Before & After Photos

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.

Tucked into the hills of Bailey, CO, this home faced a unique radon challenge with dangerously high levels throughout multiple floors. With two unventilated crawlspaces and a basement showing extreme readings, the homeowners needed a customized solution. They chose Purple Mountain Radon for their expertise in complex mitigation designs. Instead of a single system, the layout required two separate ones to accommodate the structure without running pipes through their living space. Perforated piping was installed under vapor barriers in the crawlspaces, and suction points were strategically placed to optimize airflow. Just a day after installation, radon levels dropped to a safe range, giving the homeowners peace of mind. Every home is different—if you need a tailored solution for radon mitigation, trust the experts at Purple Mountain Radon.

Selling a home comes with many considerations, and for this homeowner in Bailey, CO, a high radon test result during the inspection meant a mitigation system was necessary. Referred by a satisfied neighbor, they trusted Purple Mountain Radon to get the job done right. To navigate the home's unique design, we installed a sub-slab depressurization system in the unfinished basement, carefully routing the venting next to the chimney to avoid the wraparound deck. With the system in place, the home is now ready for its next chapter. If you're preparing to sell your home, ensure radon isn’t a dealbreaker—Purple Mountain Radon is here to help!
