A home can look flawless on showing day. Fresh paint. Clean mechanicals. Solid roofline. But there are risks you cannot see, smell, or feel. Radon is one of them.
At Focused Property Inspections, radon testing is not an upsell. It is risk management.
The Situation
Radon is a naturally occurring radioactive gas formed by the breakdown of uranium in soil and rock. It moves through the ground and can enter homes through cracks in foundations, slab penetrations, sump pits, and crawlspaces.
The U.S. Environmental Protection Agency (EPA) states plainly:
“Radon is a radioactive gas that you can’t see, smell, or taste.”

Because it is invisible and odorless, homeowners often assume that if the home is new, well built, or located in a “low risk” area, it must be safe. That assumption is wrong.
The Problem
Radon is the second leading cause of lung cancer in the United States.
The EPA reports:
“Radon is the second leading cause of lung cancer. It’s responsible for about 21,000 lung cancer deaths every year.”

The Centers for Disease Control and Prevention reinforces this:
“Breathing radon over time increases your risk of lung cancer.”

This is not speculative. It is documented public health data.
What makes radon particularly relevant in real estate transactions is variability. Two houses next door to each other can test dramatically differently. One may be below action level. The other may exceed it.
According to the EPA:
“Homes next door to each other can have different radon levels.”

That means you cannot rely on regional averages or neighbor results. Every home must be tested individually.
New Homes Are Not Automatically Safe
There is a common myth that new construction eliminates radon risk. It does not.
The EPA clarifies:
“Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.”

Modern homes are often tighter and more energy efficient. That is good for heating and cooling. It can also allow radon to accumulate if not properly vented.
When Should You Test?
The EPA recommends action when radon levels reach or exceed 4.0 picocuries per liter (pCi/L):
“EPA recommends homes be fixed if the radon level is 4 pCi/L or more.”

In a real estate transaction, testing is typically conducted over a short-term period under controlled conditions. The result gives buyers and sellers objective data before closing.
This is not about fear. It is about informed decision-making.
The Solution
Radon mitigation is both common and effective.
The EPA explains:
“Radon reduction systems work. Some radon reduction systems can reduce radon levels in your home by up to 99%.”

https://www.epa.gov/sites/default/files/2016-02/documents/2016_consumers_guide_to_radon_reduction.pdf
Mitigation systems typically involve active soil depressurization. A vent pipe and fan system draw radon from beneath the slab or crawlspace and safely discharge it above the roofline.
It is not exotic technology. It is proven building science.
Why This Matters in a Transaction
A home inspection evaluates structure and systems. Radon testing evaluates health risk.
Together, they provide a clearer picture of the property.
For buyers, testing protects your family.
For sellers, testing protects your transaction.
For agents, testing protects your client relationships and professional credibility.
The National Association of Realtors notes:
“Radon testing is an important part of many real estate transactions.”

This is standard practice in many markets for a reason.
Clarity Over Assumption
Radon is not visible damage. It does not show up as a cracked joist or missing flashing. It is a data point. And in real estate, data matters.
At Focused Property Inspections, our approach is disciplined and objective:
• Controlled test placement
• Documented chain of custody
• Clear reporting
• Coordinated communication with all parties
One call. One appointment. One report.
Radon testing is a small investment compared to the cost of a home. It is even smaller compared to the cost of untreated risk.
If you are buying, selling, or representing a client, do not rely on assumptions. Rely on measurement.
Schedule early.
Test properly.
Decide with clarity.
