"Radon mitigation system" has about 610 searches per month in Canada, difficulty 18. The site ranks around 55th<\/sup>. In French, it is called système d’atténuation: it does not filter indoor air, it prevents radon from the soil from entering.<\/p>
System components<\/h2>
- A suction point drilled into the slab, where air circulates under the concrete.<\/li>
- A pipe that runs up to the outside.<\/li>
- A fan, usually outside or in a location away from living spaces, that runs continuously.<\/li>
- An outlet that expels air far from windows.<\/li>
- An indicator on the pipe to show that suction is present. It does not measure radon.<\/li>
<\/ul>
The fan remains on at all times. Turning it off causes levels to rise. Electricity consumption depends on the model: it is not part of the installation price.<\/p>
Costs<\/h2>
The standard installation is $2,799.99 + taxes. The number of slabs, a sump pit, or a long pipe run can change the configuration. You receive the price before work begins. There is a 5% price guarantee under a written quote from a competitor for a comparable installation. The cost details<\/a> and the quote<\/a> are the two pages to consult.<\/p>
Before work, one key figure<\/h2>
The system is justified when a measurement exceeds 200 Bq\/m³. The 91-day test<\/a> is the reference. The 4-day test is used for quicker screening. After work, a new measurement verifies the reduction. The pipe indicator only verifies that the fan is drawing air.<\/p>
