Radon is a naturally occurring radioactive gas that can enter any home. The EPA recommends testing because radon levels can vary greatly from one home to the next. A neighboring home's test result cannot tell you the radon level in your home.
Radon levels can vary significantly from home to home. Local radon data can show where elevated readings have been reported, but it cannot determine the radon level in your home. Only a radon test can do that.
Schedule a Radon Test

DIY radon test kits can be useful, but accurate results depend on proper placement, closed-house conditions, and following the test instructions carefully. Weather, delays, or interference with the test can also affect the results.
Professional testing provides much more information. I use a Continuous Radon Monitor (CRM) that records measurements throughout the 48-hour test and also monitors temperature, humidity, and conditions that may indicate tampering. The data is then reviewed to provide a clear, professional radon measurement you can rely on.
Elevated radon doesn't mean there's something wrong with the home or that you shouldn't buy it. Radon levels can usually be reduced with a properly designed mitigation system. The type and cost of mitigation depend on the home, foundation, radon level, and availability of qualified contractors. If elevated levels are found, I can help you understand your test results and the appropriate next steps.
