Fixing 17.5 pCi/L Radon in a Challenging Home With a Smart Two-Point System

Radon testing revealed levels of 17.5 pCi/L in this home, well above safe limits and requiring professional radon mitigation. With a complex roofline and a cluttered basement, careful planning was key. After coordinating cleanup before installation and duct cleaning, our radon contractor designed a two-point sub-slab extraction system in the back room, spaced 12 feet apart for effective radon reduction. The system connects high and exits through the side of the home using coring, meeting clearance requirements from windows and rooflines. We also sealed the sump pit and installed a 20x25 Breathe Easy air cleaner to improve indoor air quality and reduce radon exposure symptoms.
