Radon FAQs
What is radon?
Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil and rock. It can enter homes through foundation cracks, sump pits, crawl spaces, and other openings, building up to unsafe levels indoors.
How do I know if my home has radon?
You cannot see, smell, or taste radon. Testing is the only way to determine radon levels in your home. Professional radon testing provides accurate results and proper placement for reliable readings.
Is radon really dangerous?
Yes. Long-term exposure to elevated radon levels increases the risk of lung cancer. Radon is the second leading cause of lung cancer overall and the leading cause among non-smokers.
What radon level is considered unsafe?
The EPA recommends mitigation for homes with radon levels at or above 4.0 pCi/L. Levels between 2.0 and 3.9 pCi/L should also be addressed, especially with long-term exposure.
Can new homes have radon?
Yes. New construction homes can have high radon levels just like older homes. Energy-efficient construction can sometimes trap radon inside, allowing levels to rise.
How long does radon testing take?
Short-term radon tests typically take 48 to 96 hours. Long-term tests can measure radon levels over several months for a more complete average.
How does a radon mitigation system work?
Most systems use sub-slab depressurization. A fan pulls radon gas from beneath the foundation and vents it safely outside, preventing it from entering the home.
How effective is radon mitigation?
Professionally installed systems can reduce radon levels by up to 99 percent. Effectiveness depends on proper design, installation, and ongoing system maintenance.
Will a radon system increase my energy costs?
Radon mitigation systems use low-energy fans and typically add only a small amount to monthly utility costs while providing continuous protection.
Does a radon system need maintenance?
Yes. Fans, seals, and venting components should be checked periodically. Regular maintenance ensures the system continues to perform properly and keeps radon levels low.
Should I test again after mitigation?
Yes. Post-mitigation testing confirms the system is working effectively. Ongoing testing every few years is also recommended.
Is radon a problem only in basements?
No. While basements often have higher levels, radon can affect any level of a home. Testing should be done in the lowest livable area.
When should I test for radon?
Testing is recommended before buying or selling a home, after renovations, and every few years even if previous results were low.
Can I install a radon system myself?
DIY systems are not recommended. Professional installation ensures proper design, code compliance, and effective radon reduction.
