Leawood sits in Johnson County, and the whole county is EPA Radon Zone 1. I test and mitigate homes across Leawood all the time, from the established streets in north Leawood near Mission Road down to the newer Hallbrook and Iron Horse builds off 143rd. If your test came back high, there is a clean, permanent fix.
📞 Call (816) 451-5827 Get My Free QuoteLeawood is one of the most tested corners of the metro, partly because so many homes change hands here and partly because homeowners in this area tend to be careful. The north end around Lee Boulevard and Mission Road holds Leawood's older ranch and two-story homes, while south Leawood keeps expanding with large newer builds through Hallbrook, Iron Horse, and the developments off 143rd Street. Neither end is safer from radon than the other, because the gas comes up out of the ground rather than out of the age of the house. I have logged readings above the 4.0 pCi/L action level in the 66206, 66209, 66211, and 66224 ZIPs alike, and the big finished basements Leawood is known for give the gas plenty of room to collect.
Testing is the starting point, and it is simple. I place a continuous radon monitor on the lowest livable level of your Leawood home, usually the basement, and let it run under closed-house conditions for the measurement period. You get an hour-by-hour reading rather than a single blurry average, which matters when a number lands close to the line. If it comes back under 4.0 pCi/L, you are done. If it is over, I walk you straight into the fix. My radon testing page covers the details.
When a Leawood home tests high, I install an active sub-slab depressurization system. That means coring through the basement floor, sealing a PVC pipe into the slab, and running it up through an inline fan that pulls the soil gas out from under the foundation and vents it above the roofline. On the larger footprints common in south Leawood I plan the routing so the pipe stays tidy and out of sight, and I retest afterward to confirm the number dropped below the EPA limit. My mitigation systems page has more.
With how quickly Leawood homes move, a high radon reading during inspection is a regular call for me. I move transaction jobs to the front of the line and can usually install and deliver a post-mitigation test inside the inspection window so your closing does not slip. My real estate radon page covers the process.
