Radon is present indoors and outdoors. However, outdoors it is found at very low levels and can even be found in river and lake water. It is typically found at higher levels indoors because of the closed in air flow.
RCS is trained to install these systems. We are trained in how to seal off every radon entry point in a concrete slab and crawl space. We are also trained on how to ensure that radon gas is pulled through the system and safely vented outside of the structure, ensuring that the harmful radon gas never even enters your home.
