Radon Ottawa Gatineau is one of the only radon membrane specialists in Canada.

Radon Ottawa Gatineau sets the standard in encapsulation of exposed soil and rock outcroppings. Using fire rated ripstop membrane and closed cell spray foam to ensure a perfect seal.
What we do is called sub slab depressurization; it is the standard for a guaranteed reduction in Radon and any other soil gas contamination or infiltration into a building.
Radon Ottawa Gatineau only installs the best quality systems for the geographical location of the building. If you live in a sub zero climate, the heart of your system (the fan) will be located in the basement or heated part of the lowest floor. We use nothing but schedule 40 PVC pipe with chemically welded joints on our entire discharge pipe. All standard code compliant homes, with a 100% poured concrete floor also receive the same baseball bat proof pipe.

Reducing Radon Levels in Existing Homes: A Canadian Guide for Professional Contractors

Common sense has gotten us to this point and our work with Health Canada has helped to create a Radon installation guide that mimics our values.

The installation will vary from home to home. We guarantee to reduce your Radon gas levels to less than the world health standard of 100 Bq/m3.

No other company in any country gives you this kind of guarantee, let alone backs it up with the word “lifetime”, that’s right, our system designs and installations are guaranteed to reduce your Radon gas levels to 100 Bq/m3 for life. All fans installed by Radon Ottawa Gatineau have a 5 years replacement warranty as well.
