Radon Awareness: Why Testing Matters in 2026
When buying a home, most of our attention goes toward the things we can clearly see: the age of the roof, the condition of the floors, and the layout of the kitchen. But what about the things you can't see?
In 2026, indoor air quality is taking center stage in the real estate world, and at the forefront of that conversation is Radon.
Radon is a naturally occurring radioactive gas. It is completely invisible, it has no smell, and it leaves no taste in the air. Yet, according to the EPA, it is the number one cause of lung cancer among non-smokers.
Here is exactly what you need to know about Radon, the hidden health risks it poses, and why testing your home is a non-negotiable step for protecting your family.
What is Radon and How Does It Enter Your Home?
Radon comes from the natural breakdown of uranium in soil, rock, and water. As this radioactive decay occurs, the resulting gas rises up through the earth and into the atmosphere.
Outdoors, Radon disperses safely into the air. But when this gas gets trapped underneath a home's foundation, it searches for a way to escape. It finds its way inside through tiny cracks in the concrete slab, gaps around service pipes, construction joints, and even microscopic pores in the concrete itself. Once inside, it becomes trapped, building up to dangerous concentration levels.
And yes, this happens right here in Florida. While some regions are known to have higher concentrations, elevated Radon levels have been found in homes in all 50 states, regardless of whether the home is new, old, built on a slab, or over a crawlspace.
The Health Risks You Can’t See
Because Radon has no physical presence that human senses can detect, it is a silent threat. You will not experience coughing, headaches, or allergy-like symptoms when exposed to Radon.
Instead, the danger is long-term. As you breathe in Radon gas, radioactive particles get trapped in your lungs. Over time, these particles release small bursts of energy that damage lung tissue and DNA, eventually leading to lung cancer.
The Surgeon General and the EPA estimate that Radon causes over 21,000 lung cancer deaths every single year in the United States alone. If you are a smoker, your risk of developing lung cancer from Radon exposure is exponentially higher.
Why 2026 is the Time to Test (The Energy-Efficiency Catch)
Over the last decade, building codes and construction practices have drastically improved. Today’s homes are incredibly energy-efficient. We use better spray foam insulation, tighter impact windows, and advanced weather stripping to keep our air conditioning from escaping.
While this is fantastic for your electric bill, there is a catch: tighter homes trap gases.
Older, draftier homes allowed indoor air to naturally cycle out through gaps in the windows and attic. In 2026, homes are practically hermetically sealed. If Radon is seeping up through your foundation, it has absolutely nowhere to go. This makes Indoor Air Quality Testing and dedicated Radon testing more important now than ever before in history
Preventative Steps: Testing and Mitigation
The only way to know if your family is at risk is to test. The EPA strongly recommends that every home be tested for Radon, especially during a real estate transaction.
Professional Testing: During your due diligence period, a certified professional will set up a calibrated continuous Radon monitor in the lowest livable level of the home. The machine will run for a minimum of 48 hours to measure the exact picocuries per liter (pCi/L) in the air.
Understand the Action Level: The EPA has set an "action level" of 4.0 pCi/L. If your home tests at or above this number, mitigation is strongly recommended.
Radon Mitigation Systems: If a home has high Radon, don't panic. You don't have to walk away from your dream house. Radon mitigation is highly effective. A licensed contractor can install a specialized ventilation pipe and fan system that pulls the gas from beneath the foundation and vents it safely above the roofline.
Peace of Mind is Only a Test Away
Protecting your family's health is the ultimate priority. Whether you are buying a historic bungalow or a brand-new, ultra-efficient modern build, Radon testing is a small investment that yields massive peace of mind.
At KENCO Inspections, we utilize advanced continuous Radon monitors to provide you with fast, highly accurate, lab-certified results. Don't leave your indoor air quality to chance.
