Radon Mitigation Photo Album: Basement & Crawlspace Mitigation in Boise, ID

Idaho Radon has partnered with this client for several years, providing annual radon testing services. Prior to our involvement, a crawlspace ventilation system had been installed by another contractor in an attempt to reduce radon levels. However, the system was insufficient, utilizing an undersized fan and failing to address depressurization beneath the basement slab. To effectively mitigate radon levels, Idaho Radon installed a sub-slab collection cavity and integrated venting through the crawlspace. A properly sized radon mitigation fanwas then installed to complete the system. As a result of these improvements, the average indoor radon concentration was successfully reduced from 3.5 pCi/L to 0.4 pCi/L.
