Our Guarantee

Centennial Radon Solutions guarantees in virtually all cases that the system we propose and install will lower the radon levels in your home to below the EPA's action limit of 4 pico-curies per liter. If during the first 13 months after the initial installation the levels exceed the EPA's action limit we will return and augment the installation until the levels meet the EPA's requirements - at no extra charge to you.

This means peace of mind for you and satisfied customers for us.

The fine print: we trust that you understand that this guarantee applies only to systems that have been installed by Centennial Radon Solutions and that the system or the building/structure have not been altered. In some unique sitations (less than 1%) it is not possible to apply the guarantee. If this is the case we will inform you at the time of the quote.

As the gas moves up through the soil it can enter buildings through the foundation and accumulate.
Radon is a Group A or Type A carginogen and has been linked to lung cancer.
