Radon testing in Granby: what matters here

Even in the city, on filled land, radon can be present. A low result in the neighbouring building doesn't apply to your home.

Downtown brick houses, insulated in different ways over time, often have thermal bridges. Thermography helps target the work without redoing all the insulation.

Radon testing: what the inspector checks in Granby

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.

In downtown Granby's brick houses, the inspector uses thermography to find thermal bridges at lintels and floors. They also measure moisture at the bottom of walls insulated from inside.

Report, timing and booking: Radon testing in Granby

For an older home, gather renovation invoices and permits before the inspection: they help separate what was redone from what is original.
