Hi Val,

Since I finished the radon mitigation system in my home, the radon level is consistently about 1 pCi/L.

I wanted to say thank you for posting and maintaining the DIY mitigation information on your website. Knowing very little about radon mitigation before I started researching in January 2014, the information you have posted has made this project a success.
