Radon testing in Asheville

Radon is an invisible, odorless radioactive gas that naturally seeps from the soil and can accumulate in homes to dangerous levels, increasing the risk of lung cancer. Our professional radon testing can help detect and measure radon concentrations in your home, giving you peace of mind or the knowledge to take action with effective radon mitigation systems.

What Is Radon and Why Does It Matter?

Radon gas is a naturally occurring radioactive element found in the earth’s crust. It’s formed by the decay of uranium in soil, rock, and water and escapes into the air — including your home’s indoor air.

When radon enters a building, it can build up to elevated radon levels that pose serious health risks. In fact, radon is the second leading cause of lung cancer after smoking and is considered a significant public health risk by the EPA and other national radon programs.

Why Is Radon Testing Necessary in Asheville?

Asheville and the surrounding Western North Carolina area have been identified as regions with moderate to high radon potential. The geology and soil types in this region can allow airborne radon to easily enter homes, especially those with certain structural features.

Testing is the only way to know the radon level in your home since it’s completely invisible and has no immediate symptoms.

What Homes Are Most at Risk for Radon?

Certain homes in Asheville are more vulnerable to radon exposure, including:

asheville radon entry points
  • Homes with crawl spaces or earth floors: Radon can easily enter through cracks or openings in these areas.
  • Basements and lower-level rooms: Radon gas tends to accumulate in the lowest parts of a building like crawl spaces.
  • Homes with poor ventilation or high humidity: These conditions can trap radon gas indoors.
  • Older homes with foundation cracks or vent pipe gaps: Sealing cracks can help reduce radon concentrations.
  • Homes built on soil rich in uranium: Local geology influences radon levels significantly.

If your home determines higher radon concentrations, professional radon mitigation may be necessary to reduce radon levels effectively.

How Does Radon Testing Work?

Radon testing can be done through short term tests (lasting 2 to 7 days) or long term tests (lasting 90 days to one year). Short term radon test kits provide quick insight into radon levels but may be affected by variables like barometric pressure and weather. Long term kits give a more accurate average radon level by measuring radon concentrations over several months.

Our qualified testers use national radon proficiency program certified radon test devices to ensure accuracy. These devices detect radon concentrations measured in picocuries per liter (pci/l) of air, the standard unit to express radon level.

We offer discounted radon test kits to Asheville residents so you can test your home affordably. These radon test kits are easy to use—simply place the test kit in the lowest lived-in area of your home and follow instructions carefully. After the testing period, you send the kit back to the lab for analysis.

For best results, a second short term test is often recommended if initial results show elevated radon levels (above EPA recommended action level of 4 pci/l). Testing for radon should be done at least every two years or when buying or selling a home as part of real estate transactions.

Radon levels are measured in pci/l:

  • 4 pci/l or higher: EPA recommends taking action to reduce radon.
  • 2-4 pci/l: Consider radon reduction steps to minimize risk.
  • Below 2 pci/l: Low risk, but regular testing is still advised.

Indoor radon levels can fluctuate due to barometric pressure, weather, and ventilation. If your test results show high radon levels, our radon professionals can recommend and install proven radon mitigation systems to reduce radon concentrations and improve indoor air quality.

How to Reduce Radon Levels in Your Home

At A-1 Pest Control, we specialize in EPA-approved mitigation strategies designed to deliver long-lasting protection for your home and family.

Sub-Slab Depressurization (Active Soil Depressurization)

This is the most effective and commonly recommended radon mitigation method. A radon mitigation system is installed beneath the foundation, where a radon fan draws the gas from the soil through a pipe and safely vents it above the roofline—away from windows and air intake points.

Sealing Cracks and Openings

Cracks in foundation walls and floors, gaps around service pipes, and open sump pits can all serve as entry points for radon gas along with pests. We use professional-grade sealants and vapor barriers—such as high-density polyethylene sheets in crawl spaces—to block these entryways and enhance the effectiveness of other mitigation systems.

Improved Ventilation

Enhancing ventilation in crawl spaces, basements, and other enclosed areas can help dilute radon concentrations and prevent it from accumulating indoors. This may involve installing vents or fans to increase air exchange with the outdoors, particularly in homes with passive airflow issues.

Installing Ventilation Pipes

In some homes, installing a vertical pipe system (often in conjunction with a fan) can redirect radon from the soil to the outside air before it enters the house. These vent stacks are typically routed through an interior wall or exterior siding and release radon above the roofline to ensure it's safely dispersed.

Symptoms of Radon in Your Home — Can You Tell?

Radon exposure has no immediate symptoms or warning signs. It does not cause any smell, taste, or visible effects in your home’s air. Because radon is odorless and invisible, testing is essential. Prolonged exposure to high levels of radon increases your risk of lung cancer, which is why early detection through radon testing is vital.

Although you can’t physically sense radon in your home, long-term exposure may eventually result in symptoms related to lung damage, including:

warning signs of radon in asheville
  • Persistent cough that doesn’t go away
  • Shortness of breath, especially during physical activity
  • Chest pain or tightness
  • Wheezing or hoarseness
  • Coughing up blood (in severe cases)
  • Recurring respiratory infections like bronchitis or pneumonia
  • Unexplained weight loss and fatigue

These symptoms are most often associated with radon-induced lung cancer, which typically develops over years of exposure. If you or someone in your household is experiencing these symptoms—especially if there’s no history of smoking—radon may be a contributing factor.

Radon and Lung Cancer Risk

The EPA estimates that radon causes thousands of lung cancer deaths annually, making it a serious public health concern. Smokers and non-smokers alike are at risk if exposed to elevated radon levels over time. Children and those with compromised lungs are especially vulnerable.

By testing your home for radon and installing mitigation systems if needed, you can drastically reduce your family’s risk.

FAQs About Radon Testing in Asheville, NC

Yes. Radon exposure is a leading cause of lung cancer, and the only way to know if your home has elevated radon levels is through testing. North Carolina’s geology makes radon testing especially important.

Radon enters through cracks, openings, and foundation gaps from soil underneath your home. Poor ventilation and certain soil types increase radon concentrations indoors. It’s also a breeding spot for destructive pests like rodents and termites.

The EPA recommends testing every two years, or when you move into a new home, after home improvements, or if you install a new heating system.

Yes, with radon test kits. However, using a qualified tester or a certified radon professional ensures more reliable results.
