Why Homes in Toronto Need Measurement, Not Guesswork
Toronto homes and buildings present a wide variety of indoor air quality conditions. Older properties often include basements, additions, and multiple layers of renovation that can affect how radon accumulates, how VOCs off-gas, and how ventilation performs. Newer or recently renovated properties that have been made more airtight can accumulate higher concentrations of indoor pollutants if ventilation is not balanced.
Lower-floor units and basement living areas in particular can have different radon exposure levels compared to upper floors. This does not mean elevated radon is guaranteed in any specific building — it means testing is the only way to know what is actually present.
RBM Group serves Toronto on a mobile, on-site basis. RBM does not have a Toronto office, but travels to your property, conducts professional diagnostics, and delivers written findings. Every recommendation is based on what the measurements show at your specific address.
