Buyer's and Seller's Guide to Radon
On this page: I'm Buying a Home. What Should I do?
a. If the Home Has Already Been Tested for Radon... If you are thinking of buying a home, you may decide to accept an earlier test result from the seller or ask the seller for a new test to be conducted by a qualified radon tester. Before you accept the seller's test, you should determine:
The results of previous testing;
Who conducted the previous test: the homeowner, a radon professional, or some other person;
Where in the home the previous test was taken, especially if you may plan to live in a lower level of the home. For example, the test may have been taken on the first floor. However, if you want to use the basement as living space, test there; and
What, if any, structural changes, alterations, or changes in the heating, ventilation, and air conditioning (HVAC) system have been made to the house since the test was done. Such changes might affect radon levels.
If you accept the seller's test, make sure that the test followed the Radon Testing Checklist. If you decide that a new test is needed, discuss it with the seller as soon as possible. If you decide to use a qualified radon tester, contact your state radon office to obtain a copy of their approved list of radon testing companies.
