The EPA recommends that all houses, regardless of what radon zone the house is located in, be tested for radon during point of sale. The most common procedure for radon testing during real estate transactions is for the potential buyer to request the radon test as part of the overall home inspection. The radon test is generally a separate service and must be requested. If the radon test is 4 pCi/L or greater, the EPA recommends the potential buyer negotiate with the seller to have a radon mitigation system installed with the stated goal of bringing the radon level in the home below 4 pCi/L.
Radon test kits are placed in the lowest lived-in level of the home and left for a minimum of 3 days. After that time, the kit is sent to the laboratory for analysis. Once the results are received from the lab, you will be contacted with the results and I will advise you as to the next steps to be taken.
