Short Answer
Radon is a naturally occurring radioactive gas that can seep into homes through the soil and foundation. It is the second leading cause of lung cancer after smoking. New Jersey has elevated radon levels in many areas, including Burlington County. Radon testing is recommended for all home purchases and is often required by lenders. Testing is simple and inexpensive. If elevated levels are found, a mitigation system can be installed for $800 to $1,500.
Radon is an invisible, odorless gas that comes from the natural breakdown of uranium in soil and rock. It enters homes through cracks in the foundation, gaps around pipes, and other openings. The EPA recommends taking action if radon levels exceed 4 picocuries per liter (pCi/L). New Jersey is in EPA Zone 1 for radon, meaning the state has the highest potential for elevated radon levels. Burlington County has areas with significant radon risk. Radon testing is a simple process. A home inspector places a small device in the lowest livable level of the home for 48 hours to several days. The test costs $100 to $200 as part of a home inspection. If the test shows elevated levels, a radon mitigation system can be installed. This system uses a fan and pipe to vent radon gas from beneath the foundation to the outside, where it dissipates harmlessly. Mitigation typically costs $800 to $1,500 and is highly effective at reducing radon levels. Ask the seller if the home has been tested and whether a mitigation system is already installed.

Radon is a serious concern in New Jersey, but it is also a solvable problem. I have seen homes with high radon levels that were easily mitigated for under $1,500. Do not let a radon test result scare you away from a home you love. I always recommend radon testing as part of the home inspection. If the levels are high, we can negotiate with the seller to install a mitigation system. Let us make sure your home is safe for your family.
