Radon Testing for Real-Estate Transactions

Radon Pros can quickly and accurately get you the Radon Test information you need to efficiently close on your house! 


Consider the benefits of testing your house well before you put it on the market. If you can demonstrate that radon levels in your home are relatively low based upon the results of a properly conducted radon test, that may be a positive selling point. 

It may also save time and last minute hassles during the selling process. If you find a problem that should be fixed, you will have more time to get it done and may get a better price than if you wait until you are in the middle of the sale.

This will also ensure that the best possible information is used for making decisions about the presence of a radon problem and the need for corrective action.   



In Ohio, it is up to buyers to decide what they need to know about radon to be comfortable with the purchase of a home. 

If a home has been tested for radon, the buyer must decide if the results of past testing are acceptable. Issues to consider include the following: 

- Duration of test. For how many total days was the test conducted? Tests of less than 48 hours are not valid. 

- Type of test device used. Was the test device appropriate for the kind of test performed? 

- What area of the house was tested?  ODH recommends that radon test are conducted in the lowest level that is occupied on a regular basis.   

- Who performed the test? If a third party performed the test, were they licensed by the State of Ohio for this activity? Ohio law requires that a licensed radon tester be used.. 

- Have structural changes been made to the house? A new test should be done to reflect current conditions if structural changes were made or heating, ventilation or air conditioning systems were modified since the test was performed.  

- What level of radon was found? How does this compare to the level you feel comfortable with? How does it compare with the U.S. EPA guidance value of 4 pCi/L?
