Radon Testing

Professional radon testing for home buyers, sellers and homeowners throughout Central New Jersey.

Radon is a naturally occurring radioactive gas that can accumulate inside homes. It is colorless, odorless, and tasteless, which means the only way to detect it is through professional testing.

The U.S. Environmental Protection Agency (EPA) recommends radon testing during real estate transactions to ensure the home does not contain elevated radon levels. Radon exposure is the second leading cause of lung cancer in the United States, making testing an important step when purchasing a home.

El Rey Inspections offers professional radon testing that can be scheduled with a home inspection or as a standalone service.

How Radon Testing Works

Radon testing is typically performed as a 48-72 hour short-term test placed in the lowest livable area of the home, such as a basement or first floor.

The testing device measures radon levels during the test period while the home remains under closed-house conditions. After the test is complete, the device is retrieved and the results are analyzed through a certified laboratory partner.

Clients receive clear documentation of the results along with guidance on next steps if elevated levels are detected.

When Radon Testing Is Recommended

Radon testing is commonly recommended:

  • During the purchase of a home

  • For homes with basements or crawl spaces

  • In areas known to have elevated radon levels

  • If the home has never been tested for radon

  • To confirm whether an installed radon mitigation system is working effectively

Radon levels can vary significantly from one home to another, even between neighboring properties, which is why testing each property individually is important.

Radon Testing With or Without a Home Inspection

Radon testing may be added to a home inspection or scheduled separately. Scheduling radon testing with your home inspection makes the process simple and efficient. The testing device is placed during the inspection and retrieved after the required testing period.

This allows buyers to obtain radon results within the timeline of their real estate transaction.
