Radon Mitigation for a Three-Chamber Home with an Inaccessible Crawlspace

A home with three separate chambers and an inaccessible crawlspace required a carefully planned radon mitigation approach. To address the challenging layout, an opening will be created between the first and second chambers, allowing the system to reach the areas that need attention. Multiple extraction points will be positioned throughout the home, with the system exiting near the northwest corner. An ERV will also be installed in that area to support improved ventilation, with nearby power access helping simplify installation. The Sedona unit will be positioned near the drain. Despite the added complexity of the project, the homeowners were understanding of the work involved and the steps needed to create an effective indoor air quality solution.
