Radon Testing in Smithfield, NC
You Can’t See It. You Can’t Smell It. But It Matters.
Radon is a naturally occurring radioactive gas. It forms in the soil and can enter homes through small cracks and openings in the foundation, quietly accumulating indoors over time. Because it has no smell, color, or taste, most homeowners never know it’s present without testing.
Radon exposure is the second leading cause of lung cancer in the United States, according to the EPA. The only way to know the radon level in your home is through professional radon testing. 
In Smithfield and the surrounding Johnston County area, homes range from historic properties near downtown to newer subdivisions and rural homes with crawlspaces or slab foundations. Radon can move through the soil beneath any type of foundation and enter a home through small openings in the structure. Even homes located on the same street—or built at the same time—can have very different radon levels. Because of this variability, testing is the only reliable way to determine the radon level inside your home.
Our professional radon testing services in Smithfield, NC use calibrated, professional-grade monitors placed according to EPA testing protocols. The monitors remain in the home for the proper testing period to ensure accurate results. After testing is complete, we provide clear documentation of the radon levels along with straightforward guidance if elevated levels are detected.
Every home is different — even houses on the same street.
If you are buying a home, selling a property, finishing a basement, or it has been more than two years since your last test, it may be time to test.
