Radon Detection and Reduction questions, answered by experts

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

Costs depend on property size, test types, and additional services like mold sampling.

Results from radon testing usually take a week to process after the test period ends, with expedited services sometimes available for urgent cases.

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.
