Radon testing in Brooklyn: what to know
Brooklyn's carpet stock ranges from decades-old wool stair runners in the brownstone belt — Park Slope, Brooklyn Heights, Bed-Stuy, Carroll Gardens — to wall-to-wall carpet in dense pre-war rental buildings in Flatbush and Crown Heights, to oversized area rugs on polished concrete in the converted-industrial lofts of Williamsburg and Greenpoint. Fibre type, age and moisture sensitivity all vary block to block, so a one-method approach doesn't hold across the borough.
Walk-up-only access is the defining logistics challenge across most of brownstone Brooklyn — carpet-cleaning equipment has to go up narrow interior stairs on nearly every row-house job, while the waterfront's loft conversions and newer towers add freight-elevator scheduling instead.
High-turnover rental stock in Flatbush, Crown Heights, Bushwick and Williamsburg keeps move-out cleaning in constant demand, and hardwood floors sitting directly under old area rugs in the borough's original housing carry real moisture risk if drying time isn't respected between jobs.
Signs you need radon testing
- You're buying or selling a home and radon testing is part of the transaction or requested by the buyer
- You've never tested your current home for radon, or it's been several years since the last test
- You have a finished basement or spend significant time in the lowest level of the home
- A neighbouring property or your general area has previously tested with elevated radon
- You want a long-term test to understand your home's actual average radon exposure across seasons
How we treat radon testing in Brooklyn
Radon is a naturally occurring gas produced by the breakdown of uranium in soil and rock, and it can seep into homes through foundation cracks, sump pits, and gaps around pipes entering the basement or lowest level. It has no smell, no color and no taste, which means the only way to know whether a home has an elevated radon level is to test for it — you cannot detect it by any of your senses, and levels vary from house to house even on the same street depending on soil conditions and how the specific foundation was built.
There are two general testing approaches. Short-term tests (commonly run over a period of a few days) give a quicker read and are common in real-estate transactions where time is limited; long-term tests (commonly run over 90 days or more) give a more representative picture of a home's average radon level across seasonal variation, since radon levels can fluctuate. The EPA publishes guidance on both testing approaches and on what level of radon warrants mitigation — we follow that guidance rather than asserting our own threshold.
