Often times, especially in new construction, a radon reduction system may already be present in a home. Unless a valid measurement report is provided, it is impossible to know if an existing system is effectively reducing indoor radon below the EPA’s recommended level of 4 picocuries per liter. Even if the system is reducing the levels, it may not meet the standards set forth by organizations such as the NRPP and EPA.

We can assess an existing radon reduction system and ensure it is not only functional, but proper. An improperly installed system can cause back-drafting of passively exhausted appliances, lack a visual monitoring system, discharge in a manner that may allow re-entry of radon into living spaces or have other defects. We can certify and test a system, and provide recommendations and cost estimates for any improvements.
