Radon testing in Mascouche: what matters here

In Mascouche, this inspection takes the local context into account, especially pyrite in the fill under slabs. The inspector adapts the examination to that context, and the report clearly states what it means for the property and which additional checks could be useful.

In new homes, construction moisture sometimes takes several months to dissipate. Condensation on windows and damp odours in the first year call for checking ventilation and the air exchanger.

Radon testing: what the inspector checks in Mascouche

Health Canada recommends measuring radon for at least three months, ideally during the cold season, when the house is closed up and radon builds up more. A measurement lasting a few days only gives an indication.

The inspector checks that the air exchanger works and is properly adjusted, then looks for condensation on windows and in the attic. In a new Mascouche house, that's often where the first moisture problems show up.
