Thorough and Professional Job

Radon Controls Inc is a very professional company specializing in radon control, as the name suggests. They got my radon levels down from ~200 to ~15, so we're very pleased. They were friendly, helpful, professional, transparent, and thorough. I'd highly recommend them to anyone. ~ S. McCarthy

Professional and Certified Radon Testing and Mitigation Solutions

Radon Controls was co-founded in 2009 by Len Gieck and Pat Lagore. We started with the intention of helping people navigate testing for radon and radon remediation in a way that made them feel assured and fully informed through the process. We strive for openness, clarity, honesty and fair pricing while still maintaining the highest standards of professionalism and the most up to date scientific approach to each and every project. 

Our Story

Radon Controls Inc. is the first radon focused company in Alberta, founded in 2009. We realized that householders were anxious as they were concerned about radon in their homes, but couldn't find any reliable, trustworthy information specific to Canada. From the beginning, our goal has been to address the fear by providing credible information coupled with sound, scientific and proven solutions. 

In 2007, Len learned of the dangers of radon gas and that it was the leading cause of lung cancer in non-smokers. He tested his home and discovered the radon levels were at a very unsafe level - over 300 bq/m3 (more than triple the acceptable World Health Organization level). With a daughter living in the basement of his home, he was deeply concerned and set out to find a solution.

Neither the federal nor the provincial governments were able to offer solutions at that time.

As a Master Builder, Len was able to conduct his own research and install a mitigation system, subsequently reducing the radon levels in his home to a safer level. As a builder, he wanted to share this benefit with his buyers and began to rough-in radon systems into his new homes almost a decade before it became a requirement in the building code.

Len and Pat each originally received certification in the US, and subsequently in Canada once protocols were established here, and certification became available.
