The question of cost comes up whenever radon testing is part of a home sale. If you do not negotiate the testing or radon system into your real estate contract, chances are you will be the one to pay for it. In some cases, you can negotiate with the sellers. Many homeowners are willing to pay the cost of testing. In other cases, the owner may fund a credit or split the cost of testing with you.
If you own a single-family home, then you only need one radon mitigation system. A qualified contractor will install the system and the cost can be affected by different factors. In some homes, the radon system is simplistic, whereas others, the pipes might be complex.
