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.

In Cotopaxi, CO, a homeowner became concerned after discovering elevated radon levels in their home, particularly with a large 2,200 sq. ft. crawlspace that was encapsulated but not fully sealed to the foundation walls. They chose Purple Mountain Radon for their local expertise and proven experience handling complex crawlspace layouts. The team installed a gas mat, properly sealed the existing vapor barrier to the foundation walls, and connected the system to a depressurization setup—carefully addressing the two separate crawlspace chambers divided by a continuous footing to ensure consistent radon reduction throughout the home. The result was a safer, healthier indoor environment with radon levels brought under control. If you’re concerned about radon in your home, contact Purple Mountain Radon today and take the first step toward cleaner, safer air.
