Radon Testing for Your Peace of Mind

Radon is the second leading cause of lung cancer in the U.S.* — and it's completely undetectable without a test.

What Is Radon?

An invisible risk hiding in plain sight.

Radon is a naturally occurring radioactive gas that seeps up from the soil into homes through foundation cracks, sump pits, and crawlspaces. You can't see it, smell it, or taste it — but elevated levels are a serious, well-documented health risk, especially with prolonged exposure.

North Carolina has areas with moderate to elevated radon potential, and levels can vary significantly even between neighboring homes. The only way to know your home's actual level is to test it.

How Testing Works

Simple, accurate, and minimally invasive.

1. Placement

A continuous radon monitor is placed in the lowest livable area of the home — typically a basement or ground floor.

2. 48-Hour Test

The monitor records radon levels continuously over a minimum 48-hour period under regulated conditions, per EPA protocol.

3. Clear Results

You receive a straightforward report of average levels along with what they mean and recommended next steps if mitigation is advised.

Who Should Test

Testing isn't just for buyers.

Home buyers, as part of a purchase inspection or as a standalone test.
Home sellers, to address radon proactively before it becomes a negotiation item.
Current homeowners who have never tested, or whose last test is several years old.
Anyone who has renovated their home's foundation, crawlspace, or HVAC system.
Families with children or anyone spending significant time in below-grade living spaces.

Radon testing can be added to any home inspection or scheduled as a standalone service.

If Levels Are Elevated

An elevated reading isn't a crisis — it's a fixable problem.

If your test comes back at or above the EPA's action level of 4.0 pCi/L, radon mitigation systems are a well-established, effective solution that typically reduce levels significantly. I'll walk you through what the results mean and connect you with next steps.
