Do I Really Need Radon Testing in South Jersey?
(What Every Home Buyer Should Know Before Closing)
When you’re buying a home in South Jersey, there are plenty of things to think about—location, schools, neighborhood vibes, and of course, whether the house itself is in good condition. But there’s one invisible risk that many buyers overlook until it’s too late: radon gas.
You can’t see it, smell it, or taste it, but radon is a naturally occurring radioactive gas that can seep into homes from the soil. Over time, exposure to high levels of radon can increase the risk of lung cancer. In fact, the EPA ranks radon as the second leading cause of lung cancer in the U.S., right after smoking.
That’s why radon testing is one of the smartest investments you can make during the home inspection process.
Why Radon Testing Matters in South Jersey
South Jersey has a variety of soil types, older basements, and homes built without modern radon-resistant construction techniques. Even within the same neighborhood, one house may have safe levels while the house next door could have elevated radon.
Some key facts:
- Radon can enter through cracks in the foundation, sump pumps, crawl spaces, and even well water.
- Basements and lower levels are at the highest risk since they’re closest to the soil.
- New homes aren’t immune — even brand-new construction can have elevated radon levels.
The only way to know your home’s radon level is through professional testing.
How Radon Testing Works
At Tomlinson Home Inspection, we use charcoal canisters placed in the lowest livable area of the home. These remain in place for a set testing period, typically 48–96 hours, under closed-house conditions. Once the test is complete, the canisters are sent to a certified lab for analysis.
You’ll receive a clear report showing your home’s radon levels and whether they’re within the EPA’s recommended action level of 4.0 pCi/L.
What If the Radon Level is High?
If your test shows elevated radon, don’t panic. Radon mitigation systems are highly effective and relatively affordable compared to the long-term health risks of exposure. The key is knowing before you move in so you can address it—or negotiate repairs with the seller.
Why Add Radon Testing to Your Home Inspection
- It’s affordable peace of mind.
- It’s regionally important in South Jersey basements.
- It’s fast and accurate when paired with your home inspection.
- It could give you negotiating power if elevated levels are found.
Your Family’s Health Comes First
At the end of the day, a home inspection isn’t just about protecting your investment—it’s about protecting your family. Adding a radon test to your inspection package is a simple step that could make all the difference.
