Idaho Radon Before & After Photos

This 1,800 sq. ft. basement required the installation of two active soil depressurization systems due to load-bearing footers that limited the ability to achieve adequate sub-slab suction with a single system. One system was installed on the north side of the home and discreetly concealed behind built-in shelving, while the second system was located in a storage room and routed through a crawlspace to a fan mounted on the exterior wall. Idaho Radon successfully reduced the average radon level to 1.3 pCi/L.

Idaho Radon installed an active depressurization system for a residence in Idaho City.  Attached are a before and after picture of the exterior of the system.

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.
