Certified Radon Measurement for Homebuyers & Property Owners
Radon is a colorless, odorless radioactive gas produced by the natural decay of uranium in soil and rock. It enters homes through cracks in foundations, gaps around pipes, and other openings in contact with the ground. The U.S. Environmental Protection Agency identifies radon as the second leading cause of lung cancer after smoking, responsible for an estimated 21,000 deaths per year in the United States.
Radon levels vary from property to property — even neighboring homes can have very different readings. The only way to know whether your home has elevated radon levels is to test. The EPA recommends mitigation when levels reach 4 picocuries per liter (pCi/L) or higher.
New Jersey has some of the highest radon potential in the country. According to the NJ Department of Environmental Protection, approximately one in six homes tested in New Jersey has radon levels at or above the EPA action level. Elevated levels have been found in every county in the state, including Hudson County, Bergen County, Essex County, and Passaic County. Whether you're in a single-family home, a condo, or a multi-family building, radon testing is a critical step in understanding the air quality in your property.
We place a certified radon sampling device in the lowest livable area of the home under closed-house conditions. The test runs for a minimum of 48 hours to capture an accurate average reading. After retrieval, the sample is processed and results are delivered promptly. Our testing follows EPA protocols and New Jersey DEP requirements.
We offer radon testing as a standalone service or as an add-on to any home inspection. When combined with a home inspection, the radon test can begin on the same day as the inspection and results are typically available within a few days.
While New Jersey does not legally require radon testing during a real estate transaction, most buyers choose to include it as part of their due diligence. Sellers in New Jersey are required to disclose any known radon concentrations in the property. If elevated levels are found, radon mitigation systems can reduce concentrations effectively and are a common point of negotiation between buyers and sellers.
Having radon test results before closing gives you leverage in negotiations and ensures you and your family are moving into a safe environment.

Radon testing is available as a standalone service or combined with a home inspection or structural inspection in a single visit.
What is radon and why test for it?
Radon is a colorless, odorless radioactive gas produced by the natural decay of uranium in soil and rock. It enters homes through foundation cracks, sump pits, and gaps around pipes. The EPA estimates radon causes approximately 21,000 lung cancer deaths per year in the US — it is the second leading cause of lung cancer after smoking. Testing is the only way to know your radon level.
What radon level is considered unsafe?
The EPA action level is 4 picocuries per liter (pCi/L). The EPA also recommends considering mitigation at levels between 2 and 4 pCi/L. New Jersey has elevated radon risk statewide, and Hudson County properties — particularly basement levels and ground-floor units — should be tested.
How long does radon testing take?
We use short-term continuous electronic monitors placed for a minimum of 48 hours (as required for real estate transactions). The device is retrieved and results are typically available within 24 hours of retrieval.
Is radon testing required to buy or sell a home in NJ?
Not legally required, but strongly recommended and commonly requested by buyers. Many real estate attorneys and lenders include it as a standard transaction requirement. We provide a written report with measured levels and EPA comparison.
Can you combine radon testing with a home inspection?
Yes. We routinely combine radon testing with home inspection, termite inspection, and structural inspection in a single scheduling. The radon monitor is placed during the inspection and retrieved per the required testing protocol.
