professional air sampling identifies mold species and concentration levels.
Asbestos Fibres
Disturbed asbestos-containing materials release microscopic fibres that remain airborne for hours. Air clearance testing after abatement is required by Ontario law.
VOCs (Volatile Organic Compounds)
Off-gassing from building materials, paints, adhesives, and cleaning products. Elevated VOC levels cause headaches, nausea, and long-term health effects.
Carbon Monoxide
Odourless and colourless, CO from faulty furnaces, fireplaces, and attached garages is a leading cause of accidental poisoning deaths in Ontario homes.
Radon Gas
The second leading cause of lung cancer in Canada. Radon seeps from soil and rock into basements. Health Canada recommends testing all Canadian homes.
Particulate Matter (PM2.5)
Fine particles from combustion, renovation dust, and outdoor pollution penetrate deep into lungs. Post-renovation air testing confirms safe levels before re-occupancy.
Health Canada Recommendation: All Canadian homes should be tested for radon.[1] The Greater Toronto Area has documented areas of elevated radon potential. Long-term radon exposure is the second leading cause of lung cancer in Canada, responsible for approximately 3,200 deaths per year.
From Testing to Clearance — A Complete Air Quality Solution
Initial Consultation & Site Assessment
Our certified industrial hygienists conduct a visual inspection of your property, review occupant health complaints, and identify potential sources of indoor air quality problems.
Air Sampling & Testing
Calibrated air sampling equipment collects air samples for laboratory analysis. We test for mold spores, asbestos fibres, VOCs, radon, CO, particulate matter, and other pollutants specific to your concerns.
Laboratory Analysis
Samples are analyzed by accredited Ontario laboratories. Results are typically available within 24–72 hours for standard testing and same-day for emergency situations.
Detailed Report & Recommendations
You receive a comprehensive written report with pollutant levels, comparison to Health Canada and Ontario guidelines, identified sources, and a prioritized remediation plan.
Remediation & Source Control
If testing identifies problems, our certified technicians address the source — mold remediation, asbestos abatement, HVAC cleaning, ventilation improvements, or radon mitigation.
Post-Remediation Clearance Testing
After remediation, clearance air testing confirms pollutant levels have returned to safe levels. You receive a written clearance certificate for your records and insurance.
"Radon is the invisible risk that most GTA homeowners don't think about. It's odourless, colourless, and the second leading cause of lung cancer in Canada. A $200 test kit from Health Canada or a professional short-term test from us takes 48 hours. There's no excuse not to test your basement."
