Every radon decision starts with one number: yours. Warren County’s average indoor reading is 14.0 pCi/L — among the highest county averages in Kentucky, more than three times the EPA action level of 4.0 pCi/L — but averages don’t tell you what’s in your house. Over karst, two identical homes on the same street routinely test wildly differently. The only way to know is to measure.
We provide certified professional radon testing for homes and businesses in Bowling Green and across south-central Kentucky: 48-hour results, tamper-resistant equipment, and a written report you can hand to a buyer, a lender, or a radon mitigation system installer.
We place a continuous radon monitor in the lowest livable level of your home — a device that samples the air every hour for 48 hours and records the pattern, not just the average. Continuous monitors are tamper-resistant: they log movement, power interruptions, and abnormal swings, which is why their results stand up in real estate transactions where a mailed-in charcoal kit wouldn’t.
Before the test, the house goes into closed-building conditions — windows shut, doors used normally — so the reading reflects the air your family actually breathes over a winter of closed windows. After 48 hours we collect the monitor and deliver a certified written report, usually the same day.
On a closing timeline, testing is rarely optional and never leisurely. Buyers’ inspectors flag radon constantly in Warren County, Kentucky law requires sellers to disclose known radon results, and when a lender, relocation company, or contract requires a radon test, it must be a professional one. We work inside inspection windows every week: test placed within days of your call, results 48 hours later, report delivered to whoever your contract requires.
A high reading doesn’t have to kill a deal. A mitigation system typically resolves it within days — often negotiated as a seller credit — and an installed, verified system turns a disclosure liability into a selling point.
The Kentucky Radon Program offers free mail-in test kits to residents, and we’ll say plainly: a free kit is a fine first step if you’re simply curious. What a kit can’t do is satisfy a real estate contract, a lender, or a relocation company — and charcoal kits are sensitive to placement mistakes, humidity, and the two weeks they spend in the mail. If the number is going to matter to a transaction, or you want certainty instead of a ballpark, it needs to be a professional test.
Buying or selling a home. The inspection window is the moment. Testing after closing means negotiating with nobody.
You’ve never tested. Most Bowling Green homes haven’t. Given the county average, “never tested” here is a number worth knowing.
Your neighbor tested high — or low. Karst makes radon hyper-local. Their number isn’t your number, in either direction.
After any foundation, HVAC, or major renovation work. Changes to airflow and pressure change how radon enters.
Every two years, and after mitigation. Systems get verified when installed, then retested on a schedule — fans age, houses settle, geology shifts.
Radon is measured in picocuries per liter (pCi/L). The EPA action level is 4.0 pCi/L — at or above it, fix the house. Between 2.0 and 4.0, the EPA still recommends considering mitigation; there’s no known safe level of radon exposure. For context, the EPA estimates radon causes about 21,000 lung cancer deaths in the US every year — second only to smoking. When your report comes back, we walk you through exactly what your number means and what — if anything — to do next. If the answer is a mitigation system, the retest that verifies it is built into the job.
How long does testing take?
48 hours of monitoring, with the report usually delivered the same day the monitor comes down. Real estate timelines are our normal operating mode.
Do I have to be home?
Only for placement and pickup — about fifteen minutes each. The monitor does the rest.
Can I just open the windows before the test?
Closed-building conditions are part of a valid test, and continuous monitors log the telltale swings that ventilation causes. If a test looks manipulated, inspectors and lenders will reject it — so the honest answer is: it doesn’t work, and it delays your closing.
What if my result is high?
Then you know — which puts you ahead of most of the county. A properly designed mitigation system brings even severe readings below 4.0 pCi/L, usually within days of installation.
Is winter or summer better for testing?
Radon runs higher in winter when houses are sealed, but a valid test can be run any time of year under closed-building conditions. If you’re testing for a transaction, the calendar is your contract, not the seasons.
You can’t smell it, see it, or taste it — but in 48 hours you can know. Testing in Bowling Green starts with a phone call.
