From 150 pCi/L to a Safer Home: Radon Mitigation in Gray, ME

Cheryl R. in Gray, Maine had a radon test result of 150 pCi/L, an extremely elevated level that required immediate attention. With readings this high, a properly designed mitigation system was essential to help protect the home's indoor air quality and create a safer living environment.

The installation was planned through the basement access located near the garage, utilizing a route that provided an efficient path for the mitigation system. The property already had a sump area and additional pipe penetrations that required sealing as part of the overall radon reduction strategy. A 3" Valterra® gate valve was also incorporated into the project to accommodate the system design.

One unique aspect of the installation was the electrical setup. While a permanent outlet had not yet been installed near the system location, Cheryl planned to add dedicated power after the mitigation work was completed. In the meantime, a nearby outlet at the workbench provided temporary power for system operation and testing.

With the mitigation system installed and operating, the home now has a professionally designed solution addressing one of the highest radon levels we encounter. Projects like this demonstrate how even extremely elevated radon readings can be addressed with the right design, equipment, and installation practices.

From 150 pCi/L to a safer future—another Maine home protected.
