Regardless of your results, we recommend follow-up testing.

Because radon is a naturally occurring gas that comes from the ground, levels can fluctuate with varying weather and seasonal conditions. If you test in the warm summer months, we recommend testing again in the winter. Radon levels often increase in the colder months due to pressure changes.
