Before & After Photos

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.
