Radon testing tends to get lumped in with other home inspection add-ons that people assume are optional unless something seems obviously wrong. That assumption causes real problems, because radon gives no visible warning before it becomes a health risk. For homeowners throughout Toms River, Barnegat, Manahawkin, and the rest of Ocean County, sorting fact from fiction on this topic is worth the few minutes it takes.
Myth: Coastal Homes Are Too Sandy for Radon to Be a Concern
Radon forms when uranium in soil and rock breaks down, and many people assume the sandy, low-lying terrain along the Jersey Shore means radon risk is minimal here compared to hillier parts of the state. In reality, radon concentration depends on localized geology and can vary significantly even within the same zip code. The New Jersey Department of Environmental Protection maintains municipal-level radon potential data specifically because statewide or countywide averages do not reliably predict what is happening in any individual home.
Myth: If My Neighbor’s House Tested Fine, Mine Probably Will Too
Radon testing exists precisely because this assumption fails so often. Two homes built the same year on the same street can show meaningfully different readings depending on foundation type, soil composition directly beneath the structure, and how well sealed the crawl space or basement happens to be. A clean result next door tells you nothing reliable about your own home.
Myth: New Construction Does Not Need Testing
Builders in some states are required to include radon-resistant features in new construction, but that does not mean every new home is automatically safe. Radon testing after move-in remains the only way to confirm whether those features are working as intended, and construction shortcuts or later renovations can compromise a home’s radon resistance even when it was built with the right materials.
Myth: A Quick Store-Bought Kit Is Just as Reliable as a Professional Test
Consumer test kits exist and can offer a rough sense of radon levels, but professional radon testing uses calibrated continuous monitors that account for temperature swings, airflow disturbances, and placement accuracy in ways a basic kit cannot. For real estate transactions specifically, most lenders and attorneys expect results from a certified tester rather than a self-administered kit, since the testing must meet specific chain-of-custody and calibration standards to be considered valid.
Myth: Testing Is Only Necessary When Buying or Selling
Real estate transactions are a common reason to schedule radon testing, but conditions inside a home change over time. Renovations that seal up previously leaky foundations, new HVAC systems that alter airflow patterns, or simply years passing since the last test are all reasons to test again even outside of a sale. According to New Jersey’s Department of Environmental Protection radon program, the agency recommends testing during the heating season when homes are typically sealed up tightest, which is also when radon levels tend to read highest.
What Actually Happens During a Test
A typical radon testing appointment involves placing a calibrated device in the lowest livable level of the home for a minimum of 48 hours. Once that period ends, results come back showing average radon concentration in picocuries per liter, along with a clear explanation of what the number means and whether mitigation is worth discussing.
Frequently Asked Questions
What radon level requires action? The EPA and New Jersey DEP both recommend mitigation at or above 4 picocuries per liter, though even lower levels carry some risk with long-term exposure.
How long does radon testing take? Most tests run for a minimum of 48 hours, with results available shortly after the monitoring device is retrieved.
Is radon testing required by law in New Jersey? New Jersey does not require sellers to test for radon during a home sale, though many buyers request it as part of their own due diligence, and certified testers are required by law to perform the work.
Can I test for radon myself? Store-bought kits exist, but professional testing uses calibrated equipment that meets the standards required for real estate transactions and produces more reliable results overall.
Radon does not announce itself, which is exactly why guessing is not a strategy worth relying on. If you want a clear answer for your Ocean County home, contact Funk Inspection Services and add radon testing to your visit.
