Downtown Toronto radon testing and mitigation

Depends on your floor. Radon is heaviest at ground level because it enters from the soil. Units on floors 1 to 3 can have meaningful exposure, especially if there is a parking garage or service shaft directly below. By floor 4 levels are typically already 80 percent diluted; by floor 10+ exposure is negligible. If you live on the 2nd floor of an older mid-rise with garage adjacency, testing is worthwhile. If you live on the 25th floor of a glass tower, do not bother.

Pre-war on average. Many Annex, Cabbagetown, Riverdale, Roncesvalles, and Junction homes have stone or rubble foundations, dirt-floor sub-basements, and decades of accumulated foundation cracks. These conditions favour radon entry. The older the home and the more finished basement living space, the more important testing becomes.

Yes. The downtown Toronto core (Yonge corridor, Queen West, Annex, Cabbagetown, Riverdale, Roncesvalles, Bloor West, Junction, Christie Pits, and the area west of the Don Valley) is fully within our service area. Same $99 testing price as suburban GTA, no distance surcharge. The lack of dedicated downtown Toronto C-NRPP testers in the public directory is exactly why we serve the area.

Yes. Basement apartment tenants in older Toronto homes have some of the highest radon exposure profiles in the GTA: ground-level living, often older foundations, often poorly ventilated, and you spend most of your indoor time there. As a tenant you can run a long-term DIY kit ($30 to $60) without landlord involvement. If the result is high, the test report makes a remediation request much harder for the landlord to ignore.
