Radon Testing
What Should You Expect?
Short Term Testing
Both short term and long term testing are highly recommended. Here is what to expect when you book an assessment.
Our radon testing process starts with a quick walkthrough of your home so we can choose the best testing locations. A certified technician will look at your foundation type (basement, crawl space, slab), note any potential entry points like cracks or sump pits, and ask a few questions about your heating, cooling, and ventilation systems. Based on this, we’ll place one or more radon test devices in key living areas—typically the lowest level of the home where people spend at least four hours a day. These devices are set on a stable surface, away from drafts, exterior walls, and heat sources to make sure the readings are accurate.
Next Steps
Once the monitors are in place, we’ll explain the “closed-house conditions” needed for a proper test. That usually means keeping windows closed and exterior doors opened only briefly, and using your heating or cooling system as normal. For short-term tests, the devices will remain in your home for a minimum of 48 hours, sometimes a bit longer, depending on the type of monitor and your specific situation. Throughout this period, the devices continuously measure radon levels in the air, recording data that lets us see both the average level and how it may have fluctuated over time.
Finally
At the end of the test, we return to collect the devices and download or analyze the results. You’ll receive a clear, easy-to-understand report that explains your home’s radon levels, how they compare to recommended guidelines, and whether any action is needed. If levels are elevated, we’ll walk you through your options for mitigation, answer any questions you have, and, if you wish, connect you with trusted radon reduction professionals. Our goal is not only to test, but to give you peace of mind and a clear plan to keep your home’s air safe.
Long Term Testing
For homeowners who want the most complete picture of their radon levels, Royal Radon also offers long-term testing. Instead of running for just 2–7 days like a short-term test, long-term monitors typically stay in place for 90 days or more, sometimes up to a full year. This allows the device to track how radon levels rise and fall with changes in weather, ventilation, and daily living patterns. Long-term testing is often done over the fall and winter months, when homes are more tightly closed and radon levels tend to be at their highest, but we’ll discuss timing with you and choose a period that makes sense for your family.
The setup is simple and designed to blend into your normal routines. A compact, professional-grade monitor is placed on a tripod or shelf in a key living area, where it quietly records radon levels around the clock. You don’t need to change your heating or cooling usage, and you can continue opening doors as usual—just avoid moving or tampering with the device and try not to set up fans or air purifiers aimed directly at it. Over time, the monitor accumulates a detailed record of your home’s radon patterns, which Royal Radon then downloads and analyzes at the end of the test period. You’ll receive a clear report showing your long-term average, any peaks that occurred, and practical recommendations based on those results, so you can decide on next steps with confidence and minimal disruption to your everyday life.
