The property had a radon reading of 4.3 pCi/L with no mitigation system in place and new tenants scheduled to move into the home.
A radon mitigation system is planned to reduce radon levels before occupancy, with careful routing designed to maintain a clean finished appearance throughout the home.
The home tested at 10.3 pCi/L with no active multi-point mitigation system in place beneath the foundation.
A two-point radon mitigation system is planned to improve sub-slab airflow, strengthen radon reduction performance, and allow flexibility for future basement improvements.
The home had an existing radon mitigation system with an older fan that needed replacement. Replacing a fan helps maintain the system’s ability to draw soil gases from beneath the foundation and vent them safely outdoors.
We replaced the old fan with a new RP145 and left a radon test kit for the homeowner. Follow-up testing will help determine the current indoor radon level and confirm the system’s effectiveness.
The initial radon test measured 26.0 pCi/L, well above the EPA’s recommended action level of 4.0 pCi/L. With this elevated reading, a two-point system was selected to provide coverage in separate areas beneath the home.
We plan to install two extraction points, one along the left side of the basement and the other next to the refrigerator. Both points will connect to a system powered by a Festa Hawk fan. Gravel will be used at the extraction locations to help promote airflow beneath the foundation. Once installation is complete, follow-up radon testing will be important to confirm how effectively the system has reduced the indoor radon level.
The home tested at 4.2 pCi/L and included an unencapsulated crawl space, finished basement areas requiring sealing, and an existing WaterGuard drainage system.
A one-point radon mitigation system will be installed, finished basement areas will be professionally sealed, and approximately 900 square feet of crawl space will be encapsulated with CleanSpace to provide effective radon reduction and improved moisture control.
