Radon is a naturally occurring radioactive gas that seeps into homes through cracks in the foundation, gaps around pipes, and other openings in contact with the ground. It is colorless, odorless, and tasteless, making it impossible to detect without specialized equipment. According to the EPA, radon is the second leading cause of lung cancer in the United States, responsible for an estimated 21,000 deaths each year.
East Tennessee's geology is a major factor in our elevated radon risk. The region sits atop the Chattanooga Shale formation, a uranium-rich rock layer that produces significant amounts of radon gas. The EPA classifies our entire region as Zone 1, meaning the predicted average indoor radon level exceeds 4.0 pCi/L -- the threshold at which the EPA recommends mitigation. In practice, approximately 30% of homes tested in East Tennessee exceed that level.
Whether you are buying a home, selling a home, or simply want peace of mind in the home you already own, professional radon testing is a straightforward and affordable way to protect your family's health. If levels are elevated, mitigation systems are effective and typically cost between $800 and $1,500 to install.
How Professional Radon Testing Works
Equipment Placement
Steven places a professional continuous radon monitor (CRM) in the lowest livable level of your home. The device records radon levels every hour.
48-Hour Monitoring
The monitor runs for a minimum of 48 hours under closed-house conditions, capturing accurate hourly readings throughout the testing period.
Results & Report
Steven retrieves the monitor, generates a detailed report showing average levels and hourly trends, and explains the results and any recommended next steps.
30 Years of Construction Knowledge Behind Every Test
Steven Northup's 30 year construction background gives him a unique advantage when it comes to radon testing. He understands how homes are built, where foundation vulnerabilities exist, and how building materials and techniques affect radon entry points. As an InterNACHI Trained inspector, he follows strict testing protocols to ensure accurate, reliable results every time.
If your test reveals elevated radon levels, Steven can explain exactly what mitigation involves, where a system would likely be installed in your specific home, and what you should expect to pay -- all based on real construction knowledge, not guesswork.
