Single Radon Test Kit

Buy one of our DIY radon test kits and know your home's radon levels in no time. Just one test will bring you closer to a healthier home and peace of mind.

A single DIY radon test kit is a short term test that, depending on the test, remains in your home for just a few days. In doing so, it measures the varrying radon levels-- as the radon levels shift throughout the day due to weather, soil conditions, wind, encapsulation, and more. However, this test will provide an accurate average of the radon readings. Though quick, this short term test will not be able to show you a year round average. If you're completely unaware of the building's previous radon levels, a short term test is a fast and accurate way to have the reading.

Even if the building has already been tested, this is the perfect way to compare results and have up to date readings! Looking for year round results? Check out the long term radon test kits.
