Radon testing in Québec City: what matters here

Older homes often have cracked foundations, incomplete slabs or open sumps, all entry routes for radon. A long-term test is all the more relevant.

The masonry walls of older homes, insulated after the fact, and the capital's long winters make condensation a frequent finding. Thermography helps locate the cold areas where moisture builds up.

Radon testing: what the inspector checks in Québec City

The detector goes on the lowest lived-in level, where people spend at least a few hours a day: a finished basement, for example. An unfinished basement where nobody spends time isn't the target of the measurement.

Québec City's long winters make the attic a risk area: the inspector looks for condensation under the roof deck, ice along the eaves and bathroom fans venting directly into it.

Report, timing and booking: Radon testing in Québec City

Dry summers are when clay-related settlement shows most: a crack that opens in August deserves monitoring.
