When you hire Madison Radon Testing, LLC to do your radon test, you will get quick and reliable results. We are not affiliated with any radon mitigation businesses, so you will receive an independent and unbiased assessment.


We will set up a continuous radon monitor in the lowest livable level of your home (typically the basement). The small machine measures the amount of radon in the air once every hour. Our monitors all have built-in anti-tampering features, so you can rest assured your results are accurate.


After as few as 48 hours, we will pick up the radon monitor and analyze your test's data. That same day, we will email you your measured radon level and a report explaining what your results mean. 


Our Sun Nuclear continuous radon monitor (model 1027) is about the size of a box of crackers.
