Radon Mitigation Before & After Photos

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!

A home in Westcliffe, CO, presented a unique challenge for radon mitigation due to a new addition with two separate foundations and in-floor radiant heating beneath ceramic tile flooring. The homeowner, already familiar with radon mitigation from their Trinidad property, wanted a solution that didn’t require coring through the finished floors. After evaluating options, Purple Mountain Radon first proposed an ERV system, but limited space in the mechanical room made installation impractical. Instead, the team carefully cored through the foundation walls just below grade on the exterior, connecting piping to create an effective sub-slab depressurization system. Now, the home benefits from a properly designed mitigation system, reducing radon levels without disrupting the radiant flooring.

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

When new homeowners moved into their Lake George, CO home, they discovered radon levels at 5 pCi/L, with a significant source being the unsealed crawlspace. To address this, Purple Mountain Radon implemented a sub-membrane depressurization system. The process included installing a gas mat on the crawlspace floor, encapsulating the space with a durable 6.5 mil vapor barrier, and mechanically fastening it to prevent tears. The barrier was securely sealed to the walls, creating an airtight space, and a radon suction point was installed at the exterior rim joist. The result was a significant reduction in radon exposure, giving the new homeowners peace of mind.
