"adon After I contacted him, he responded promptly.  While evaluating the area that needed radon mitigation, he called to discuss an area that had not been evaluated by inspectors (not affiliated with him).  After accepting his price, we agreed on the day for the installation.  During the installation, he was respectful and communicative.  After completing the installation, he provided written warranties for me and the buyer.  I highly recommend Keystone Radon Mitigators.

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.
