This 1920 colonial-style home in Hamden, CT tested at a radon level of 4.0 pCi/L. With a cinder block foundation layered with brick, no sump pump, no crawl spaces, and no visible cracks, our team installed a simple and effective one-pipe radon mitigation system. We accessed the home via the Bilco door, with the fence gate located on the right side of the house. No additional piping or encapsulation was needed—just clean, streamlined work to reduce radon safely.
