I learned about the problem with radon gas pooling in basements last year and was shocked I had never heard of it before! I was even more surprised to learn that 16% of all lung cancer deaths in Canada are directly attributed to radon gas! My husband has a lot of cancer in his family and recently had an Aunt diagnosed with advanced stage lung cancer. She never smoked a day in her life. We want our home to be as healthy as possible for us and our young children. We bought a kit from Radon West to test our home over the winter (which Health Canada recommends ALL Canadians do). Our level was slightly higher than 200 Bq/m3 which is the level at which Health Canada recommends mitigation.
Karin, Colin and Renata at Radon West are absolute class acts. I have never encountered more professional, helpful and dedicated people. Every question I had was answered thoroughly, and most importantly, with the science to back it up. My husband and I decided to go ahead with the process of sub-slab depressurization which draws the radon gas out from the soil surrounding our foundation, stopping it from seeping into our basement and getting trapped there, accumulating to dangerous levels.
The installation process was meticulous and Colin and Renata left the area spotlessly clean after finishing. Our levels went from 211 Bq/m3 to 30 Bq/m3 after mitigation. I should also mention that I am EXTREMELY sensitive to vibration noise in my environment. Since there is a fan actively drawing air through the pipe at all times, there is slight vibration noise from the system. Colin visited the house on numerous occasions tweaking the installation until I was completely satisfied; not just willingly, but happily!
I can't recommend these guys highly enough. If only there were more contractors with this kind of integrity and dedication!
