We noticed a musty smell coming from the crawl space and tested for radon—levels were higher than the EPA action limit. We sealed all the vents and installed a sub-membrane depressurization system under the vapor barrier, which dropped the concentration from 6.8 pCi/L down to 1.2 pCi/L within a week. The plastic sheeting and fan setup cost around $900 and took an afternoon to install.

My radon alarm started chirping last week, and despite being a quiet little box on the basement wall, it got my full attention. It's easy to ignore the invisible gas, but that persistent beep reminded me radon is serious. I had to open windows and run a fan until levels dropped. Since then, I actually glance at it every morning—just to make sure.
