Radon Testing & Mitigation

Protect your family from the leading cause of lung cancer among non-smokers with proper radon testing and mitigation.

Why Radon Testing is Critical

Radon is a radioactive gas that occurs naturally from uranium decay in soil. It's invisible, odorless, and the second leading cause of lung cancer, responsible for about 21,000 deaths annually in the US according to the EPA. The only way to know if your home has dangerous radon levels is to test.

The EPA recommends taking action if radon levels are 4 pCi/L or higher. Testing is inexpensive and easy, and mitigation systems are effective at reducing radon to safe levels.

If Your Test Shows High Radon Levels

If your radon levels are 4 pCi/L or higher, you need a radon mitigation system. This typically involves a certified radon mitigation contractor installing an active soil depressurization system with a fan and vent pipe to draw radon from beneath your home and vent it safely outside. Professional installation is required and typically costs between $800-$2,500 depending on your home's foundation type and size.

Understanding Radon Testing

Short-Term Tests: 2-7 days, good for initial screening. Results can vary based on weather and season.

Long-Term Tests: 90+ days, more accurate representation of average radon levels. Recommended for confirming results.

Digital Detectors: Provide continuous monitoring and instant readings. Best for ongoing awareness and post-mitigation verification.

When to Test: Test when buying a home, after major renovations, and periodically (every 2-5 years) as radon levels can change.

Test Location: Test the lowest lived-in level of your home. If you have a basement you use, test there first.
