Why Every Foundation Needs a Radon Test

Radon gas is one of the most underestimated health hazards in residential settings. Naturally produced from the breakdown of uranium in soil, it seeps into homes through cracks in the foundation, construction joints, and even through gaps around pipes. While radon is commonly associated with basements, that’s a dangerous misconception. Homes with slab foundations or crawlspaces are not immune to radon exposure.

Colorless, odorless, and tasteless, radon poses no immediate symptoms, which makes it easy to ignore. But long-term exposure significantly increases the risk of lung cancer. In fact, it’s the second leading cause after smoking. The only way to detect radon is through testing—something that’s simple, inexpensive, and widely available.

A radon test is one of the most cost-effective and overlooked ways to ensure long-term health in the home environment. Whether buying, selling, or maintaining a home, screening should be part of routine safety measures.

Short-term test kits are available over the counter, but professional testing provides more immediate and reliable results. If high radon levels are detected, mitigation systems can be installed to vent the gas safely out of the home. These systems are non-intrusive and highly effective.

Many regions require radon disclosure during home sales, but testing isn’t always mandatory. As a result, some buyers skip it. Even if the home is located in an area not typically associated with high radon levels, individual soil conditions and building characteristics can still allow for dangerous concentrations.

Crawlspaces in particular can collect radon if they’re unventilated or poorly sealed. The gas can then move up into living spaces. That’s why it’s important not to assume a slab or crawlspace eliminates risk.

Taking this simple preventive measure offers peace of mind and long-term health protection. When it comes to indoor air quality, what can’t be seen often matters most.
