Radon Testing & Mitigation in Cochrane

Onyx Radon · Cochrane, Alberta

Cochrane sits west of Calgary where the prairies rise toward the foothills and the Rockies, and its homes are as varied as its landscape — older houses in the established town, rural acreages, and fast-growing new communities on the hillsides. That variety matters for radon, because the uranium-bearing soils and bedrock common across this part of Alberta can produce elevated indoor levels in any kind of home. Testing is the only way to know yours.

Radon and Cochrane's mix of older homes and acreages

Cochrane's housing ranges from decades-old homes near the historic core to sprawling acreages and newer hillside developments in areas like Sunset Ridge and Heartland. Older homes may have foundation cracks and unsealed penetrations that let radon in, while acreages often sit directly on local bedrock. Newer builds are tightly sealed for efficiency. Each of these can hold radon for different reasons, so age and style alone won't tell you whether a given home is affected.

Radon is the leading cause of lung cancer in non-smokers and the second leading cause overall, linked to roughly 3,200 lung cancer deaths in Canada each year. Those numbers are why Health Canada recommends acting when a home tests above 200 Bq/m³. A long-term test of 90 days or more gives the truest reading through Cochrane's seasonal swings, and if levels are high, sub-slab depressurization is the proven way to bring them down.

FAQ · Radon in Cochrane

Cochrane radon questions

Are Cochrane acreages more likely to have radon?

Not necessarily more likely, but acreage homes often sit directly on local bedrock and rely on wells and rural foundations, so radon can enter through any opening to the ground. As across Alberta, the only way to know an acreage's level is to test it directly. A long-term 90-day measurement gives the most accurate picture for any rural Cochrane property.

My Cochrane home is older — does that change radon testing?

Older homes can have more foundation cracks, gaps and unsealed service penetrations, which give radon more ways in, but newer sealed homes can also trap it. Age alone doesn't predict the result either way. We test every home the same careful way to the C-NRPP standard, then recommend mitigation only if your level exceeds the 200 Bq/m³ guideline.

From a historic in-town home to a hillside new build or a rural acreage, Cochrane's variety is exactly why testing matters. We work to the C-NRPP standard and give you results you can trust.
