The county's historic planned neighborhood — rows of similar homes built in the same era, on the same ground. And still: your radon number is yours alone. 48-hour certified tests, one-day mitigation.
Lawrence Park is one of the county's most distinctive places to live — a planned community laid out in the 1910s for General Electric's workforce, where whole streets share the same vintage, the same builders, and often nearly the same floor plan. It's natural to assume that houses this alike would share a radon number too. They don't. Radon depends on the exact soil pocket under each foundation, the specific cracks and joints a century of settling has opened, and how each individual house breathes — so two matching homes three doors apart can test on opposite sides of the EPA action level. In a neighborhood built on sameness, radon is the thing that isn't.
That's the whole argument for testing here: a neighbor's result — high or low — tells you nothing, and the only number that describes your house is a 48-hour test in it, $150–$250 with a certified same-day report. If yours comes back high, mitigation is a one-day install with the sealing these century foundations need built in, verified with a follow-up test. Pricing details are on the cost page; common questions are answered in the FAQ.
