Air Quality Testing Saint-Jérôme
Indoor air quality testing: radon, mold, VOCs, and humidity, with lab analysis.
In Saint-Jérôme, part of the North Shore / Laurentians area, our certified inspectors and engineers deliver this service directly to local owners, buyers, and condo boards — with the same rigorous process and detailed reporting offered across Greater Montreal.
The air you breathe at home or at the office can contain invisible contaminants — mold, volatile organic compounds (VOCs), radon, fine particles — without any obvious warning sign. Indoor air quality testing precisely measures what you're breathing and identifies pollution sources before they affect your health or your property.
Radar Inspection performs air quality testing in Montreal for residential properties, rental buildings, and commercial buildings.

What the service includes
- Mold — grows in damp areas (basements, windows, poorly insulated walls) and releases allergenic spores
- Radon — a naturally occurring radioactive gas that seeps in through foundations
- Volatile organic compounds (VOCs) — found in adhesives, paints, melamine furniture, and cleaning products
- Excessive or insufficient relative humidity — above 50% promotes mold and dust mites, below 30% causes dryness and irritation
- Fine particles and allergens — dust, pet dander, dust mites
- Combustion gases — including carbon monoxide, in homes with combustion appliances
Why Indoor Air Quality Is a Serious Issue in Quebec
In Quebec, we spend much of the year indoors, in well-insulated, poorly ventilated buildings — ideal conditions for moisture and contaminants to accumulate. According to the Institut national de santé publique du Québec (INSPQ), moisture control and adequate ventilation are central to good indoor air quality, as is radon screening on the lowest occupied floor of the home.
Radon, a naturally occurring, colorless, odorless radioactive gas, seeps in through foundation cracks and is the second leading cause of lung cancer after smoking. Some regions of Quebec, including the Laurentians, the Eastern Townships, and Montérégie, have naturally higher concentrations — a good reason to check, no matter where your property is located.
- Frequent headaches or respiratory irritation
- Persistent musty odors, even after cleaning
- Excessive condensation on windows
- Allergies or respiratory symptoms that improve when you leave the building
- Moisture stains, efflorescence, or visible signs of mold
