Triangle Radon Defense Q&A

Radon testing is strongly recommended during real estate transactions. Many homebuyers request radon testing as part of the inspection process, and if high levels are found, a mitigation system may be required before closing.

The only way to know your home’s radon level is through testing. Radon levels can vary from home to home — even in the same neighborhood — so professional testing is the most reliable way to determine if radon mitigation is needed.

If high radon levels are found in your home, a qualified professional can install a radon mitigation system and effectively reduce them. Radon mitigation typically involves installing a vent pipe and a fan that pulls radon from beneath the foundation and vents it safely outside, before it can enter the living spaces. This continuous airflow helps maintain lower radon levels inside the home.

Radon enters homes primarily through cracks and openings in the foundation. It can seep from the soil beneath and around a house as the gas naturally moves up. Common entry points include gaps in the foundation floor, walls, sump pits, and around pipes or cables. Radon can also enter through well water in certain areas, although this is less common.

Radon mitigation systems typically use a fan and vent pipe system to draw radon gas from beneath your home and release it safely above the roofline. This prevents radon from entering your living space and keeps levels below EPA-recommended limits.

Costs can vary depending on your home’s size, foundation type, and existing conditions. We provide free, no-obligation estimates so you know exactly what to expect.

Yes, radon is found throughout North Carolina, with some counties showing higher concentrations than others. The North Carolina Department of Health and Human Services recommends testing every home, regardless of location.

Radon exposure doesn’t have immediate symptoms. However, long-term exposure to high radon levels can increase the risk of lung cancer. Symptoms of lung cancer, which can develop years after exposure, include persistent cough, shortness of breath, chest pain, and coughing up blood. If you suspect high radon levels in your home, it's essential to get tested, as the risks are related to prolonged exposure rather than immediate symptoms.

Our business hours are Monday to Friday, from 9:00 AM to 4:00 PM. We are closed on weekends and most holidays.

A radon mitigation system is a ventilation system designed to reduce radon gas levels inside a home. It typically uses a fan and a series of pipes to draw radon from beneath the foundation and safely vent it outside, preventing it from entering your living space.

Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil, rock, and water. It’s odorless, tasteless, and invisible — but prolonged exposure can lead to serious health risks, including lung cancer. The EPA ranks radon as the second leading cause of lung cancer in the U.S.

The Environmental Protection Agency (EPA) recommends that homes be fixed if the radon level is 4 picocuries per liter (pCi/L) or higher. However, radon levels below 4 pCi/L can still pose a risk, and in many cases, may be reduced with proper mitigation techniques.
