Living in west county, you might not think about radon until you hear from a neighbor who tested their basement. It's a silent, odorless gas that can seep from the ground into homes, and some areas here have higher levels than others. I picked up a simple test kit at the hardware store—took a few days, and the results gave me peace of mind. Worth checking if you haven't already.
