Does Every House Have Radon?
Yes, every house contains some level of radon gas – since this radioactive element occurs naturally in outdoor air and soil, it exists virtually everywhere. The true danger arises when it enters your home through the foundation and becomes trapped indoors, concentrating to hazardous levels over time.
It doesn’t matter if your house is brand new, a century old, built on a concrete slab, or over a crawl space. Any structure can trap radon, and only professional radon testing reveals the actual level exposure in your home – and whether or not you need to take action.

Common Questions
About Radon Testing
Everything you need to know about radon testing in Asheville, Hendersonville, and Western North Carolina.
Is a DIY radon test kit as accurate as a professional test?
DIY radon test kits are widely available and can provide a general indication of radon presence in your home, but they are not equivalent to professional radon testing. Most consumer kits rely on charcoal canisters that must be mailed to a lab, introducing variables like improper placement, exposure to humidity, and delayed processing that can compromise accuracy. Without training in where and how to place a monitor correctly, results can be misleading.
Professional radon testing uses calibrated, certified equipment and follows strict EPA and NRPP protocols for placement, duration, and analysis. A certified specialist also understands how construction type, ventilation, and local geology affect results. When your family’s health is at stake, the precision and reliability of professional radon testing is well worth the investment over a one-size-fits-all kit.
How often should I test my home for radon?
The EPA recommends testing your home for radon every two years, even if previous results came back below the action level. Radon levels are not static. They shift over time as soil conditions change, your home settles, renovation work is completed, or new cracks develop in the foundation. A result that was acceptable several years ago may no longer reflect your current indoor air quality.
If you have had a radon mitigation system installed, regular radon testing becomes even more important to confirm the system is still performing effectively. Testing is also recommended any time you finish a basement, make significant structural changes, or purchase a new home. Staying current with radon testing is one of the simplest and most reliable ways to protect your family’s long-term health.
Should I test for radon if my neighbor’s house tested low?
Yes, absolutely. Radon levels are highly localized and can vary dramatically from one property to the next, even on the same street. Differences in soil composition, foundation type, construction materials, crawl space conditions, and how tightly each home is sealed all influence how much radon accumulates indoors. Your neighbor’s results tell you nothing definitive about what is happening beneath your own foundation.
This is something that nearly two decades of radon testing has made abundantly clear. Homes sitting side by side can produce very different readings, and assuming safety based on a neighbor’s test is one of the most common mistakes homeowners make. The only way to know your home’s actual radon level is to have it professionally tested. Don’t let a false sense of reassurance put your family at risk.
Can weather or humidity affect my radon test results?
Weather conditions can have a real impact on radon levels inside your home, which is why professional radon testing follows specific protocols designed to minimize those variables. Cold temperatures, high winds, heavy rain, and low barometric pressure can all temporarily elevate radon readings by drawing more gas up through the soil and into the home. Humidity can also interfere with certain types of testing equipment under extreme conditions.
Certified radon testing requires closed-house conditions for a set period before and during the test. Doors and windows must remain closed, and any weather disruptions during the testing window should be noted. An experienced radon testing specialist knows how to account for these factors and will advise you if conditions require retesting. Accurate results depend on following the right process, not simply placing a monitor and hoping for the best.
Do I need to test the upper floors of my house or just the basement?
Radon testing is most critical in the lowest livable level of your home, as that is where concentrations are typically highest. If your basement is used as a living space, bedroom, playroom, or home office, it should always be the primary focus of radon testing. Radon levels generally decrease on higher floors, since the gas enters from the ground and dilutes as it rises through the home.
That said, if your lowest level is a slab-on-grade main floor with no basement, radon testing should be conducted there instead. Upper floors are not routinely tested unless the primary living area is located there. The goal is to measure radon where your family spends the most time. A certified radon testing specialist can help you determine the right placement based on your specific floor plan and how your home is used daily.
