Radon Mitigation System

Radon Mitigation

Homeowners with a concentration of radon higher than 200 Bq/m³ should take corrective measures with a certified radon mitigation contractor. The Quebec Lung Association estimates that nearly 20% of houses in Quebec have a concentration of radon higher than 200 Bq/m3 (Journal de Montréal 2021). This threshold established by Health Canada is the measure over which radon becomes of risk for human health.


Depending on the type of construction, building owners with a dangerous concentration of radon should invest in a system to mitigate radon and attenuate its effects on pulmonary health. Installing a radon mitigation system is a small investment to protect yourself against radon.


Our certified C-NRPP program professionals have the training and experience to ensure that the system has the least possible impact on home heating and cooling costs and that they will be efficient for the entire floor space of your property.


All radon mitigation systems installed by Radon XPro reduced radon levels to lower than 50 Bq/m3. Our certified radon mitigation professionals ensure that the radon mitigation system in place reflects the latest approaches and techniques of the industry. A poorly designed or installed mitigation system can have serious repercussions on a home’s energy costs and on your health. Make sure you ask a C-NRPP specialist.

What Options Does Radon XPro Offer to Mitigate Radon?

Sub-slab depressurisation (SSD)

The SSD technique is the most common technique for radon mitigation in residential homes. If you are looking for a simple and cheap radon mitigation solution, the sub-slab depressurisation is probably your best option.  Your home must have a slab floor.


PVC piping is installed through the slab and connects with a radon fan to vacuum radon and all other gases present under the basement slab outside the house. When these systems are meticulously designed and installed, they significantly reduce the radon levels in a home.


Sub-membrane depressurisation (SMD)

We use this technique when a home has exposed dirt or rock in a crawl space instead of a basement. Using this approach, the radon is extracted under a polyethylene film placed to cover the exposed surface and connected to a fan drawing the air from beneath the membrane. This type of system is more complex and takes longer to install therefore can be more expensive than the SSD but works just as effectively.


Radon Mitigation Parts

Radon XPro also offers a parts service of radon mitigation systems. If you are a contractor and are looking to install this type of system in a new construction or on an existing property, we have different types of ventilators and all the material you need.

What is a Radon Mitigation System and How Does it Work?

In a few words, a radon mitigation system is installed to reduce radon levels in an existing home or is installed as a preventive measure in new constructions. It is composed of a piping system that connects to a fan that extracts radon outside

What level of radon requires mitigation?

According to Health Canada’s recommendations, if radon levels are higher than 200 Bq/m3, you should take action to install a radon mitigation system. However, the World’s Health Organisation (WHO) has decreed that radon levels higher than 100 Bq/m3 should be taken care of by the owner if they have the capacity to do so since radon still poses a risk to health at that level (WHO 2022).

Do I need radon mitigation?

To know if you need a radon mitigation system, you must measure the radon levels in your home first. If you have radon levels higher than 200 Bq/m3, you should take action to install a radon mitigation system according to Health Canada (Health Canada 2021).

Is a radon mitigation system necessary?

Once you’ve completed radon testing and have your measurement report, you should evaluate if you are comfortable with the level of radon in your home. You may follow the threshold given by the federal government of Canada set at 200 Bq/m3 or the WHO threshold set at 100 Bq/m3. It is up to the homeowners to evaluate what is the level of radon that they are comfortable to live with.

How much does a radon mitigation system cost?

The price for a radon mitigation system is comparable to installing an air conditioning unit. The rough price range of a radon mitigation system is from $3000 to $5000.
