Radon Mitigation Photo Album: Crawlspace Encapsulation in Idaho City, ID

The project commenced in the latter half of 2024 with radon testing conducted in one of the five buildings at Shadow Mountain Apartments in Idaho City. Following initial resident-conducted testing, the scope was expanded to include all five buildings to verify the findings. The results confirmed that each building exhibited elevated radon levels exceeding 4.0 pCi/L.   To address this issue, a dedicated mitigation system was installed for each building, incorporating a 6-mil vapor barrier. Fans were strategically positioned at the rear corners of the buildings to minimize both visual and auditory impact.     The project was successfully completed within 2.5 days by a two-person team. During the installation process, management was also informed of observed water leaks and structural concerns. Electrical connections for the fans were performed by a qualified electrician hired by the client.
