Im still having Radon problems here. There are a few areas between the flooring and the trim where there are gaps like this -
Im guess I have to chaulk everywhere where the trim meets the sheetrock...but not sure what to do for the above image where the trim meets the flooring?
I have the same radon levels that I had before the flooring was installed. (7.0 ) This is a bummer.
They used radon plastic and padding as well with the 1/2 inch thick laminate flooring. This gas is impossible to get arid of. The readings in the crawl space were low too.
