Radon Tests (Measurements) & Real Estate transactions:

What do the results mean?
When requested by the Buyer the Buyer’s Real Estate Agent typically writes into the purchase agreement that if the radon measurement is at or above the EPA’s action level of 4.0 pCi/L, the Seller will have the property mitigated for radon. If this is the case, and the results are 4.0 pCi/L or higher, the Seller pays for the mitigation. If the results are 3.9 pCi/L or less, the Seller does not pay. If the results are 3.9 pCi/L or less, the buyer can choose to mitigate, but at the buyer’s expense.

If the results of the radon test at a property you are interested in purchasing are high (4.0 pCi/L or above) fear not, radon mitigation systems are most often successful at reducing the radon inside the property to levels below 2.0 pCi/L.

When a property is involved in a real estate transaction, the optimal radon testing option is to have the radon test performed by a state-licensed radon measurement technician. Utilizing a licensed radon technician ensures that the radon test was conducted with professionally calibrated equipment. A licensed radon technician will follow the EPA protocols designed to achieve a non-biased measurement and minimize interference with the radon test. Time is a consideration in real estate transaction radon tests – the results from our measurements are usually available the same day the radon test ends.

Providing non-biased radon tests during real estate transactions is our focus. We understand the compressed time frame often present in a real estate transaction and strive to work within the time allotted for home inspections. We are familiar with the challenges that are possible during a contract negotiation and do our best to accommodate the specific situation.
