Radon Testing in Western North Carolina

Identify Sewer Line Problems Before They Become Costly

Radon is a naturally occurring radioactive gas that you cannot see, smell, or taste — yet it is the second leading cause of lung cancer in the United States. In North Carolina, especially in mountain regions like Asheville, Brevard, and Hendersonville, radon levels are often elevated due to local geology.

At Western North Carolina Property Inspections, we provide accurate, certified radon testing for homes across the region. Whether you’re purchasing a new home, evaluating an existing one, or preparing to sell, knowing your radon levels is essential for long-term health and safety.

Our testing services use calibrated equipment and follow EPA-recommended protocols to deliver reliable results you can act on.

What Is Radon and Why Is It a Concern?

Radon is produced from the natural breakdown of uranium in soil, rock, and water. It seeps into homes through cracks in foundations, gaps in floors, sump pumps, and around plumbing or wiring.

Once inside, radon can become trapped and build up to unsafe levels — especially in basements, crawlspaces, and lower-level living areas. Over time, inhaling radon gas can lead to cellular damage in the lungs and significantly increase the risk of cancer.

Radon Testing Is Especially Important If…

Your home has a basement or crawlspace

You want to verify the effectiveness of an existing radon mitigation system

Radon is a localized risk — two houses next door to each other can have vastly different levels. That’s why every home needs individual testing.

Our Radon Testing Process

We follow strict procedures to ensure reliable, unbiased results. Every test includes:

Initial Setup


We place a continuous radon monitor (CRM) in the lowest livable area of the home, such as a basement or first-floor living space. The monitor:

Remains in place for a 48-hour minimum test period

Measures and logs radon concentrations hourly

Is tamper-resistant and calibrated regularly for accuracy

We advise homeowners to maintain closed-house conditions during the testing period (keeping windows and doors closed except for normal entry/exit).

Monitoring and Data Collection


After 48 hours, we retrieve the device and download its readings. The monitor records:

Guidance on mitigation (if needed)

Reports are typically delivered within 24–48 hours after test completion.

What If High Radon Levels Are Detected?

If your radon levels exceed 4.0 pCi/L, the EPA recommends installing a radon mitigation system to reduce concentrations. These systems use fans and venting to safely redirect radon gas away from the home.

We do not install mitigation systems, but we can recommend next steps and help you interpret the results clearly. Our assessments are always unbiased, with no sales agenda.

In many real estate transactions, radon levels above 4.0 pCi/L become a negotiation point between buyers and sellers. A clear, certified report is a valuable tool for resolving these concerns.
