What Does An Environmental or Indoor Air Quality Assessment Actually Check For?

Posted in Air Quality, on September 25, 2026

Environmental testing in Toronto can provide valuable information on your home air quality so that you can make changes that can positively affect your health and indoor comfort. SafeAir has helped hundreds of clients use indoor air quality testing to check for common pollutants and make changes that promote healthier living. We offer generalized environmental tests as well as targeted services like mold testing and radon testing. Here's how our team can help.

What an Environmental Assessment Covers

Environmental testing offers a global, zoomed-out view of your home's indoor environment. We may test for factors like humidity or airflow, and pay attention to small clues or evidence of issues like mold growth or specific pollutants.

Common Issues That Prompt Indoor Air Quality Testing

When should you book air quality testing? At SafeAir, we suggest our clients book a home air quality assessment whenever there is a major change (like a move, new family member, or renovation) or when you notice signs and symptoms of poor air quality. Common signs include:

• Strange or musty odours.
• High indoor humidity.
• An increase in dust or debris.
• Unusual allergies or health effects.
• Mold growth.

Mold and Radon Testing

Two of the specialized tests SafeAir offers are mold testing and radon testing. These are specialized services that can run concurrently with environmental testing in Toronto or as a stand-alone service.

Mold testing looks for the presence of mold spores and offers insight into what type affects your home. Mold creates airborne spores that negatively affect home air quality and can cause allergies and physical damage.

Radon gas, meanwhile, is a colourless, odourless gas produced by the environment. Radon exposure causes cellular damage to the lungs that leads to the development of lung cancer, making it essential to test for. You can read more about radon testing in Toronto in our article here.
