Radon Testing in Kensington, Maryland

Radon testing in Kensington's historic district and surrounding neighborhoods

Kensington's historic core, listed on the National Register of Historic Places, is full of Victorian-era homes with wraparound porches and older, less standardized foundations — exactly the kind of housing where a professional radon test, rather than a guess based on the house next door, matters most. Beyond the historic district, neighborhoods like Rock Creek Hills, Kensington Heights, and Chevy Chase View carry mid-century colonials and split-levels on mature, tree-covered lots, many built in the postwar decades when foundation practices varied from block to block.

Here's a detail worth knowing if you're selling in Kensington: unlike most of Montgomery County, the incorporated Town of Kensington is specifically exempted from the county's mandatory pre-sale radon testing law, according to Montgomery County's Department of Environmental Protection. That doesn't mean radon levels are any different inside town limits — geology doesn't stop at a municipal boundary — it just means a Kensington seller isn't legally required to test the way a seller in neighboring Wheaton or Rockville is. Buyers and sellers often test anyway, for the same reason anyone tests: to actually know the number.
