We recently completed a radon mitigation system installation in a 1922-built colonial home in Fairfield, CT with a fieldstone foundation, unfinished basement, and a radon level of 6.0 pCi/L. With no sump pump and no prior mitigation system, we designed a discreet and effective one-pipe system suited for the home’s layout and age. Access was through the side door leading directly to the basement, ensuring minimal disruption.
