What is radon
Radon is a naturally occurring radioactive gas that can seep into homes from the soil, usually through the foundation, cracks, and gaps around pipes. Levels vary from house to house, even between neighbors, so a test on one home does not tell you about the one next door.
How testing works
A radon test measures the concentration of the gas in the lowest livable level of the home. Short-term tests generally run at least 48 hours, and the home should be kept under closed-house conditions while the test is in progress. When the test is done, you receive the results with an explanation of what they mean.
What the numbers mean
The U.S. EPA recommends taking action to reduce radon in homes that test at 4 pCi/L or higher, and suggests considering action for results between 2 and 4 pCi/L. If your result is high, there are proven ways to reduce radon levels, and the finding can be a negotiating point during a purchase.
Add it to your home inspection
Radon testing is commonly done alongside a home inspection during the buying process. Call or text to schedule both so they fit inside your contract timeline.
