Radon Mitigation Before & After Photos

This cabin in Como had a sub-slab depressurization system installed in the mechanical room.

Radon is a naturally occurring gas that can accumulate in homes, posing serious health risks over time, especially when levels exceed recommended limits. In this case, the radon level in the basement was dangerously high at over 9.0 pCi/L, affecting the safety of the home's occupants, including the son’s bedroom. Purple Mountain Radon was called in to address this issue, as the home, built into the side of a mountain, had no initial mitigation measures, with the slab poured directly onto solid granite. Due to the challenges posed by the granite, including potential fissures, a more complex solution was avoided by installing an ERV system, which effectively reduced radon levels without extensive excavation. This proactive step ensured the family’s safety without unnecessary delays or costs. If you’re concerned about radon in your home, don’t wait—contact us today to discuss your mitigation options!
