We are the CAA-recommended company in the industry.

Our story:
For over 20 years, we’ve been concerned with the quality of the air you breathe.
As a company specializing in structural decontamination, we first became interested in under-slab depressurization systems, because they greatly reduced soil decontamination problems, such as the presence of moisture in basements.
We did a lot of research on the subject and discovered that radon was a major air quality issue.
Our expertise:
So we decided to go one step further and add radon mitigation training to our expertise.
In 2009, we obtained American NEHA-NRPP training, followed by Canadian PNCR-C/C-CNRPP certification in 2012. In fact, we are virtually the only company to hold dual certification.
We operate with an RBQ license, a comprehensive insurance policy and have been a CAA-Quebec recommended company for several years.
Our experience:
For over 20 years, we have helped eliminate radon from thousands of properties across Quebec.

Radon is a sneaky and dangerous gas. It is colorless, odorless, and radioactive. It occurs naturally from the breakdown of radium and uranium found in the soil. Exposure to radon is the second leading cause of lung cancer after smoking. According to Health Canada, corrective action is recommended when radon levels exceed 200 Bq/m³. Only a test can confirm the level of radon in your home.
